At a time when finding Zodiac Killer DNA and solving this case is heavily debated and in question, one of the most important things to explore are the vast number of communications sent by the killer, with a view to unearthing something within them that points towards his identity and/or home location (anchor point) when committing the murders. No doubt the Zodiac Killer used caution in this regard when composing his communications, but no matter how careful and attentive you are in preventing the accidental leakage of vital information to law enforcement through your wording, mistakes and oversight can often happen. When a murderer is questioned about a missing person, they will often stray into the territory of referring to that missing person in the past tense, because they are knowledgeable to the fact they have killed them. The study of language in interviews and written form can often reveal vital information about a criminal which they have subconsciously revealed, but were incapable of preventing because of their lived experience.

​This may have been the case in the very first letters authored by the Zodiac Killer on July 31st 1969 and August 4th 1969, both of which, possibly revealed the home location of the killer (or his anchor point when perpetrating the crimes). You will notice in his July 31st 1969 letters when addressing the San Francisco Chronicle or San Francisco Examiner first, the Zodiac Killer refers to posting letters to these newspapers in the past tense of "have". In other words, suggesting the significant time that has elapsed, and the distance he has traveled before returning home. When first addressing the Vallejo Times-Herald in his July 31st 1969 letters he uses the present tense of "are", because (possibly) he doesn't associate any great time and distance to the Vallejo Times-Herald offices, as they are within his close proximity. They are in his "here and now". If you left your house in Vallejo and mailed three letters into a San Francisco mailbox, before returning home - you would write "Here is a cyipher or that is part of one. the other 2 parts have been mailed to the S.F. Examiner + the S.F. Chronicle" (associating distance to these two newspaper offices). If you live in Vallejo and are addressing the Vallejo Times-Herald first in two instances, you would write "Here is a cipher or that is part of one. The other 2 parts are being mailed to the Vallejo Times + S.F. Chronicle" or "Here is part of a cipher the other 2 parts of this cipher are being mailed to the editors of the Vallejo Times and SF Examiner". The Zodiac Killer uses the word "are" in both instances he immediately addresses the Vallejo Times-Herald offices (because he doesn't associate distance to this newspaper office). He uses the present tense of "are" to associate something in his lived "mental map" or "here and now". Of course, this isn't conclusive evidence he lived in Vallejo for his first two crimes, but it may point to a subconscious use of language that he failed to keep in check. There is similar language used at the beginning of his next communication on August 4th 1969.              

The following reasoning may seem innocuous and insignificant, but it's just another example of how language could point us in the direction of a Vallejo killer. When the Zodiac Killer opened up in his August 4th 1969 mailing, he wrote "This is the Zodiac speaking. In answer to your asking for more details about the good times I have had in Vallejo, I shall be very happy to supply even more material". What he didn't write is this:"This is the Zodiac speaking. In answer to your asking for more details about the good times I had in Vallejo, I shall be very happy to supply even more material". The Zodiac Killer used the present perfect tense of "have had" rather than the past tense of "had". The present perfect tense, in this example, suggests that the Zodiac Killer has had good times in Vallejo but they are not complete. The word "had" implies a distinct separation from the past to the present, whereas "have had" implies a distinct connection from the past to the present. The "good times I have had in Vallejo" being congruent with somebody still living in this location. Although tenuous, this subtle use of language is important to analyse in conjunction with the previous example highlighted  The third example will focus on the anomaly of a phone call made to the Vallejo Police Department 40 minutes after the Blue Rock Springs attack, from a payphone located just 10 minutes from the crime scene. 

It has been widely noted that a killer living in San Francisco, Napa, Oakland, or any distant home location, could easily have made this phone call at 12:40 am from any payphone in the Bay Area, rather than place a phone call in close proximity to the police station he was delivering his message - and seemingly hanging around for an unnecessary 30 minutes, thereby risking detection. This has opened up the notion of a killer who lived in close proximity to the Springs & Tuolumne payphone, who secured his vehicle, removed any incriminating evidence and walked to the payphone from a nearby residence. This is where further language analysis could point us to a Vallejo resident, or otherwise. It depends on what merit you apply to the above arguments, in conjunction to the ones I'm about to present. ​      

The Zodiac Killer went on to write "I did not leave the cene of the killing with squealling tires + raceing engine as described in the Vallejo paper. I drove away quite slowly so as not to draw attention to my car", and "When I hung the phone up the damn thing began to ring & that drew his attention to me + my car". In the second statement the Zodiac Killer felt the necessity to highlight both him and his car. The phone apparently rang when he hung up the phone, so why didn't the Zodiac Killer just state "When I hung the phone up the damn thing began to ring & that drew his attention to me".

When he left the Blue Rock Springs parking lot he made the point of driving away slowly so as not to draw attention to his car, yet by the payphone he is making sure that investigators draw the conclusion that the eyewitness saw both him and his vehicle, despite apparently positioned at the payphone independent of his car. It could be concluded that his car was still running, and it would have been obvious to the eyewitness that he and his vehicle were in tandem (and so provided this information), but it certainly wasn't necessary to provide investigators with corroboratory evidence that his car was brown as reported in the newspapers, by stating "The man who told police that my car was brown was a negro about 40-45 rather shabbly dressed. I was in this phone booth having some fun with the Vallejo cop when he was walking by". Unless of course, his vehicle wasn't brown, The biggest red flag to his vehicle being present in the vicinity of the payphone, is the description given by the Zodiac Killer about the eyewitness.

The Zodiac Killer only went into detail regarding his murder victims when it benefited his case of proof, such as the description of clothing worn by Darlene Ferrin, or the movement of the living victims and bodies in relation to the crime scene. So why didn't the Zodiac Killer just write "The man who told police that my car was brown, noticed me + my car when he was walking by". What relevance does his race, clothing or age have to do with anything? The descriptive nature of "negro", "40-45" and "shabbily dressed" brings this eyewitness to life and makes him more believable to the reader of the letter. The Zodiac Killer, by describing this man in detail, may have been attempting to corroborate that his vehicle was present by the payphone, and was brown in color. The Zodiac Killer had previously supplied extra details to the police when it helped his cause, so the unnecessary inclusion of this man's description in the letter, could again, be viewed as beneficial to him. If the Zodiac Killer wanted to deflect away from a home location nearby, he had to create a vehicle that can take him anywhere, and supply an eyewitness to corroborate this fact. Not just any eyewitness, but a believable middle-aged, black man, with questionable clothing.   

These observations regarding the language used by the Zodiac Killer are not proof he resided in Vallejo or near the payphone, but they should provide the impetus to examine later communications mailed by the killer, who may have unwittingly left more offerings to further bolster the case argued here. Or maybe dispel it entirely.   

Edward Theodore Gein, dubbed The Butcher of Plainfield, was found guilty in the first degree murder of Bernice Worden (58), who was abducted and later found hung and decapitated in a shed on Gein's property. Although he was only convicted of one murder and found criminally insane, Edward Gein was believed to have killed many more, including Mary Hogan (51), Georgia Weckler (8) and Evelyn Hartley (15). Called the "House of Horrors", his property in Plainfield, Wisconsin revealed the true depravity of an individual who had lost touch with reality, when detectives found a lampshade made from a human face, a waste basket made from human skin, a corset made from a female torso and bowls made from human skulls, to name just a few of the macabre offerings.

His mother, Augusta Wilhelmine Gein (who died on December 29th 1945), was a domineering woman with an intense hatred for females, but whose death from a stroke left Edward Gein devastated and alone in the farmhouse. Soon after his mother's death, Gein began to create a "woman suit" so that "he could become his mother and literally crawl into her skin". He would achieve this by exhuming the bodies of recently deceased middle-aged women from local graveyards and using their skin to fashion his grizzly creations. 

A well read Zodiac Killer was seemingly inspired by the continuing fascination of the story of Edward Gein, that featured in many movies, beginning with Psycho (1960), produced and directed by Alfred Hitchcock, and starring Anthony Perkins and Janet Leigh, along with later productions such as The Texas Chainsaw Massacre (1974) and The Silence of the Lambs (1991). The Zodiac Killer mailed a cryptogram and letter in the middle of 1971 (likely early May) claiming the murders of Kathy Bilek (18), Debra Furlong (14) and Kathie Snoozy (15), who had all been recently attributed to Karl Francis Werner in the newspapers. The Zodiac Killer would make reference to all three girls in his 148 character and letter, asking investigators not to listen to "phonys" such as Werner, and warning them he would "skin three little kids and make a suit from the skin", and "send a patch of human skin if their is some left over". Having claimed the brutal stabbing of Snoozy and Furlong on August 3rd 1969 in San Jose through the "Aug" reference in his November 8th 1969 "Dripping Pen" card, he was now left with the necessity of claiming the stabbing of Kathy Bilek also. She became the focus of his later Monticello card, mailed on July 13th 1971, stating "Near Monticello Shought Victims 21 ...... In The Woods Dies April". ​ Kathy Bilek was stabbed in the Villa Montalvo woods in Saratoga (near San Jose) on April 11th 1971.  

Edward Theodore Gein was determined to raid graveyards and "make a woman suit from the skin", whereas the Zodiac Killer promised to "skin three little kids and make a suit from the skin". Kathy Bilek was buried in the Madronia Cemetery in Saratoga, Debra Furlong in the Oak Wood Cemetery in Santa Cruz, and Kathie Snoozy in the Oak Hill Memorial Park & Cemetery in San Jose.

I have always assumed that the Zodiac Killer was promising to kill three more kids in the future and make a suit from the skin, but based on the possible inspiration of the Edward Gein story, was the Zodiac Killer suggesting the macabre intention of visiting the three graveyards of Snoozy, Furlong and Bilek, and removing their skin to create a suit? Then mail "a patch of human skin if their is some left over". 

This may seem far-fetched, until you discover that Kathie Snoozy was buried in the Oak Hill Memorial Park & Cemetery in San Jose, located in the neighborhood of Monticello, near Saratoga. Hence the wording "Near Monticello Shought Victims 21 ...... In The Woods Dies April" in the Zodiac Killer's message on July 13th 1971. The neighborhood of Monticello is near to the Villa Montalvo woods in Saratoga, where Kathy Bilek was brutally stabbed to death on April 11th 1971. There is no doubt that the Monticello card is referring to the murder of Kathy Bilek, through the gravesite of Kathie Snoozy - and so linking the Zodiac Killer to all three girls. But did the 148 character cipher and letter have a much more sinister connotation to its contents than first thought, inspired by the continuing story of Edward Theodore Gein?   

Rolland Lin Taft (27) was gunned down and killed on April 20th 1974 by Los Angeles police officer, Robert Nava, who responded to Taft brandishing a .25 caliber automatic pistol by shooting him five times. His parents filed a speculatory 3.5 million dollar lawsuit against the Los Angeles Police Department claiming there was no reason for their son to have been killed. Rolland Lin Taft had previously attempted to murder a young woman (Atwood) on the Riverside City College campus on April 13th 1965 by stabbing her in the stomach with a hunting knife. Fortunately, the young woman was able to escape and seek help from local residents, who summoned the emergency services.

​One newspaper ran with the headline "Clean-Cut Youth Sought in Stabbing" (credit to Mk-Zodiac), and Taft was eventually apprehended and sentenced to 6 months to 20 years in March, 1966. He served just 2 1/2 years and was paroled in 1968. This newspaper headline (a tactic used by the Zodiac Killer in later years) may have formed the inspiration for the "cut, clean" introduction written on the underside of a plywood desk found in the Riverside City College library in December, 1966. The poem, created using a blue ballpoint pen, read "cut, clean, if red/clean, blood spurting, dripping, spilling; all over her new dress. Oh well, it was red anyway. Life draining into an uncertain death. She won't die, this time someone'll find her. Just wait till next time. rh". For many reasons, it is fairly evident that this poem is reminiscing in the present tense the attempted murder of Miss Atwood in 1965, before stating that "next time" would be different with the death of Cheri Jo Bates on October 30th 1966.  

You may read claims on the internet that this poem was the ponderings of a suicidal woman reflecting on her failure to seek death, but next time would be successful. It will be proffered that the idea of this poem being linked to Miss Atwood and Cheri Jo Bates is speculative at best. However, this couldn't be further from the truth. This poem wasn't even discovered until the December of 1966, so anything contained in the November 29th 1966 Confession letter (about Cheri Jo Bates) that links to the desktop poem, will have been created without knowledge of the desktop poem - unless the author was one person. By linking the two communications together, we would achieve the common thread of one individual who was claiming he murdered Cheri Jo Bates. The contents of the desktop poem were also not in the public domain by April 30th 1967, when the three Bates letters were mailed to the Riverside Press-Enterprise, Riverside Police Department and Joseph Bates.      

Firstly, all we have to do to connect the desktop poem with the Confession letter, is look at the title of the desktop poem, which reads "Sick of living/unwilling to die". The desktop poem begins with "Sick of living", and the Confession letter states "I am not sick. I am insane". The desktop poem title uses the word "unwilling", to which the Confession letter states "She was then very willing to talk to me" and "She went very willingly". One referenced an unwillingness to die, whereas one claimed Cheri Jo Bates went "willingly" to her death. In other words, Miss Atwood resisted her death and didn't die "that time", but Cheri Jo Bates died hard and willingly. The desktop poem title uses the phrase "to die", with the Confession letter stating "I said it was about time. She asked me "about time for what". I said it was about time for her to die". This brings forth another connection between both communications with the word "time" central to both. The desktop poem uses the word "time" twice, when stating "She won't die, this time someone'll find her. Just wait till next time", whereas the Confession letter uses the word "time" three times by stating "I said it was about time. She asked me "about time for what". I said it was about time for her to die". We have the words "sick", "unwilling" (in root form) and "time" from the desktop poem, used 6 times in the Confession letter by way of "sick", "willing", "willingly", "time", "time" and "time". In fact, the words "die" and "time" are used in the same context in both communications by the sentences "she won't die, this time someone'll find her" and "I said it was about time for her to die". If you add in the three Bates letters of "Bates had to die", "She had to die" and "She had to die" into the equation, we have the phrase "to die" used 5 times in all three communications.

Miss Atwood escaped the clutches of Rolland Lin Taft in 1965, expressed by the desktop author when they stated "she won't die, this time someone'll find her", but reminded everybody that the next time Cheri Jo Bates wouldn't be so lucky by finishing the poem with "Just wait till next time. rh". That "next time" was Riverside, Halloween, denoted by a lower case "r" and "h".

​The Zodiac Killer would address Riverside in lower case fashion when describing his "riverside activity" on March 13th 1971, using the phrase "there are a hell of a lot more down there" to deliberately or inadvertently mimic the three Bates letters of "There will be more". Despite Cheri Jo Bates being killed on October 30th 1966, her exact time of death was not confirmed by the newspapers, who described her lifeless body being found on Halloween morning. It is perfectly reasonable to conclude that "rh" was the place and time of that "next time" cited by the desktop author. The overwhelming correlation of language used by the desktop poem, Confession letter and Bates letters, ties all three to the murder of Cheri Jo Bates, and thereby strengthens the argument that the desktop poem was reflecting on the attempted murder of Miss Atwood and eventual murder of Cheri Jo Bates on the same Riverside campus by knife. Rolland Lin Taft was incarcerated at the time of Cheri Jo Bates' murder, so the desktop poem was either authored by somebody inspired by the previous attempted murder of Miss Atwood to make the future false claims of killing Cheri Jo Bates, or was indeed, the murderer of the young Ramona High School graduate - but, in their eyes, improved on the failings of Rolland Lin Taft by stating "Just wait till next time. rh".

The Confession letter concluded with "I am not sick. I am insane. But that will not stop the game", "I am stalking your girls now", with the three Bates letters finishing with "There will be more".  This was the bedrock of the three July 31st 1969 letters mailed by the Zodiac Killer, who enciphered the wording "it is more fun than killing wild game in the forest because man is the most dangerous animal of all" and promised more murder over the weekend. It appeared that the Zodiac Killer was still playing the "game" and "stalking" the local residents three years later. The Confession letter and murder of Cheri Jo Bates were comprehensively detailed in the Inside Detective magazine on January, 1969, so it's perfectly feasible that the Bay Area murderer read this magazine sometime between January and July and drew inspiration for his July 31st 1969 mailings by continuing the theme of a "game", despite being innocent of any involvement in the murder of Cheri Jo Bates or subsequent communications in 1966 and 1967. This may have continued in the Melvin Belli and Little List letters, misspelling the word "victim" to "victom", and mimicking the Confession letter further by adding "Some I shall tie over ant hills and watch them scream + twich and sqwirm" to appear similar to "She squirmed and shook as I chocked her, and her lips twiched. She let out a scream once". Whether or not the Zodiac Killer played any role down south has far from been answered, but there remains little doubt that one person crafted all three communications in Riverside between October 31st 1966 and April 30th 1967.   

One of the cornerstone arguments I put forward for the 1978 letter being genuine, was the fact that the introduction of "This is the Zodiac speaking I" on April 24th 1978 mimicked the introduction on the December 20th 1969 Melvin Belli letter. The 1969 and 1978 letters were the only two communications to date that failed to exclusively keep "This is the Zodiac speaking" as the introduction on the top line, with the grammatical error of not placing a "period" or "full stop" between "speaking" and "I" common to both. Bearing in mind that these two communications were connected through the word "control" (unique to these two letters), meant that if an image of the Melvin Belli letter had not appeared in the newspapers to date, the author of the April 24th 1978 letter likely fashioned the Melvin Belli letter, with added shirt piece. This was used to argue (along with other reasons) that the Zodiac Killer was the author of the 1978 letter.

​To his credit, notable Zodiac researcher Cragle unearthed an article in The Napa Register on December 29th 1969 that dispelled this notion (see below). But when I proposed the idea - asking people to check if a newspaper image of the Melvin Belli letter existed - it took two years to achieve. This is with the combined power of the Zodiac internet community, and a comprehensive newspaper database at our fingertips. 

The author of the 1978 letter had none of these advantages. Often described as a "lazy" hoaxer by document examiners, the author of the 1978 letter could have accessed the above article to mimic, by keeping hundreds of newspapers featuring the Zodiac Killer since 1968, by keeping hundreds of newspaper cuttings about the Zodiac Killer, by trawling through the microfiche of a public library, or they just got extremely lucky in mimicking the introduction (with grammatical error) and the use of the word "control", common to both letters. But there is another common theme binding these two letters, which is not visible in the article above. The Melvin Belli letter on December 20th 1969 and the April 24th 1978 letter both inserted an unnecessary word (just once) into the correspondence, spelled it correctly one alphabetical letter shy of completion, and then very neatly (almost ruler like) crossed out each word. This was unique to both these letters. 

If somebody can find this section of the Melvin Belli letter in the newspapers (showing this correction technique), I will be eternally grateful. Is it more likely that the Zodiac Killer crafted the 1978 letter, with personal knowledge of the Melvin Belli letter and its composition, or is it more likely that a random hoaxer (described as lazy) went to extraordinary lengths to mimic the Melvin Belli letter? Or was the presumed hoaxer of the 1978 letter just lucky, creating all these similarities by accident? 

The April 24th 1978 letter, stating "I am back with you. Tell herb caen I am here" was postmarked only 42 days after a voice message was left on the telephone answering machine of an individual living in the Mission District, using similar wording to that used in the letter, and claiming to be the "Zodiac". The telephone caller stated "This is the Zodiac. Tell the press I am back in San Francisco".  Read more. Was this the Zodiac Killer twice, or the hoaxer twice?

​Thanks to Cragle, another unusual mention in the above newspaper article may be relevant to 1978. It may indicate that the person who crafted the April 24th 1978 and May 2nd 1978 letters were one and the same - who had kept or read The Napa Register publication. The article above finished with the following text.

The newspaper article stated "Belli said that he has a trial starting next week in Naples and plans to confer with fugitive Black Panther Eldridge Cleaver".​ Just eight days after the April 24th 1978 letter, on May 2nd 1978, the Channel 9 letter was mailed to KHJ-TV Studios, 5615 Melrose Avenue, Los Angeles,.claiming to have been mailed by the Zodiac Killer, It too mentioned Eldridge Cleaver. Bearing in mind the similarities between the April 24th 1978 and Melvin Belli letter, it is extremely curious that the very newspaper article that featured the grammatically unique introduction common to these two communications, would also feature the name of Eldridge Cleaver, that appeared in a "Zodiac" letter only eight days later.
