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, when 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, likely 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 to 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 broadened 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 slightly less 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 so close to the police station, 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 or lone individuals in the night.

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, and so 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 in 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 good news, but we need to narrow the field of view even 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 often 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 (northern Vallejo), that 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 on the left. 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 and a delicate balancing act that the killer may have factored into the equation.

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, although 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, seems to indicate that we have to pass some 'lake tahoe areas', traveling on the lake's western shore, along California State Route 89, which brings us out by Truckee, only 2 miles from the Donner Memorial State Park, and 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. Probably not.

In a recent article we covered the disappearance of two casino workers from South Lake Tahoe in 1982. Julie Schossow (25) and Marilyn Putt (27) were found murdered several months later. Both victims worked as blackjack dealers at Harrah's Lake Tahoe Casino and were last seen leaving the Rendevouz Bar at Harrah's around midnight. This casino is only 359 meters from the Sahara Tahoe Hotel and Casino.

Less than seven years after the abduction and likely murder of Donna Lass (25) from the Sahara Casino on September 6th 1970 at around 1:45 am, another woman was abducted from the same location and later found murdered.

Brynn Rainey (27), who resided on Emerald Bay Road, was early for her 2:00 am graveyard shift as a Keno girl at the Sahara Casino on July 24th 1977. She popped into a local bar, the Bitter Creek Saloon, just prior to her shift. The bar was situated near the corner of Sandy Way and Takela Drive in South Lake Tahoe, only two miles from her workplace. The bartender remembered her that night. Unfortunately she was never seen alive again. Her body was discovered the following month in a shadow grave on a South Lake Tahoe horse riding area, referred to as the Stateline Stables. Her cause of death has been classified as undetermined. It is likely she was abducted somewhere between the Bitter Creek Saloon and the Sahara Tahoe Casino. Subsequent to this article there have been further developments in the case - see comments.

The Pines Card, often questioned on its authorship, was mailed to the San Francisco Chronicle on March 22nd 1971. Was this a Zodiac correspondence offering subtle hints to the disappearance of Donna Lass (25) from the Sahara Tahoe Hotel and Casino on September 6th 1970. If we traveled the 'lake tahoe areas' on the western shore of Lake Tahoe, we would arrive at Donna Pass and the Donner Memorial State Park on its northern edge, by Truckee, California. Could this be the final resting place of Donna Lass, buried 'in the snow'?

Two years earlier, Wanda Gail Loe (26), similar in age to Donna Lass, disappeared from the Lake Tahoe region on July 27th 1968, five months prior to the Lake Herman Road murders. She worked at the Sunnyside Resort, 1850 West Lake Boulevard in Placer County. The resort is 30 miles northwest of the Sahara Tahoe Hotel, now the Hard Rock Hotel and Casino where Donna Lass was last seen. ​Her boyfriend Dennis Finn allegedly made a drunken confession to the crime according to his cousin, however, ill feeling between the pair has cast huge doubt on his claims and no evidence exists linking Dennis Finn to the crime. Later arrested and jailed for an unrelated crime, he committed suicide in 1992.

Were the disappearances of Donna Lass and Wanda Loe connected in any way - and if so - how relevant is the Zodiac Killer or Pines Card to either investigation? The disappearances were two years apart, their ages were similar and they worked on the fringes of Lake Tahoe only 30 miles apart. An officer involved in the Wanda Loe case, Sergeant Perea, believed she may be buried in the Carpenter Valley area near Truckee. Carpenter Valley Road is a mere four miles from Donner Lake and Donner Pass Road.  

The following is not meant to indicate any Zodiac connection, but its locality in relation to the Donna Lass case is worthy of mention.

Approximately eleven years after the disappearance of Donna Lass, on January 12th 1982, two young women, Julie Schossow (25) and Marilyn Putt (27)  disappeared from South Lake Tahoe. Their bodies were recovered several months later.
​On June 6th 1982 Marilyn Putt's body was found in the South Fork of the American River, one mile west of Chili Bar. The police press release stated “Her body had been weighted down with chains and binding material and the cause of death appears to be ligature strangulation, with the time of death being estimated at six to eight weeks prior to her body being found". Julie Schossow was discovered only a short distance away on July 9th 1982. The women had been bound and strangled with a ligature. Both victims worked as blackjack dealers at Harrah's Lake Tahoe Casino and were last seen leaving the Rendevouz Bar at Harrah's around midnight. This casino is only 359 meters from the Sahara Tahoe Hotel and Casino, where Donna Lass had worked in 1970. Reports circled about a possible interaction with some men, indicating that the women may have traveled with them to the Bay Area - although this is unsubstantiated.

There have remained questions over the authenticity of the '13 Hole' postcard mailed on October 5th 1970, particularly in light of the author claiming 13 victims for a second time. However, this may be the very reason the postcard is genuine Zodiac material. The 'Little List' letter claiming 13 victims, mailed by the Zodiac on July 26th 1970, was withheld from publication and not released until the San Francisco Chronicle released an article on October 12th 1970. So the Zodiac Killer by October 5th 1970 was either under the impression the 'Little List' letter was being withheld or had gone astray, hence a further communication reiterating 13 victims. There is something more important about this postcard that has yet to be fully explained - the reasoning behind the 'Fk' abbreviation, believed by some to be an expletive - but the answer may be much closer to home, bearing hallmarks of the Cheri Jo Bates murder in Riverside four years earlier.    

The Zodiac Killer has been argued to be responsible for the abduction and possible murder of Donna Ann Lass from outside the Sahara Tahoe Hotel and Casino on September 6th 1970. The 13 Hole Postcard was mailed twenty nine days later - so wouldn't it make more sense for this postcard to be somehow related, as the '13 Symbol' cipher correspondence mailed on April 20th 1970 should be related to the Kathleen Johns abduction on March 22nd 1970 in line with his earlier crimes and correspondence. In both instances a woman was seized against her will, and in both instances the following communication implied money. "I am mildly cerous as to how much money you have on my head now," and "There are reports city police pig cops are closeing in on me. Fk I'm crackproof. What is the price tag now?"

The Zodiac sent three coded segments in three letters on July 31st 1969 to the San Francisco Examiner, San Francisco Chronicle and Vallejo Times-Herald giving details of the first two crimes to police. The Zodiac Killer seemingly though still had a lot to prove to Police Chief Jack E. Stiltz, who was less than satisfied that the letter writer and killer were one and the same. On Saturday August 2nd 1969 in the San Francisco Chronicle, he requested the writer send a second letter "with more facts to prove it". Another Zodiac article featured the following day on Sunday August 3rd 1969 in the San Francisco Examiner. Jack E Stiltz was "still not convinced the letters and codes were written by the actual killer". The police chief "urged the writer to send more letters, with more facts to prove his connections to the crimes". The Zodiac responded immediately, detailing the Lake Herman Road and Blue Rock Springs attacks with greater clarity. He did exactly the same thing in the 'Bus Bomb' letter mailed on November 9th 1969, outlining his excursion into Presidio Park when challenged by Chief of Police Martin Lee.

The question remained, was the '13 Hole' postcard a response to the disappearance of Donna Lass? Shortly after her disappearance somebody rang her landlord and the casino to report Donna Lass had been called out to attend a family emergency. This in all likelihood was used to buy time, knowing that police will question family and friends first, before spreading their net wider afield. It appears the perpetrator may have known Donna Lass or was somehow connected to her. So to avoid any incriminating searches, the phone call may have been implemented to afford some breathing space. Additionally, it has become apparent she walked to work that evening from a previous residence, so her car was never parked outside the casino that night. If the perpetrator knew Donna Lass and the vehicle she drove, then a phone call to the casino implying she had been called out of town for a family emergency and would be away from work for a period, would be negated if her Chevrolet Camaro convertible was spotted sitting idle in the car park of the casino for any extended period. This may suggest she was carefully tracked that evening and the crime planned in advance. Was the killer close enough to Donna Lass to know her family lived in Beresford, South Dakota and the phone call had a better chance of buying time under these circumstances. The perpetrator also appeared to be fully aware of her shift details, as she vanished moments after changing from her nurses uniform into regular clothes.

The San Francisco Chronicle ran an article on the missing Donna Lass on September 26th 1970 entitled Nurse Vanishes...A Tahoe Mystery.  It stated "As the absence lengthened hotel officials contacted the South Lake Tahoe Police, who checked her apartment and could find no clue to her whereabouts. Relatives in Sioux Falls flew here a week ago".
So I suppose Zodiac's paraphrasing of the Mikado on July 26th 1970 stating "none of them will be missed" partly rang true, in the sense it bought him valuable time. The idea the Zodiac knew Donna Lass has its origin from the Letterman General Hospital, San Francisco, situated in the Presidio Park - the occupation she held prior to arriving in South Lake Tahoe just a few months earlier.          

The family after arriving in South Lake Tahoe would undoubtedly go through the usual appeals for information on the missing woman, and although the family would eventually offer a reward for any information, this came in early 1971 in the form of a cryptic poster and a 500 dollar reward. They also hired a private detective in the weeks after she vanished. What exact media appeals ensued in the month of September after her disappearance and to what extent, can only be imagined, but it could be argued the Zodiac clearly got wind of it.  Nine days after the San Francisco Chronicle article, the '13 Hole' postcard landed on their doorstep.

​This takes us back to "There are reports city police pig cops are closeing in on me. Fk I'm crackproof. What is the price tag now?" Could the killer, aware of the family's appeals to the media have responded personally. The thought has crossed many peoples minds that Fk may be somebody's initials. Had a police officer been quoted or a newspaper reporter written an article about the Zodiac Killer, suggesting the net was closing, and this was his response using the initials of the said person to reply? However, trawling every article on the Zodiac Killer has failed to throw up any possible name that fits with the initials, suggesting it may be wrong.

Gregory Haugevik, a Zodiac enthusiast, pointed out that the 'k' was not capitalized pouring serious doubts on the idea, unless of course the author simply had no capital 'K' to hand when pasting the card. Or in some subtle way, the lower case 'k' he used was a clue to the identity of the person he was addressing. The following may very well be incorrect, but this postcard was the first correspondence mailed by the Zodiac Killer after the disappearance of Donna Lass - and as stated above, it was mailed only nine days after the San Francisco Chronicle article - so in the absence of any reporter or police officer, is it likely the killer could be addressing the family of Donna Lass in his usual taunting manner. Donna Lass' father was James Lass and the maiden name of her mother was Frances Kukar - to become Frances Lass upon marriage.

"There are reports city police pig cops are closeing in on me. Frances Kukar, I'm crackproof. What is the price tag now?"  If the Zodiac Killer was aware of the maiden name, it may suggest him to be closer to the family than we dare to imagine, thereby casting a sinister overtone upon the card. On the other hand 'Fk' could simply mean F@@k.      

Another crime on the fringes of the Zodiac story was the likely abduction and murder of Donna Ann Lass from the Sahara Tahoe Hotel and Casino on September 6th 1970. Planning to meet her friend Jo Anne Goettsche immediately after her shift at 2.00 am, the only telltale sign that she had been interrupted, was a pen mark trailing off her log book, estimated at fifteen minutes to the hour. She had left her 1968 Chevrolet Camaro at the Monte Verdi Apartments and traveled to work from her previous residence by foot to begin her shift, planning to ride home to the new flat with her friend, but unfortunately this meeting never happened and the young 25-year-old woman was never seen again. This was Labor Day weekend, so obviously Donna Lass not returning to work in the following days may not have aroused concern, ultimately circumvented by an anonymous caller ringing her employer and workplace, and stating Donna Lass had been called to a family emergency.  

But what does the phone call tell us about the perpetrator/s?
It seems on the face of it, to suggest the mystery phone caller is buying time. They appear to want to delay any police involvement - and since family, friends and associates are usually the first port of call for investigating officers, this is who would benefit most from any investigative delay.
​
The perpetrator/s most likely had a vehicle parked outside the Sahara Tahoe Hotel, Abducting a woman at a busy casino and hotel by dragging her away on foot is extremely unlikely and far too risky. Whatever happened subsequent to this is in the realm of speculation, but one reason to want to buy time in the following days, can be attributed to a forensic standpoint. Had Donna Lass been taken to a second location connected to the abductor, or attacked within the confines of the assailant's vehicle leaving trace evidence, then clearly this provides good reason for the perpetrator to want the clean up before the police come knocking. A murder distinct and separate, leaving nothing of forensic value to connect to the perpetrator, does not necessitate the further risk of identification through a phone call. The phone call itself provides another clue. If Donna Lass had driven to work on the day in question, her car would have been laying dormant in the casino car park, so an anonymous caller claiming she had been called out of town on family business could easily have raised suspicion from her employers, and simply negated the caller's intention of buying time. In fact, it would have had the opposite effect. The same could be said regarding the landlord of the Monte Verdi Apartments, if the landlord was familiar with her vehicle or was regularly present on site.                    

It would also suggest the abductor was not aware of Donna's intention to meet her friend Jo Ann Goettsche that night, as she could easily have raised concern about Donna's non-appearance. Was the abductor familiar enough with Donna's movements that day, that told him she had not traveled to work in her vehicle that evening? She also disappeared close to the end of her shift, having already changed from her nurses uniform into her casual clothes - another convenient circumstance for the abductor. Had she vanished from her post, let's say, hours earlier, her disappearance would have certainly raised more eyebrows, indicating the abductor likely had some knowledge of Donna Lass prior to September 6th 1970 and thereby negating the idea this was a random perpetrator. The abduction of Donna Lass has all the hallmarks of a planned abduction by somebody familiar with the young woman, her vehicle and her 'clocking off' time. And more importantly, somebody who needs to keep the police off their doorstep for as long as possible.

Her Chevrolet Camaro parked outside her Monte Verdi Apartments and the apartment itself, showed no signs of foul play or disturbance. The likelihood is she disappeared from the vicinity of the casino at approximately 1:45 am to 1:50 am - and unlikely from her nurses station - as this would have attracted too much attention. As Zodiac researcher Raymond Grant has already stated, the likeliest scenario is Donna Lass was enticed away from her work station close to the end of her shift in a planned abduction, performed under the guise of a medical emergency, that not only explains the abrupt pen mark trailing off her log book, but is the perfect ruse to necessitate her separation from the confines of the building and into the darkness. She is bundled into the abductor's vehicle with relative ease and is never seen again.            

Apart from the four confirmed Zodiac attacks, the Bay Area killer would also indicate his involvement in the Richard Radetich murder, the Cheri Jo Bates stabbing and the Kathleen Johns abduction, however, here he doesn't specifically attach himself to the crime, just the locality of the crime, some six and a half months after the fact.
​
The phone call after the Donna Lass abduction is not unusual to Zodiac and neither is the mailed correspondence, but the nature of the crime is, along with the purpose of the phone call. His previous two phone calls were designed for menace and the taunting of police, whereas this call had the sole design to create breathing space, indicative of somebody connected to the victim and area. Of course, Zodiac could have been resident in the area, known Donna Lass and been the abductor. But from what we know of Zodiac's confirmed attacks, by all accounts, he attacked strangers at a specific location and never abducted them.
The phone call in the case of Donna Lass was designed to misdirect for a reason, and quite possibly the 'Pines' card was mailed for the same purpose; - the first to delay the focus and the second to take the focus away. This time the perfect fall guy would be Zodiac. However, one killer may have been responsible for both phone call and postcard and it may not be the killer we have been tracking for nearly fifty years.         

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

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

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

The Pines Card sent to the San Francisco Chronicle March 22nd 1971 has courted controversy on its validity as Zodiac correspondence, but it just may be the most important of them all. On first viewing it appears just a jumble of pasted words scattered randomly, but it is far from that, and along with the address side may hold the key to the entire story. It was possibly the Zodiac Killer's final attempt to push us in the right direction, to reveal the mind behind his murders and show us that religion, mathematics and coding were integral to virtually every letter, card and cipher he mailed to authorities.
Three correspondences, that of the 13 Hole Postcard mailed on October 5th 1970, the Halloween Card mailed on October 27th 1970 and the Pines Card mailed on March 22nd 1971 were as close as he would ever go to revealing the man behind the mask.
This article will cover old ground but expand slightly on the 'Hidden Message in the Pines' posting, but comes with a warning- if you are not a proponent of mathematics being used as a tool in unlocking the mystery of the Zodiac material, then it is wise that you progress no further. However, here, no mind bending techniques will be used. We will place the wording into the code and what falls out is the answer- nothing more.
The first thing to do is take everything back to basics- why did the Zodiac Killer choose the name Zodiac. When most people think of Zodiac the horoscopes come to mind- this is the simplest answer and this is maybe what our killer did. He used his own moniker of the crossed circle in all of his ciphers, so if he was to create a numeric answer to each card or cipher, he had to first apply a numeric value to his crosshairs. This was revealed in the Pines Card, but can be found in numerous other places.
The thought is, the Zodiac Killer developed his own key based around the 13 Symbol Cipher, although where it came from is not important. What is important though, is that it works in the 13 Symbol Cipher, the Button Letter 32 Symbol Cipher, the 13 Hole Postcard, the Halloween Card and the Pines Card, although the story may have began with the 340 Cipher.
So let's start with the Pines Card using the gematric code key the Zodiac chose.  

Notice in the Pines Card below we have placed the phrases into the code on the right to achieve a total of 315. This figure is also achieved by placing the entire Zodiac horoscope into the code. The 12 signs of the Zodiac are Aquarius (34), Capricorn (28), Sagittarius (56), Scorpio (26), Libra (15), Virgo (24), Leo (9), Cancer (18), Gemini (24), Taurus (31), Aries (22) and Pisces (28). These figures also add up to 315. But there was more. Placing the top row of the gematric code alongside the 13 Symbol Cipher, A through to M, and alphabetically   

counting the difference between each column, only the numbers 3,1 and 5 fall out. If we apply the gematric code directly to the letters A,E,N,K,M,N,A,M on the 13 Symbol Cipher, the figures 1,5,1,3,1,1,1 and 1 appear, again only the numbers 3,1 and 5. See below.
Lawrence Kane became a Zodiac suspect as he had worked at the same hotel as Donna Lass, missing, presumed murdered when she vanished after her nurses shift at the Sahara Tahoe Hotel on September 6th 1970. Strangely KANE is present on the left side of the 13 Symbol Cipher and KANE in the gematric code again only produces the figures 3,1,1,5, ie: the numbers 315 in order.
It was considered that this paste up card may have been indicating a burial site for Donna Lass, in view of the punch hole the author placed in the top right corner.  

However, this would have been too easy and a search of the site proved negative. The Pines Card depicted an advertisement for the Forest Pines condominiums near Clair Tappaan Lodge, Norden, California, located on Sierra Club property. The Clair Tappaan Lodge is exactly 315 degrees on a compass, when the compass is centered over the Sahara Tahoe Hotel, where Donna Lass went missing- so all may not be lost.
The circular punch hole nevertheless, still suggested a location of where Donna Lass may be buried and the author of the Pines Card had flipped the phrase 'around in the snow' 180 degrees, into an upside down position to suggest this.
You will notice that the phrase 'around in the snow' totals 56 in the code, yet when flipped 180 degrees, it reads 95.
This is very interesting because as explained in the 'Hidden Message in the Pines' article, when you place the left corner of the card over Clair Tappaan Lodge, dependent on scale, the punch hole falls over US Highway 95.  
U.S. Route 95 (US 95) is a major U.S. highway traversing the US state of Nevada from north to south, directly through Las Vegas and providing connections to both Carson City (via US 50) and Reno (via Interstate 80). US 95 is cosigned with Interstate 80, for 95 miles between a junction in Churchill County and Winnemucca before heading north into Oregon at McDermitt. (Taken from Wikipedia). View on Google Maps.
Was this the hint of a possible burial site, somewhere close to US Route 95 in Nevada.

This is a direct and fast route away from South Lake Tahoe into relatively barren terrain, heading towards parts of the Humboldt Toiyabe National Forest. View on Google Maps.
The Pines Card punch hole however, could equally fall near or over Pine Mountain situated within the Humboldt Toiyabe National Forest. It would have depended on the dimensions of the map he used and the correct measurements of the Pines Card itself, if indeed this was its purpose at all.
The green region on the map on the left, just to the right of the number 95, contains Paradise Peak. We now have Pine Mountain and Paradise Peak, and a possible source for the phrase 'Peek through the Pines'- but of course this is still highly unlikely.
Is it possible the Zodiac Killer owned or rented a cabin within this region, its remoteness is the perfect hideout- who knows.
If the Zodiac Killer did reside within the region of San Francisco, Vallejo or Benicia areas, then the phrase 'pass lake tahoe areas' from his perspective makes perfect directional sense, to discover any burial site. Your passing of the Lake Tahoe area, on a straight line, heads directly towards the region of Pine 

Mountain and Paradise Peak, seen here on the right. In fact, straight through Clair Tappaan Lodge It would exactly bisect these two landmarks.
So let us go back to our number 315, that is now representative of the Zodiac crosshairs and apply it to the 13 Symbol Cipher, 32 Symbol Cipher and 13 Hole Postcard.
It was suggested through many previous posts that the Zodiac Killer saw himself as some form of savior, delivering his victims to Paradise. In other words he was placing himself alongside Jesus, however uncomfortable a thought this vision may appear. It is not unusual for serial killers to have a religious agenda when they commit murder, albeit not the religion most people have grown up to understand.  
In Christian numerology Jesus is represented by the figure 888 and in English gematria Jesus is represented by the figure 444- so it would be highly improbable that if we used the Zodiac code he created for himself, along with the figure 315, that represented the Zodiac crosshairs, both unsolved ciphers would equal 444, and applied to the 13 Hole Postcard would equal 888. But that is exactly what happens.
The alphabetical characters on any code are directly placed into the gematric code key to give them a value, any symbols are simply converted to text form to give them a value.   

Take a look at the 13 symbol Cipher on the left.
​It was often questioned whether or not the symbols were either three 8's to give us 888 or they were three Taurus symbols. It is entirely plausible the Zodiac Killer circled them so they could be interpreted as either. The three Taurus symbols for example, are applied into the code as follows. 
TAURUS = 7+1+6+5+6+6 =31. But there are three, so 3 X 31 = 93. The whole code totals 444 or JESUS.
This technique is then applied in exactly the same manner to the Button Letter 32 Symbol Cipher (seen below) This time we have an Omega symbol, so again the code is applied.
OMEGA = 2+1+5+7+1 = 16

We can attribute a value to symbols, but not geometric shapes- for example, on the Button Letter cipher we have a triangle, or blacked in triangle, or black triangle, or solid triangle, or dark triangle. The point being- that the six geometric shapes cannot be attributed a specific name, to attribute a value to. So the 6 geometric shapes are only omitted for this reason, but everything that can be attributed a numeric value, has been. When totaled up, this cipher also equals 444.

Two unsolved ciphers totaling 444. And we know 444+444=888. But can we take this any further.
The 13 Hole Postcard conforms to this gematric code also.
When the phrases on the card are applied into the code the sum total of the card equals 888. It can be noticed that it leaves the name Jesus squarely alongside the name Zodiac on the postcard, declaring he was indeed the savior of souls. As with the symbols, the number 1 and 3 has been converted to text to attain a gematric value. This is not done for convenience, it is following the same principle throughout (See below). 
He even placed a red crucifix on the card to point us in the right direction. Also take a careful look at the very measured third line with the number 13 conveniently sandwiched in between- but this time leave the number as 13. The third line would now add up to 217+13+130, which equals 360. There are 360 degrees in a circle and the Zodiac did indeed punch 13 holes into the fabric of this card.

The Halloween Card and Pines Card could possibly have had a strong connection. The Zodiac gave us patterns of words on both. On the Halloween Card he gave us a form of cipher or cryptic message, by placing the words PARADICE and SLAVES in the form of a cross or crucifix.
It was previously noted that it was comprised of 37 letters, with 24 letters in the four quadrants. The Pines Card was comprised of 74 letters, exactly double that of the Halloween Card configuration, but we were left with the number 12 on the Pines Card, which conversely was exactly half of 24. However: 37 X 24 and 74 X 12 both equaled 888 once again.

One more curiosity was the envelope or address side of the Halloween Card, in which he misspells Paul Avery to Paul Averly and underlines it. Why did he do this?
The idea that the Zodiac Killer designed his Halloween Card based on the Rota Fortunae or Wheel of Fortune, was inspired after reading a thread on the ZodiacKillerSite forum. The discovery was made by Tahoe27, when she noticed that a comic strip publication bore striking similarities to the October 27th 1970 offering from the northern California killer.
The Red Ryder comic strip was created by Stephen Slesinger and Fred Harman in 1938, and there was one particular publication entitled 'Tim Holt: The Death Wheel' that caught her attention.
The Death Wheel contained the four methods of death, the same as the Zodiac Killer had placed around his cross of Paradice and Slaves- By Gun, By Rope, By Knife and By Fire. Moreover, the word 'By' was styled in near identical fashion. The Death Wheel in its entirety, showing the 12 methods of death, places the four Zodiac methods of murder in exactly the same order as we travel around the wheel, and the use of the wording 'Lady Doom' reminds us of the wording around the knothole of the tree on the Halloween Card, where the Zodiac Killer places the phrase 'Peek-a-boo you are doomed'. Not only that, he designs it in a circular fashion.
Furthermore Fred Harman owned a ranch in Pagosa Springs, Colorado, where a particular style of cattle branding would elevate this finding to the next level, when the branding itself was compared to the strange symbol the Zodiac Killer placed on the Halloween Card envelope and the foot of the card once opened. Apart from the four dots, it is strikingly similar.

But after all is said and done, can we verify that this gematric code has any basis in fact, or could it all be coincidence. The Zodiac Killer yet again gives us the misspelled name of Paul Avery on the address side of the Pines Card, exactly like he did on the Halloween Card. But this time he writes att.Paul averly = Chronicle- meaning attention. Paul Averly = Chronicle.
​ But what does he mean and what is he saying. It is a curious phrase, that is, until you place it in the gematric code once again. It now makes perfect sense, and is just another clue, in a long list of clues the Zodiac Killer was pushing in our direction. 

PAUL AVERLY = 3+1+6+2+1+5+5+5+2+2 = 32
CHRONICLE = 3+6+5+2+1+5+3+2+5 = 32
And 32 does indeed equal 32.
This is why the Pines Card was the most important card of all, it tried to point us towards the number 315, that was integral to all the unsolved ciphers- and the address side was the final stamp of approval.

On the 22nd March 1971, a postcard landed at the offices of the San Francisco Chronicle, that has become widely known as the 'Pines' card. It was this correspondence in particular that caught the eye of police officer Harvey Hines, who after extensive investigative work became utterly convinced Lawrence Kane was the most likely candidate for the five Zodiac murders, committed from December 20th 1968 to October 11th 1969. Although the Zodiac Killer's reign of terror appeared brief, Harvey Hines was convinced that it may have been a lot longer, in that, where Lawrence Kane moved, murder would soon follow. He noticed certain locations and timelines that spiked his interest, placing Lawrence Kane to the forefront of his focus and started nigh on three decades of dedication to unearthing the truth. He provided a intriguing case against his suspect permeated by a solid case history, although it appears that much of it fell on deaf ears as Lawrence Kane was relegated to the fringe of the Zodiac suspect list.   

It was the hunt for missing nurse Donna Ann Lass that became a near obsession for Harvey Hines, becoming closely allied to the family members of the young 25-year-old as he searched undaunted for a break in the case. He has to be commended for his devotion in and out of police hours, when many others seemed to have lost hope.
The story began when the Zodiac Killer turned into the isolated turnout of Lake Herman Road on December 20th 1968 and appeared to have ended when the murderer exited the taxicab of Paul Stine on October 11th 1969 and disappeared, heading north into the darkness of Cherry Street towards the Presidio. But in fact the story was only just beginning.

After the murder of Paul Stine the killer headed towards the Julius Khan Playground, but whether he actually ended up there, as he alluded to in his October 13th 1969 letter to the San Francisco Chronicle, has been the topic of much debate. Donna Lass worked in the Presidio at the Letterman General Hospital and lived at 4122 Balboa Street, San Francisco. The murderer of Paul Stine, based on the taxicab meter reading, was believed to have flagged down the taxicab in the theater district, near the corner of Mason and Geary Street, and an area situated less than a quarter of a mile from the Lawrence Kane residence at 217 Eddy Street. For all these relevant locations, click here for Google Maps. 

But this may be about to change, due to the persistent work of Zodiac enthusiast Alex Lewis (Welsh Chappie), an avid member of the ZodiacKillerSite forum. On Monday April 7th 2014, after multiple Freedom of Information Act (FOIA) requests, he finally received the information he had been searching for. The United States Department of Justice sent him some valuable information regarding his prime suspect Lawrence Kane, including a full and complete arrest sheet, with a lot more besides. (See foot of page for two examples). Alex Lewis, as well as contributing to the popular ZodiacKillerSite forum, has dedicated many hours compiling extensive information on his favorite suspect Lawrence Kane. His comprehensive Wordpress site can be viewed here. These interesting findings have also generated a discussion thread on the ZodiacKillerSite forum; so to contribute your thoughts please visit the topic here.  htttp://www.zodiackillersite.com/viewtopic.php?f=43&t=1536.

Harvey Hines remained undeterred, when many others had given up hope - and even though the search for Donna Lass has hit many dead ends in the intervening years, the hope that was held by Harvey Hines still lives on.   

Much controversy has surrounded the Pines Card since it was mailed to the San Francisco Chronicle on March 22nd 1971, received exactly one year after the abduction of Kathleen Johns on March 22nd 1970. Kathleen Johns recounted her terrifying ordeal at the hands of the Zodiac Killer, whereby the stranger had disabled her car, tampering with the wheel nuts, in the pretense of offering her his assistance.
The Pines Card has always been controversial, in particular, that it 'sought victim 12', out of sequence with the attributed numbers on other Zodiac correspondence, but here we will show that the apparent random phrases on the card, could very well have contained a hidden message and indeed the number 12 was integral to the structure of the card.
On the card the author added five lines of text, 'Sierra Club', 'around in the snow', 'sought victim 12', 'peek through the pines' and 'pass Lake Tahoe areas'. This array of text has often been linked to Donna Lass, who disappeared after finishing her shift at the Sahara Tahoe Hotel, Nevada on September 6th 1970.
In a previous article it has been demonstrated that the Zodiac suspect Larry Kane can be found in the My Name is...Cipher, using a technique involving English gematria and the seven days of creation. VISIT HERE for explanation.
The Zodiac Killer chose his crossed circle for a reason and uses it throughout his many letters, cards and ciphers. In later cards, such as the 13 Hole Postcard and the Pines Card, he goes one step further, actually punching circles into the fabric of the card, while still including his trademark crossed circle within the design and this is where the thought of pi has originated down the years. Indeed, the Zodiac Killer incorporated the idea of radians into several of his letters.   

Jesus Christ and the astrological Zodiac have many parallels, in fact Jesus, the Sun and the planets can be shown together throughout history. 
The 12 disciples of Jesus Christ (59), after the betrayal, were Matthew (31), James (17), Thomas (23), Bartholomew (37), Philip (24), John (13), Andrew (20), James (17), Simon (15), Peter (25), Judas (21) and Matthias (34). Next we work out the gematric values of the 12 disciples and Christ, using the seven days of creation code above. (eg; Matthias is 1+1+7+7+6+5+1+6=34).
Then we add up the values of all of them, shown in brackets above, to arrive at a grand total of 336.
The 12 signs of the Zodiac are Aquarius (34), Capricorn (28), Sagittarius (56), Scorpio (26), Libra (15), Virgo (24), Leo (9), Cancer (18), Gemini (24), Taurus (31), Aries (22) and Pisces (28). These total up to 315. For the full explanation visit this video on Youtube by Marty Leeds. 
Now lets examine the Pines Card, the wording on the card (excluding the number 12 after 'Sought Victim') and their numerical values in the gematric code above.
SIERRA CLUB = 40
PEEK THROUGH THE PINES = 93
AROUND IN THE SNOW =56
PASS LAKE TAHOE AREAS = 66
SOUGHT VICTIM 12 = 60
The sum of the totals equal 315, exactly the same as the 12 signs of the Zodiac.
This leaves one thing left to do, that is add in the number 12, written in text form as ONE TWO, exactly like the rest of the card. This has a gematric value of 2+1+5+7+4+2 = 21. Now add the 21 to the 315 to arrive at 336 and the twelve disciples of Christ once more.
In another article http://www.zodiacciphers.com/1/post/2014/02/the-name-on-the-13-hole-postcard.html, it is shown the possible reasoning behind the upside down text on the 13 Hole Postcard, in that it may reveal a name.
The Pines Card also contains one line of upside down text. In this instance he pastes the words 'Around in the snow', but is there an explanation for this also.
This card as explained earlier, has primarily been associated with the disappearance of Donna Ann Lass from Stateline, Nevada on September 6th 1970 and the card was possibly a clue to where her body could be discovered. The words 'Around in the snow', placed upside down, had overtones of a likely burial site, so it seemed only logical to examine this phrase as having greater significance and see if we can narrow down a possible area of interest.
The Pines Card depicted an advertisement for the Forest Pines condominiums and the Sierra Club. An excavation took place at what appeared to be a grave site near Clair Tappaan Lodge, Norden, California on Sierra Club property, by Harvey Hines, a law officer who retired from the California Police Department in 1992, along with Zodiac researcher Dave Peterson. The punch hole in the top right of the card in the woods suggested an area of great interest. Upon inspection a circle of logs 16 feet in diameter were discovered, inside this was a square and a circle, along with a 13 stone cross, but after a thorough examination of this site no body was found. But there may be another likely burial site.
The Zodiac Killer possibly believed the logical assumption by authorities and police after receiving the Pines Card, was to enter the Sierra Club site to examine the 'punch hole' area, but being the master of misdirection, the hole in the card was actually pointing away to a second site and once the card was aligned from this 'fake' grave site, the real location point would be unearthed.   
Firstly lets examine 'Around in the snow', using the gematric code above. This phrase adds up to 56, but it is upside down.
If we flip the number 56, we get 95.

'Peek through the pines' may suggest a wooded area and all within ease of access off the US Route 95 in a direct route away from the Sahara Tahoe Hotel where Donna Lass was last seen.

The ecliptic passes through 12 constellations to form our Zodiac, used in horoscopes to predict the future. The Zodiac Killer sent us the 'Bus Bomb' letter, to which he displayed a crosshair at the foot of his correspondence, marked with five crosses and dotted sections to separate the circle into 12 equal divisions of 30 degrees. There was a possibility this was to become his compass or template to his crimes, the ones he had already placed X's next to and the remainder, as he stated at the top of the 'Bus Bomb' letter on November 9th, that would not be announced. He wrote ' up to the end of Oct I have killed 7 people. I have grown rather angry with the police for their telling lies about me. So I shall change the way the collecting of slaves. I shall no longer announce to anyone. When I committ my murders', but he was to leave us a clue. Image of the 'Bus Bomb' crosshair with X's.  

But what we shall examine here is the statement the Zodiac wrote on the 340 Cipher and 'Dripping Pen' card, namely "This is the Zodiac speaking.  I though you would need a good laugh before you hear the bad news. You won't get the news for a while yet", implying his evil deeds were not far away. His next confirmed contact after this, was the Melvin Belli Letter claiming a search for a ninth and tenth victim - and by inference victim number 8 had already been secured.

A 10th victim was confirmed by the arrival of the 'My Name is Cipher' on April 20th 1970. This correspondence could have read Zodiac 12 SFPD 0, if the Zodiac Killer had been successful in the murder of Kathleen Johns and her infant daughter, one month earlier on March 22nd 1970 - commonly referred to as the 'Modesto Attack'. This crime may not have been the work of Zodiac, but he claimed it was, and not something he was about to forget.

The Zodiac Killer's three early crimes were in static locations - that is - he did not coerce or force his victims to a predetermined location. It has been suggested by some Zodiac researchers that the Paul Stine murder was chosen because of his ability to manufacture an exact grid position to fit his location point on the 'Bus Bomb' letter crosshair. The next two incidents strongly linked to the Zodiac Killer were the Modesto abduction of Kathleen Johns on March 22nd 1970, followed by the Donna Lass disappearance on September 6th 1970, with one or both employing the use of a car to abduct the victim and again, maybe with the intention seeking out his predetermined grid location. But there is another reason that may link both Kathleen Johns and Donna Lass.

The Zodiac Killer could quite easily have shot Kathleen Johns through the driver side window of her vehicle as he had done at Blue Rock Springs Park, but chose to subject his victim to what appeared an aimless drive around the countryside of Tracy, CA, after which she escaped to a nearby field. If this was a Zodiac crime, was the Bay Area murderer possibly aiming for somewhere in the region of Antioch, CA, which falls directly on the north-east line on the map above, and conveniently on the way back to the Vallejo area where it has been widely speculated that he resided. 

Kathleen Johns may have denied the Zodiac Killer his 11th and 12th victim this time, but was he to remind us of it exactly one year later on March 22nd 1971, when the disputed 'Pines' card landed at the door of the San Francisco Chronicle. The reason behind its design is not certain, but what was apparent, is that the largest writing on the 'Pines' card was "Sought Victim 12" written in the past tense. Was this an indication that he had indeed sought his 12th victim, but failed? This card signifying 12 was out of sequence with the the other cards, because it came after the 'Little List' letter on July 26th 1970 claiming a victim count of 13, the '13 Hole' postcard on October 5th 1970 also claiming 13, the 'Halloween' card on October 27th 1970 inferring a 14th victim and the 'Los Angeles' letter on March 13th 1971 claiming 17+ victims.

The Zodiac Killer sent the 'Pines' card 6 months after the disappearance of Donna Lass. This significant delay may have been orchestrated to tie in with the anniversary of the Modesto attack, emblematic of the fact he was unable to place Kathleen Johns on the north east grid line (shown above) as intended on the 'Bus Bomb' map - so he found a replacement on the exact same grid line, that of Donna Lass at South Lake Tahoe - and inextricably linked them both by the number 12 and March 22nd.
