In two previous articles we analyzed the design of the Pines Card in association with the disappearance and likely murder of Donna Lass on September 6th 1970. There are multiple possibilities, notably [1] The Pines Card contained nothing of value [2] The punch-hole fell over the Donner Memorial State Park, hinting at the young woman's name in similar fashion to the Monticello Card four months later, but had no directions to her burial site [3] The Pines Card contained clues to her name and burial site [4] The Pines Card contained directions to something Zodiac placed for investigators or the public to find, thereby (if found) bolstering the notion he was involved in her disappearance and murder. This could have been placed at a predetermined location prior to the mailing of the Pines Card. Or the most likely, [5] The Zodiac Killer crafted the Pines Card, but had absolutely nothing to do with her demise. This is the route we shall take in the following examination. 

I have come to the inescapable conclusion that the Zodiac Killer had nothing to do with the disappearance of Donna Lass from the Sahara Tahoe Hotel & Casino on September 6th 1970, and his willingness to suggest such an involvement was prescribed by the writings of the San Francisco Chronicle. On September 26th 1970, the disappearance of Donna Lass was extensively covered in a San Francisco Chronicle newspaper article entitled Nurse Vanishes -- A Tahoe Mystery. This must have been a goldmine for the Zodiac Killer, with all the ingredients contained in the article a compelling blend of circumstantial evidence just waiting to be picked. The Zodiac Killer knew that the circumstances surrounding the young woman's move from San Francisco to South Lake Tahoe was the perfect cocktail to convince investigators he was a viable candidate in her murder. The added benefit for the Bay Area killer was the suggestion of a link to the murder of another nurse, Judith Hakari, abducted on March 7th 1970, and later discovered in a shallow grave in Weimar. The Zodiac Killer could effectively link himself to two murders for the price of one. 

Many murders passed through the pages of the Chronicle newspaper, but this story had everything the killer required. Of course, he must have realized by now, that if he had mailed a communication immediately after the newspaper article, stating an involvement in her disappearance, then it would appear all too convenient, with his writings likely dismissed as a killer just latching on to the latest crime story. But by waiting months, as he had done with Kathleen Johns, his claims (in his mind) may carry more weight with investigators. In other words, the publicity had died down regarding the disappearance of Donna Lass, yet he still had the crime in the forefront of his mind even after six months, thereby adding validity to such a claim. 

Rubislaw32, a contributor to this site, touched on the idea that the March 22nd 1971 Pines Card may have been influenced by the abduction and murder of Judith Hakari. This idea carries much weight, when we consider the inspiration for the Pines Card was likely generated from the September 26th 1970 newspaper article six months earlier. The article was rich pickings for a killer who had previously murdered taxicab driver Paul Stine in the Presidio Heights area of San Francisco, so close to the Letterman General Hospital where Donna Lass had previously worked. The disappearance of a woman 150 miles from San Francisco, who had recent connections to San Francisco in the Presidio Heights district, must have been more than the Zodiac Killer could have wished for. Many disappearances and murders had occurred much closer to the Bay Area than the Lake Tahoe Mystery, but this one was covered comprehensively by the Chronicle and had the details the Zodiac Killer couldn't have failed to notice. We look for overlapping features in the Presidio Heights murder of Paul Stine by Zodiac, with the movements of Donna Lass and her eventual abduction from South Lake Tahoe, noting the location of the Letterman General Hospital with respect to the Presidio Park the killer escaped into. We then take the Pines Card depicting Incline Village and draw parallels to the crimes based on their locations, thereby concluding a possible Zodiac involvement in both. The problem being with this line of thinking, is the Zodiac Killer knew that these conclusions would be drawn when he created the Pines Card - because he had read the San Francisco Chronicle newspaper article and noted these comparisons himself. The Zodiac Killer was effectively forcing you into making an unwarranted connection, thereby bolstering a case for his involvement in the Donna Lass case. Everything required for the Pines Card sat in the September 26th 1970 pubication.          

All the Zodiac Killer required was a map of Lake Tahoe and the above newspaper article to create the perfect ruse. He had noted that a connection was being considered between the cases of Donna Lass and Judith Hakari, with the Sutter Hospital nurse having been discovered "buried in a shallow grave in the Sierra foothills of Placer County". Therefore, to give credence to his claims in the murder of Donna Lass (and possibly Judith Hakari), what better way than to place the pasted phrase of "around in the snow" upside down, to give the impression Donna Lass is buried in a shallow grave, and thereby tying the two cases together in modus operandi. Then place the pasted location of "Sierra Club" on the Pines Card to subconsciously plant the seed of a link to the "Sierra" of "the Sierra foothills of Placer County", where Judith Hakari's remains were subsequently unearthed. 

The newspaper article told us that Donna Lass worked at the Sahara Tahoe Hotel on the south side of the lake, so even a modicum of investigation to discover the location of the local police department, would allow the Zodiac Killer to direct the investigators "past the Lake Tahoe areas" to the the pine-laden wilderness and a likely burial site. Then came the pièce de résistance in the Pines Card, further forging a link between the Zodiac Killer, Donna Lass and San Francisco. The Zodiac Killer wanted investigators to draw the conclusion he had previously targeted Donna Lass in the Presidio area of San Francisco, and so driving them to the conclusion that he had traveled to South Lake Tahoe to complete his mission of killing the young woman Unfortunately, the Zodiac Killer may have overestimated the ability of police to discover the true meaning of "sought victim 12".

By using the past tense of seek in "sought", the Zodiac Killer was attempting to convince investigators he had previously trailed Donna Lass as victim number 12. The newspaper article gave us all the movements of Donna Lass, stating "Miss Lass became a first-aid nurse at the Sahara last June, living the previous five months in San Francisco and working at the Letterman General Hospital at the Presidio". The Zodiac Killer therefore knew that Donna Lass was in San Francisco in the January of 1970. He was only claiming 10 victims by April 20th 1970, and 12 victims by June 26th 1970, so it wasn't difficult for the Zodiac Killer to work out, that he could have "sought her as victim 12" before she left for South Lake Tahoe in June. The Zodiac Killer would have been seeking Donna Lass as victim number 12 sometime between April 20th 1970 and when she began her new job in June. By using the past participle of "seek", the Zodiac Killer was attempting to convince investigators his interest in Donna Lass had begun long before her disappearance - and in doing so, hopefully reinforcing a connection between San Francisco and South Lake Tahoe, with him as the common denominator between the two.

On March 19th 1971, the San Francisco ran an advertisement for condominiums at Incline Village by Lake Tahoe. The Zodiac Killer, having now waited the necessary time to authenticate his claim in the disappearance and murder of Donna Lass, lay the final piece of the jigsaw. His ruse was now complete.    

Here we will take a further look at the disappearance of Donna Lass from the Sahara Tahoe Hotel & Casino on September 6th 1970, attempting to discover the approximate area she was disposed of or buried. The last article on this subject pinpointed an area along California State Route 89 by Pole Creek Trailhead. The Zodiac Killer (if responsible for her murder) had previously made two phone calls to police, directing them to the crime scenes at Blue Rock Springs Park and Lake Berryessa. When the Pines Card was mailed on March 22nd 1971 it held directions within its design, such as "Sierra Club", "pass Lake Tahoe areas" and a punch-hole on the right side. The postcard was mailed to the San Francisco Chronicle and was addressing the police.

Here is a snippet from the South Lake Tahoe Police Department website: "The South Lake Tahoe Police Department (SLTPD) was formed July 1, 1967. The first home of the department was on the southwest corner of Lake Tahoe Boulevard at “D” Street. This is currently the present location of the City Corp. Yard. By the spring of 1969, SLTPD had 33 officers, seven civilian positions, and nine vehicles. We needed a bigger facility. So during the tenure of John Crow, the second Chief of Police at the helm of SLTPD, the Police Department moved to a month-to-month rental facility at Fremont Avenue and Mono Way. This structure is now the home of Nel’s Hardware store. This building was not constructed as a police facility, and eventually another move was needed. In April of 1973, the department moved to its current location in the El Dorado County Government Center, on Johnson Boulevard".
All three of these locations sit under the south side of the lake, so the instructions on the Pines Card to "pass Lake Tahoe areas" can only mean one of two things - the police needed to travel along the east side of the lake using US Route 50, towards Incline Village (the area depicted on the Pines Card), or travel along the west side of the lake, towards the Donner Memorial State Park and the Sierra Club at Clair Tappaan Lodge (also depicted on the Pines Card). See below. 

If the killer was living or vacationing on the south side of the lake, then he may very well have crossed paths with his target at the Sahara Tahoe Hotel & Casino, the Monte Verdi Apartments at 3893 Pioneer Trail (where Donna Lass lived), or somewhere close by. Whether he murdered Donna Lass first, then disposed of her body, or murdered her at the location he concealed her body, his most direct and convenient route of travel from the south side of the lake, is to "pass the Lake Tahoe areas" on the east or west side, via a major route. California State Route 89 and US Route 50 both skirt the lake on either side, and more importantly, head towards Incline Village and the Sierra Club at Clair Tappaan Lodge.

A newspaper article stated that 'the site depicted on the 'Pines Card' was from an advertisement published last Sunday by several newspapers. It was an artist's rendition of houses among the trees at a Boise Cascade Company project at Incline Village, where construction has just begun on the development. While much of the Sierra area is under several feet of snow, Incline Village has only two feet on the ground. Police went to the area to determine if a search is possible'. ​Chief Lauritzen added "There's no point to a search at this time. It's unlikely a victim would be uncovered before spring". This indicates that a search was to be initiated in this area, but it clearly failed to unearth the remains of Donna Lass. Parking your vehicle in the area of Incline Village under construction doesn't seem the most sensible choice to start digging a grave. When we consider that the July 13th 1971 Monticello Card revealed the name "Kathy" at the Oak Hill Memorial Park, and the Pines Card overlayed over the Sierra Club of Clair Tappaan Lodge revealed the name "Donna" (at the Donner Memorial State Park), it seems as though the Incline Village advertisement was used more as a template, rather than the actual burial site. The act of the Zodiac Killer adding "Sierra Club" to the postcard was clearly significant in this instance.  

Using a sprinkling of geographic profiling and the words on the Pines Card, the Zodiac Killer would be "past the Lake Tahoe areas" at Tahoe City, where California State Route 89 breaks away from the lake. He now has to effectively bury Donna Lass between Tahoe City and the Donner Memorial State Park by Truckee. Is he going to risk performing this task by Alpine Meadows or Olympic Valley?, or travel to the much more secluded area by Pole Creek Trailhead, which is exactly mid-distance between Tahoe City and the Donner Memorial State Park - this is the first and logical choice to avoid detection. There are some other turn off areas in this region of California State Route 89 where the Zodiac Killer could have disposed of a body, but mid-distance in a secluded area and sitting under his crosshairs on the Pines Card overlay, seems as good as any.   

If the Zodiac Killer was a native of the Bay Area and visited Lake Tahoe for recreational purposes such as hunting, fishing and hiking, then had he been responsible for the abduction and likely murder of Donna Lass on September 6th 1970, it seems a logical argument can be made for the killer disposing of his victim in an area he was familiar with. This area would be remote, free from prying eyes and somewhere the killer had previously frequented. Many killers will bury or conceal a victim in an area they feel comfortable spending the necessary time required for such a task, with limited or no fear of detection. If the Zodiac Killer was in Lake Tahoe for the wilderness and rugged terrain, he was probably familiar with the numerous hiking trails that surrounded the lake - and the many secluded areas at night, that would provide the perfect backdrop to bury a victim and lay a puzzle for the police. The burial site would likely be accessible by car, just off a hiking trail he knew well. It would be a reasonable distance from a main road, not too close to his residence, but not too far as to risk being pulled over with a body in his vehicle. The burial site of Donna Lass, as intimated by the March 22nd 1971 Pines Card fits all these criteria, and suggests (if the postcard is being truthful) that her body was hidden on the western edge of Lake Tahoe. The postcard itself, can be further be backed up with the accuracy displayed by the July 13th 1971 Monticello Card. For those of you unaware of this correspondence, here is a brief recap.  

The Monticello Card mimicked the Pines Card in the directional nature of the communication. The Monticello Card contained the phrases "in the woods" and "near Monticello", whereas the Pines Card stated "pass Lake Tahoe areas" and "Sierra Club". Both communications provided us with a specific location and directions, and it is my belief that both contained a punch-hole on the right-hand side of the card  The combination of a punch-hole and directions should indicate that both these postcards were designed as an overlay, pinpointing a specific location. The Monticello Card read "Near Monticello Shought Victims 21 ...... In The Woods Dies April". The card was describing the murder of Kathy Bilek, who was brutally stabbed in the Villa Montalvo woods on April 11th 1971 in Saratoga. The location he pinpointed as Monticello, was a few miles east of the crime scene - but more important - was the reason he chose the neighborhood of Monticello in the first place. Immediately alongside the neighborhood of Monticello sat the Oak Hill Memorial Park & Cemetery, where Kathy Snoozy was buried. The Zodiac Killer had previously claimed the murders of Kathy Snoozy and Deborah Furlong (San Jose) in his November 8th 1969 'Dripping Pen' card by the addition of "Aug" in his running total. The Oak Hill Memorial Park & Cemetery would have sat under the punch-hole on the Monticello Card. This punch-hole would not only be over a memorial park, but over a burial site. The only reason the Zodiac Killer identified this location in Monticello, was to reveal the name of Kathy, the namesake of Kathy Bilek - and the final clue to the identity of the murder victim portrayed in the Monticello Card. The Pines Card followed exactly the same pattern, with the punch-hole again falling over a memorial park and the name of an alleged murder victim - that of Donna Lass. When the Pines postcard is positioned over the Sierra Club of Clair Tappaan Lodge, the punch-hole falls exactly over the Donner Memorial State Park. The Zodiac Killer gave us a memorial to Kathy and Donna in both instances.

But was it really that simple? The Monticello clue - although it identified a burial site - was not the burial site of the young woman that the Monticello Card was designed around (that of Kathy Bilek). Moreover, it was a clue to the name of Kathy. The punch-hole in the Pines Card may equally have been designed to give us the name of Donna, but not specifically denoting where she was buried. So, let us take an in depth look at the March 22nd 1971 Pines Card.   

You will notice that the wording "Sierra Club" has been inadvertently or deliberately pinned to the largest tree, as to mimic a "flagpole" or "starting point". Directly opposite (and of equal size to the pasted text) the Zodiac Killer has placed the punch-hole. When the center of Sierra Club on the flagpole is positioned over the Sierra Club of Clair Tappaan Lodge, with the postcard overlayed onto a map, the punch-hole on the right side drops nicely over the entrance to Donner Memorial State Park. But nobody in their right mind (even Zodiac) would have contemplated burying Donna Lass so close to Interstate 80 and the Donner Pass Road. As stated above, the killer would likely dispose of the body with the least chance of detection, away from the major roads, and probably alongside a hiking trail he was previously familiar with.

There is only one route that fits the criteria of "pass Lake Tahoe areas" that runs directly from the south side of Lake Tahoe where Donna Lass was abducted from (Sahara Tahoe Hotel & Casino), to the area of the Donner State Memorial Park. From the Sahara Tahoe Hotel & Casino, a direct route from the crime scene to remote wilderness, could be achieved by taking US Route 50 and California State Route 89. It is approximately 30 miles from the casino along the south and west side of the lake, to the area I have identified. Furthermore, the area is alongside the Pole Creek Trailhead - a hiking trail the Zodiac Killer may have been familiar with. This location sits directly over the crosshairs of Zodiac on the Pines Card. I have drawn a green line from the location of the punch-hole (Donner Memorial State Park) to the crosshairs on the Pines Card. This green line straddles California State Route 89, with the crosshairs falling a few hunded metres to the west of Route 89, by the Pole Creek Trailhead, along Pole Creek Road. Shown here on Google maps.

This is obviously an estimation to the possible burial site of Donna Lass, but when we "pass the Lake Tahoe areas" on the west side of the lake, this trailhead presents itself. The Zodiac Killer could exit California State Route 89 just past the Silver Creek Campground and travel a few hundred meters along Pole Creek Road. This area offers quick egress from the Sahara Tahoe Hotel & Casino via US Route 50 and California State Route 89, and into remote isolation in as little as 40 minutes. More importantly, the Zodiac crosshairs fell over this area when the Sierra Club of Clair Tappaan Lodge and Donner Memorial State Park were aligned with the Pines Card. The Zodiac Killer pasted "pass Lake Tahoe areas" and "Peek through the Pines" next to the Zodiac crosshairs, so it is rather fortunate that Pole Creek Road is just past the Lake Tahoe areas on the western edge, and forged between the pine trees of California State Route 89 (see below).

In the history of cryptography, a grille cipher was a technique for encrypting a plaintext by writing it onto a sheet of paper through a pierced sheet (of paper or cardboard or similar). The earliest known description is due to the polymath Girolamo Cardano in 1550. His proposal was for a rectangular stencil allowing single letters, syllables, or words to be written, then later read, through its various apertures. The written fragments of the plaintext could be further disguised by filling the gaps between the fragments with anodyne words or letters. This variant is also an example of steganography, as are many of the grille ciphers. Wikipedia.

The Zodiac Killer began his letter writing campaign on July 31st 1969, when he mailed three portions of one cipher to the San Francisco Chronicle, San Francisco Examiner and Vallejo Times-Herald. However, it wasn't until October 5th 1970 that his communications took on a different appearance entirely, in which the Bay Area murderer began claiming he was "crackproof" and stated "sorry no cipher", with four out of the next five communications (if we include the Monticello Card) employing the notion of a grille cipher. The '13 Hole' Postcard, possibly using a "red cross" decoder (akin to the Dick Tracy red decoder) , to be punctured by the 13 holes on the card and overlayed onto the 340 character cipher. This would reveal the enciphered "paradice" and "slaves" bisecting the 340 cipher both horizontally and vertically along its mid-section. The "sorry no cipher" in a cross formation on the Halloween Card envelope, also overlayed onto the "paradice" and "slaves" on the rear of the card, to again point to the 340 cipher configuration and let us know that it was unfortunately "no cipher" (Zodiac's Halloween trick or treat reveal). This was explored in the Dick Tracy 340 Cipher article. 

The 13 holes overlayed onto the 340 cipher in a cross formation, taken from the '13 Hole' Postcard would reveal the hidden arrangement in the 340 cipher (similar to the depiction on the right, although portrayed with yellow squares as opposed to white punch-holes). This was the arrangement already present on the Halloween Card in reveal mode.

The '13 Hole' Postcard has 13 punch-holes in the fabric of the card, the Halloween Card has an eye peeking through the knothole in the tree, and the mask on the skeleton has two eyeholes. Then (if I am correct) we have one hole punched in both the March 22nd 1971 Pines Card and the July 13th 1971 Monticello Card, which when overlayed on a map by the Sierra Club of Lake Tahoe and the Villa Montalvo woods in Saratoga, would both reveal the name of the victim in both instances. The point being, we have a rudimentary grille cipher being employed or insinuated in four communications spanning through October 5th 1970 and July 13th 1971. The arrangement of "paradice" and "slaves" on the Halloween Card, and the punch-holes in every other card during this period, revealing something significant hidden beneath. The name of Donna and Kathy in the two 1971 postcards, and the hidden configuration in the November 8th 1969 340 cipher, derived from both October 1970 communications.

The grille cipher, even in its most rudimentary form, was implied or used through four of Zodiac's last five communications from October 5th 1970. I am completely confident that the Monticello Card is fashioned in exactly the same manner as the Pines Card, separated by less than four months, with the single punch-hole revealing the location of Donner Memorial State Park (Donna Lass) and Oak Hill Memorial Park & Cemetery (Kathy Snoozy) by the Monticello neighborhood of San Jose. Two locations, two victims and two names, all bound by two postcards. If these overlays didn't drop over these locations accidentally, then why should the cross design on the '13 Hole' Postcard and Halloween Card mimic the 340 cipher accidentally as well.

Was the Zodiac Killer inspired by the simple Dick Tracy grille cipher, or had he invested in the book The Codebreakers - The Story of Secret Writing by David Khan, released the year before the Zodiac attacks began on December 20th 1968? It is without much doubt, that the grille cipher featured heavily in his final two communications of 1970, even though one could argue that the single holes punched into the 1971 postcards are more representative of an overlay, rather than a decryption technique - yet in every instance, a message was revealed through the punch-holes.

Cragle, a conrtributor to the Zodiac Killer Site forum, brought up an extremely valid connection to the Lake of the Pines development in Auburn, Placer County with respect to the Boise Cascade Company. He stated "As we know Donna Lass was taken from Lake Tahoe, a card was then sent implying that she was buried at Incline Village on the north shore of the lake. Also a Christmas card was received with the quote 'St Donna & Guardian of the Pines'. Now what is the connection, Judith Hakari was abducted and then found near Weimar, CA. Weimar is next to Lake of the Pines. At the time Lake of the Pines was a brand new housing development which was still in the process of being finished. The developers of Lake of the Pines were the very same company that was responsible for Incline Village".  

Western Lake Properties purchased three large ranches to create Lake of the Pines, including the Henry Pilliard spread, which was originally settled in 1860 on 1200 acres, and still had descendants running cattle on it well into the middle of the 20th century. Bulldozers carved into a natural basin of meadows and pasture land rimmed by pine forests and oak woodlands to cut out the imprint of the lake. The reservoir's dam was completed in 1966 and the 230-acre reservoir filled by April of the following year. In 1969, the Boise Cascade development company purchased the project, marketing the lots to older workers in the Bay Area and Southern California. While the developer continued construction on the common amenities, contractors were busy constructing spec houses aimed at retirees who were scaling down, and building custom vacation homes for buyers planning to use them as weekend getaways or future retirement villas. link.

On March 22nd 1971, the Zodiac Killer mailed a postcard insinuating his involvement in the disappearance and likely murder of Donna Lass in South Lake Tahoe on September 6th 1970. A newspaper report in March 1971 stated "the site depicted on the 'Pines Card' was from an advertisement published last Sunday by several newspapers. It was an artist's rendition of houses among the trees at a Boise Cascade Company project at Incline Village, where construction has just begun on the development. While much of the Sierra area is under several feet of snow, Incline Village has only two feet on the ground. Police went to the area to determine if a search is possible'. ​Chief Lauritzen added "There's no point to a search at this time. It's unlikely a victim would be uncovered before spring".
The body of Donna Lass was never recovered in the location of Incline Village despite an extensive search. However, the forum thread created by Cragle may have opened the door to another possibility regarding the Boise Cascade Company.

The similarity between the cases of Donna Lass and Judith Hakari cannot be overlooked, despite the fact the Zodiac Killer was likely responsible for neither. But that doesn't preclude him from claiming his involvement in both, through a link to the Boise Cascade Company. Choosing an advertisement from the newspapers about condominiums, appears a rather banal choice by the Zodiac Killer when we consider the flamboyant Halloween card that preceded it. If it wasn't chosen for the location of Incline Village as the burial site of Donna Lass, then was it chosen to supply a connection to a previous victim, thereby hinting he was responsible for both? If the newspapers could make the connection from Donna Lass to the murder of Judith Hakari, abducted from the Markston Apartments in Sacramento on March 7th 1970, then the Zodiac Killer was certainly not averse to pushing investigators down the same train of thought.

Both Lass and Hakari were nurses, abducted shortly after finishing their shift at the Sahara Tahoe Hotel and Sutter Hospital respectively. How long they were kept alive from the moment they were snatched is unknown, but the suspicious phone calls after the disappearance of Donna Lass stating she had been called out of town due to a family illness, may have served the purpose of buying time by her abductor. If the same perpetrator was responsible for both, could he have traveled Interstate 80 from Lake Tahoe to Sacramento, and therefore was familiar with forest regions spanning both. Judith Hakari's body was eventually discovered nearly two months after her disappearance (April 25th 1970) buried in a shallow grave aside Ponderosa Way. Could her killer have disposed of Donna Lass somewhere in this region? 

The July 13th 1971 Monticello Card contained extremely similar pasted phrases to the March 22nd 1971 Pines Card, stating "Near Monticello Shought Victims 21 ...... In The Woods Dies April". The postcard was referring to the April 11th 1971 murder of Kathy Bilek in the Villa Montalvo woods, near the neighborhood of Monticello in San Jose. The Zodiac Killer chose Monticello for one reason alone - it sat alongside the burial location of one of his previously claimed victims, Kathy Snoozy. He had claimed her murder under the month of "Aug" in the November 8th 1969 'Dripping Pen' Card, killed in San Jose on August 3rd 1969 along with her friend Deborah Furlong. The funeral services and burial of Kathy Snoozy were held at Oak Hill Memorial Park at 300 Curtner Avenue, right next to the neighborhood of Monticello. This is why the Zodiac Killer chose "near Monticello" rather than any other location closer to Villa Montalvo. He was not only pinpointing this location to suggest he had a hand in the murder of the San Jose teenagers, but specifically chose the area by the gravesite of Kathy Snoozy because her forename was identical to that of Kathy Bilek. Not only was Kathy Bilek murdered in April, in the woods, near Monticello - but her name could be inferred in the Monticello card from the Oak Hill Memorial Park burial site of her namesake. The Pines Card may have served a similar function through the choice of Boise Cascade. It was discovered that by placing the Sierra Club phrase over the Sierra Club of Clair Tappaan Lodge (just west of Lake Tahoe), the punch-hole fell over the Donner Memorial State Park.

The March 13th 1971 'Los Angeles' Letter was mailed nine days prior to the Donna Lass Pines Card, so it was equally interesting to find a loose connection in this communication also. 

The Vanishing Point film, which previewed in the January of 1971, had the usual trailers, and was released to the general public on March 13th 1971, the exact mailing date of the Los Angeles letter, presumably authored by the Zodiac Killer. Here is some of the wording from the trailer: "They want to get him and put him away, but there'll have to catch him first". The author of the Los Angeles letter stated "If the Blue Meannies are evere going to catch me, they had best get off their fat asses + do something". The trailer of the film continued with a radio host from KOW reporting the chase "And there goes the Challenger being chased by the Blue, Blue Meanies on wheels". So, was the Vanishing Point trailer the inspiration for the March 13th 1971 Los Angeles letter, with its mailing date deliberately manufactured to marry up with the release date of the film? The Los Angeles letter arrived six months after the disappearance of Donna Ann Lass, who vanished close to the end of her shift at the Sahara Tahoe Hotel & Casino, never to be seen again.

The final scene in the Vanishing Point movie was filmed in Cisco, Utah, but in the film it was portrayed as Cisco, California. This is the location that the film's main character, Kowalski, met his death. Cisco, California is 11.7 miles west of Clair Tappaan Lodge, the Sierra Club identified by former detective Harvey Hines as the location depicted on the Pines Card. Cisco was 15 miles west of the Donner Memorial State Park. In another strange quirk of fate, the officer overseeing the conclusion to Kowalski's death after he ran his 1970 Dodge Challenger into the roadblock of bulldozers, was the character Deputy Collins played by Robert Donner. 

The Zodiac Killer linked the Monticello Card to a victim he had previously claimed (Kathy Snoozy) by choosing the location of Monticello - so had he done the same using the location of the Boise Cascade Company developments situated at Incline Village and Lake of the Pines? The Boise Cascade development at Lake of the Pines were marketing the lots to older workers in the Bay Area, which may have come to the attention of the Zodiac Killer from the newspaper coverage - and why he ultimately chose this particular advertisement regarding Incline Village. Lake of the Pines is situated just 4.4 miles west of the burial site of Judith Hakari alongside Ponderosa Way. Was the Zodiac Killer inferring a link to another victim through this advertisement, bearing in mind he had already been linked to the Hakari murder by the newspapers - or is it just a case of finding faces in the clouds?        

Donna Lass lived at 4122 Balboa Street, San Francisco, just west of the Presidio, where she worked as a nurse at the Letterman General Hospital. It was the Presidio where Zodiac was seen entering just minutes after the murder of taxicab driver Paul Stine on October 11th 1969, never to be seen again. On June 5th 1970, Donna was preparing for her move to South Lake Tahoe to begin a new job at the Sahara Tahoe Hotel & Casino on June 6th 1970, temporarily moving in with Ann and Larry Lowe at 4054 US Highway 50, before taking up residence at the Monte Verdi apartments on 3893 Pioneer Trail Road. Exactly three months later, she would mysteriously disappear at the end of her shift on September 6th 1970. Her whereabouts have never been ascertained, but it is presumed she was murdered shortly after her abduction. Six months later, on March 22nd 1971,  a postcard arrived at the San Francisco Chronicle containing a punch-hole and five pasted phrases - one of which stated "sought victim 12". Many have claimed this postcard was at the hands of a hoaxer because the victim total took a retrograde step, although it should be fairly obvious that somebody who was prepared to cut and paste this card, punch a hole and scallop the edges - who was equally determined to mimic the Zodiac Killer - would certainly have known the killer had already claimed 13, 14 and 17+ victims in his previous four communications. The past participle of the verb seek should have been the clue.

The sister card to the March 22nd 1971 offering, arrived on July 13th 1971 and was dubbed the Monticello Card. It was designed in similar fashion, stating "Near Monticello Shought Victims 21 ...... In The Woods Dies April". The author had once more used the past participle of the word seek, with the slight variation of "shought" - but was again suggesting that the victim had at one point in time been targeted. Kathy Bilek was being claimed by the Zodiac Killer, despite the fact that this murder had already been attributed to Karl Francis Werner. See here for details. 

The Monticello Card was postmarked July 13th 1971 and Kathy Bilek was targeted and murdered in the Villa Montalvo woods in Saratoga on April 11th 1971. Therefore, a Zodiac Killer stating "shought victim 21", would be referring to a victim he targeted 94 days ago. In other words, he "shought" Kathy Bilek on April 11th 1971. This total of 21 would fit correctly in the Zodiac Killer sequence, because he claimed 17+ victims on March 13th 1971 when he mailed the Los Angeles letter. Let us apply this template of 94 days to the disappearance and murder of Donna Lass on September 6th 1970, to discover whether the "sought victim 12" would now fall into line with her being targeted in the Bay Area when she worked at the Letterman General Hospital.

If we deduct 94 days from the date of her disappearance on September 6th 1970, we get June 5th 1970 - the exact day she prepared for her move to South Lake Tahoe to begin work at the Sahara Tahoe Hotel & Casino. Was the Zodiac Killer effectively hinting that he had "sought" Donna Lass as victim number 12 in the Bay Area, but she had moved from San Francisco on June 5th or 6th 1970, thereby thwarting his plans? The April 20th 1970 '13 Symbol' cipher claimed 10 victims, which wasn't updated on the April 28th 1970 Dragon Card. The June 26th 1970 Button Letter had claimed 12 victims. Therefore, if Donna Lass had been "sought" as victim 12 by the Zodiac Killer, it would have fell somewhere between April 28th 1970 and June 5th 1970. Effectively, we are looking at the preceding month (May 1970) to when she packed up and left for South Lake Tahoe. This month could be pivotal in revealing the identity of the Zodiac Killer through the circles of Donna Ann Lass. Who were her close friends, colleagues or 'admirers' during this short window of time?

Through alliances with the Monticello Card, the Pines Card was almost certainly a Zodiac Killer offering - and therefore inconceivable that the phrase "sought victim 12" was simply a 'schoolby error' on behalf of the killer. Equally, a copycat with even the remnants of a brain, couldn't have made such a nonsensical mistake having made all the effort to mimic a Zodiac Killer communication in the first place. It wasn't like he was short of newspaper coverage. The retrograde step of the victim count to 12, in combination with the past tense of "sought" certainly wasn't a mistake - it was chosen for purpose. Possibly the day the Zodiac Killer's plans were scuppered as Donna Lass upped sticks and headed out of state to South Lake Tahoe.

There are innumerable theories on the October 27th 1970 Halloween card, including here on this site, but none have adequately explained the strange symbol on the upper left corner of the envelope or the foot of the card inner. The cattle branding was a good idea, yet it conveniently ignored the four dots present in the design. In both instances, on the envelope and card, the symbol was followed by the letter Z. This lends credence to the notion, it represents a statement followed by his signature. The Zodiac, from November 8th 1969 to March 13th 1971, was fairly consistent in giving us a running victim total, with the only two notable exceptions being the April 28th 1970 Dragon card and the July 24th 1970 Kathleen Johns letter. With respect to the Dragon card, he had given us 10 victims only eight days earlier, so clearly there was no update on the total, and with respect to Kathleen Johns, she survived the encounter so no update was necessary. The Zodiac Killer repeated the victim count of 13 on the October 5th 1970 '13 Hole' postcard because his previous letter proclaiming 13 victims had not been published in the newspapers at this juncture, The July 26th 1970 Little List letter proclaimed 13 victims, while the October 27th 1970 Halloween card issued us with the number 14, indicating that victim 14 possibly lay between these two dates.      

We know the Zodiac Killer was responsible for 5 victims - the rest he inferred by increasing his total periodically. The only victim we know of between July 26th 1970 and October 27th 1970 that was subsequently claimed by Zodiac, was Donna Ann Lass, who disappeared from the Sahara Tahoe Hotel & Casino in the early morning hours of September 6th 1970. We know he was insinuating his involvement in her disappearance because of the March 22nd 1971 Pines card mailed to Paul Avery at the San Francisco Chronicle, just like this communication. 

However, although believed murdered, the body of Donna Lass has never been found - and on October 27th 1970 she was still classified as missing. Therefore, any running victim total on this card may reflect the current status regarding Donna Lass within its design. The March 22nd 1971 Pines card teased us with the possible location of where her burial site may be found, by placing a punched hole in the top right corner. Why should this communication be any different, when we consider the design in the top left corner of the envelope and the same design placed within the card, not withstanding, that victim 14 should have fell between July 26th 1970 and October 27th 1970, which the disappearance of Donna Lass did. 

The numerous eyes spattered over the entire card should have told us we need to be looking for something - or more specifically - looking for victim number 14. I have considered the possibility of the symbols being interpreted as "Zodiac Victims Fourteen" or "Zodiac Fourteen", but this doesn't adequately explain the four dots present in the design. It also doesn't make any sense with respect to the letter Z accompanying it on either the envelope or card inner. The phrase created would read "Zodiac Victims Fourteen, Zodiac" or "Zodiac Fourteen, Zodiac". There has to be another answer, incorporating the design of the card and the 13 eyes splashed all over its face. The 13 eyes suggestive of only 13 deceased victims, looking for the 14th victim. The Zodiac Killer would eventually claim his involvement in the disappearance of Donna Lass, so the Halloween card "looking for the fourteenth victim" makes perfect sense with respect to the dates. Take a look at the card below.   

If we follow the green, yellow and blue rectangles in that order, it can be seen how this spells out "look for fourteen". If we follow the green, yellow and blue circles in that order, it can also be interpreted as "look for fourteen". The first part of the strange symbol isn't structured like the letter Z or the number 7, because the top angle is ninety degrees. However, it can be interpreted as the letter L. The four dots representing "four" or "for", with the F representing 14, as displayed on the hand of the skeleton and by the 4-TEEN above it. The phrase now reads coherently: "look for fourteen, Zodiac". In view of the fact that Donna Lass went missing on September 6th 1970, and his later Pines card communication insinuating his involvement in her disappearance, the running victim total (placed into this design) reading "look for fourteen, Zodiac" isn't so far-fetched.  

With both of these communications (Pines and Halloween) being addressed to Paul Avery, it is easy to consider a correlation between the two, even if the Zodiac Killer was behind the disappearance of Donna Lass or not. The "sought victim 12" attribution on the Pines card a whole different story.

Using some material from previous articles, here we will show how the March 22nd 1971 'Pines' postcard was designed to pinpoint the burial location of Donna Lass by overlaying it on a map. That location is Donner Memorial State Park - but whether or not she can be found here is another matter. The reason I believe this was the meaning behind the 'Pines' card, is because the Zodiac Killer mailed an extremely similar card just under 4 months later. The 'Monticello' postcard was postmarked July 13th 1971 and also contained pasted words on its face with familiar language. These postcards were designed with respect to Donna Lass, who disappeared from the Sahara Tahoe Hotel on September 6th 1970, and Kathy Bilek, who was murdered in the Villa Montalvo woods on April 11th 1971.  ​

The Pines card: [1] Sierra Club [2] Sought Victim 12 [3] Peek through the pines' [4] pass Lake Tahoe areas [5] around in the snow.
The Monticello card: [1] Near Monticello [2] Shought Victims 21 [3] In the woods [4] Dies April. 

​It is my belief that the 'Monticello' card, not only had some woods or trees on its face, but had a punch-hole in the top right corner, exactly like the 'Pines' card. Both of these punch-holes designed to sit over the burial location of two victims claimed by the Zodiac Killer, but not necessarily Kathy Bilek despite the postcard being designed with her in mind. Both postcards contain helpful directions - and both lead to a memorial for two claimed Zodiac victims. It may be helpful to read a previous article entitled The Story of San Jose, before proceeding. 

The following is an excerpt from the unreleased 120 page Harvey Hines report, regarding his investigation into the missing Donna Lass: "After studying the card, I drove to Nordin, located on old Highway 40, north of Lake Tahoe, and found the SIERRA CLUB. I learned the club was not called the Sierra Club. It was named the Claire Tappaan Lodge and it was a private club for Sierra Club members only. I believed if I followed the directions on the postcard I would find Donna Lass' grave. I believe she was buried near the Sierra Club and most likely on the Donner Ski Ranch". 

​I believe Harvey Hines had the right idea, because Donner Ski Ranch is directly in line on the east-west axis with Clair Tappaan Lodge, exactly as "Sierra Club" is with the punch-hole on the 'Pines' card. But I have reached the conclusion that the destination isn't the Donner Ski Ranch, rather the Donner Memorial State Park. The reason lies in the wording "Donner Memorial", a bleak reference to her claimed burial site. If we "pass the Lake Tahoe areas" traveling west, we do reach the "Sierra Club" of Clair Tappaan Lodge depicted on the postcard. If we now position the 'Pines' card into place over a map, it can be seen that "Sierra Club" sits over Clair Tappaan Lodge (which can be seen from the road if we "peek through the pines"), and the punch-hole sits directly over the Donner Memorial State Park.  

I have now designed the 'Monticello' card to what I believe it probably looks like. Using exactly the same process as the 'Pines' card, we now have to follow its directions. In this instance, we know the murder victim referenced in the postcard was Kathy Bilek, murdered in April, in the woods, near Monticello (because the neighborhood of Monticello is 9 miles east of the Villa Montalvo woods). So (if it exists) what would the punch-hole in the top right corner of the Monticello card be directing us to this time? It is another clue to the identity of the murdered victim in the 'Monticello' card - by association with a previously claimed Zodiac victim.

​If the 'Monticello' card is to stay true to the 'Pines' card, the punch-hole must fall over another "memorial" with a potential name. The Pines card sat over a "Donner Memorial", so the 'Monticello' card must sit over a "Kathy Memorial". Using the same technique as above we will place the location of "near Monticello" over Villa Montalvo woods (because it's situated near Monticello). The punch-hole in my design would now sit over the Oak Hill Memorial Park & Cemetery by the Monticello neighborhood, where Kathy Snoozy is buried. The Zodiac Killer claimed the murders of Kathy Snoozy and Deborah Furlong in the November 8th 1969 'Dripping Pen' card as "Aug". This was the final clue in the 'Monticello' card, giving us the forename of Kathy Bilek by association with Kathy Snoozy, allied with the word "memorial" once again.   

I would like to expand on a previously discussed topic, regarding two cards likely mailed by the Zodiac Killer on March 22nd 1971 and July 13th 1971, dubbed the 'Pines' and 'Monticello' cards respectively. The March 22nd 'Pines' card contained the phrases [1] Sierra Club  [2] Sought Victim 12  [3] Peek through the pines  [4] pass Lake Tahoe areas and [5] around in the snow. The 'Monticello' card stated "Near Monticello Shought Victims 21 ...... In The Woods Dies April." One can see the similarities, with "sought" and "shought", "woods" and "pines", as well as "near Monticello" and "pass lake Tahoe areas". They were both directions to the location of a murder victim, but crucially, both postcards held the victims forenames within the design of each. They were so cleverly designed, it is difficult to believe they were not authored by the same individual, with two words linking both cards - Memorial Park. A memorial park is a designated area for remembrance of the departed. 

In the case of the 'Pines' card, the author chose a postcard of "an artist's rendition of houses among the trees at a Boise Cascade Company project at Incline Village, where construction has just begun on the development". He then directed us to "pass lake Tahoe areas" to an area by the "Sierra Club". If we follow these simple instructions we find ourselves at two locations in close proximity. The first is Clair Tappaan Lodge on Donner Pass Road - but more importantly - the second is Donner Memorial State Park (preserving the site of the Donner Camp, where members of the ill-fated Donner Party were trapped by weather during the winter of 1846–1847, resulting in 39 deaths). Bearing in mind the 'Pines' card was thought to have been mailed by the murderer of Donna Ann Lass, this may be the motivation behind its design. The author was pointing us towards the Donner Memorial to signify the forename of his murder victim. Of course, this could be a simple coincidence and not the intended meaning behind the postcard. Therefore, if we can find the identical design or meaning within its sister card, mailed on July 13th 1971 (just 4 months later), then we can just call it a double coincidence, or quite possibly accept that the designer fashioned them both with the intention to give us the forename of the murdered women in question.

The July 13th 1971 'Monticello' card stated "Near Monticello Shought Victims 21 ...... In The Woods Dies April." So we need to be looking for a woman who was murdered in April, in the woods and near Monticello. On Sunday, April 11th 1971, Kathy Bilek (18) visited Villa Montalvo in Saratoga, having planned to read a paperback book (The Gabriel Hounds) and engage in a spot of bird watching​ in the seclusion of a remote, wooded portion of the park, near a small stream. Her body was found the next day by her father, Charles, while Santa Clara County Sheriff's deputies searched nearby. She had been stabbed 17 times in the back and 32 times in her chest and stomach. Villa Montalvo is situated 9 miles west of the neighborhood of Monticello. The author of the 'Pines' card directed us to a Memorial Park called Donner. In the case of the 'Monticello' card, the author didn't need to direct us to her body, because she wasn't missing - and therefore we have to discover the purpose behind him choosing Monticello. This has to be the clue to the woman's forename, as well as the destination of a Memorial Park, if we are to satisfy the template of the 'Pines' card. 

Fortunately for us, another coincidence exists. Sitting in the Monticello neighborhood is Oak Hill Memorial Park, where one of Zodiac's previous claimed victims is interred. The Zodiac Killer insinuated his involvement in the brutal stabbing of Deborah Gaye Furlong (14) and Kathy Ann Snoozy (15), who were found murdered on August 3rd 1969 in the Bay Area of San Jose. By writing "Aug" on the November 8th 1969 'Dripping Pen' card, he was effectively laying claim to the Furlong and Snoozy murders - and the very reason he chose the location of Monticello on the July 13th 1971 postcard. Not only was Kathy Snoozy buried at Oak Hill Memorial Park, but she shared the same forename as Kathy Bilek. The Zodiac Killer was leading us towards a memorial park and forename in both postcards - Donna and Kathy.

Just like the July 13th 1971 Monticello card, giving us clues and directions to the murder of Kathy Bilek in April, near Monticello in San Jose, California, the March 22nd 1971 Pines card, in similar fashion, may have been designed to direct us to the deposition or burial site of Donna Ann Lass (25), who disappeared from Stateline, Nevada on September 6th 1970 having finished her shift that day at the Sahara Tahoe Hotel. Harvey Hines, a retired detective from Groveland, believed that Donna Lass was likely buried on the Donner Ski Ranch. He stated "After studying the card, I drove to Nordin, located on old Highway 40, north of Lake Tahoe, and found the SIERRA CLUB. I learned the club was not called the Sierra Club. It was named the Claire Tappan Lodge and it was a private club for Sierra Club members only. I believed if I followed the directions on the postcard I would find Donna Lass' grave. I believe she was buried near the Sierra Club and most likely on the Donner Ski Ranch. I would later have the pictures of the Sierra Club developed. Then using a copy of Zodiac's card, I cut out the phrases he had pasted on his card. Using these phrases, I overpasted them on the copy of the Sierra Club picture. It was striking similar to the original card." [see below left].
​   

​A newspaper article stated that "the site depicted on the 'Pines Card' was from an advertisement published last Sunday by several newspapers. It was an artist's rendition of houses among the trees at a Boise Cascade Company project at Incline Village, where construction has just begun on the development. While much of the Sierra area is under several feet of snow, Incline Village has only two feet on the ground. Police went to the area to determine if a search is possible".

If we use the directions given by the card from Incline Village, it tells us to "pass Lake Tahoe areas". To pass the areas of Lake Tahoe we have to travel westward, until we reach Clair Tappaan Lodge, "a private club for Sierra Club members only". 

Howard Davis, a contributor to the ZodiacKiller.com message board can pick up the story here: "Incredibly, her [Lass] grave remained hidden until August 1976, when retired Norden postmaster Otto Fredricks is believed to have found it on Donner Summit. He was hiking past the SIERRA CLUB'S Claire Tappan Lodge, near Norden, when he came across the intricately contrived wooden symbols alongside the path: in the center was a triangle around a cross containing 13 stones, and that was surrounded first by a six foot square and then by a circle of wood with a 14 foot diameter". The October 5th 1970 '13 Hole' postcard contained 13 punch holes and a red crucifix.

When they dug near the location of Clair Tappaan Lodge they found a pair of green tinted glasses, similar to a pair believed to have been worn by Donna Lass. It is not known for certain whether these glasses belonged to Donna Lass, or that the configuration was constructed by her murderer. Some believe the stone and wood configuration to be Rosicrucian in design, whereas 'The Foreigner' thought that Harvey Hines had misread the finding and it was a YMCA "Ragger’s Point" creation. Nevertheless, it is curious that "pass Lake Tahoe areas" takes us to the "Sierra Club" members of Clair Tappaan Lodge along Donner Pass Road, where we can "peek through the Pines" at the entrance to the lodge, and find some g(lass)es buried in the ground. The entrance to Clair Tappaan Lodge looks extremely similar to the depiction of the 1974 Christmas card mailed to Mary Pilker, Donna Lass' sister.​ Once inside the grounds we search "around in the snow". This can be interpreted as "a round in the snow" meaning "a circle in the snow". The circle of wood containing the crucifix. The alternative to finding meaning in the phrases pasted on the Pines card, is to believe the author pasted the text for no reason whatsoever. The two communications immediately after the Donna Lass disappearance were the '13 Hole' postcard and the Halloween card, each containing an inference to the number 13. The punch holes in the October 5th 1970 '13 Hole' postcard from the front side, arranged in a 10:3 formation (October 3rd), which could specify when he arranged the wood and stone configuration, meaning look for 13 in the form of a circle. The following Halloween card using 13 eyes in the design, telling us to look for 13. However, it must be stressed, that searching for clues and meaning behind such communications is down to the interpretation of the observer, with the above ideas often finding a resting place in the ever expanding graveyard of Zodiac theories. 

The Monticello card was mailed four months later, by somebody purporting to be the Zodiac Killer, and referencing the murder of Kathy Bilek in San Jose on April 11th 1971.

San Jose is home to the "Rosicrucian Egyptian Museum, devoted to Ancient Egypt, located at Rosicrucian Park in the Rose Garden neighborhood of San Jose, California, United States. It was founded by the Ancient Mystical Order Rosae Crucis (AMORC). The Rosicrucian Order continues to support and expand the museum and its educational and scientific activities. The museum holds the largest collection of ancient Egyptian antiquities in the Western United States, and is located next to the Rosicrucian headquarters". Wikipedia. The museum also had a purpose-built planetarium, where a budding Zodiac could add a knowledge of astronomy and the night sky to his search for the afterlife.  

"Rosicrucian Grand Master Julie Scott talks about the ancient Egyptian concept of the afterlife and shows us around the Rosicrucian Egyptian Museum in San Jose California". link.

But what if the murderer of Donna Lass added further directions using the crucifix, triangle, square and circle symbols as clues. Harvey Hines believed Donna Lass "was buried near the Sierra Club and most likely on the Donner Ski Ranch". So, were the symbols somehow related to the Donner Ski Ranch? Had the murderer of Donna Lass occasionally vacationed at Lake Tahoe, using the trails of Donner Ski Ranch? From 1964 to 1968 ski trails were rated on difficulty using a colored triangle, square and circle. Did the designer of the stone and wood configuration place the crucifix within the triangle, square and circle, using the glasses, to signify that Donna Lass was buried on Donner Ski Ranch along one of the trails? If the bottom left of the Pines card is placed over Clair Tappaan Lodge, the punch hole in the top right corner is facing the northeast, exactly where the ski lifts and trails are located. Was this the deduction of Harvey Hines? 

I would have to say that 'The Foreigner' is most likely correct, with the wood and stone configuration likely created by somebody other than the author of the Pines card (or Zodiac), and most probably a Ragger's Point creation. However, this doesn't preclude the Zodiac or an impostor using a pre-existing configuration as a burial site for the glasses. The wood and stone configuration would have been a perfect marker to direct the police towards, using the Pines card phrases from Incline Village.     

The following will again be a little bit of mathematical trickery regarding the 'Halloween', '13 Hole' and 'Pines' cards- placing the number 888 (Jesus) alongside each and every one.  From the 408 cipher split into three lines of 8, the 'near Zodiac' on the 20th line of the 340 forming 888, the three 8's on the '13 Symbol' cipher, coupled with the same code being used to find 444 in the final two ciphers, we will now move on to the final three cryptic cards in the Zodiac repertoire. To understand this presentation, it is important to read two previous articles 'The Bible Code of a Killer' and '340 Cipher-Embedded Symmetry'.  However, it must be stressed that this is not claiming a definitive solve to the Zodiac mystery and must be viewed with a health warning.

​In every correspondence mentioned above, it was claimed the Zodiac was attempting to place his name alongside the name of Jesus, the savior of souls for the afterlife: "All the (people) I have killed will become my slaves. I will not give you my name because you will try to slow down or stop my collecting of slaves for my afterlife." He wouldn't give us his name, but he may have given us Jesus. Here is the next cryptic correspondence with two unusual features, using the identical code employed to find 444 in both the final two canonical ciphers. The Zodiac again places his name alongside Jesus in the form of a messiah complex (also known as the Christ complex or savior complex).
Using the Zodiac code above, it was applied to the '13 Hole' postcard below, giving out the figures 43+120+347+36+342 = 888.
Jesus, the savior of souls, is now firmly alongside the Zodiac Killer once again. You will notice that the number 13 has been converted to one and three. This is done to transfer it into text form (to enter into the Zodiac code), exactly the same technique employed in the two previous ciphers, where the Omega, Taurus and Aries symbols were also converted into text form.
If we had left the figure 13 alone, that line would have totaled 360 (the degrees in a circle). Giving us 13 and 360 (13 punch holes). 

The next correspondence was the 'Halloween' card mailed on October 27th 1970. But this marked a deviation in the Zodiac's thinking. He was now likely trying to simplify things in an effort to push us towards Jesus- Hallelujah.
In the flap of the envelope he writes "sorry no cipher" twice, in the form of a multiplication sign. He could easily have written  "sorry no cipher" once, but evidently wanted to form the multiplication sign as an offering to our savior. If there was no cipher, then there is no code. The only 'cipher-like code' on the 'Halloween' card is the configuration of letters (not dissimilar to the "sorry no cipher" offering). The Zodiac intersected Paradice and Slaves, with four quadrants containing the words By Fire, By Gun, By Rope and By Knife. Was the word By a form of multiplication.
       

Using the path of least resistance we added up the letters in the 'cipher-like code', which totaled 37, and multiplied it by "sorry no cipher", placing it over the cross of Paradice and Slaves, as both formed a similar design. There are 24 letters in the four quadrants, giving us 37 X 24 = 888.
There were 37 letters in the 'cipher-like code' and we needed a number to multiply it by. In this case 24.
The next postcard was the 'Pines card' mailed on March 22nd 1971. If the Zodiac was simplifying matters, then this card would follow the identical technique displayed in the 'Halloween' card.
The 'Pines' card offered a set of 5 phrases.[1] 'Sierra Club'  [2] 'Sought Victim [3] 'Peek through the pines' [4] 'pass Lake Tahoe areas'  [5] 'around in the snow.'
The letters on this card would add up to exactly double the amount on the 'Halloween' card- exactly 74. 
We again needed a number to multiply it by. So let us take a punt on the figure 12 which the Zodiac supplied. 
​74 X 12 = 888 once again.  

But would the old Zodiac code resurface in one final offering on the 'Pines' card front- pushing us in both directions. 
The Zodiac drew our attention to Paul averly=chronicle.
Using the Zodiac code at the top of this page:
PAUL AVERLY = 3162 155522 = 32
CHRONICLE = 365215325 = 32
Thereby giving us PAUL AVERLY=CHRONICLE.

This completes the 888 and 444 sequence through seven cryptic Zodiac communications. But whether it is really there, or just a case of mathematical trickery and wordplay, is something only Zodiac knows.
Maybe the afterlife holds all the answers.

THE BIBLE CODE OF A KILLER

The Zodiac created four ciphers, of which only one has ever been solved and confirmed by overwhelming consensus. 
The third code is simply too short to achieve any meaningful decryption and the 'Button' letter '32 Symbol' code has only three repeating characters, making these two codes, without a key, effectively unbreakable. If we had the key however, then we would be back in business.
​It is perfectly reasonable after the solve by Donald Gene and Bettye June Harden in the August of 1969, to believe that all the remaining ciphers contain a message, after all, what would be the point of them other than a joke on Zodiac's part.
​It is my contention that the remaining three ciphers are all probably linked by religion, and Jesus Christ in particular.
The Zodiac chose a Celtic Cross style moniker, talked of "paradice" and the "afterlife," and placed crucifix style designs in his 'Halloween' and '13 Hole' postcards. You could say the Zodiac Code was the forerunner to the Da Vinci Code.
The key to the Zodiac Code is the previously discussed '13 Symbol' cipher, where the Zodiac splits the alphabet A through M to expose perfect symmetry in the third cipher. This is the template we shall use in the '13 Symbol' and '32 Symbol' ciphers, and in both instances arrive at exactly the same holy number. 
The Zodiac crosshairs can be noted in every cipher or code, so it is imperative we derive a mathematical figure for this moniker. But first we shall present the Zodiac Code that will be used on both ciphers.

The alphabet on the right has been split symmetrically into two halves. A through M was used in the Embedded Symmetry article, in which only the numbers 3, 1 and 5 were ever generated. The number 315 can be generated in several ways using the Zodiac Killer communications, but the simplest way is to take the Zodiac horoscope.
The Zodiac used what appeared to be an upside-down Aries symbol on the April 20th 1970  '13 Symbol' cipher. Many people also considered that the three circled 8's were in fact three circled Taurus symbols. But the reason the Zodiac Killer circled them, was possibly so they could be interpreted as both. Since we are dealing with the Zodiac horoscope, we will take the characters as one Aries and three Taurus symbols.

On the left is the Zodiac horoscope placed into the Zodiac Code (above).
This generates the figure 315 for the Zodiac crosshairs. 
Because we will be using Aries and Taurus in the '13 Symbol' cipher, I will explain how to arrive at the figures in brackets:
ARIES = A+R+I+E+S = 1+5+5+5+6 = 22.  
TAURUS = T+A+U+R+U+S = 7+1+6+5+6+6 =31.
ARIES =22, TAURUS = 31.

Before we move on it is important to mention the following again.
'In Christian numerology, the number 888 represents Jesus, or sometimes more specifically Christ the Redeemer. This representation may be justified either through gematria, by counting the letter values of the Greek transliteration of Jesus' name, or as an opposing value to 666, the number of the beast. Wikipedia.
In English gematria the figure for Jesus is 444'.  
If the Zodiac was creating his own bible code and referencing the rebirth of Christ using the number 8 for infinity, one would hope to find the figure 444 in the '13 Symbol' cipher shown below.  
​
Let us proceed and place the numbers alongside the relevant characters (see below). 
Notice again how the alphabetical characters only produce the figures 3, 1 and 5, as does the figure 315 representing the Zodiac crosshairs. 
The total value of the '13 Symbol' cipher is 444, representing Jesus. 

​We shall now move on to the '32 Symbol' cipher mailed just two months after the previous cipher. It contained only three repeating characters, the letter C, the letter O and the clear triangle, making it impossible to solve without a recognized key.
This led me to believe that these two ciphers were only solvable by some form of mathematical key.
Below I have used the same technique, using the Zodiac Code, representing the letters of the '32 Symbol' cipher by numbers. The Zodiac crosshairs are again attributed the 315 value and the Aries symbol the figure 22 once more. This time however, we have an Omega symbol, so we have to attribute it a figure.
OMEGA = O+M+E+G+A = 2+1+5+7+1 = 16. The six geometric shapes in the '32 Symbol' cipher cannot be attributed a name, and therefore cannot be attributed a value. They have been marked with a red X. 
You can see below, that when the numerical values are added up we arrive at the figure 444 once again.
Zodiac representing the figure 888, and both the remaining ciphers totaling 888. Whether it be 444 or 888, the reference to Jesus or Jesus Christ through the bible code of the Zodiac Killer is certainly possible. 

​The '408' cipher was divided up into three parts and mailed to the San Francisco Chronicle, Vallejo Times-Herald and San Francisco Examiner newspapers, but the final 18 characters of this cipher were unable to be decoded. Many speculated as to whether this was just filler to create three equal parts of 8 lines. Was this the rudimentary beginnings of 888, that he would carry through to his remaining ciphers and the name Zodiac itself? 

340 CIPHER- EMBEDDED SYMMETRY

This is a rehash of earlier articles concerning the 340 cipher and 13 Symbol cipher, regarding their symmetry and correlation to one another. If you are familiar with the 888 theory, then you need go no further.
The 340 cipher was the second cipher mailed on November 8th 1969- the 13 symbol cipher was the third cipher mailed on April 20th 1970, separated by just over five months. The Zodiac would refer to his 340 cipher at the beginning of the April 20th letter, stating: "This is the Zodiac speaking. By the way have you cracked the last cipher I sent you. My name is...."
This could be a simple clue leading into his new cipher, however, the author of the letter is highly unlikely to submit his real name. In addition, it is simply too short a code to be verifiable, and the Zodiac Killer must surely have known this if he had any rudimentary knowledge of code breaking. But with a clue or key affixed to the 13 symbol code, then we may have a chance.
Up to this point in time we only knew the murderer by the pseudonym Zodiac, so let us complete the introduction on the April 20th 1970 letter: "This is the Zodiac speaking. By the way have you cracked the last cipher I sent you. My name is Zodiac."  This however sounds a little flawed, so it is imperative we replace Zodiac with an alternative, something possibly embedded within the name Zodiac itself. 

​The 340 cipher has been entered into every powerful computer known to man with no solution being found, leading many people to believe it has no solution at all, and is in effect total 'gibberish.'  I don't know about the entirety of the 340 cipher, but the final twentieth line of the cipher does contain perfect symmetry in six of the final eight characters. In addition eight of the final nine characters are effectively carried forward from the 340 cipher to the 13 Symbol cipher, linking cipher two and cipher three together. In the 13 Symbol cipher he did refer to "My name is..," so we will look for his pseudonym in the 340 cipher and take this as the clue. 
We already know that six symbols on the twentieth line of the 340 cipher look very similar to his pseudonym Zodiac, but was this unintentional or deliberate. To find this out we shall look at the symmetry of both ciphers.
The 13 symbol cipher from a character standpoint is extremely organized. It starts and ends with three alphabetical characters. The three circled 8's are symmetrically placed in positions 5, 7 and 9. The Zodiac symbol and 'upside down Aries' symbol are four in from either side. Either the Zodiac just happened upon this symmetry, or he designed it for purpose.
Bearing this symmetry in mind, we will look for a symmetrical answer in both the 340 cipher and 13 Symbol cipher, and in addition symmetry between the two.
The Zodiac Killer was undoubtedly an egotist, so it wouldn't be all that surprising if he used his own pseudonym in the clue, and embedded the answer within the name Zodiac. In the following examination I will be using the identical mathematical technique on both the 340 cipher and 13 Symbol cipher, to show perfect symmetry in both instances. It was this egotism that led me to believe the clue resided in the 'near' Zodiac on the twentieth line of the 340 cipher. So using a comparison technique, I placed the proper spelling of Zodiac under the 'near' Zodiac and simply counted the numerical alphabetical difference in the columns. But first let us take a look at the 13 Symbol cipher and note the bottom two lines in the diagram below.
Because of not only the existing symmetry within this cipher, but the fact it was thirteen characters in length, began with an A and ended with an M, along with Zodiac's penchant for word games, it seemed the obvious choice to place the first 13 letters of the alphabet under the cipher. 
A to A = 0, B to E = 3, C to N = 11, F to K = 5, H to M = 5, K to N = 3, A to L = 11. 
It is achieved by staying within the alphabet and counting the numerical distance between the letters. Obviously, when we do not have two alphabetical characters there can be no difference, so a zero is attributed. You could attribute an X, it actually makes no difference to the resulting symmetry.

​Highlighted in red and green the obvious symmetry can be observed. But how likely can this be created by accident. 
By taking the three circled 8's as H's, it can still be seen that only three natural numbers are ever produced - 3, 1 and 5. 
How do we know if this is the technique that Zodiac employed? If we apply this technique to the 'near' Zodiac on the twentieth line of the 340 cipher using the correct spelling of Zodiac and it again produces perfect symmetry, then we have possibly bolstered our case. If, in addition, it produces something significant that relates to the 13 Symbol cipher, does it then become even more compelling? The most obvious choice this time is to place Zodiac underneath the six symbols on the twentieth line, like so:

Using the identical technique we used in the 13 Symbol cipher, we shall again count the numerical difference in the columns.
Z to Z = 0, O to O = 0, D to triangle = 0, I to A = 8, A to I = 8, C to K = 8.
That is three 0's and three 8's, carried forward to the 13 Symbol cipher on April 20th 1970. But that is not all.
Either side of the 'near' Zodiac on the twentieth line of the 340 cipher we have the crosshairs and an 'inverted Aries' in part.  
Both of which are situated on the 13 Symbol cipher, either side of the circled 8's (shown in the red rectangular boxes above).
This means, that effectively eight characters out of the last nine were effectively carried forward from the 340 cipher to the 13 symbol cipher. It could be argued that the last eight characters of the 340 cipher were carried forward, the plus sign (+) at the end of the 340 cipher signifying their addition to the 13 Symbol cipher.
​Zodiac is now represented by the three circled 8's. 'In Christian numerology, the number 888 represents Jesus, or sometimes more specifically Christ the Redeemer. This representation may be justified either through gematria, by counting the letter values of the Greek transliteration of Jesus' name, or as an opposing value to 666, the number of the beast.' Wikipedia. This may be important when we consider the Zodiac's tendency to speak of "paradise" and the "afterlife" in many of his communications, in particular his 408 cipher. He would also cross "paradice" and "slaves" in the form of a crucifix on the Halloween card, as well as pasting a red crucifix on the 13 Hole postcard.  
You can see in the above diagram that the letters K and M are embedded within the three 8's and therefore embedded in the name Zodiac. Were these his initials, and was he elevating himself to divine status? He certainly had the ego for it.

# There are some additional features of interest:
The 408 cipher was divided up into three sections of 8 lines and mailed to three different newspapers.
The final line of the 408 cipher contains an M and reversed K.
The final line of the 340 cipher contains an M and reversed K.
The 13 Symbol cipher contains the letter M and K.
The final character at the end of each of the three communications of the 408 cipher is either an M or reversed K.
The top line of the 32 Symbol cipher mailed on June 26th 1970 contains an M and reversed K.

The 'Halloween' card was mailed to the San Francisco Chronicle on October 27th 1970 inferring a fourteenth victim. On July 26th 1970 the Zodiac Killer mailed the 'Little List' letter claiming thirteen victims. If nurse Donna Ann Lass was a Zodiac victim, then the 'Halloween' card must surely have been referring to the disappearance and likely murder of Donna Lass from the Sahara Tahoe Hotel & Casino on September 6th 1970. But why did it take the Zodiac Killer nearly two months to send this correspondence to the San Francisco Chronicle newspaper? Was it imperative for the killer to somehow tie this possible murder into the Halloween festival - and did the depiction of skeletons, the pumpkin and the phrase "peek a boo you are doomed" provide any clue to the location of Donna Lass' body or burial site.

This by all accounts was a bold and brazen abduction at the end of the young woman's shift at approximately 1:50 am, in a seemingly predetermined crime. If this was a serial offender, such as the Zodiac Killer, then the clues may lie in previous similar unsolved crimes with overlapping traits. The following ideas will be examining this possibility, using the design of the 'Halloween' card and later 'Pines' card mailed on March 22nd 1971, also believed by some to have been crafted by the hand of the Zodiac Killer. 

The choice of a skeleton on this card may have been deliberate, bearing in mind Donna Lass was likely murdered the day of her abduction and had remained undiscovered for nearly two months at this juncture. It is also easy to understand how the card can be interpreted as a skeleton wearing a pumpkin. But what if the depiction is implying something more sinister, in that Donna Lass is buried beneath a pumpkin or pumpkins? This may seem a ridiculous observation, until we consider the second skeleton on the card inner wearing a mask of sorts. Could the killer have intended us to interpret the card differently - such as an eye patch, thereby implying the phrase 'pumpkin patch'? The clue may not be entirely literal, but effectively implying the young woman may have been buried on farmland, which may have grown pumpkins or sold farm produce. This is a real stretch, so we will go further. 
​
Randall Scott Clemons produced an interesting article linking the Zodiac Killer to various golf courses, and suggesting that he may have traveled extensively to murder in certain areas he was familiar with through his pastime. In his first contact with the newspapers on July 31st 1969 the killer stated "This is the murderer of the 2 teenagers last Christmass at Lake Herman + the girl on the 4th of July near the golf course in Vallejo". The murderer of Paul Stine on October 11th 1969 escaped into the Presidio Park adjacent to the Presidio Golf course. The Aetna Springs Golf Course, Napa, was one of the first golf courses west of the Mississippi River and built on the Aetna Springs Resort's property in 1891. It is only 11 miles as the crow flies from the Knoxville Road, bordering Lake Berryessa, the site of Zodiac's third attack on Bryan Hartnell and Cecelia Shepard.​

But more crucially, it is less than 5 miles from Pope Valley, the location where the three young women had driven through at around 3:00 pm on September 27th 1969, just before they encountered a strange man who appeared to be following them. Did he have a ball marker on him that day, which came in useful at around 6:30 pm?
​
Deana Hooper's skeletal remains were discovered on March 11th 1975 in an open field at Columbus Parkway and St. John's Mine Road, right next to the Blue Rock Springs Park Golf Course. She was last seen on July 11th 1974 at the Enlisted Men's Club on Mare Island.  Established in 1892, Mare Island Golf Club in Vallejo, California is the oldest golf course west of the Mississippi River. Originally built as a 9-hole course,  its first 30 years included sand greens and dry fairways. The course began near the former Marine Barracks and proceeded south to Lake Rodgers (built in 1876 and named after Rear Admiral Rodgers), then returned to the start. Was the killer somehow connected to the military, and an avid golfer, that inevitably made him familiar with these murder sites?

The 'Pines' card depicted an advertisement for mountain condominiums.
A newspaper article stated that: 'the site depicted on the 'Pines Card' was from an advertisement published last Sunday by several newspapers. It was an artist's rendition of houses among the trees at a Boise Cascade Company project at Incline Village, where construction has just begun on the development. While much of the Sierra area is under several feet of snow, Incline Village has only two feet on the ground. Police went to the area to determine if a search is possible'.
Many observers toyed with the idea that Donna Lass may have been buried by the punch hole in the card - but surely that would have been too simple a clue by the Zodiac Killer. In another stretch of the imagination, could the positioning of 'Sierra Club' on the tree, be designed to give the impression of a flagpole? We would then be possibly looking for a burial site east of a Sierra Club golf course - not at Incline Village - but somewhere 'past the Lake Tahoe areas'. Somewhere the killer was familiar with and had used to bury a previous victim. 

​Judith Hakari was a nurse at Sutter Hospital, who disappeared heading back to the Markston Apartments on March 7th 1970. Her body was later discovered by Ponderosa Way in Weimar, forty two miles along Interstate 80.​
'At 11:30 pm. Hakari calls her fiance to tell him she's leaving Sutter Memorial Hospital where she works as a nurse. By 1:30 in the morning, she has still not come home. Her fiance, waiting at her apartment, begins to worry. "He went out to the apartment complex parking lot and discovered her car was parked in the assigned space that she had," Links said. But Judith was nowhere to be seen. She was found one month later, strangled and bludgeoned to death. "Some hikers discovered a body in a shallow grave up in the town of Weimar, in Placer County. And during their investigation they determined that it was Judith Hakari," Links said.' Fox40.com.
​
Both Judith Hakari and Donna Lass were nurses, who disappeared after their shift end, both at night or in the early hours of darkness, and both en route back home. Is it conceivable that the murderer of Judith Hakari is also responsible for the abduction and murder of Donna Lass, and if so, did he bury or conceal her body somewhere he was familiar with and had ultimately escaped detection before - in Weimar. Or somewhere very close?

We could be looking for a location in Placer County near farm land, that may have a connection to pumpkins. There will be a Sierra Club golf course west of the location. It may also be a location that has relevance to parts of the phrases contained within the 'Halloween' card, such as "From your secret pal," "peek a boo you are doomed" and "slaves." And more importantly, somewhere close to where Judith Hakari's body was discovered.

There is such a place in Colfax, Placer County, California. It was named after Schuyler Colfax Jr, known for his opposition to slavery while serving in Congress, and was a founder of the Republican Party. In January 1865, as Speaker of the House, Colfax made the unusual choice to cast a vote for passage of the Thirteenth Amendment. Colfax is located 4.4 miles (as the crow flies) from Ponderosa Way, the burial site of Judith Hakari.

The Bierwagen's Donner Trail Fruit and Farm Market near Chicago Park, is situated only 7 miles east of the Alta Sierra Country Club and golf course. Secret Town is 7 miles from Colfax and 14 miles from Ponderosa Way.
​
The residence of Judith Hakari and the area her body was discovered, not only were situated alongside Interstate 80, but Ponderosa Way is only 2 miles or 5 minutes from Interstate 80, and the Markston Apartments only 4 miles or 8 minutes from Interstate 80.  Interstate 80 is bisected by Colfax and runs from the Markston Apartments, where Judith Hakari lived, to Truckee, ​California on the north side of Lake Tahoe. Ponderosa Way (as the crow flies) is 38 miles from the Markston Apartments and 46 miles from Truckee. Was the same killer responsible for the murder of both women, and prepared to create a preconceived buffer zone to each burial site? A familiar 'dumping ground' similar to that employed by the likes of the Green River and Gilgo Beach Killer.
​​
Finally, we have a lonely lane in the heart of 'pine country,' where you can "peek through the pines" into "Peek A Boo" lane, just 2 miles (as the crow flies) from Ponderosa Way. But would you be doomed?   

In a previous article it was shown how the Zodiac Killer began mailing his later correspondence further afield, beginning on March 13th 1971, when the Zodiac Killer mailed the 'Los Angeles' letter from Pleasanton, Alameda County. This was followed by the 1974 letters, including the 'Citizen Card', again mailed from Alameda County, along with the 'Red Phantom' letter, postmarked San Rafael, Marin County on July 8th 1974. All had Interstate 580 in common, suggesting that the Zodiac Killer may have been mailing his letters to and from particular locations, that tied in with the military bases of Alameda Naval Air Station and Naval Auxiliary Field Crows Landing - the latter of which is situated only 24 miles from the intersection of Highway 132 and Interstate 5, the area where Kathleen Johns was abducted on March 22nd 1970. The connection we were trying to formulate was a military angle, the killer's reasons for being at specific locations at particular times and murders that took place close by to certain major travel routes. The killer, if murdering on the fly, needs ease of access and egress if at all possible, especially when you have avoided near capture, as experienced on October 11th 1969. To catch up on the previous article visit  http://www.zodiacciphers.com/zodiac-news/en-route-to-san-francisco​   

The Zodiac Killer appeared to cease his murderous rampage by 1970, yet there were four murders, one abduction and a missing woman (likely murdered), all along one particular route - that of Interstate 5 and Interstate 80, which directly spans South Bird Road (the area of Kathleen Johns abduction), to the area where Donna Lass went missing from Stateline, Nevada on September 6th 1970, having finished her shift that day at the Sahara Tahoe Hotel. There were three murders in Sacramento.

Judith Hakari was a nurse at Sutter Hospital, who disappeared heading back to the Markston Apartments on March 7th 1970. Her body was later discovered by Ponderosa Way in Weimar, forty two miles away, along Interstate 80. Nancy Bennallack was murdered on October 25th 1970 in her apartment, just a stone's throw from where Judith Hakari lived, near Glendale Lane. Carol Beth Hilburn was murdered on November 14th 1970, last seen on Del Paso Boulevard and found on Ascot and 4th Street.  These two areas are bisected  by Interstate 80. Sandwiched in between these murders were the two abductions of Donna Lass and Kathleen Johns.

If we look at the relevant areas off Interstate 5 and Interstate 80, then we notice certain key features.
The site of Kathleen Johns abduction and where her vehicle was discovered burnt out, is only 1 mile or 2 minutes traveling time from Interstate 5. The residence of Judith Hakari and the area her body was discovered, not only were situated alongside Interstate 80, but Ponderosa Way is only 2 miles or 5 minutes from Interstate 80, and the Markston Apartments only 4 miles or 8 minutes from Interstate 80.  Regarding Carol Beth Hilburn, Del Paso Boulevard is only 2.2 miles or 5 minutes traveling time to Interstate 80, and Ascot and 4th Street only 3 miles or 7 minutes from Interstate 80.

Interstate 80 continues on to Lake Tahoe, near the area where Donna Lass went missing on September 6th 1970. Six and a half months after her disappearance, the Pines card was mailed to the San Francisco Chronicle, purportedly from the Zodiac Killer. The search for Donna Lass was badly affected by the inclement weather in the months after her disappearance, highlighted by Police Chief Ray Lauritzen from the outset "We don't know where we're going to begin. There's a four or five foot pack of snow out there and it's still snowing heavily". The Pines Card made reference to the snow, but in a sinister way inferred Donna Lass may be buried under it - hence the phrase 'around in the snow' being placed at ground level and pasted upside down. In a newspaper article it stated that the site depicted on the Pines Card was from an advertisement published the previous Sunday by several newspapers. It was an artist's rendition of houses among the trees at a project at Incline Village, near Clair Tappaan Lodge, Norden, California - the address of which happens to be 19940 Donner Pass Road. Whether this name and that of the missing woman is a coincidence is unknown. But again, Clair Tappaan Lodge is situated right alongside Interstate 80, only 2.3 miles or 4 minutes by car, suggesting somebody traveling this route would likely have been familiar with this area and may well, as the 'Pines Card' suggested, held clues to a burial site.

On December 27th 1974, a Christmas card was mailed to Mary Pilker, Donna Lass' sister, portraying trees covered in snow. Once opened it revealed a message that was part of the card itself  - 'Holiday Greetings and Best Wishes for a Happy New Year', followed by the handwriting "Best Wishes, St Donna & Guardian of the Pines".    

Here is the card and here is the street view in winter from Donner Pass Road, outside Clair Tappaan Lodge. 
On the 'Pines Card' mailed on March 22nd 1971, text on the card read;  [1] 'Sierra Club'  [2] 'Sought Victim 12'  [3] 'Peek through the pines'  [4] 'pass Lake Tahoe areas'  [5] 'around in the snow' (pasted upside down). 
If we were reading hidden clues from this correspondence and searching for a possible burial site, then we have to follow its directions from the last sighting  of Donna Lass at the Sahara Tahoe Hotel and Casino, and head towards the Clair Tappaan Lodge and the Sierra Club. 

California State Route 89 skirts the western shores of Lake Tahoe towards Truckee, California and passes many 'Lake Tahoe Areas' en route. It finally joins Interstate 80 only 1.5 miles or 3 minutes from Donner Memorial State Park, in memory of the ill fated Donner Party.
Again, whether this was Zodiac's intention to direct us to a 'Donner Memorial' using a play on words, is sheer speculation.
But this area and the site of Clair Tappaan Lodge would certainly lend weight to the phrase 'Peek through the pines', as the lodge is literally yards from Donner Pass Road. 

This brings us to the disappearance and ultimate murder of Phyllis O'Brien Carson on October 27th 1970 - a significant Zodiac date regarding the Halloween Card. Phyllis O'Brien Carson (32) was a young mother of four children, last seen after a night out at the Francis Truck Stop, French Camp, San Joaquin County, California. French Camp is a small community situated approximately ten minutes drive south of the town of Stockton CA and fifteen minutes north of Manteca CA. Since the construction of California State Route 120, Manteca had become a popular choice for workers from the main towns and cities, along with the Bay Area, as rising house prices forced people to search for cheaper alternatives. Interstate 5 and State Route 99 are integral commuter routes through California, with the I-5 the main highway on the west coast of America, linking to San Diego, Los Angeles and Sacramento. San Francisco lies 80 miles and a one-hour twenty minute drive due west from French Camp.

Phyllis had visited the popular bar, along with her brother and sister on October 27th 1970 - and later on during the evening placed a phone call to her home residence to check on her children, stating she was to receive a lift home from a friend. Sadly for Phyllis O'Brien Carson and her family, her journey home was never realized. She had vanished without a trace - that is until family members received the heartbreaking news just over three weeks later, on November 21st 1970, that her body had been discovered laying down an embankment near to Yettner Road, only five miles from the family residence. The cause of death and perpetrator remain unknown, but foul play was certain, as her body was partially clothed and seemingly thrown from a vehicle. However, robbery was apparently ruled out, as her belongings appeared untouched. Nobody from the bar has ever come forward to this day with a name of the mystery friend that Phyllis was supposed to have left with that night. 

Interstate 5 bisects French Camp and Yettner Road - and it can be seen here on Google Maps how close both locations are to the main thoroughfare. Both less than half a mile. Almost as though the killer in all the above circumstances is simply passing by these areas via a main highway, that he has traveled many times before - possibly as a result of his profession.

The Modesto abduction of Kathleen Johns, whether or not this has a Zodiac connection, provides the closest link, in that the perpetrator of this crime chose to subject his victim to what appeared to be an aimless drive around the countryside of Tracy, CA, after which she escaped to a nearby field. Where the abductor was ultimately heading may never be known, but Tracy CA, San Joaquin County is a mere 15 to 20 minute drive from Yettner Road and only 15 miles due west from Manteca CA. Therefore, a familiarity with the area remains plausible. This now takes us back to the military connection.

Running right by NASA Crows Landing is Interstate 5, which then intersects with Highway 132 only 24 miles north - a journey of 22 minutes by car. In fact, Interstate 5 joins Highway 132 (the route Kathleen Johns fatefully took that night) only 0.8 miles shy of where she was abducted and ultimately where her car was found burnt out, near Bird Road.

'McClellan Air Force Base (1935–2001) is a former United States Air Force base located in the North Highlands area of Sacramento County, 7 miles (11 km) northeast of Sacramento, California. NAS Fallon in Nevada was originally built in 1942 as part of a defensive network to repel a feared Japanese invasion of the west coast. It was soon taken over by the Navy for training use and has been used as such ever since with the exception of the period of 1946 to 1951, during which it was used by the Bureau of Indian Affairs. During the years prior to 1972, the base was known as Naval Auxiliary Air Station and was heavily used during the Vietnam War by various squadrons that rotated through the base before deploying to carriers headed for Vietnam.' Taken from Wikipedia. These military connections run from Patterson in Stanislaus County to the east of Lake Tahoe. NAS Fallon is located just south of Interstate 80.

If the Zodiac Killer was responsible for the Modesto abduction of Kathleen Johns and the disappearance of Donna Lass, are these observations enough to convince us that he is the responsible. These two areas span 160 miles. The question being, did the Zodiac Killer travel from the Bay Area (if he lived there) to simply commit his crimes and return - or was he likely stationed at any one of these military bases that punctuated Interstate 5 and Interstate 80. His profession may have involved him traveling between these bases, either as a member of the military, a supplier to the military or an independent contractor, but nevertheless, a profession that created perpetual mobility throughout these areas of California. Interstate 80 and Interstate 5 may have played a role with respect to certain serial killers, but was the Zodiac Killer one of them?   

Donna Ann Lass (25), born on November 3rd 1944 in Sioux Falls, South Dakota, was the youngest of eight children who spent her formative years in Beresford, attending Beresford High School and eventually graduating as a registered nurse in 1965. She worked as a private nurse prior to traveling to San Francisco and setting up residence in Balboa Street, before commencing her duties as a Staff Nurse at the Letterman General Hospital in the Presidio. However, her employment at the Letterman General Hospital was short lived, spanning February 1970 to May 1970, before she took a job at the Sahara Tahoe Hotel and Casino on June 6th 1970. She initially moved in with a couple, Larry and Ann Lowe, before renting her own apartment at 3893 Pioneer Trail at the beginning of September. Six days later she would go missing.
​
The connection of Lawrence Kane to Donna Lass, claimed by retired law enforcement officer Harvey Hines, we are familiar with. Lawrence Kane, it was claimed, lived at 217 Eddy Street at the time of the Paul Stine murder. This location is less than a quarter of a mile from the Mason and Geary intersection, the presumed pick up point of Zodiac on October 11th 1969. Donna Lass moved to Lake Tahoe in June 1970, as did Lawrence Kane, with both ending up working at the Sahara Tahoe Hotel. However, this is not about Lawrence Kane, it is about the connection between Donna Lass and the hotly disputed 'Pines' card mailed to the San Francisco Chronicle on March 22nd 1971, the first anniversary of the Modesto abduction of Kathleen Johns.
​ 
This card is regarded a hoax by many Zodiac investigators, particularly puzzling, because it states on the card in pasted lettering "Sought victim 12". This tally of likely only eleven victims and searching for a 12th, is totally out of sync with the rest of Zodiac's correspondence. He had already claimed 12 victims as far back as June 26th 1970 when the 'Button' letter was mailed to the San Francisco Chronicle, along with 13 victims, ranging to 17+ victims, by the time the 'Los Angeles' letter arrived on March 13th 1971. Then nine days later the 'Pines' card surfaces, searching for 12 victims. The problem we have, is that even a half-decent hoaxer, who knew only the bare minimum about the case, is unlikely to have bypassed at least five pieces of correspondence and the multitude of newspaper articles. This person would have to be the worst hoaxer this side of Lake Tahoe, unless of course, it was the killer and the "sought victim 12" had particular significance. The word 'sought' may be suggestive of a killer that had previously targeted Donna Lass at an earlier time.

The question is, was Donna Lass targeted specifically by somebody with a grievance, or by a male who had been rejected or "brushed off", as the Confession letter might say? She did after all go missing from her place of work.
The date and content of the 'Pines' card may indicate this very notion. If we look at the Zodiac timeline and slot this card in where it should belong, it therefore has to come after 11 victims and before 12. ​The '13 Symbol' cipher or 'My Name is' cipher was mailed on April 20th 1970 claiming 10 victims, followed by the 'Button' letter on June 26th 1970 claiming 12 victims. Assuming the Pines card was not a mistake by a forger and actually crafted by the Zodiac Killer, it is logical that its meaning must be referring to the time period between April 20th 1970 and June 26th 1970, before victim 12 was confirmed. A newspaper article after the disappearance of Donna Lass stated that "the site depicted on the 'Pines Card' was from an advertisement published last Sunday by several newspapers. It was an artist's rendition of houses among the trees at a Boise Cascade Company project at Incline Village, where construction has just begun on the development. While much of the Sierra area is under several feet of snow, Incline Village has only two feet on the ground. Police went to the area to determine if a search is possible". ​Chief Lauritzen added "There's no point to a search at this time. It's unlikely a victim would be uncovered before spring." So its clear that this particular postcard was not designed prior to September 6th 1970, but sometime in the March of 1971. 
​
Donna Lass' date of employment by the Sahara Tahoe Hotel and Casino fell in between the dates of April 20th 1970 and June 26th 1970 - she started work on June 6th 1970. The Zodiac Killer may have been targeting Donna Lass when she announced her forthcoming plans to move to South Lake Tahoe. Was he connected to the Letterman General Hospital - the direction he may have been heading after the murder of Paul Stine on October 11th 1969? Was he rejected by Donna Lass as an undesirable suitor, or was it simply time to do his 'thing'? Donna Lass, either by necessity or the lure of a better job, prepares her move to South Lake Tahoe and the Zodiac Killer's plans are thwarted.

If the murderer of Donna Lass is the Zodiac Killer (and this is by no means certain), then there is a connection between San Francisco and South Lake Tahoe. There may also be a connection between "sought victim 12" and the time between April 20th 1970 and June 26th 1970, with respect to the Donna Lass move to Nevada on June 6th 1970, to begin her job at the Sahara Tahoe Hotel. When the Zodiac Killer decided to make good on his intention to abduct and murder Donna Lass, he would eventually travel to South Lake Tahoe to finalize what he began, then mail the 'Pines' card, pasting the words "sought victim 12", possibly suggestive of a killer who had targeted the young woman several months ago when she lived in San Francisco.   

The Zodiac Killer began his series of crimes with the double murder of David Faraday and Betty Lou Jensen on December 20th 1968, followed by the Blue Rock Springs attack on July 4th 1969, killing Darlene Ferrin and seriously injuring Michael Mageau. The killer confirmed these murders with details provided in three letters he sent to the San Francisco Chronicle, San Francisco Examiner and Vallejo Times Herald on July 31st 1969. His next attack would be in the remote region of Lake Berryessa on Bryan Hartnell and Cecelia Shepard and although there appeared to be no reference to this crime in any of his subsequent correspondence, he wasted no time laying claim to the lakeside attack, writing on Bryan Hartnell's car door within minutes of the crime. His final confirmed murder was that of Paul Stine at Presidio Heights on October 11th 1969, only fourteen days after the Lake Berryessa attack and one cannot help thinking his focus had turned quickly after his third attack, straight into the planning phase of the Presidio Heights murder, after all his dramatic costume driven attack and the recollection of surviving witness Bryan Hartnell, had given him all the publicity he could have wished for. Again, after the Presidio Heights murder he wasted no time in contacting the newspapers, writing to the San Francisco Chronicle only two days later. In other words, his first letter immediate of three of the crimes, laid claim to each one of them, with the exception of Lake Berryessa, however he still laid claim to it, in the form of written communication on the car door. Therefore, although questioned as a Zodiac crime, it made perfect sense to analyze his immediate correspondence after the Modesto abduction of Kathleen Johns and see if this cryptic letter in any way suggested a link to it.
This letter contained the 13 Symbol Cipher, mailed to the San Francisco Chronicle on April 20th 1970, just one month after the Kathleen Johns incident on March 22nd 1970.  

Technically a full moon is really only full for an instant in time. As we approach a full moon it is said to be waxing and as it diminishes it is said to be waning. A Waxing Gibbous denotes 95% illumination approaching a full moon and a Waning Gibbous denotes 95% illumination as we leave the full moon, everything in between can be regarded as varying degrees of a full moon. 
Therefore in the calendar above there is one full moon phase in Aries, before the Zodiac sign of Taurus takes over on April 20th, 21st and 22nd. This may explain the 3 to 1 configuration present on the 13 Symbol Cipher. We now have seven dates of relevance, March 22nd 1970, April 19th, 20th, 21st and 22nd, July 24th 1970 and March 22nd 1971, but whether any significance can be attributed, remains questionable. 
The March 22nd 1971 Pines Card may also have strong ties to the Zodiac horoscope signs, in its very wording and ultimately provide us with a further link back to the 13 Symbol Cipher and its three circled symbols once again. SEE HERE.

It has often been speculated upon, that four of the symbols in this cipher may be interpreted as three circled Taurus symbols (shown in red) and one inverted Aries symbol (shown in blue). But how could these four symbols in any way connect to the Kathleen Johns abduction.
The following observation will not claim a solution, just a line of thought to be considered for discussion.
In this letter the Zodiac Killer claimed to have 'killed ten people to date'. Had he murdered Kathleen Johns and her infant daughter Jennifer, this total would have read 12.
Kathleen Johns was abducted on March 22nd 1970 and on the following anniversary of this crime, March 22nd 1971, the Pines Card was received at the San Francisco Chronicle, claiming to have 'Sought victim 12'.
There are four crucial dates at play here. March 22nd, detailed twice above, April 20th 1970, the mailing date of the 13 Symbol Cipher and July 24th 1970, the date of the correspondence the Zodiac Killer mailed, claiming responsibility for the abduction of Kathleen Johns. Bearing in mind the Zodiac horoscope signs, possibly present on the 13 Symbol Cipher, were the dates on the Zodiac calendar in any way relevant to these events.
Firstly April 20th, the 13 Symbol Cipher date is the beginning of Taurus on the Zodiac calendar. The abduction of Kathleen Johns on March 22nd 1970 is one day after the beginning of Aries on the Zodiac calendar. The Kathleen Johns letter on July 24th 1970 is one day after the beginning of Leo on the Zodiac calendar. Three horoscope dates, all within one day of the Zodiac Killer timeline. Four, if you include the Pines Card anniversary.       
The 13 Symbol Cipher was sent in the April of 1970 to the San Francisco Chronicle, so let us look at at the Moon phases and lunar calendar of San Francisco from the relevant time period. But before we do, it is important to note that the Zodiac Killer circled his three Taurus symbols and the symbol for a full moon, is basically a white circle.
