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.   

In the previous article we discussed the feature film Vanishing Point, 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.  

Nine days after the Los Angeles letter, another communication arrived at the San Francisco Chronicle entitled the 'Pines' card. Harvey Hines, a former detective, wrote "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 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".  

Bearing in mind the Pines card was mailed just over a week after the Los Angeles letter, I considered whether the Vanishing Point film had any connection to the Sierra Club, Clair Tappaan Lodge by Lake Tahoe - and if Donna Lass could have been buried near to the lodge? Harvey Hines speculated that the young woman may have been buried near to this location, stating "I believe she was buried near the Sierra Club" - and the Zodiac Killer was leaving us a trail of breadcrumbs in the Pines card.

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. "Kowalski picks up the Challenger, plus a load of uppers, in Colorado and bets the dealer he can get from Colorado to San Francisco in 15 hours, which underpins and gives purpose to the mad cross-country chase. Serafian originally intended to end the film in San Francisco, somewhat reversing the notion of Bullitt's iconic chase scene by having cars race up the hills of the City by the Bay, rather than down. But after a visit, he and the production team didn't sense a warm welcome there, and weren't sure they could do the stunts and chase scenes that they wanted to. So they elected to bring the chase, and thus Kowalski's life, to an end in Cisco, California, a mostly abandoned town north west of Lake Tahoe" link..

Cisco, California is 11.7 miles west of Clair Tappaan Lodge. If you "pass the Lake Tahoe areas", including the lodge, you arrive at this location. Donna Ann Lass vanished from her place of work at the Lake Tahoe casino, but does the Vanishing Point film mirror the location of where her life came to an end, or possibly her final resting place, just like the death of Kowalski. Cisco, California is in Placer County, the burial site of murder victim Judith Hakari on March 7th 1970, also a nurse: '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.

The Symbionese Liberation Army enjoyed thumbing their nose at the FBI, law enforcement, Hearst Corporation and newspapers, in a general attack on the capitalist society they believed harmed the everyday lives of the American people. Their propensity for imitating Zodiac communications, I believe, just another avenue to obfuscate the investigation into the Zodiac murders and surreptitiously irritate any law enforcement agency. I have argued they were the agents in the design of at least three (if not all) of the 1974 communications widely attributed to Zodiac. Evidence in the form of documented Symbionese Liberation Army correspondence was used to discredit the February 3rd 1974 S.L.A letter, mailed to the Hearst family through the Burlingame, California, U.S. Postal Annex on February 10th 1974. For a full list of Symbionese Liberation Army articles visit here. It has been argued they were responsible for the Exorcist letter, S.L.A letter, Badlands card, Red Phantom letter, Albany letter and Channel Nine letter. In fact, none of the 1974 letters made any reference to the Zodiac Killer whatsoever and never utilized the infamous crossed-circle symbol.

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". The envelope was addressed to Mrs Mary Pilker, 1609 South Grange, Sioux Falls, South Dakota. It was postmarked 940, either from San Mateo or Santa Clara County.

If my contention is correct, and the four purported Zodiac communications from 1974 were actually mailed by the Symbionese Liberation Army, then there is a reasonable argument to be made, that this is the fifth - and may explain the four year delay between the disappearance of Donna Lass from the Sahara Tahoe Casino and the mailing of this cryptic communication. The height of Symbionese Liberation Army activity was in 1974. 

We also have to question why this card was mailed from San Mateo or Santa Clara County to South Dakota rather than the Chronicle newspaper. It could be perceived as a sick ploy to upset the family of Donna Lass - although this could have just as easily been achieved by directing the correspondence through a newspaper outlet with greater publicity. After four years since the disappearance, one can't help thinking that the area the card was mailed to, had some significance regarding the Symbionese Liberation Army. The Symbionese Liberation Army targeted individuals in their communications, something the Zodiac Killer never did through his four confirmed canonical attacks. So let us take a look at three of the four alleged 1974 Zodiac correspondence to the San Francisco Chronicle.

Prior to the March 13th 1971 Los Angeles letter, every Zodiac communication was mailed from San Francisco. The January 29th 1974 Exorcist letter was postmarked 940 from either San Mateo County or Santa Clara County. The December 27th 1974 Mary Pilker Christmas card was postmarked 940 from either San Mateo County or Santa Clara County. William Peter Blatty, allegedly retired to a remote and rented chalet in woodland off Lake Tahoe, and wrote The Exorcist, a story about a twelve-year-old girl being possessed by a powerful demon. 

One possible author of the S.L.A letter (and possibly the Exorcist letter) was Sara Jane Olson (born Kathleen Ann Soliah on January 16, 1947). She was a member of the Symbionese Liberation Army in the 1970s. She grew up in Palmdale, California, the daughter of Norwegian-American parents, Elsie Soliah (née Engstrom) and Palmdale High School English teacher and coach Martin Soliah. Engström, Engstrøm and Engstrom are surnames of Swedish and Norwegian origin. Was she responsible for authoring the S.L.A letter on February 3rd 1974, one or two days before the kidnapping of Patricia Hearst? To examine this possibility we have to examine her background. The S.L.A letter was postmarked "U.S. Postal Service, CA 913 PM 3 FEB 1974". Kathleen Ann Soliah was brought up in Palmdale, Los Angeles County, California, often frequenting the nearby census-designated area of Agua Dulce. In fact, Agua Dulce was the commuter route from Palmdale to 1466 East 54th Street, Los Angeles -  the site of the deadly shootout between Symbionese Liberation Army members and law enforcement on May 17th 1974, resulting in the deaths of six urban militants. The Symbionese Liberation Army had its main headquarters in San Francisco and Los Angeles. Agua Dulce had a postal zip code of 91390, tying in nicely with the postmark on the February 3rd 1974 S.L.A letter. It is less than five miles from Palmdale. Kathleen Ann Soliah was brought up in Palmdale, California but was born in Fargo, North Dakota. This obviously borders the state of South Dakota (the address on the Christmas card), possibly giving us three links to Soliah through three 1974 communications. But this isn't the only link to South Dakota regarding the Symbionese Liberation Army. Something began in South Dakota in 1973 and continued through the mailing of the Mary Pilker Christmas card.  

Let us move on to the Badlands card, I have argued, was written by the Symbionese Liberation Army as an attack on the capitalist agenda and yellow journalism of the Hearst Corporation - and why Patricia Campbell Hearst was kidnapped in the first place. Here is the introduction of a two-part article outlining this concept. 

The Badlands card was postmarked Alameda County and mailed to the San Francisco Chronicle on May 8th 1974. It stated "Sirs -- I would like to expression myconsternt (crossed out) consternation concerning your poor taste + lack of sympathy for the public, as evidenced by your running of the ads for the movie "Badlands", featuring the blurb: "In 1959 most people were killing time. Kit + Holly were killing people." In light of recent events, this kind of murder-glorification can only be deplorable at best (not that glorification of violence was ever justifiable) why don't you show some concern for public sensibilities + cut the ad?  A citizen".

But why would the Symbionese Liberation Army choose this particular movie to highlight their consternation at the running of advertisements? Here is an excerpt from Wikipedia detailing the plot of the Badlands movie:

South Dakota; 1959. 15-year-old Holly Sargis is a teenage girl living in a dead-end town called Fort Dupree. She lives with her sign painter father, although their relationship has been strained since her mother died of pneumonia some years earlier. One day Holly meets a 25-year-old garbage collector named Kit Carruthers. Kit is a young, troubled greaser and Korean War veteran, who resembles James Dean, an actor Holly admires. Kit charms Holly, and she slowly falls in love with him. As Holly falls deeper in love for Kit, his violent and anti-social tendencies start to slowly reveal themselves. Holly's father disapproves of Holly and Kit's relationship, and shoots her dog as a punishment for spending time with him. Kit then comes to Holly's house and shoots her father dead. The couple fakes suicide by burning down the house and go on the run together, making their way towards the badlands of Montana.

The movie was based upon the real life events of Charles Raymond Starkweather (20) and his girlfriend Caril Ann Fugate (14). They were a pair of spree killers who embarked on a two month rampage, killing 10 people in total, including her entire family in the area of Nebraska and Wyoming back in 1958, before they were finally captured. ​Charles Raymond Starkweather was sentenced to death and executed in the electric chair at Nebraska State Penitentiary on June 25th 1959, while Caril Ann Fugate received a life sentence but was ultimately paroled after seventeen years,.in the June of 1976. Caril Ann Fugate lived in Lincoln, Nebraska, with her mother and stepfather. In 1956, at age 13, she formed a relationship with Charles Starkweather, a high school dropout five years her senior. However, the film was mentioned in the purported "Zodiac" card (not the real events), which featured an impressionable teenage girl from a dead-end town and her older greaser boyfriend, who embark on a killing spree in the South Dakota badlands. IMDB.

So, were the Symbionese Liberation Army responsible for the Mary Pilker Christmas card in the December of 1974, hinting at the Donna Lass disappearance through their connections to this area of Dakota? So far, there is only a weak connection through Kathleen Ann Soliah (possibly being the 1974 S.L.A author) and the South Dakota Badlands card. The Mary Pilker Christmas card used the almost spiritual or symbolic phrase of "Guardian of the Pines", as though somebody was protecting a region of Pine trees. So that is exactly what we will look for in the area of South Dakota, spanning the time period in question. But crucially, we must find a link to a Symbionese Liberation Army member who was effectively a "guardian of the Pines".

On November 6, 1973, in Oakland, California, two members of the SLA killed school superintendent Marcus Foster and badly wounded his deputy, Robert Blackburn, as the two men left an Oakland school board meeting. The hollow-point bullets used to kill Foster had been packed with cyanide. The SLA had condemned Foster for his plan to introduce identification cards into Oakland schools, calling him "fascist". In fact, Foster had opposed the use of identification cards in his schools, and his plan was a watered-down version of other similar proposals. On January 10, 1974, Joseph Remiro and Russell Little were arrested and charged with Foster's murder, and initially both men were convicted of murder. Both men received sentences of life imprisonment. Seven years later, on June 5, 1981, Little's conviction was overturned by the California Court of Appeal, and he was later acquitted in a retrial in Monterey County. Remiro remains incarcerated in San Quentin State Prison serving his life sentence. Wikipedia. Joseph Remiro's commitment to fighting the United States government led him to the Wounded Knee, South Dakota battleground on the Sioux reservation in April 1973. While there he assisted by running ammunition from bunker to bunker during firefights. He also became a member of Venceremos, a Maoist action oriented Bay Area organization which had a tremendous influence upon the future SLA. link.

We can now link a Symbionese Liberation Army member to South Dakota from April 1973 with a link to the word Sioux (both present on the Mary Pilker envelope). This however, is not enough on its own.  

The image on the right is seven-headed SLA hydra-like cobra symbol based on the seven principles of Kwanzaa, each head representing a principle. The Swahili words for these seven principles are: Umoja (unity), Kujichagulia (self-determination), Ujima (collective work and responsibility), Ujamaa (cooperative economics), Nia (purpose), Kuumba (creativity) and Imani (faith). The appearance of the symbol of the seven-headed cobra on SLA publications indicates that it was copied from the ancient Sri Lankan and Indian seven-headed nāga; carved stones depicting a seven-headed cobra are commonly found near the sluices of the ancient irrigation tanks in Sri Lanka and are believed to have been placed there as guardians of the water. The particular graphic of the seven-headed cobra used by the SLA may have been copied from an illustration in The Lost Continent of Mu by James Churchward. Wikipedia. Had the Symbionese Liberation Army shifted guardians of the water to guardian of the Pines?

Wounded Knee Creek is a tribunal of the White River, approximately 100 miles (160 km) long, in Oglala Lakota County, South Dakota in the United States. Its Lakota name is Čhaŋkpé Ópi Wakpála..The creek's name recalls an incident when an American sustained an injury to his knee during a fight. The creek rises in the southwestern corner of the Pine Ridge Indian Reservation, along the state line with Nebraska, and flows northwest. It borders the site of the 1890 Wounded Knee Massacre, in which the 7th US Cavalry under Colonel James W. Forsyth massacred approximately 300 Sioux, mostly women and children, many unarmed. Towns in this region include Wounded Knee and Manderson. The Wounded Knee Creek flows NNW across the reservation and joins the White south of Badlands National Park. But as already stated, the Wounded Knee incident began on February 27, 1973, when approximately 200 Oglala Lakota and followers of the American Indian Movement (AIM) seized and occupied the town of Wounded Knee, South Dakota, on the Pine Ridge Indian Reservation. The protest followed the failure of an effort of the Oglala Sioux Civil Rights Organization (OSCRO) to impeach tribal president Richard Wilson, whom they accused of corruption and abuse of opponents. Additionally, protesters criticized the United States government's failure to fulfill treaties with Native American people and demanded the reopening of treaty negotiations. Oglala and AIM activists controlled the town for 71 days while the United States Marshals Service, FBI agents, and other law enforcement agencies cordoned off the area. The activists chose the site of the 1890 Wounded Knee Massacre for its symbolic value. Wilson stayed in office and in 1974 was re-elected amid charges of intimidation, voter fraud, and other abuses. The rate of violence climbed on the reservation as conflict opened between political factions in the following three years; residents accused Wilson's private militia, Guardians of the Oglala Nation (GOONs), of much of it. More than 60 opponents of the tribal government died violently during those years, including Pedro Bissonette, director of the Oglala Sioux Civil Rights Organization (OSCRO). Wikipedia.

Leonard Peltier (born September 12, 1944) is a Native American activist and an enrolled member of the Turtle Mountain Chippewa, who is also of Lakota and Dakota descent. He is a member of the American Indian Movement (AIM). In 1977, he was convicted and sentenced to two consecutive terms of life imprisonment for first-degree murder in the shooting of two Federal Bureau of Investigation (FBI) agents during a 1975 conflict on the Pine Ridge Indian Reservation. In the early 1970s, he learned about the factional tensions at the Pine Ridge Indian Reservation in South Dakota between supporters of Richard Wilson, elected tribal chairman in 1972, and traditionalist members of the tribe. Consequently, Peltier became an official member of the American Indian Movement (AIM) in 1972. Wilson had created a private militia, known as the Guardians of the Oglala Nation (GOON), whose members were reputed to have attacked political opponents. Protests over a failed impeachment hearing of Wilson contributed to the AIM and Lakota armed takeover of Wounded Knee in February 1973, which resulted in a 71-day siege by federal forces, known as the Wounded Knee incident. In 1975, Peltier traveled to the Pine Ridge Indian Reservation as a member of AIM to try to help reduce the continuing violence among political opponents. Wikipedia.

The links are there to South Dakota, Sioux, Pines, guardians, Joseph Remiro and the Symbionese Liberation Army, but where is the connection to Donna Lass? We already have St. Donna, however, we don't have the surname Lass. Leonard Peltier is known in his native country of Great Turtle Island as Gwarth-ee-lass - "He Leads the People." Also known among his Sioux brethren as Tate Wikuwa - "Wind Chases the Sun." Also known as U.S. Prisoner #89637-132. Worldcat.org.  

Through the actions of Joseph Remiro, the author of the Mary Pilker Christmas card may have been alluding to the defense of Wounded Knee by a Symbionese Liberation Army member, from the "guardian of the Pine Ridge Indian Reservation" to the "guardian of the Pines" - and concealing lass within its obscure meaning. However, the connections made in this article are an example of the lengths we can go to in the Zodiac community to forge a link that in all likelihood doesn't exist.

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.     

Many people have attempted to understand the meaning of the December 27th 1974 Christmas card mailed to Donna Lass' sister, Mary Pilker, with the wording "Best Wishes, St Donna & Guardian of the Pines." Was it innocuous or a sinister message from the Zodiac Killer, forever connected to the disappearance of Donna Ann Lass from the Sahara Tahoe Hotel on September 6th 1970? The following is not an attempt to claim an answer to this mystery, but to throw out a few ideas regarding this subject. The title of 'Saint' is often attached to a person acknowledged as holy or virtuous and regarded in Christian faith as being in heaven after death. Therefore, the inference that can be drawn from this card, is that Donna Lass is likely dead and her spirit is somehow serving as a "guardian of the Pines", leading some to believe she is buried in a location around Lake Tahoe. Could the author of the 1974 Christmas card be referencing something in his past in the wording he chose? ​

A newspaper article stated that "the site depicted on the (March 22nd 1971) '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 the author of the 1974 Christmas card was the same individual as the 1971 'Pines' card, could he again be referring to vacation properties at a different location, where we can tie the words "Guardian", "Pines" and "Donna" together. 

On December 15th 1971, a correspondence was mailed from Scottsville, New York and addressed to Mr J Edgar Hoover, first Director of the Federal Bureau of Investigation. The communication would claim that with proper investigation it would disclose the name and identity of the infamous Zodiac Killer of California. In an article entitled 'The John Edgar Hoover Letter', a similarity in the handwriting between this communication and the 1974 letter was noted. 

​On August 1st 1973, a suspected Zodiac letter was mailed to the New York, Albany Times Union newspaper threatening to murder an employee/nurse at the local hospital during "shift change", reminiscent of Donna Lass, who disappeared near her end of shift three years earlier. Although it appears the 1974 Christmas card was mailed from Alameda County, California, could the Zodiac Killer have been living in New York from 1971 to 1974, or beyond, and occasionally commuting to the Bay Area? The 'Pines' card was mailed on March 22nd 1971, before a hiatus of nearly three years, when the 'Exorcist' letter arrived at the San Francisco Chronicle on January 29th 1974 and culminating with the Christmas card correspondence on December 27th 1974, tenuously linked to the Zodiac Killer. Can any link be forged to New York with respect to the 1974 Christmas card?

On October 18th 1969 Paul Avery ran a piece in the San Francisco Chronicle describing the Zodiac Killer as a 'latent homosexual'. Under the banner 'Zodiac-Portrait of the Killer' he stated "The killer of five who calls himself 'Zodiac' is a clumsy criminal, a liar and possibly a latent homosexual."  Had the Zodiac Killer murdered young heterosexual courting couples as a result of his own suppressed homosexual leanings? This topic was explored in the article 'Skeleton in the Closet'. Had the Zodiac Killer moved to, or near an area of New York, akin to the Castro District of San Francisco, where he could explore his repressed identity? We now need to use a bit of that 'pattern seeking animal', in order to knit "homosexuality", "Guardian", "Pines" and "Donna" into one single location.

On the right is the 1952 brochure for 'Fire Island Pines'. It states "The original brochure from the Home Guardian Company of New York for the new Fire Island community called the Pines".
​
"Fire Island Pines (often referred to as The Pines, simply Pines, or FIP) is a hamlet in the Town of Brookhaven, Suffolk County, New York, United States. It is located on Fire Island, a barrier island on the southern side of Long Island.
Fire Island Pines along with the adjoining Cherry Grove, are the areas most strongly associated with the gay community on Fire Island. The island has been referred to as America’s first gay and lesbian town and served since the 1920s and 1930s as a refuge for vacationers and others who desired the more liberal attitude the island's occupants allowed.
The Pines, which has the most expensive real estate on Fire Island, has approximately 600 houses and a 100 unit condominium complex on its square mile of location. It has two-thirds of the swimming pools on Fire Island. Its summer seasonal population is between 2,500 and 3,000." Wikipedia.

This is the original brochure from the Home Guardian Company of New York for the new Fire Island community called the Pines, supplying bungalow sites and condominiums, much like the Boise Cascade Company project at Incline Village, Lake Tahoe. 

The Zodiac Killer had taken the phrase "peek through the pines" from the Boise Cascade Company advertisement. Did his inspiration for the 1974 Christmas card have similar roots of the Home Guardian Company?

"The surveyor called it “Five Islands.”  After a hundred years came another survey.  By then the cuts had healed, giving this surveyor the impression of a beach entire; taking “Five” for a misprint he “corrected” it to “Fire.”  Why fire?  Because fires did appear, campfires of Indians (whose name for the island was “Seal” and “Raccoon”), fires of whalers rendering blubber, fires of salvagers luring ships aground, and more kindly ones as beacons warning them away, fires of runaways, survivors– perhaps even early Sierra Club Outings".  
​Pines History.   Hurricane History at Fire Island Pines.

"The last major storm in the New York metropolitan area was in June 1972, when Hurricane Agnes tore for 10 days along the Eastern Seaboard". New York Times. 
Was the Zodiac Killer invoking the spirit of Saint Donna from the afterlife as a Guardian of the Fire Island Pines, recalling memories from his formative years? Donna Lass disappeared on September 6th 1970. Hurricane Donna appeared and dissipated between August 29th and September 13th 1960, ten years earlier. 

By coalescing various stories of homosexuality, Fire Island Pines in New York, the Home Guardian Company and Hurricane Donna, a perceived link can be forged back to the 1974 Mary Pilker Christmas card. But it's just a work of fiction like so many Zodiac claims on the internet.

This correspondence dated December 15th 1971 was mailed from Scottsville, New York and addressed to Mr J Edgar Hoover, first Director of the Federal Bureau of Investigation.
​In respect to the Zodiac timeline, it was sent 15 months after the disappearance of Donna Lass from Stateline, Nevada on September 6th 1970.
The communication claims to have evidence that with proper investigation would disclose the name and identity of the infamous 'Zodiac Killer of California.' 
The author of this letter would receive a reply dated December 23rd 1971, informing him that the matter was not within the investigative jurisdiction of the FBI and he should advise the San Francisco, California Police Department of any information which pertains to the Zodiac Killer. Signed by Director, John Edgar Hoover. 
The identity or signature of this individual is redacted, with a return address of some description- therefore determining its sincerity or otherwise is difficult to determine. One would like to think this was an extremely concerned citizen or somebody from an official agency, frustrated enough to mail a letter to the FBI offices (handwritten letter below). 

Tracers wrote this on the Zodiac Killer Tapatalk forum: "I did find this old reference to a letter: In a letter from J.Edgar Hoover dated 11/30/70 to Senator Karl E. Mundt concerning his interest in finding Donna A. Lass, he says, "In an effort to be of assistance, a search of our Identification Division files was conducted but I regret to tell you no indication of the whereabouts was disclosed. A missing person notice was previously placed in file in behalf of Senator George McGovern. In view of your interest I am having a notification added to the effect that any information we may receive will also be forwarded to you. We do not, of course, have the authority to conduct an active investigation in the absence of a violation of a federal statute within our jurisdiction."
​
Senator George Stanley McGovern was a U.S. Representative and U.S. Senator born in Avon, South Dakota, approximately 100 miles from Sioux Falls, South Dakota, which may reflect his interest in the case. 
 
Another communication in the form of a Christmas card was mailed to the sister of Donna Lass, Mary Pilker, in Sioux Falls, South Dakota on December 27th 1974. The Christmas card read 'Holiday Greetings and Best Wishes for a Happy New Year', followed by the handwriting "Best Wishes, St Donna & Guardian of the Pines." 
It is unknown whether this card had sinister connotations in respect to where Donna Lass may be buried (somewhere in between the pines), or whether it is just misguided support. There are, however, some similarities in the handwriting of the John Edgar Hoover letter and the Christmas card mailed to Mary Pilker (shown below).
Handwriting comparisons in the Zodiac case are the topic of much debate, as they are extremely subjective, and should always be used in conjunction with other evidence. 

John Edgar Hoover (January 1, 1895 – May 2, 1972) was an American detective and the first Director of the Federal Bureau of Investigation (FBI) of the United States. He was appointed as the director of the Bureau of Investigation — the FBI's predecessor — in 1924 and was instrumental in founding the FBI in 1935, where he remained director until his death in 1972 at the age of 77. Hoover has been credited with building the FBI into a larger crime-fighting agency than it was at its inception and with instituting a number of modernizations to police technology, such as a centralized fingerprint file and forensic laboratories.

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?   

This is a continuation from a previous article, but relevant in regards to the History Channel docudrama about to air on December 12th 2017. Undoubtedly they will continue to pursue suspect Lawrence Kane and attempt to provide a credible link between Lake Tahoe and San Francisco, which according to Detective Harvey Hines, Lawrence Kane had. He purportedly lived at 217 Eddy Street, San Francisco during the Paul Stine murder and worked for Alan Dorfman selling Arizona real estate at the Sahara Tahoe Hotel and Casino, the same hotel Donna Lass was employed. The likelihood of Lawrence Kane being the Zodiac Killer is down to opinion, however, as previously suggested, the link between Donna Lass, Lake Tahoe, San Francisco and the Zodiac Killer could be a very real one. A link inadvertently or otherwise, left by the killer when designing his 'Pines' card, mailed on March 22nd 1971.         

Many observers believe the 'Pines' card was crafted by a hoaxer, on account of the fact 'Victim 12' had already been claimed by the Zodiac Killer on June 26th 1970 when he mailed the 'Button' letter to the San Francisco Chronicle.
On the contrary, this could go a long way to actually validating this correspondence. Bearing in mind the make-up of the 'Pines' card, it is extremely likely it is referring to the disappearance of Donna Lass. But in order for its author to have deliberately chosen the phrase 'Sought Victim 12' in reference to Donna Lass, we could assume he knew her previous employment and movements in the preceding few months, or just made a lucky guess when choosing this particular phrase.
Would a hoaxer, having gone to all the effort of pasting up a card, then have made the basic error of getting the victim total incorrect. One could argue that the author of this card knew Donna Lass, knew that she had previously worked at the Letterman General Hospital and knew exactly when she had moved to South Lake Tahoe. 
Donna Lass left her job at the Letterman General Hospital and moved to South Lake Tahoe on June 6th 1970. Had he targeted Donna Lass before her move to the Sahara Tahoe Hotel? If so, then 'Sought Victim 12,' in its use of the past tense, could simply be implying that he had intended Donna Lass as a target before she moved from San Francisco.
Harvey Hines stated in his 120 page report "Now we have the Zodiac running into the Presidio in the direction of Letterman General Hospital. The very place that Donna Lass worked. Also, in looking at the area map, I found that Lass lived six blocks south in the 4000 block of Balboa. That meant the Zodiac Killer started his ride near where Kane lived and ended it several blocks away where Donna Lass lived and worked.
During the time she worked in San Francisco she lived at 4122 Balboa Street with a roommate named Carol Emerich. Emerich was also a nurse. According to the employment records, Lass was working a late night shift in October of 1969 when the San Francisco cab driver, Paul Stine, was killed by the Zodiac." 
If the killer knew Donna Lass, or indeed was familiar with the Presidio Park and Letterman General Hospital, then it is not beyond the realms of possibility he likely was familiar with this area and the advantages it provided as an escape route after the murder of Paul Stine on October 11th 1969.       

If the killer knew, worked with, or was familiar with Donna Lass during the short period she worked at the Letterman General Hospital, then clearly he may have sought her as victim 12 during this period.
The Zodiac mailed the '13 Symbol' cipher on April 20th 1970 claiming 10 victims. On June 26th 1970 he was claiming 12 victims in the 'Button' letter. Therefore, he must have 'Sought Victim 12' between these two dates. The window of opportunity narrows when we consider that Donna Lass left for South Lake Tahoe on June 6th 1970. If the Zodiac Killer  targeted Donna Lass while she worked and lived in San Francisco, it likely fell between April 20th 1970 and June 6th 1970. A window of just 46 days. Is this something a casual hoaxer would be aware of.
Unless the employment records and movements of Donna Lass between these dates had been reported in the newspapers, was the choice of the 'Sought Victim 12' phrase just a lucky guess on behalf of the hoaxer, and just happened to fall correctly between these dates. Did the author of the 'Pines' card do his research, or was Donna Lass specifically targeted by the Zodiac Killer, who moved or traveled to South Lake Tahoe with the sole purpose of completing his 'mission,' and the wording on the 'Pines' card was anything but a mistake. 
It may possibly dispel the preconception that the Zodiac Killer only targeted strangers, as has been alluded to in the case of Darlene Ferrin, murdered on July 4th 1969. Maybe the Zodiac Killer didn't care who he killed. 

In several articles we have explored the concept of geographical profiling to narrow down the search area for the likely residence of the Zodiac Killer, using timelines and his own words in an effort to identify the elusive murderer. A forum member of Zodiac Killer Site with the moniker 'Seagull' has been invaluable in this quest, mailing me names and addresses around the Springs Road and Tuolumne Street payphone in Vallejo in 1969. By cross checking these to previous residency in Riverside and other locations using ancestry records, a common thread is hoped to be unearthed. The problem is, it may take months or even years to manually trawl through a sample area radius of just 0.5 miles around the payphone. 
Another common thread that has been explored, is a possible link between Donna Lass and the Zodiac Killer. According to former police officer Harvey Hines "During the time she worked in San Francisco she lived at 4122 Balboa Street with a roommate named Carol Emerich. Emerich was also a nurse. According to the employment records, Lass was working a late night shift in October of 1969 when the San Francisco cab driver, Paul Stine, was killed by the Zodiac."
This, bearing in mind the disappearance and likely murder of Donna Lass only eleven months later, along with the alleged Zodiac 'Pines' card mailed on March 22nd 1971, it is something not to be overlooked. It may be coincidence, but the 'Pines' card does reveal an interesting feature, long believed to be from the hands of a hoaxer because of the victim count not marrying up with known Zodiac correspondence. However, it does in fact fit perfectly into the Zodiac timeline.         

'Lemonboy', a contributor to this site triggered this article, when he stated "What if Donna lass saw Zodiac as he was walking away from the Stine murder? After that he targets her thinking she might have recognized him. The fact she lived so close to the crime scene seems more than coincidence."
But what if the Zodiac moved in the circle of Donna Lass, knew the young nurse, or even worked alongside her. His confidence in these surroundings was evident after the murder of Paul Stine in Presidio Heights on October 11th 1969, apparent by his detailed account of events in the November 9th 1969 'Bus Bomb' letter. He may have lived in the Vallejo area and worked in San Francisco, hence the copious mailings to the San Francisco Chronicle newspaper. If we could tie this person to Donna Lass through San Francisco and South Lake Tahoe, and possibly Cheri Jo Bates at Riverside, we may inch a little closer. The 'Pines' card may be suspect Zodiac material, but the wording on the postcard does leave a subtle hint that a connection may exist.
It all lies in the wording "Sought Victim 12", considered by some an error on behalf of its sender. But if we examine the victim count of the Zodiac Killer, the past participle of seek, indicated the killer may have been targeting Donna Lass during her residency in San Francisco some four months earlier.
"Sought Victim 12" suggested that the Zodiac Killer at some point in his recent history had trailed victim 12. Bearing in mind the 'Pines' card was supposedly referencing the disappearance and murder of Donna Lass on September 6th 1970, then it isn't a giant leap of faith to believe that the murderer was searching for victim 12 relative to his timeline and the young nurse.
On April 20th 1970 the Zodiac Killer mailed the '13 Symbol' cipher claiming 10 victims. On June 26th 1970 the killer mailed the 'Button' letter and Phillips 66 map claiming 12 victims. His search for victim 12 was clearly over, according to him, therefore it couldn't have been Donna Lass, who was abducted just over two months later. However, she may have been the original target. If she had been earmarked as victim 12, as hinted by the 'Pines' card, his plans were clearly thwarted or sidelined.​      

Before Zodiac could "seek victim 12" though, he had to secure victim 11, which he wasn't claiming when the 'Dragon' card landed at the offices of the San Francisco Chronicle on April 28th 1970. Donna Lass left her job at the Letterman General Hospital and moved to South Lake Tahoe on June 6th 1970 to begin her new post at the Sahara Tahoe Hotel and Casino. If he had targeted Donna Lass in San Francisco, it would likely have fell somewhere between the dates of April 28th 1970 and June 6th 1970, but was ultimately denied to him by circumstances unknown or her move away from the Bay Area. Even if Zodiac had claimed victim 11 as early as the end of April, then we could be looking for a man who either worked with the young nurse during the month of May, was in her near circle, or had a romantic or unhealthy interest in Donna Lass during this short timeframe.
Friends and colleagues of Donna Lass included Carol Emerich and Jo Anne Goettsche, the latter of which visited her around the time she disappeared, and it is these friends, or persons close to them, that may hold the key to the identity of the Zodiac Killer during that crucial month in 1970. When the killer mailed the 'Pines' card on March 22nd 1971, either by accident or design, his mask of anonymity may have slipped even further upon pasting the words "Sought Victim 12," and place him a lot closer to Donna Lass than we care to imagine.   

The first three crimes of Lake Herman Road, Blue Rock Springs Park and Lake Berryessa were committed in situ, in that the Zodiac Killer attacked the couples where he discovered them. The Zodiac at Presidio Heights entered the taxicab of Paul Stine in the bustling theater district of San Francisco and murdered him at Washington and Cherry, although Paul Stine effectively remained in situ, within the taxicab throughout. The three crimes that have widely been attributed to Zodiac, are the Riverside murder of Cheri Jo Bates, the Modesto abduction of Kathleen Johns and the disappearance of Donna Lass from the Sahara Tahoe Casino, all of which were followed by alleged communications from the Zodiac Killer. These three crimes had one thing in common, the perpetrator used a ruse, to lure the women into his vehicle and remove them from the first point of contact. Cheri Jo Bates' car distributor was tampered with, followed by the promise of a lift home, to lure the young woman into his vehicle. Kathleen Johns, again would fall prey to the same tactic, her wheel was tampered with, followed by the promise of a lift to a service station. Donna Lass was lured away from her place of work, by a false medical emergency, to again draw the nurse toward his vehicle. Three crimes, involving three young women, and in all instances similar tactics were employed, followed by a correspondence claiming the crime. Here though, it is the Donna Lass abduction we shall concentrate on.
In the aftermath of the disappearance, the search for Donna Lass would be badly affected by the inclement weather in the coming months, highlighted by Police Chief Ray Lauritzen in the newspapers 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. There's no point to a search at this time. It's unlikely a victim would be uncovered before spring."  

It is far from certain the perpetrator of this crime knew Donna Lass, but the following will explore reasons why this may be the case.  
Similar to the second and third crimes by the Zodiac Killer, the disappearance of Donna Lass was again followed by a phone call from the supposed perpetrator. But unlike Blue Rock Springs Park and Lake Berryessa, this phone call didn't brag about his crime, it claimed Donna Lass had been 'called away' or 'called out of town' due to a family illness, all of which was subsequently proved to be false. The caller was seemingly trying to give the impression nothing sinister had happened, suggesting the act of the phone call was simply to 'buy time'. If the abductor was affording himself some extra breathing space, then the real possibility he was local to the area or known to Donna Lass is a credible argument, and he was either holding Donna Lass at this juncture, needed time to dispose of her body, or possibly needed to remove incriminating evidence from his home or vehicle before the police came knocking. This may have suggested that the responsible moved in the circle of Donna Lass, such as friends and work colleagues, who are inevitably the first people to be questioned in most police investigations. 
The nature of the call was also suggestive of a perpetrator who knew Donna Lass. A friend or work colleague through conversation or private details, would be privy to information about her family, and the fact they lived in Sioux Falls, South Dakota, 1,555 miles away. A phone call in this instance, using a family illness as a ruse, would be of the utmost benefit to the caller, possibly 'buying' the perpetrator plenty of time. The caller it would seem, knew her family did not reside in South Lake Tahoe or nearby, because this would have made the call ineffectual.
Two phone calls were laid, one to her employer and one to her landlord. The first would obviously explain her absence from work after the Labor Day weekend, the second would possibly allay the concerns of her landlord over rent collection. He may have known Donna Lass, but would unlikely have known the exact date her payments were due. The fact he called her landlord at all, is indicative of somebody who was familiar with Donna Lass, unlikely to be known by a random killer or abductor, who just turned up at the Sahara Tahoe Hotel that morning. If the perpetrator was the Zodiac Killer, then his close ties to Donna Lass could be of crucial importance, bearing in mind the widely held belief he was unknown to his victims in the first four confirmed attacks in the Bay Area. If the Zodiac Killer was also known to Cheri Jo Bates, due to the specific targeting of her Volkswagen Beetle, then Riverside and South Lake Tahoe may be more closely linked than ever imagined.  

​Donna Lass had recently moved into the Monte Verdi apartments on 3893 Pioneer Trail Road, located just a three minute drive from the Sahara Tahoe Hotel. When she first arrived in South Lake Tahoe in June she stayed with Ann and Larry Lowe at 4054 US Highway 50, and was just finding her feet in the new residence when she went missing. Although her 1968 Chevrolet Camaro convertible was discovered outside the Monte Verdi apartment complex in its usual parking spot, it is believed she had not driven it to work on the evening of her disappearance, having walked to work from this previous residence, which was a short walking distance to the Sahara Tahoe Hotel of approximately 8-10 minutes. She had made plans to meet up with her friend Jo Anne Goettsche, intending to travel back to the Monte Verdi Apartments in her vehicle, once her shift at the casino had finished.
The fact she was targeted immediately on her shift change at around 1.50 am is also telling. Had a nurse just vanished from the start or middle of her shift, this would obviously have raised a red flag with the Sahara Tahoe Casino, negating the intention of the abductor, and most certainly rendering the phone call unnecessary and highly suspicious. She had already changed from her nurses uniform into her civilian clothes, as her shift was due to end at 2.00 am, something the perpetrator likely knew.
The last person apparently to see Donna Lass before her disappearance was a Joan Bentley from San Francisco, who stated that Donna appeared in good spirits at approximately 1.40 am. The last entry on her log according to her sister, Mary Pilker, was "patient complains of", before the pen trailed off the page. This pen mark is unlikely to have been created by her being physically manhandled from the casino, as it was extremely busy during the Labor Day weekend. More likely, is that somebody approached her nurses station and asked for medical assistance in the car park. Donna Lass may have been writing in her nurses log, when she had her arm tugged in a gesture of 'please help,' or had been in the middle of writing, when she abruptly rushed off to aid the concerned citizen. Either way, her pen trailed down the page. 

The person who made the phone call was also likely aware Donna Lass had not traveled to work that evening in her 1968 Chevrolet Camaro convertible. Had he contacted the Sahara Tahoe Hotel explaining the family illness, and that she had been called 'out of town', then this would have been negated, had her employer or work colleagues noticed her vehicle sitting idle in the car park over the next few days. A vehicle she would likely have used for her trip to South Dakota.
​Was the perpetrator aware of her plans to meet Jo Anne Goettsche at around 2.00 am inside the casino, so acted just before the end of her shift. The subsequent phone call may then have served an extra purpose of allaying the worries of Jo Anne Goettsche, had she informed the casino of her concerns or contacted the police. If the perpetrator knew of Donna Lass' arrangement with her friend, he may very well have spoken to her in the preceding days, further cementing the idea he was known to the young woman.
Six and a half months after her disappearance, the 'Pines' postcard was mailed by the Zodiac Killer or an impostor to the San Francisco Chronicle on March 22nd 1971. But why did the likely killer of Donna Lass wait this long to mail the communication. Did his closeness to Donna Lass play any part?

With little progress in the Zodiac case, often we have to return to what we already know but examine it in more depth. The search for the Zodiac Killer has become wider as the years have passed, with ever more suspects being introduced into the fold, effectively diluting the identity of the real murderer. The bigger the haystack becomes, the harder the needle is to find.
One, if not the best clue in the Zodiac case, is the phone call he made from the intersection of Springs and Tuolumne at 12.40 am, on July 5th 1969, approximately 40 minutes after the attack at Blue Rock Springs Park, particularly in light of a journey that should have taken little more than 10 minutes. What did he do during this time period. We cannot rule out that he just sat in his vehicle for the entire duration, but if the killer lived nearby, then separating himself from the weapon and any blooded clothing, before making a risky phone call, appeared to be the sensible option. It has already been surmised that the killer may be local to the area, due to the fact he seemed aware that Blue Rock Springs Park and Lake Herman Road were a good place to target couples.
If the Zodiac Killer had lived in San Francisco, then he could have made this phone call anywhere en route back to his residence. There would appear little reason to sit closer to the crime scene than separate yourself from it, especially loaded down with incriminating evidence. The journey time back to San Francisco is approximately 40 minutes, with innumerable payphones on the way, thereby negating the logic of remaining in the danger zone, unless of course you lived in Vallejo and were determined to make a call to police no matter.    

Kim Rossmo, who pioneered the science of geographical profiling made an important observation that the killer exhibited target selection at Presidio Heights, as opposed to his first three crimes, where the location was the overriding consideration. If we believe the Zodiac Killer to be a resident of Vallejo or Benicia and less familiar with the San Francisco area, then control would be the order of the day and his 'search attempts' in alien surroundings are less certain. He could not afford to travel around looking for victims without designated prime locations and expect to escape with any surety, thereby he targeted the victim first and took him to a predetermined location, as opposed to the location being the prime requisite. In the Lake Herman Road and Blue Rock Springs attacks, he frequented known locations to find a victim, whereas in San Francisco he searched for a victim and took him to a location. Kim Rossmo states that 'criminals who travel longer distances to offend are less likely to use uncertain target selection techniques'.
The Zodiac Killer knew Lake Herman Road and Blue Rock Springs Park were secluded locations and knew that by cruising between these two areas he would eventually find his moment to strike, shrouded by the darkness and limited traffic. Using the software Rigel, Kim Rossmo entered various details in the Zodiac case, some of which were the murder locations, travel routes and phone calls and came up with some key areas of interest. These areas were [1] southeastern Napa County, including American Canyon and north Vallejo. [2] eastern Solano County, including east and north Vallejo, Mare Island and Benicia. [3] northern Contra Costa County, just south of the Carquinez Strait, including Crockett.
All of these areas are viable destinations to reach from Blue Rock Springs Park and back to the Springs and Tuolumne intersection in 40 minutes to make the phone call to police. This is great, but we need to narrow the field of view further and begin with the most likely first, before extending outward.     

In a recent re-examination of the Lake Herman Road murders, it was possible to open up the timeline of James Owen and Stella Borges to 12 minutes, to enable the Zodiac Killer to head to Vallejo after exiting the turnout and pass by the Borges Ranch before she entered Lake Herman Road in her vehicle. Michael Mageau stated the killer exited the Blue Rock Springs parking lot and headed in the direction of Ascot Parkway, Tennessee Street and Springs Road, so we could have the Zodiac approaching the same exit of Columbus Parkway on both occasions, heading in the direction of central Vallejo. However, with the many inconsistencies in Michael Mageau's testimony, we cannot be certain which direction the Zodiac traveled after leaving the parking lot.   
We know​ that killers employ a 'buffer zone' from their residence and we know that with increased confidence, a serial killer will move from their comfort zone further afield. Often though, their initial crimes start closer to home. This is why the Lake Herman Road and Blue Rock Springs Park crimes, separated by only 3.9 miles, are of paramount importance.
Additionally both attacks fell on a Friday, which for somebody working a normal Monday to Friday, 9 to 5 job, would explain the lack of 'adventure', that was otherwise displayed at the Lake Berryessa and Presidio Heights attacks, which both fell on a Saturday. This is referred to as the 'least effort principle'.
There is one particular area of interest, that of northern Vallejo, we can examine for all the right reasons and also examine for all the wrong reasons.​        

The area of interest is denoted by the red circle in the diagram. The blue circle is the Springs and Tuolumne payphone.
This area of interest is 4.7 miles from Blue Rock Springs Park (10 minutes). This area is 4.1 miles from the payphone (10 minutes). The times are approximated based on the route. A murderer leaving Blue Rock Springs at 12.04 am at the latest, with 15 minutes to hide the weapon and clothes at home, and ready himself before returning to the payphone, would arrive to make the phone call at 12.39 am.
This area of interest is also in a direct line south from the 1231 Main Street, Napa payphone, only 12 miles away. It is situated 9 miles from Lake Herman Road.
In each case a reasonable 'buffer zone' is employed from the crime scene at Lake Herman Road and Blue Rock Springs, and from both payphones, while still allowing the total journey time of 36-40 minutes to be achieved after the Blue Rock Springs crime.
But in all cases the 'buffer zone' is not too large either, it is a delicate balance.
Now we will focus on this area of interest for all the wrong reasons and the following must be taken with a huge pinch of salt.
Donna Ann Lass disappeared from the Sahara Tahoe Hotel and Casino on September 6th 1970, and was presumably highlighted by the Zodiac Killer in the March 22nd 1971 'Pines' card. The card itself indicated a location, thought to be the burial site of Donna Lass, but it was vague in nature, supplying what appeared to be directional markers. The 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). 
Two notable Sierra Club properties were identified. In a newspaper article it 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 project at Incline Village', located at 895 Tanager Street, Nevada. The other was Clair Tappaan Lodge at 19940 Donner Pass Rd, Norden, highlighted as a potential burial site and investigated by police officer Harvey Hines. An excavation of the site was performed but no body was unearthed. It has been stated that a pair of sunglasses, that may have belonged to Donna Lass were found, but this cannot be verified. The directions on the 'Pines' card, if from the Sahara Tahoe Hotel, seem to indicate that we have to pass some 'lake tahoe areas'. Traveling on the lake's western shore, along California State Route 89, brings us out by Truckee, only 2 miles from the Donner Memorial State Park, a few miles east of Clair Tappaan Lodge.
Here is an overhead view of Clair Tappaan Lodge on Google maps. Now let us drop to the roadside and 'peek through the pines' at Clair Tappaan Lodge.
Whether the Zodiac Killer was using a play on words, possibly bringing us out by the Donner Memorial State Park and suggesting she could be found in this area, only he knows. Or was his play on words suggestive of somewhere entirely different.  
As stated above, Clair Tappaan Lodge is situated alongside Donner Pass Road, but are we in the wrong place, and does the clue point towards a totally different area, somewhere we are much more familiar with. Somewhere only 4.7 miles from Blue Rock Springs Park.
