The full Tit-Willow verse read "my name Isn't Willow, tit-willow, tit-willow", so could this have featured in the 13 character code? The Zodiac Killer could have playfully used Tit-Willow as his name on April 20th 1970, before reversing this on January 29th 1974 by invoking the Tit-Willow verse in his Exorcist letter. The proposed suggestion being "My name is only Tit-Willow". Although this solution fails by using the plaintext letters "T" and "I" to represent the ciphertext "circled 8", the three "circled 8's" can spell "TIT". One would like to believe that the Zodiac Killer - knowing his 13 character code was practically unsolvable - would have given us a clue in his later letters. So was the "Signed, yours truley" phrase, followed by "my name isn't" in 1974, that clue?
On January 29th 1974 the Zodiac Killer tempted us with his name by writing "Signed, yours truley" and then placing an extract from The Mikado's Tit-Willow verse. The implication being that the Zodiac Killer's name may be found within the verse. In 2017, I noticed that the complete Tit-Willow verse from Gilbert & Sullivan's play had the phrase "my name is" within the wording "my name isn't", reminiscent of the April 20th 1970 letter stating "This is the Zodiac speaking. By the way have you cracked the last cipher I sent you? My name is....", followed by a 13 character code.

So was the "Signed, yours truley" phrase, followed by "my name isn't" in 1974, that clue? Recently I showed a plausible link between James Hogg's 1824 novel The Suicide's Grave: The Private Memoirs and Confessions of a Justified Sinner and "The Exorcist" movie released in 1973, both of which centered around demonic possession. But what I didn't contemplate at the time of writing, is what triggered the Zodiac Killer to select a portion of The Mikado verse containing the wording "suicide's grave", if indeed it was a deliberate choice for the reasons previously stated. After all, this was a novel released 150 years previously. It goes without saying that the Zodiac Killer often referenced, or was triggered by recent newspaper articles he had read - so the idea of the "suicide's grave" could have germinated in the mind of the Zodiac Killer just before he mailed The Exorcist letter on January 29th 1974. Therefore, what are the odds of the "suicide's grave" being mentioned in the newspapers the day before "The Exorcist" letter was postmarked, that tied into the Japanese themed "The Mikado" (Tit-Willow) and the Asian style characters at the foot of the letter? In total, we would have "The Exorcist" movie and the "suicide's grave" of demonic possession, the Tit-Willow verse from a Japanese satirical comedy, a Japanese relevant newspaper headline on January 28th 1974 referencing the "suicide's grave" of Kao Kang and some Asian symbolism arranged at the bottom of The Exorcist letter. The content in the article below appeared in several newspapers, but this one was published on January 28th 1974, with the inset image (bottom right) from January 26th 1974. They tell of the demise of Kao Kang to his suicide's grave. Kao Kang was a Chinese Communist Party (CCP) leader during the Chinese Civil War and the early years of the People's Republic of China (PRC) before he became the victim of the first major purge within the party since before 1949. The events surrounding Gao's purge, the so-called "Gao Gang Affair". After disagreements with Chairman Mao Zedong, and apparently distraught, Gao Gang (also called Kao Kang) made several attempts to talk to Mao Zedong but was refused an audience with the Chairman. It is possible that Mao avoided facing Gao because of the secret talks between the two men that had prompted Gao's attempts to advance his own position. Gao tried to shoot himself during the February meetings and succeeded in poisoning himself in August 1954. After his suicide, in 1955, Gao was formally expelled from the Party. Gao's ally, Rao, was also expelled from the CCP, and was jailed until his death in 1975. Gao's death not only brought closure of the most immediate sort to the affair but also made sure that he was duly remembered in a dishonorable fashion as a traitor to the party. Wikipedia. Newspapers throughout America in January 1974 covered the re-emergence of Teng Hsiao-ping into the Chinese Politbureau - the man who "wrote the report that sent former State Planner Kao Kang to his siucide's grave" in 1954.(see article above). The Japanese connection to the Zodiac Killer was argued in the article The Suffering Mother Reborn Into Paradise, where it was shown that the phrase "reborn in paradise" from the 408 cipher was a product of Japanese culture and history. This, along with the Zodiac Killer's choice of The Mikado in the Little List letter (July 26th 1970) and The Exorcist letter (January 29th 1974), and the findings presented in this article regarding the "suicide's grave" of Kao Kang, the January coverage of China's sought accord with Japan over the threat from Russia, along with the demonic possession featured in the James Hogg novel (Suicide's Grave) and "The Exorcist" movie, creates a contemporary connection with the past. The Exorcist letter mailed on January 29th 1974 is a curious blend of film and theater, where the Zodiac Killer gives us his opinion on the recent movie The Exorcist (1973) stating "I saw + think "The Exorcist" was the best saterical comidy that I have ever seen", before oddly switching to a small portion of the Tit-Willow verse from The Mikado (1885), adding "Signed, yours truley: He plunged him self into the billowy wave and an echo arose from the sucides grave tit willo tit willo tit willo". One might expect a running theme between the message in "The Exorcist" film and "The Mikado" verse, other than they are two forms of entertainment. Why did the Zodiac Killer choose to blend these seemingly strange bedfellows? The Exorcist movie was about the demonic possession of a young 12-year-old girl and the battle between good and evil, therefore we have to consider a possible connection to this and the chosen phrase from Tit-Willow. The origin of suicide's grave can be found in the then anonymous writings of James Hogg in 1824, a Scottish poet, novelist and essayist who published The Suicide's Grave: The Private Memoirs and Confessions of a Justified Sinner. "The plot concerns Robert Wringhim, a staunch Calvinist who, under the influence of the mysterious Gil-Martin, believes he is guaranteed Salvation and justified in killing those he believes are already damned by God. The novel has been classified among many genres, including gothic novel, psychological mystery, metafiction, satire and the study of totalitarian thought; it can also be thought of as an early example of modern crime fiction in which the story is told, for the most part, from the point of view of its criminal anti-hero. The action of the novel is located in a historically definable Scotland with accurately observed settings, and simultaneously implies a quasi-Christian world of angels, devils, and demonic possession. James Hogg's brief cameo role in the final pages of the novel is effectively his "signature" appended to the otherwise anonymous original publication. Wikipedia. Emma John of The Guardian writes "If you think that the best response to religious extremism is to laugh at it, then James Hogg's most famous work, published in 1824, demands your full attention. A tale of demonic possession, it is also a caustic comedy, skewering the religious bigotry that existed among the era's Scottish Reformers". The James Hogg novel has been described as comedic and satirical in nature, exactly the same as the Zodiac Killer described The Exorcist movie in 1974. Both "The Exorcist" and "The Suicide's Grave" are tales of demonic possession, so was the choice of "Tit-Willow" containing the wording of "Suicide's Grave" from The Mikado (1885), also released in the 19th century, just a fortunate coincidence, or did the Zodiac Killer deliberately create a running theme of demonic possession in his January 29th 1974 letter? The anonymous nature of James Hogg's book and cameo signature appears consistent with the mysterious "Signed, yours truley" adopted by the Zodiac Killer in his letter. The middle section of James Hogg's book is called "The Confession", describing a tale of murder, which portrays Robert Wringhim's descent into madness and believed murder of his brother, George, by stabbing him in the back. Despite being an obvious "clutching at straws", this is reminiscent of "The Confession" letter mailed in 1966 that describes a murderer who declares "I am insane" while stabbing Cheri Jo Bates once in the back.
The Zodiac Killer appeared to be a well-read individual with a penchant for the historical, so was the choice of The Exorcist movie and the "Suicide's Grave" reference another example of look long enough and you will find, or was the Zodiac Killer manufacturing his communications carefully and creatively, with meaning behind his madness? It has previously been shown that the Zodiac Killer designed the April 24th 1978 and May 2nd 1978 letters in response to the Oscars movie ceremony, which was celebrating its 50th Academy Awards of cinematic achievement at the Dorothy Chandler Pavillion in Los Angeles on April 3rd 1978. The Dorothy Chandler Pavillion at North Grand Avenue was situated 4.5 miles from the KHJ-TV Studios at 5615 Melrose Avenue, which was the target of the May 2nd 1978 letter mailed by the Zodiac Killer. But why would the Zodiac Killer choose a seemingly random television station in Los Angeles to deliver his Oscars message, by writing "Hey-you actors-this is your lucky Break. Remember-whoever plays me has his work cut out for him", preceded by the message "I am waiting for a good movie about me" on April 24th 1978? On the eve of the Academy Awards ceremony the KHJ-TV Studios ran its yearly special about the Oscars (voted on by polling), hosted in 1978 by George Hamilton and Brenda Vaccaro. Wayne Thomas joined KHJ-TV Studios as an announcer in 1959 and served for 27 years. The"Your Choice for the Oscars" production was the brainchild of Wayne Thomas, which voted for the best film, best actor and actress, best supporting actor and actress, and best song, spanning six categories. The Zodiac Killer, back with us in 1978 after four years in the wilderness, was clearly yearning attention from the movie industry for his perceived special achievements (or he wanted to make it appear so). The May 2nd 1978 letter would target Pat Boone for his perceived religious zealotry, stating "Pat Boone-his theocratic crap is an obscenity to the rest of the world". He was present at the Oscars watching his daughter, Debby Boone, perform her 1977 hit song "You Light Up My Life", which spent 10 weeks at No 1 on the Billboard Hot 100 chart and won the best original song category at the Academy Awards ceremony. This song was also voted for in the KHJ-TV Studios 2-hour television special. So it's no surprise that the Zodiac Killer wanted to know which actor was going to play him in a "good movie" a few weeks later, hinting at the Academy Awards and stating "I have decided to start killing again-please hold the applause". However, this tactic employed by the Zodiac Killer in 1978 was not the first time he used this methodology of invoking movie award ceremonies in his correspondence, when he mailed the Exorcist letter on January 29th 1974 - effectively binding three consecutive letters under the banner of acting and film awards. One has to ask themselves the question of why did the Zodiac Killer wait from December 26th 1973 (The Exorcist release date) to January 29th 1974, to mail a letter beginning with "I saw + think "The Exorcist" was the best saterical comidy that I have ever seen"? The use of "best satirical comedy" gives the impression of comparison to other movies in a genre, by categorizing The Exorcist into a grouping of comedy films. In other words, it wasn't the best movie, it was the best satirical comedy. The timing of this letter, the Zodiac Killer's use of the word "best", and his propensity to respond to recent newspaper coverage, compelled me to search through newspapers.com in the days leading up to the Exorcist communication, to see what may have inspired the Bay Area murderer to compose this introduction. I didn't have to go far. The Exorcist movie won multiple 31st Golden Globe film awards at the Beverly Hilton, Beverly Hills, California on January 26th 1974 for "Best Film", "Best Director", "Best Supporting Actress" and "Best Screenplay". This was featured in many newspapers, including the Santa Cruz Sentinel and The Sun Times on January 28th 1974. So, it's not difficult to see why the Zodiac Killer mailed the Exorcist letter three days later (January 29th 1974) and began his snarky rebuttal of the film by writing "I saw + think "The Exorcist" was the best saterical comidy". He simply used the newspaper headlines and stories to compose a response to the accolades received by an extremely popular and successful film. His response to the Golden Globe film awards would be replicated after the 50th Academy Awards ceremony on April 3rd 1978, when he mailed the April 24th 1978 and May 2nd 1978 letters, stating "I am waiting for a good movie about me", "Hey-you actors-this is your lucky Break. Remember-whoever plays me has his work cut out for him" and "please hold the applause". This running theme of movie awards present in three consecutive Zodiac Killer communications, that hasn't been spotted by amateur researchers for nearly 50 years, should convince you that one mind was responsible for composing the January 29th 1974, April 24th 1978 and May 2nd 1978 letters. But unfortunately for many it won't. The idea that a hoaxer could have spotted the inspiration for the Exorcist letter and replicated it four years later (in 1978), that no Zodiac researcher has found in nearly half a century, will now be used as a viable explanation. For some, no amount of evidence will shift their belief that the April 24th 1978 letter is a hoax. They will die with this inscription on their tombstone. But hopefully, some people will keep an open mind and consider the possibility that the Zodiac Killer did return in 1978.
In a letter postmarked January 29th 1974, the Zodiac Killer described The Exorcist movie as "the best saterical comidy that I have ever seen". The Exorcist movie, released on December 26th 1973, was directed by William Friedkin. But why did the Zodiac Killer wait just over one month to describe this horror film as a satirical comedy? I suspect that the timing of this communication and the phraseology chosen within it was carefully designed by the Bay Area murderer. This letter was likely mailed in the hope the San Francisco Chronicle would publish the Zodiac Killer's handiwork on January 30th 1974. The day after, the San Francisco Chronicle wrote under the heading "Zodiac Mystery Letter - First Since 1971", "The killer who calls himself Zodiac broke a silence of nearly three years yesterday with a bizarre note to The Chronicle". William Friedkin made his directorial debut in the comedy movie "Good Times" in 1967 starring Sonny Bono and Cher, who appeared as themselves in this musical parody of various genres, including mysteries, westerns, Tarzan movies and spy thrillers. A parody is a creative work designed to imitate, comment on, and/or mock its subject by means of satirical or ironic imitation. The connection between Sonny Bono, Cher and William Friedkin would come full circle in January of 1974, when the Sonny and Cher Comedy Hour on Channel 7 was advertised in many newspapers. The Comedy Hour was to feature a satirical (mocking) presentation of The Exorcist movie by showing the comedic reactions of patrons leaving the cinema. This can be viewed on YouTube. The Sonny and Cher Comedy Hour was an American variety show that starred American pop singers Sonny Bono and Cher, who were married to each other at the time. The show ran on CBS (Columbia Broadcasting System) in the United States, beginning in August 1971. The show was cancelled in May 1974, due to the couple's divorce, but the duo reunited in 1976 in a similarly formatted show. The Sonny and Cher Comedy Hour was due to be aired on Wednesday, January 30th 1974, the exact day the Zodiac Killer had likely hoped his Exorcist letter would be published by the San Francisco Chronicle. So were the words "satirical" and "comedy" deliberately chosen to coincide with this show? I would like to revisit something I've covered previously regarding the Exorcist letter mailed on January 29th 1974 and the "My Name is" letter mailed on April 20th 1970. When the Zodiac Killer designed the Exorcist letter he wrote "signed, yours truley" and then proceeded to paraphrase a verse from Tit-Willow and Gilbert & Sullivan's The Mikado. One would have thought that placing "signed, yours truley" preceding this verse was a prelude to his identity. When we visit the entirety of this act from The Mikado, it becomes apparent that the next line in the verse following what Zodiac quoted is "Now I feel just as sure as I'm sure that my name is(n't) Willow, titwillow, titwillow". In this instance we have a trinity of coincidences, where the Zodiac Killer tempts us with a signature from the verse, from which we can form the sentence of "my name is", that he previously used in his April 20th 1970 letter as an introduction to a mystery 13 symbol code and his name. The Exorcist letter broke with tradition when he used "Me" instead of his crosshairs as an identity, before giving us his running victim total. Bearing in mind the aforementioned correlation between the Exorcist letter and "My Name is" letter, I couldn't help thinking his identity of "Me" would be found in the 13 symbol code using an extremely simplistic method. There is little doubt that the Zodiac Killer knew a 13 character code could not be solved using conventional techniques because of its length, so very likely created something superficial. The fact that this letter was mailed with an AM postmark on the same day the Robert Salem murder broke in the morning edition of the San Francisco Chronicle, with the Zodiac pseudonym scrawled on the wall of the victim's apartment - likely meant that this letter was prepared in haste. A code created this quickly has a high probability of being solved - a code with one repetitive feature of three circled 8's. Using the shift technique the Zodiac Killer employed in the 340 cipher, solved by David Oranchak (USA), Sam Blake (Australia) and Jarl Van Eycke (Belgium) in 2020, I used a period 8 shift in the code to select new characters 8 places to the right. Using a circular shift pattern, the first circled 8 right-shifted to the letter "M", the second circled 8 right-shifted to the letter "E", and the third circled 8 right-shifted to the Zodiac crosshairs, thereby equating the Zodiac Killer's identity to "ME", just as he had done in the Exorcist letter on January 29th 1974. Both of these correspondences tempted us with a name, both communications can be linked to The Mikado and the "my name is" phrase, and the April 20th 1970 code can easily reproduce the "Me" signature present in the Exorcist letter using the standout numerical feature in the code. Another communication, mailed on October 27th 1970, also featured a name synonymous with The Mikado, when the Zodiac Killer wrote *peek-a-boo you are doomed" around the knot-hole of a tree. Peek-a-boo was a character from an 1888 production of The Mikado, entitled The Capitalist. But take a look at the "ME" in the word doomed, in a card that stated "I feel it in my bones, you ache to know my name, and so I'll clue you in." By the way, are the police having a good time with the code? If not, tell them to cheer up; when they do crack it, they will have me.
The following is an amalgamation of previous articles: Six months after the Zodiac Killer's Albany, New York letter and code, another letter would arrive at the San Francisco Chronicle on January 30th 1974. Postmarked the day before (January 29th), this letter was a curious blend of The Exorcist movie (1973) and the comedic opera The Mikado (1885), two productions separated by 88 years. The Zodiac Killer plagiarized The Mikado twice in the July 26th 1970 letter, but this appeared to have some purpose in relation to his hunting activities - that the Zodiac Killer had created a list of potential victims, who he would then kill and ultimately torture in paradise. This seemed at odds with his use of The Mikado in 1974. Any suggestion that the Zodiac Killer was contemplating suicide at this juncture because of his choice of Tit-Willow, appeared to be dashed in the following paragraph when he stated "If I do not see this note in your paper, I will do something nasty, which you know I'm capable of doing". The notion that the Zodiac Killer had reached a watershed moment and was about to ditch the pseudonym he had coveted for so many years, would also be premature, when he mailed the 1978, 1986 and 1987 letters, all containing his infamous introduction of "This is the Zodiac speaking". The 1978 and 1987 letters had one thing in common with the 1974 letter, in that they all carried the wording "yours truly" or "yours truley", followed by a colon. This wording is commonly used before a signature, with the colon used to separate two independent clauses when the second explains or illustrates the first. In the 1978 and 1987 letters the Zodiac Killer follows "yours truly" with "guess", whereas, he inserts the plagiarized verse from Tit-Willow where his signature should be placed in the 1974 Exorcist letter. The primary conclusion to draw from this, is the Zodiac Killer was yet again asking us to "guess" his name through the verse of Tit-Willow. He may have been bluffing, but giving us his first name in such cryptic fashion could never be realistically used as evidence against him, because any conclusions drawn from this verse through subjective interpretation, would never have any standing in a court of law. There are five things in relation to The Exorcist movie and the Tit-Willow verse that point to one name. There is also another that points backwards to the April 20th 1970 letter, when the Zodiac Killer teased us with his name by stating "My name is", followed by a thirteen character code. The Exorcist book was written by William Blatty in 1971, which told the story of a twelve-year-old girl possessed by a powerful demon, that was later adapted by director William Friedkin in the film version released on December 26th 1973. The Tit-Willow verse from The Mikado was created by William Schwenck Gilbert, which contained multiple examples of "Will" and "Bill" within words such as "Willo" and "Billowy" (Will and Bill being short for William). This verse followed The Exorcist introduction and the promise of a signature by use of "yours truley". If we look at the next paragraph in the Tit-Willow verse from the complete version, it reads "Now I feel just as sure as I'm sure that my name Isn't Willow, titwillow, titwillow". Very reminiscent of the "My name is" letter, but in this instance "My name Isn't". Now let us take a look at the final paragraph of the Exorcist letter where he wrote "If I do not see this note in your paper, I will do something nasty, which you know I'm capable of doing". This mirrors his very first communications on July 31st 1969 when he wrote "I want you to print this cipher on your frunt page by Fry Afternoon Aug 1-69, If you do not do this I will go on a kill ram page Fry night that will last the whole week end. I will cruse around and pick of all stray people or coupples that are alone then move on to kill some more untill I have killed over a dozen people". On July 31st 1969 and January 29th 1974, he concluded both correspondences with the threat "to kill" more people if his letters were not published in the newspapers. In his decoded 408 cipher, he wrote "To kill something gives me the most thrilling experence". To the best of my knowledge, this is the only time the Zodiac Killer used the word "something" prior to January 29th 1974 - and used it in reference "to kill something". So, when we look at the final paragraph of the Exorcist letter where he wrote the words "I will do something nasty", it is apparent that "to kill something" was his likely threat. The Zodiac Killer then finished the letter with another puzzle (likely decoded by Kevin Robert Brooks).
Mike Rodelli is convinced that DNA will not solve the Zodiac case because the authenticated letters were not licked by the sender. Mike Rodelli spoke to Alan Keel in 2007, who was a Criminalist at the San Francisco Police Department from 1996 to 1999. He gave Mike Rodelli the following information: "that there were two letters in possession of the department that, in contrast to the "true" Zodiac letters, had abundant saliva and DNA-containing oral epithelial cells on them, that DNA was easily extracted from these two letters, and that the DNA extracted from these two letters matched between them. These two letters were considered forgeries, since the "true" Zodiac verifiable letters had not been licked by the sender". According to Mike, Alan Keel had "analyzed two letters, one of which is the 1978 'forgery', and finds that this letter and one of the 1974 letters are loaded with saliva and cells. He then easily extracts DNA from both of these letters using the more primitive DNA technology of that time and finds that the DNA matches between those two letters, thus proving that one person sent both". On October 29th 2021, Mike Rodelli stated on the Zodiac Killer message board "The fact remains that in 2007 Keel told me, as he had told Lafferty before me, that there is a 1974 forgery based on DNA and the ONLY 1974 letter that had been tested for the presence of cells during Keel's tenure (as demonstrated by the DNA chart that I believe Keel made in about 2000) was the Exorcist letter. This is not rocket science. Even if it is not the Exorcist letter that Keel was talking about, it IS a candidate as being a forgery whose DNA matches the 1978 letter based on the information in the chart". In his book, The Hunt For Zodiac, he stated "Now there was DNA proof that whoever had penned the April 1978 letter had also penned one of the 1974 letters. And apparently it was not Zodiac. According to the chart of DNA testing results compiled by SFPD's lab in ca. 2000, the only one of the 1974 letters that had been tested by Keel up to that time was the January Exorcist letter. This was the letter that had a swarm of palm prints on it. This created an interesting dilemma that lends credence to the possibility that this is a forged letter. Zodiac had penned a dozen letters prior to writing the Exorcist letter and had never left even a single palm print on them. So why had he suddenly and carelessly taken off his glove(s) to write this one and leave a virtual montage of his palms all over it. From that standpoint alone, it makes sense that someone else may have written the Exorcist letter, its bizarre content notwithstanding. While it is possible that one of the other three letters was tested for DNA subsequent to the compilation of the DNA summary chart that Keel had assembled, I believe that on balance the most likely candidate for being the 1974 forgery is the Exorcist letter until proven otherwise". Mike Rodelli is almost certainly correct that the 1974 Exorcist letter is overwhelmingly the most likely DNA match for the 1978 letter (because it was the only tested in the DNA chart), but here is the almost certain proof that neither the 1974 Exorcist or April 1978 letter were forgeries. Take a look at the address style, spacing and handwriting of the Exorcist letter envelope (below), and compare it to the two April 1970 communications (in particular the Dragon Card envelope). These two April 1970 envelopes had not been publicly released by 1974. They were the only confirmed Zodiac communications to use the address style of San Fran (dot) Chronicle prior to January 29th 1974. The January 29th 1974 author (if a hoaxer) could never have produced such similarity, or had knowledge of the address style of the April 1970 communications. But the real Zodiac Killer could have. Mike Rodelli is confident that the SLA letter mailed in 1974 was authored by the Zodiac Killer, stating "Envelopes: This is where the rubber truly meets the road in this discussion and where we can see that it is unlikely that anyone but Zodiac wrote the SLA letter. When you look at the hand printing on the SLA letter in a vacuum, it certainly does not jump off the page to me that it was penned by Zodiac. But when you take a close look at the envelope, that is a different story". Mike then gave me a list of envelopes here, to compare with the SLA envelope. If Mike is confident that these comparisons strongly argue for the SLA letter being Zodiac, there is no way he can argue against the Exorcist letter envelope being the same author as the two April 1970 communications (particularly the Dragon Card). If the two April 1970 communications are genuine Zodiac, then so is the Exorcist letter. If the Exorcist letter is genuine, and the argument in favor of the Exorcist letter DNA matching the 1978 letter DNA by Mike Rodelli is correct, then the 1978 letter is genuine too. In the link above, Mike Rodelli argued that the writing on the SLA envelope is consistent with the Stine envelope, 340 envelope, Bus Bomb envelope and Kathleen Johns envelope, stating "It's hard to look at these envelopes and not see the similarities. And note that the November 8, 1969 envelope contained a piece of Stine's shirt, thus proving its authorship as being from Zodiac. There it is in black and white. So the evidence seems to show that, regardless of the timing and his reason for being in Los Angeles on February 3, 1974 (assuming that the letter was posted from there on that date), it was, in fact, the Zodiac killer who sent the SLA letter, not the SLA itself, which, once again, would not have benefitted from its contents. Nor is there any reason why they would have benefitted from imitating Zodiac's handwriting on the envelope but not attributing the enclosed later to him". Again, if Mike Rodelli is claiming these envelope comparisons are good proof the SLA letter is genuine, he now cannot with any good conscience claim that the comparisons between the Exorcist envelope and the two April 1970 envelopes are not equally as good. Especially when the April 28th 1970 envelope had never been released into the public domain for the author of the Exorcist envelope to copy (not only the handwriting, but the format of San Fran (dot) Chronicle). This being the case, Mike Rodelli (based on his statements) must now accept that the Exorcist letter and SLA letter are genuine Zodiac correspondence. Therefore, if Alan Keel is correct and the 1978 letter DNA matches one of the 1974 communications, we are left with the Badlands card or Red Phantom letter for Mike Rodelli to choose from. But this is what happens to the SLA envelope when we add the "tails" from the Red Phantom envelope. Bearing in mind the SLA envelope wasn't available for the author of the Red Phantom envelope to copy, the writing is virtually indistinguishable from one another, along with a single comma and address format. If Mike Rodelli finds "It hard to look at the envelopes he suggested and not see the similarities to the SLA envelope", he cannot fail to see the similarity between the SLA envelope and Red Phantom envelope. If he believes that the SLA letter was authored by the Zodiac Killer, he now must accept (using his arguments) that the Red Phantom letter was authored by the Zodiac Killer as well. Fortunately, in his book he does. However, in his book Hunt For the Zodiac, he also makes an extended case for the Badlands letter being the Zodiac Killer, stating "In it (the Badlands letter), the anonymous author is accepted based on hand printing as having once again been Zodiac". So, Mike Rodelli is arguing that the SLA letter, Badlands card and Red Phantom letter are genuine Zodiac, but the Exorcist letter is the one he questions most. But if he accepts the arguments he has given for these communications being authentic Zodiac (including the SLA envelope handwriting), he can only come to the conclusion that the Exorcist letter is genuine too. We can therefore conclude, using Mike Rodelli's own words, that if Alan Keel showed a DNA match between the 1978 letter and one of the 1974 letters (and all the 1974 letters are genuine), then the Zodiac Killer licked the envelopes and stamps on the 1978 letter, Exorcist letter, SLA letter, Badlands card and Red Phantom letter. In other words, he never used tap water. The only way that Mike Rodelli can maintain the claims made at the beginning of this article, is to say the comparisons between the two April 1970 envelopes and the Exorcist envelope are not as valid as the comparisons he has made between the SLA envelope and the four envelopes he listed. In good faith, that argument cannot be made. The reality is, that the Exorcist letter is genuine Zodiac correspondence, and contrary to the arguments Mike Rodelli has made.
There are a number of individuals in the Zodiac community who have long vouched for suspects, confident to degrees of near certainty they have found the elusive Bay Area murderer, while simultaneously claiming that the Zodiac Killer was an extremely clever individual, deliberately misspelling his words to misdirect us into believing he had a lower intellectual capacity. Therefore, these individuals should think twice about using the Zodiac communications with unabashed confidence to proclaim their suspect had theatrical leanings, was proficient in mathematics, had a penchant for comics and the movies, or had artistic leanings. A killer who can misdirect by way of spelling mistakes, can easily misdirect by composing three musical numbers from The Mikado, or reference a comic book. The Zodiac Killer could very easily have painted a picture of himself completely antithetical to the person he actually was. So, when somebody arrives at a suspect based on the Zodiac communications, they may want to re-evaluate and consider a suspect completely opposite to the one they have chosen. It is extremely difficult to support the idea of misdirection, only when it suits the conclusions you have already concluded. In other words, a Zodiac Killer who only misdirects when you say so. But did the Zodiac Killer deliberately misspell in his communications? The evidence doesn't support this claim. In an article in the San Francisco Examiner on January 30th 1978 entitled Zodiac:4 Years Later, Sherwood Morrill, a respected documents examiner stated "He is an intelligent guy and we know he deliberately misspells some words because he sometimes spells them correctly". If the Zodiac Killer was intelligent and deliberately misspelling words to misdirect investigators into believing he was less intelligent, why would he spell the word "buttons" in the Dragon card on April 28th 1970 incorrectly, and then nine words later spell it correctly. If the Zodiac Killer was deliberately manufacturing his spelling mistakes, did his attention span falter after only nine words. An intentional and wilful deception would be categorically undermined by such a correction. Twenty-four words later, he would again spell the word incorrectly. This doesn't appear to be an individual achieving a grand deception by constantly fluctuating between good grammar and bad. Three months later, on April 24th 1978, the Zodiac Killer claimed he was now in "control of all things", unlike the Melvin Belli letter when he was afraid he would "loose all controol" and "loose control". Despite the claimed four year hiatus between the January 29th 1974 Exorcist letter and the April 24th 1978 letter, the Zodiac Killer seemingly didn't forget to mail both communications from San Mateo County or Santa Clara County according to the impression given by investigators. Yet he couldn't remember how to incorrectly spell the word "buttons" twice, within a time span of approximately thirty seconds, eight years earlier Mike Rodelli is convinced that DNA will not solve the Zodiac case because the authenticated letters were not licked by the sender. Mike Rodelli spoke to Alan Keel in 2007, who was a Criminalist at the San Francisco Police Department from 1996 to 1999. He gave Mike Rodelli the following information: "that there were two letters in possession of the department that, in contrast to the "true" Zodiac letters, had abundant saliva and DNA-containing oral epithelial cells on them, that DNA was easily extracted from these two letters, and that the DNA extracted from these two letters matched between them. These two letters were considered forgeries, since the "true" Zodiac verifiable letters had not been licked by the sender". According to Mike, Alan Keel had "analyzed two letters, one of which is the 1978 'forgery', and finds that this letter and one of the 1974 letters are loaded with saliva and cells. He then easily extracts DNA from both of these letters using the more primitive DNA technology of that time and finds that the DNA matches between those two letters, thus proving that one person sent both". On October 29th 2021, Mike Rodelli stated on the Zodiac Killer message board "The fact remains that in 2007 Keel told me, as he had told Lafferty before me, that there is a 1974 forgery based on DNA and the ONLY 1974 letter that had been tested for the presence of cells during Keel's tenure (as demonstrated by the DNA chart that I believe Keel made in about 2000) was the Exorcist letter. This is not rocket science. Even if it is not the Exorcist letter that Keel was talking about, it IS a candidate as being a forgery whose DNA matches the 1978 letter based on the information in the chart". In his book, The Hunt For Zodiac, he stated "Now there was DNA proof that whoever had penned the April 1978 letter had also penned one of the 1974 letters. And apparently it was not Zodiac. According to the chart of DNA testing results compiled by SFPD's lab in ca. 2000, the only one of the 1974 letters that had been tested by Keel up to that time was the January Exorcist letter. This was the letter that had a swarm of palm prints on it. This created an interesting dilemma that lends credence to the possibility that this is a forged letter. Zodiac had penned a dozen letters prior to writing the Exorcist letter and had never left even a single palm print on them. So why had he suddenly and carelessly taken off his glove(s) to write this one and leave a virtual montage of his palms all over it. From that standpoint alone, it makes sense that someone else may have written the Exorcist letter, its bizarre content notwithstanding. While it is possible that one of the other three letters was tested for DNA subsequent to the compilation of the DNA summary chart that Keel had assembled, I believe that on balance the most likely candidate for being the 1974 forgery is the Exorcist letter until proven otherwise". Mike Rodelli is almost certainly correct that the 1974 Exorcist letter is overwhelmingly the most likely DNA match for the 1978 letter (because it was the only tested in the DNA chart), but here is the almost certain proof that neither the 1974 Exorcist or April 1978 letter were forgeries. Take a look at the address style, spacing and handwriting of the Exorcist letter envelope (below), and compare it to the two April 1970 communications (in particular the Dragon Card envelope). These two April 1970 envelopes had not been publicly released by 1974. They were the only confirmed Zodiac communications to use the address style of San Fran (dot) Chronicle prior to January 29th 1974. The January 29th 1974 author (if a hoaxer) could never have produced such similarity, or had knowledge of the address style of the April 1970 communications. But the real Zodiac Killer could have. Mike Rodelli is confident that the SLA letter mailed in 1974 was authored by the Zodiac Killer, stating "Envelopes: This is where the rubber truly meets the road in this discussion and where we can see that it is unlikely that anyone but Zodiac wrote the SLA letter. When you look at the hand printing on the SLA letter in a vacuum, it certainly does not jump off the page to me that it was penned by Zodiac. But when you take a close look at the envelope, that is a different story". Mike then gave me a list of envelopes here, to compare with the SLA envelope. If Mike is confident that these comparisons strongly argue for the SLA letter being Zodiac, there is no way he can argue against the Exorcist letter envelope being the same author as the two April 1970 communications (particularly the Dragon Card). If the two April 1970 communications are genuine Zodiac, then so is the Exorcist letter. If the Exorcist letter is genuine, and the argument in favor of the Exorcist letter DNA matching the 1978 letter DNA by Mike Rodelli is correct, then the 1978 letter is genuine too. According to Zodiac researcher Mike Rodelli, criminalist Alan Keel stated that DNA matched between the 1978 letter and one of the 1974 letters (almost certainly the Exorcist letter). It has been shown recently that the Exorcist letter is without doubt authentic Zodiac correspondence, so if Alan Keel is correct, then the 1978 letter is genuine too. We don't actually need the DNA match that has been accredited to Alan Keel, because comparisons between the Melvin Belli letter and 1978 letter, along with the indented writing analysis, is good enough reason to validate the 1978 letter. The one thing we know about the Zodiac Killer was his eagerness to follow the newspaper coverage about his crimes and communications, often responding directly in subsequent letters to the San Francisco Chronicle. Being a narcissist, there is every chance the Zodiac Killer kept news cuttings of his escapades, just like many narcissistic trends on social media today. This may explain why he was able to respond to law enforcement quotes in the newspapers after eight years had passed (unless the following is a coincidence). One such example was the 1986 'Freeway' letter mailed to the San Francisco Chronicle on May 6th 1986. This letter began, "This is the Zodiac speaking. I am still out here and crack proof". This is what Inspector David Toschi stated in the San Francisco Chronicle on April 26th 1978 after the arrival of the latest Zodiac letter. Was the introduction in the 1986 letter a response to Inspector David Toschi after an eight year hiatus? This is what Inspector David Toschi said to the San Francisco Chronicle on August 26th 1976, the same day a Zodiac "Deep Real Estate" advertisement was placed in the personal column of the newspaper. In fact, the 1978 letter may have been a response to the above article, when the Zodiac wrote "Tell herb caen I am here". This excerpt (left) was taken from the San Francisco Chronicle on January 31st 1974 after the arrival of the Exorcist letter two days earlier. It tells you that law enforcement believed the letter was mailed in either San Mateo county or Santa Clara county. Roll forward just over four years later with the arrival of the 1978 letter, that many believed to be an idle and lazy hoaxer who just mimicked the handwriting from previous Zodiac communications. The letter and envelope of the 1978 letter was examined by law enforcement. Here is what was written in the San Francisco Chronicle on April 28th 1978: "Toschi said yesterday that the common, white envelope had no outstanding marks and that the single piece of plain white stationary on which the note was written contained nothing that would give us any indication where he might have gotten it. It was also learned that although the envelope bore a San Francisco postmark, other notations on the cancelation indicated that the letter might have been mailed in San Mateo county or Santa Clara county and was brought here for processing". Law enforcement, at the time, considered this the first contact from the Zodiac Killer since he last wrote the Exorcist letter in January, 1974. If this analysis by law enforcement is correct, then the individual who mailed the 1978 letter, mailed it from the same location as the Exorcist letter, separated by just over four years. They say old habits die hard. The Zodiac Killer is allowed to produce handwriting in subsequent letters the same or similar to previous communications because he is effectively doing no more than mimicking himself. A copycat or hoaxer can mimic the Zodiac Killer using previously published letters and envelopes in the newspapers, but what they cannot do is mimic unreleased communications by the Zodiac Killer. To my knowledge, only two envelopes were released to the newspapers prior to January 29th 1974 that were addressed to San Francisco. The envelope to the Melvin Belli letter was released on December 28th 1969 with the address of "Mr. Melvin M. Belli 1228 Mtgy San Fran Calif". The envelope to the 340 cipher was released on November 16th 1970 with the address of "S.F. Chronicle San Francisco Calif Please Rush to Editor". The author of the Exorcist letter (if a hoaxer) when addressing their envelope to the San Francisco Chronicle only had these two envelopes to work with, but copied neither. This mimicry would have been expected of a hoaxer. Instead, the author of the Exorcist letter chose to mimic part of the address from two envelopes mailed by the Zodiac Killer in April 1970. These two envelopes were addressed San Fran (dot) Chronicle on April 20th and April 28th 1970 and never publicly released via the newspapers prior to January 29th 1974. When you look at the April 28th 1970 envelope in particular, it isn't just the handwriting that is extremely similar, it's the positioning of the detached full-stop, the spacing between each of the three components, the very slight left to right slant, the marginally elevated letter L, the letter I is dotted directly above in every instance, and both the letters R and H are slightly separated. The April 20th and April 28th envelopes were the only two Zodiac communications up to January 29th 1974 that were addressed in this fashion, yet the author of the Exorcist letter (if a hoaxer) would have managed to virtually replicate every facet of this address despite having never laid eyes on them. This clearly shows that the Exorcist letter author was the Zodiac Killer, putting to rest any notion that this letter may have been fraudulent. People will say this just further proves that the Exorcist letter was penned by Inspector David Toschi, who had inside knowledge of the two April 1970 letters. Why would Inspector David Toschi copy the address so perfectly from an envelope that had never been released into the public domain by January 29th 1974, thereby drawing suspicion towards somebody from within? He was an intelligent seasoned investigator, not an imbecile. The exact same reasoning can be applied to the 1978 letter when comparing the opening line from each communication. A copycat or investigator would apply logic, and mimic the widely publicized "This is the Zodiac speaking" introduction displayed in four San Francisco Chronicle publications (or mimic the 11 out of the 12 communications prior to January 29th 1974 that carried this introduction), not mimic an introduction never released into the public domain such as "This is the Zodiac speaking I" in the Melvin Belli letter. However, the Zodiac Killer is perfectly allowed to be himself.
According to Alan Keel, Criminalist at the San Francisco Police Department, San Francisco, California from 1996 to 1999, he "revealed that there were two letters in possession of the department that, in contrast to the "true" Zodiac letters, had abundant saliva and DNA-containing oral epithelial cells on them, that DNA was easily extracted from these two letters, and that the DNA extracted from these two letters matched between them. These two letters were considered forgeries, since the "true" Zodiac verifiable letters had not been licked by the sender". According to Zodiac researcher, Mike Rodelli, Alan Keel had "analyzed two letters, one of which is the 1978 'forgery', and finds that this letter and one of the 1974 letters are loaded with saliva and cells. He then easily extracts DNA from both of these letters using the more primitive DNA technology of that time and finds that the DNA matches between those two letters, thus proving that one person sent both". In Mike Rodelli's latest book In the Shadow of Mount Diablo he makes it obvious that he believes the SLA and Red Phantom letters are communications mailed by the Zodiac Killer. He is also fairly confident that the true Zodiac letters were not licked by the sender. This being the case, then he must accept that the SLA and Red Phantom letters should have no oral epithelial cells on them. The Badlands postcard was pre-stamped, so provided no opportunity for reliable DNA testing. Therefore, the only possible match between the DNA from the 1978 letter and one of the 1974 letters, using Mike Rodelli's thought process, had to be between the 1978 letter and the Exorcist letter. If Alan Keel's claimed statement is correct, then I agree. The problem however, is that the Exorcist letter is almost certainly genuine Zodiac material because of the comparison between its envelope and the unpublished envelopes from April 1970 (which hadn't been published by January 29th 1974). So, if the Exorcist letter is genuine, so is the 1978 letter. If the SLA and Red Phantom letters had been tested and had hypothetically produced a full DNA sample, then Mike would probably agree that the DNA on both letters should have matched (and therefore was secreted from Zodiac). In fact, they couldn't have been tested to produce a full DNA sample, because if they had been authored by the same individual, the 1978 letter would have matched at least two 1974 letters, not one (as apparently claimed by Alan Keel). This is apparent in the DNA chart, that doesn't attribute anything to the Red Phantom letter in comments, and doesn't even include the SLA letter at all. If correct, then the statements of Alan Keel implies that both the 1978 and Exorcist letters have a full DNA profile, which can then be stored and entered into CODIS when required, or used in the science of genetic genealogy. Unless this DNA "print out" has been mislaid or thrown away (which would seem inconceivable), then the profile of these communications can be used, much like Joseph James DeAngelo Jr, to search for any genealogical links that may be relevant to a killer operating in the Bay Area of Northern California.
FOLLOW UP ARTICLES: THE GENETIC IDENTITY OF THE KILLER WE MAY ALREADY HAVE ZODIAC DNA Based on Mike Rodelli's book and everything he has stated over the last few years, we should today have the ability to either incriminate or exclude Kjell Qvale as the Zodiac Killer.once and for all. According to Alan Keel, Criminalist at the San Francisco Police Department, San Francisco, California from 1996 to 1999, he "revealed that there were two letters in possession of the department that, in contrast to the "true" Zodiac letters, had abundant saliva and DNA-containing oral epithelial cells on them, that DNA was easily extracted from these two letters, and that the DNA extracted from these two letters matched between them. These two letters were considered forgeries, since the "true" Zodiac verifiable letters had not been licked by the sender". According to Mike, Alan Keel had "analyzed two letters, one of which is the 1978 'forgery', and finds that this letter and one of the 1974 letters are loaded with saliva and cells. He then easily extracts DNA from both of these letters using the more primitive DNA technology of that time and finds that the DNA matches between those two letters, thus proving that one person sent both". The only problem with the statements by Alan Keel is that the 1978 letter is unlikely to be a forgery. On October 29th 2021, Mike Rodelli stated on the Zodiac Killer message board "The fact remains that in 2007 Keel told me, as he had told Lafferty before me, that there is a 1974 forgery based on DNA and the ONLY 1974 letter that had been tested for the presence of cells during Keel's tenure (as demonstrated by the DNA chart that I believe Keel made in about 2000) was the Exorcist letter. This is not rocket science. Even if it is not the Exorcist letter that Keel was talking about, it IS a candidate as being a forgery whose DNA matches the 1978 letter based on the information in the chart". Mike Rodelli is correct. The only communication from 1974 that can conceivably match the DNA from the 1978 letter is the Exorcist letter. Mike also stated on the Zodiac Killer Net forum "This is where the rubber truly meets the road in this discussion and where we can see that it is unlikely that anyone but Zodiac wrote the SLA letter. When you look at the hand printing on the SLA letter in a vacuum, it certainly does not jump off the page to me that it was penned by Zodiac. But when you take a close look at the envelope, that is a different story". Mike then shows comparisons between the SLA envelope and the Stine envelope, 340 envelope, Bus Bomb envelope and Kathleen Johns envelope, arguing "It's hard to look at these envelopes and not see the similarities. And note that the November 8, 1969 envelope contained a piece of Stine's shirt, thus proving its authorship as being from Zodiac". Therefore, if Mike Rodelli is being fair-minded and believes the SLA handwriting is consistent with these other communications, then he should have no argument conceding that the handwriting and construction of the Exorcist envelope handwriting is consistent with the envelopes from April 20th 1970 and April 28th 1970, which he believes are Zodiac communications. Mike should therefore come to the same conclusion, that since the two April 1970 envelopes were the Zodiac Killer, then so is the Exorcist letter. The April 1970 communications were the only two confirmed Zodiac envelopes to carry the address of San Fran (dot) Chronicle prior to January 29th 1974. The envelopes were also never released into the public domain, meaning the Exorcist letter author could not have mimicked them. Mike should now agree that having established the Exorcist letter as genuine Zodiac material - and using the findings of Alan Keel and Mike's correct argument that the 1978 DNA should conceivably match the Exorcist letter DNA (being the only ones tested in the DNA chart) - we have to conclude that the 1978 letter is genuine as well. Mike went on to say on the Zodiac Killer message board "Keel further allowed, although not in this email but in a conversation I had with him at about the same time, that there was so little saliva on the Zodiac letters that it would not be unfair to say that they had been sealed with tap water and the stamps applied with tap water. So if you're wondering why after 20 years we still don't have a verified sample of Zodiac's DNA it's because the only DNA he may have left on these letters is from when he applied the stamps to the envelopes. If he wet the stamps with water but didn't wear gloves then as he applied the stamps to the envelopes the glue could have pulled a few odd cells off of the tips of his fingers thus leaving essentially touch DNA on the stamps. That is why if they do have Zodiac's DNA today it is because of this minute number of cells that they have had to find using the most Advanced Techniques available". The argument being that the "true Zodiac letters" had few cells, whereas the fraudulent Zodiac letters had "had abundant saliva and DNA-containing oral epithelial cells". However, we have now established that the Exorcist letter is genuine, just like the two April 1970 communications. Yet these two envelopes have few cells found in the DNA chart, whereas the Exorcist letter has abundant cells, despite one author throughout. This disproves the contention of Alan Keel that the 1978 letter is a forgery, that matches one of the 1974 communications. All it proves is that the Zodiac Killer authored the 1978 letter and one of the 1974 communications. These findings also disprove the notion that the Zodiac Killer didn't lick his envelopes and/or stamps. The only way to argue the findings presented above, is to claim that there is unfounded similarity between the Exorcist envelope handwriting and the two April 1970 envelopes, while simultaneously claiming there is a similarity between the SLA envelope and the Stine envelope, 340 envelope, Bus Bomb envelope and Kathleen Johns envelope, But this would be an argument in bad faith. The DNA chart stating that a "DNA sample was obtained" from the 1978 letter appears to back up Mike Rodelli's statement of this letter producing enough DNA to create a profile, based on the findings of Alan Keel. This being the case, if the profile of the 1978 letter matches the profile of the Exorcist letter, then we have a full DNA profile of the Zodiac Killer. Forensic genetic genealogy can now be used to discover the ancestry of the killer and ultimately identify him, in similar fashion to that used in the case of the Golden State Killer, resulting in Joseph James DeAngelo,Jr. pleading guilty to thirteen counts of murder on June 29th 2020 FOLLOW UP ARTICLE: WE ALREADY HAVE ZODIAC DNA Below, on November 16th 1970, is one of the rare times that a Zodiac Killer envelope found itself published in the San Francisco Chronicle. This was the envelope containing the Dripping Pen card and 340 cipher. To this day the vast majority of people believe the Exorcist letter to be a genuine Zodiac communication. If this is the case, then the 1978 letter should also be considered genuine Zodiac material, if you believe the findings of Alan Keel as testified to by Zodiac investigator Mike Rodelli. Alan Keel, Criminalist at the San Francisco Police Department, San Francisco, California from 1996 to 1999 "revealed that there were two letters in possession of the department that, in contrast to the "true" Zodiac letters, had abundant saliva and DNA-containing oral epithelial cells on them, that DNA was easily extracted from these two letters, and that the DNA extracted from these two letters matched between them. These two letters were considered forgeries, since the "true" Zodiac verifiable letters had not been licked by the sender". According to Mike, Alan Keel had "analyzed two letters, one of which is the 1978 'forgery', and finds that this letter and one of the 1974 letters are loaded with saliva and cells. He then easily extracts DNA from both of these letters using the more primitive DNA technology of that time and finds that the DNA matches between those two letters, thus proving that one person sent both". The only two communications tested in the San Francisco Police Department DNA report for cells, from 1974 onwards, were the Exorcist letter and 1978 letter. Therefore, these were the only letters that could reasonably have matched for DNA. Two of the other 1974 communications were not processed for DNA, and the SLA letter wasn't even listed as a "suspected Zodiac correspondence". If Alan Keel believes the 1978 letter to be a "forgery" along with one of the 1974 letters, it is unlikely to be the Exorcist letter. The envelopes of the April 20th 1970 (13-Symbol cipher letter) and April 28th 1970 (Dragon card) were not published in any newspapers. These were the only two confirmed Zodiac envelopes to carry the address of San Fran (dot) Chronicle prior to January 29th 1974. Below is a comparison from these two envelopes and the Exorcist letter. The author of the Exorcist letter (if a hoaxer) had the option to copy the envelope published in the San Francisco Chronicle on November 16th 1970, but chose not to. The handwriting, spacing and composition almost certainly suggests one author. If you believe that the April 20th 1970 and April 28th 1970 letters to be the Zodiac Killer, then it's reasonable to conclude the Exorcist letter (and envelope) was composed by the Zodiac Killer as well. If we arrive at the conclusion that the Exorcist letter is genuine based on the above comparisons, and dismiss the SLA & Red Phantom letters as having nothing to do with the Zodiac case based on findings previously shown on this website, then one has to conclude (if Alan Keel is correct) that the DNA from the 1978 letter must match the DNA from the Badlands/Citizen card. But this seemingly wasn't tested for cells in the DNA chart. If the DNA from the 1978 letter (claimed as a forgery) somehow matched either the SLA or Red Phantom letter, then we would have to rule out both the SLA and Red Phantom letters because their envelopes were written by the same author (see below). Mike Rodelli has argued to the SLA letter (and envelope} being authored by the Zodiac Killer based on handwriting. If he is an advocate for handwriting analysis, then he should come to the conclusion that the SLA & Red Phantom envelopes were written by one author (since neither were published in the newspapers). The SLA & Red Phantom envelopes would also contain the same DNA profile. This being the case, along with the comparisons above suggesting the Exorcist letter is genuine, leaves only the Badlands/Citizen card to match in DNA with the 1978 letter (because only one 1974 letter matched with the 1978 letter). But again, this wasn't tested in the DNA chart. The claim of Alan Keel (assuming this is correct) "that the DNA extracted from two letters matched in DNA", can now produce only one possibility. If the DNA from the 1978 letter matched the Red Phantom letter, then the SLA letter can be ruled out also (this would effectively be three matches). If the DNA from the 1978 letter matched the SLA letter, then the Red Phantom letter can similarly be ruled out.
Therefore, if only two letters matched in DNA, the only possible option is the Exorcist letter and 1978 letter, making both genuine Zodiac communications. Especially when you consider the Exorcist letter was the only communication processed for DNA (and cells were found). This suggests that Zodiac did lick his envelopes and/or stamps. It also suggests that David Toschi is not responsible for writing the 1978 letter, because if he did, he would also be the author of the Exorcist letter, April 20th 1970 letter and April 28th 1970 letter, based on the argument of Alan Keel and the findings above. |
