The wording of "I saw and think "The Exorcist" was the best saterical comidy" in the January 29th 1974 letter was an immediate response to the movie winning four Golden Globes on January 26th 1974, receiving the awards for "Best Film", "Best Director", "Best Supporting Actress" and "Best Screenplay". The wording of "I am waiting for a good movie about me" in the April 24th 1978 letter was a belated response to the April 3rd 1978 Academy Awards (as was the Channel 9 letter on May 2nd 1978). Both of these letters on January 29th 1974 and April 24th 1978 were intrinsically bound to the movie industry, and both carried the Jack the Ripper style valediction of "yours truly", in the form of "yours truley" in 1974 (which was spelled incorrectly) and "yours truly" in 1978 (which was spelled correctly). This form of valediction is clearly not appropriate in the context of a threatening letter, so the use of this "act of farewell" is relatively unusual in this respect.

​Therefore, I looked for something on TV or in the movies that contained both elements of "Jack the Ripper" and "Yours Truly", and found the 1943 short story by Robert Bloch, subsequently made into a fifty minute TV thriller in 1961 entitled "Yours Truly, Jack the Ripper", hosted by Boris Karloff and starring John Williams, Donald Woods and Edmon Ryan. On the Internet Movie Database it is described as follows: "70 years after the Jack the Ripper killings in London, Sir Guy tries to convince the police that Jack may still be alive, eternally young, and still killing, currently in New York". After a  hiatus of several years, Jack the Ripper had returned to begin killing again in New York. 

The same has been argued in the Zodiac case, where the Bay Area murderer appeared to take a hiatus from 1971 to 1974 and returned with the Exorcist letter on January 29th 1974. The same can be said of his inactivity between 1974 and 1978, when he returned to mail the 1978 letter with the introduction "I am back with you". So it is noteworthy that he appeared to use the "yours truly" valediction from the book and TV episode of ​"Yours Truly, Jack the Ripper", which presented the story of a killer returning after a period of inactivity. 

​Another interesting feature of the Exorcist letter was the final paragraph where the Zodiac wrote "Ps. If I do not see this note in your paper, I will do something nasty, which you know I'm capable of doing". You will notice that he described the communication as a "note" and not a letter. Bearing in mind that the TV episode of "Yours Truly, Jack the Ripper" featured Jack the Ripper taking his crimes from Whitechapel in London to New York, I looked for a Jack the Ripper "note" mailed in New York on the date of January 29th. A search of the newspaper archives didn't disappoint. The following newspaper article (among many) describes a "Jack the Ripper in New York", who wrote a "note" to Police Captain Ryan on January 29th 1889 promising that the streets of his precinct would soon be filled with murdered women.

In an odd turn of events, the script of "Yours Truly, Jack the Ripper" may have been turned on its head by the Bay Area murderer, because the previous letter claimed to have been mailed from the Zodiac Killer was postmarked August 1st 1973 from Albany, New York, six months before the arrival of the Exorcist letter on January 29th 1974. The letter, addressed to the Albany Times Union newspaper, stated he was "going to start killing again".

Robert Bloch, the author of "Yours Truly, Jack the Ripper" also wrote "The Thing" in 1932 and "Psycho" in 1959, the latter of which the Zodiac Killer featured in his 148 character cipher and letter in the middle of 1971. The 1971 letter stated that he would "skin 3 little kids and make a suit from the skin" if his cipher was not printed on the front page of the newspaper. This phraseology was reminscent of the murderer Edward Gein, who professed a desire to make a "skin suit" from his dead mother, and the movie "Psycho" that hit cinema screens in 1960 and featured the seated corpse of Norman Bates' dead mother. An arguable case can be made for Robert Bloch inspired letters from 1971 through to 1974, whether one was intended or not.

On January 19th 1889, ten days before the Jack the Ripper "note" on January 29th 1889, it is likely that the same individual first announced his presence to Captain Ryan in a letter (described in the newspaper cutting below), by stating "Do you think that Jack the Ripper is in England?", before promising to kill by next Thursday and signing it with the familiar valediction of "Yours truly, Jack the Ripper".

​CONNECTING RIVERSIDE TO THE ZODIAC USING JACK THE RIPPER [IN 6 PARTS]

It is no coincidence that the April 24th 1978 letter stated "I am waiting for a good movie about me. Who will play me" just three weeks after the 50th Academy Awards ceremony at the Dorothy Chandler Pavillion in Los Angeles on April 3rd 1978, and was followed by a second communication on May 2nd 1978 stating "Hey-you actors-this is your lucky Break. Remember-whoever plays me has his work cut out for him" and "​please hold the applause". The May communication having been mailed to the KHJ-TV Studios in Los Angeles after they ran a public voting poll on the eve of the ceremony (April 2nd 1978) on who their viewers thought would win certain categories at the Academy Awards. A ceremony where the Oscar winning song "You Light Up My Life" was sung at the ceremony by Debby Boone, whose father Pat Boone was threatened in the May 2nd 1978 letter.

​These two letters came four years after the last Zodiac letter arrived on January 29th 1974, which stated "I saw + think "The Exorcist" was the best saterical comidy", three days after the 31st Golden Globe film awards at the Beverly Hilton, Beverly Hills, California on January 26th 1974, in which "The Exorcist" film won "Best Film", "Best Director", "Best Supporting Actress" and "Best Screenplay". Three consecutive communications that just happened to piggyback off award ceremonies for the film industry, that were all presumably conceived and written by Inspector David Toschi and/or Robert Graysmith according to some. If Inspector David Toschi wrote the April 24th 1978 letter, then he probably wrote all three of these letters, and had a hand in the phone call 42 days before the "I am back with you" letter, when somebody rang an individual living in the Mission District and stated "This is the Zodiac. Tell the press that I am back in San Francisco". ​

​Then we have the consistency of language between the April 24th 1978, May 2nd 1978 and July 19th 1978 letters, with all three using the verb "play" and the singular pronoun "me" in the same sentence. Only the first letter being published in the newspapers. They read "I am waiting for a good movie about me. Who will play me" (04/24/78), "whoever plays me has his work cut out for him" (05/02/78} and "Maybe you play chess with me" (07/19/78). The third author could not have copied the second author if different individuals, but they could have been the same person.

If the author of the January 29th 1974 (Exorcist), April 24th 1978 and May 2nd 1978 letters is one person (linked through a film industry theme), then where does that leave us with the July 19th 1978 letter, which has a common theme with both the April 24th 1978 and May 2nd 1978 letters? The author of the July 19th 1978 letter could have borrowed wording from the published April 24th 1978 letter, however, they did manage to continue the consistency in language used in the May 2nd 1978 letter, which they could never have seen if not the same person. The author on May 2nd 1978 and July 19th 1978, on both occasions, opted to mimic the verb "play" and singular pronoun "me" in the same sentence, from the April 24th 1978 letter. That probably leaves one author responsible for the last two letters. And if the May 2nd 1978 letter is linked by one theme to the January 29th 1974 and April 24th 1978 letters, then the July 19th 1978 letter is probably genuine too.

​This consistency, now seen through four communications, would be implicating Inspector David Toschi in a much bigger hoax, who would have also investigated the "I am back in San Francisco" phone call on March 13th 1978 and then mailed the "I am back with you" letter the following month. Additionally, it could open the door to the similarities shown between the April 24th 1978 and Melvin Belli letters. Either David Toschi has played a leading role in fabricating many Zodiac communications, or he is responsible for none. The obvious choice seems to be none. Inspector David Toschi was a busy man, unlikely to be scouring the newspapers for Academy Award and Golden Globe ceremonies, KHJ-TV Studios polls and the World Chess Championships, to create common themes in order to manufacture an elaborate hoax. But there was one man that seemed to find the time. Bearing in mind that the author of the April 24th 1978 letter wrote "I am waiting for a good movie about me. Who will play me", it was quite ironical that the winner for best film in 1978 at the Academy Awards was a "satirical comedy", claimed by some to be semi-autobiographical about the life of "Allen". Woody Allen that is. The film was "Annie Hall", winner of four Academy Awards, not unlike "The Exorcist" movie, which won four Golden Globes on January 26th 1974  

We know that the Zodiac Killer was prepared to link himself to many murders with little to no evidence that vindicated his claims, such as Donna Lass, Kathie Snoozy and Debra Furlong, Cheri Jo Bates, Richard Radetich and the Atlanta Child murders. Law enforcement claimed that they had received dozens of hoax Zodiac letters by the end of 1970, which they obviously classified as such, based on nothing more than handwriting analysis and gut feelings, resulting in the loss of many communications that could have shed greater light on the Zodiac Killer mystery. Unfortunately, this method of determining authentic and inauthentic letters in the Zodiac case still persists 54 years later, with individuals that currently have the ability to spot fake Zodiac letters by the shape of the writing and the tone of a letter. But don't expect this quackery to change.

I mention this as a cautionary warning in regards to the perceived gaps in Zodiac Killer activity, such as the widely touted 4-year hiatus in Zodiac communications between 1974 and 1978. It's one thing believing a letter hasn't met the threshold of evidence to declare its authenticity, but quite another claiming it's a hoax based on nothing more than looking at it. With that said, I will continue the following observations based upon the April 24th 1978 and May 2nd 1978 letters being genuine Zodiac material, because the evidence against is practically zero compared to the evidence for. 

The Hillside Strangler murders, eventually discovered to be both Kenneth Bianci and Angelo Buono Jr., took place in Los Angeles between October 1977 and February 1978, resulting in the murder of ten women and girls who were abducted, raped and tortured. The Hillside Strangler murders took the police far afield, with their investigation spreading to New York and the United Kingdom in pursuit of the killer/s identity, unsure of whether more than one individual was involved in the horrific crimes. One person in 1978 would have had a keen interest in the unfolding newspaper coverage, which makes a multiple page letter mailed to police in respect to this case in January 1978, very interesting. On December 7th 1969, the Zodiac Killer mailed a letter from Fairfield threatening to kill a cop, which after he would turn himself in. On January 19th 1978, Los Angeles Chief Daryl Gates held a news conference on television and stated "The fact we have not had any more murders in the last five weeks suggests that the individual or individuals are not operating. Hopefully that will continue to be the situation. I'm hopeful the killer or killers will come forward and talk with us and give themselves up". Daryl Gates informed reporters that the manhunt was the biggest since the Tate-LaBianca murders which cost 500, 000 dollars.       

Later that day a letter was mailed to Mayor Tom Bradley, with portions of the text released by Chief Daryl Gates. The letter, handwritten and several pages long, stated he was very sick and claimed he had killed his mother, writing "My mother told me to kill those bad and evil ladys", and offering to turn himself in, along with "a friend". The author of the letter also promised to mail an article of clothing from one of the victims to prove the authenticity of the claims.

The Zodiac Killer would apparently reappear on March 13th 1978 and April 24th 1978 stating "This is the Zodiac. Tell the press that I am back in San Francisco" and "I am back with you", before mailing another letter from Los Angeles threatening to kill five people, in which Chief Daryl Gates was number one on that list, with former Los Angeles Chief Ed Davis second. Susan Atkins, part of the Manson family responsible for the Tate-LaBianca murders, was also mentioned fifth on the list mailed to the KHJ-TV studios. As such, we have a letter postmarked January 19th 1978 promising proof to the claims of murder and offering to give himself (and "a friend") up to police, in response to a news conference hosted by Chief Daryl Gates, who asked the killer or killers to give themselves up - followed by another letter mailed from Los Angeles on May 2nd 1978 threatening Chief Daryl Gates, who spearheaded the Hillside Strangler investigation. Who knows whether this was the Zodiac Killer interjecting himself into another major investigation, but it's certainly a possibility.       

Recently it was shown how the Zodiac Killer responded to 31st Golden Globe film awards at the Beverly Hilton, Beverly Hills, California on January 26th 1974, by mailing the Exorcist letter on January 29th 1974, and reacted to 50th Academy Awards ceremony at the Dorothy Chandler Pavillion in Los Angeles on April 3rd 1978, by mailing the April 24th 1978 and May 2nd 1978 letters (the latter mailed from Los Angeles). See here. Two and a half months later, a questionable "Zodiac Killer" letter would be mailed from Los Angeles to the San Francisco Chronicle on July 19th 1978. This communication may also have been partly influenced by a big event. The culmination of the letter read "But maybe you play chess with me. I have several cheap sets in closets all over. I have my name on the bottom of the lid with the scotch tape....My tape is waiting for me all over California".

I have previously suggested that this section of the letter may have been poking fun at David Toschi, who had recently been demoted to "pawn" detail after suggestions he may have been the author of the 1978 letter. However, based on the Zodiac Killer's propensity to infuse recent newspaper articles into his wording, I looked for the keyword "chess" in the days prior to the July 19th 1978 letter. On July 18th 1978, the Santa Cruz Sentinel (and numerous others), reported on the opening game in the World Chess Championship between Anatoly Karpov and Viktor Korchnoi in the Philippines. And chess was a big thing in the 1970s. But the Santa Cruz Sentinel coverage had one peculiar aspect - it carried the headline "Korchnoi, Karpov Play To Draw" alongside another article entitled "SF Chief Says Inspector Didn't Write Zodiac Letter". Could the Zodiac Killer (or impostor) have read the two articles and coalesced them both into his July 19th 1978 letter, the following day. The Santa Cruz Sentinel article also mentioned that David Toschi had been "transferred from the homicide squad to the pawn shop detail last week". Therefore, we have the mention of "pawn detail", "chess" and David Toschi alongside each other, on the same page.       

The whole letter read "I am the ZODIAC and I am in control of all things. I am going to tell you a secret. I like friction tape. I like to have it around in case I need to truss someone up in a hurry....I have my real name on a small metallic tape. You see, while you have it in your possession, I want you to know it belongs to me and you think I may have left it accidentally. I am athletic. It could be swim fins, or a piece of scuba gear. But maybe you play chess with me. I have several cheap sets in closets all over. I have my name on the bottom of the lid with the scotch tape....My tape is waiting for me all over California. Do you know me? I am the ZODIAC and I am in control". 

I noticed that the author used "My tape is waiting for me all over California" and "I have cheap sets in closets all over", suggesting that his "cheap chess sets" and "tape" were maybe in the same locations or relevant to one another. The author also stated that "I have my name on the bottom of the lid with the scotch tape" - and we know a chess case or chess box has a lid. Was the author suggesting that he could play David Toschi at chess anywhere in California, now that he was reported in the newspapers to be "vacationing at an undisclosed location"? In a previous article (linked above), a common theme was shown between the January 29th 1974, April 24th 1978 and May 2nd 1978 letters through the film industry, so could any common verbiage be unearthed between the consecutive May and July letters mailed from Los Angeles, bearing in mind the May letter wasn't released to the public. On May 2nd 1978, the Zodiac Killer wrote in respect to the film industry "whoever plays me has his work cut out for him", while the following July 19th 1978 letter stated "But maybe you play chess with me". The two phrases of "plays me" and "play chess with me" both used in respect to another participant. It's not compelling, only noteworthy.  

The Zodiac Killer would shape his communications around previous newspaper articles - and I noticed that the author of the July 19th 1978 letter used the phrase "I am in control" at the beginning and end of the letter, rather than "I am now in control" that was used at the end of the April 24th 1978 communication. This meant that the author of the July 19th 1978 letter could have altered the wording to mimic the misquoted phrase used in some newspaper articles in April, such as the Atlanta Journal shown above. Was this the Zodiac Killer reaffirming to the public what he had read in the newspapers, or somebody simply misquoting or deliberately changing the wording of the Zodiac Killer? The April 24th 1978, May 2nd 1978 and July 19th 1978 letters all had one common theme, with only the first letter being published in the newspapers. They read "I am waiting for a good movie about me. Who will play me" (04/24/78), "whoever plays me has his work cut out for him" (05/02/78} and "Maybe you play chess with me" (07/19/78). All three used the verb "play" and the singular pronoun "me" in the same sentence. The third author could not have copied the second author if different individuals, but they could have been the same person. If the author of the January 29th 1974 (Exorcist), April 24th 1978 and May 2nd 1978 letters is one person (linked through a film industry theme), then where does that leave us with the July 19th 1978 letter, which has a common theme with both the April 24th 1978 and May 2nd 1978 letters? The author of the July 19th 1978 letter could have borrowed wording from the published April 24th 1978 letter, however, they did manage to continue the consistency in language used in the May 2nd 1978 letter, which they could never have seen if not the same person. The author on May 2nd 1978 and July 19th 1978, on both occasions, opted to mimic the verb "play" and singular pronoun "me" in the same sentence, from the April 24th 1978 letter. That probably leaves one author responsible for the last two letters. And if the May 2nd 1978 letter is genuine Zodiac material, then the July 19th 1978 letter probably is too. 
​
APRIL 24TH 1978: "I am waiting for a good movie about me. Who will play me".
MAY 2ND 1978: "Whoever plays me has his work cut out for him". (unpublished)
JULY 19TH 1978: "Maybe you play chess with me". (unpublished)

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 that opened with the words "Dear Channel Nine".

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 on Channel 9. 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 "Channel 9" 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.

You may be wondering why the Zodiac Killer mailed the April 24th 1978 letter with the statement "I am waiting for a good movie about me" - and then possibly - followed this up with a mailing on May 2nd 1978 to KHJ-TV Studios in Los Angeles, writing "Hey-you actors-this is your lucky Break. Remember-whoever plays me has his work cut out for him". We know that most Zodiac Killer correspondence had purpose, by taking something he had read in the newspapers and incorporating it into his letters. The year 1978 was a special occasion for the Oscars because it was celebrating its 50th Academy Awards ceremony 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 Three and four weeks later, the two above communications arrived mentioning "actors" and "movies", with the second letter addressed to Los Angeles.​

Debby Boone became a household name with her 1977 hit song "You Light Up My Life", which spent 10 weeks at No 1 on the Billboard Hot 100 chart. The song won the Oscar for Best Original Song, which she performed at the 1978 Academy Awards ceremony. Debby Boone was the daughter of actor-singer Pat Boone, who was threatened as a third target by the "Zodiac Killer" in the May 2nd 1978 letter, when he wrote "Pat Boone-his theocratic crap is an obscenity to the rest of the world". Pat Boone was present at the awards ceremony. Therefore, we can connect "actor" Pat Boone in the letter, to the Academy Awards ceremony of "actors", through his daughter. But why would the "Zodiac Killer" choose KHJ-TV Studios​ to mail his correspondence? 

​Wayne Thomas joined KHJ-TV Studios as an announcer in 1959 and served for 27 years. He created a show on the eve of the Oscars called "Your Choice for the Oscars", in which public polling decided upon the nominations in six categories. On the eve of the 50th Academy Awards ceremony, the predicted awards by KHJ-TV were John Travolta, Jane Fonda, Star Wars, Melinds Dillon, Alec Guiness and the song "You Light Up My Life" (sung at the ceremony by Debby Boone). This now binds Pat Boone, KHJ-TV and the Oscars into one neat bundle. So it's no surprise that the "Zodiac Killer" wanted to know which actor was going to play him in a movie a few weeks later, hinting at the Academy Awards and stating "I have decided to start killing again-please hold the applause". Two months prior to the May 2nd 1978 letter, in which the "Zodiac Killer" targeted "Ex Chief piggy Ed Davis" as his second potential victim, the once Los Angeles police chief (turned politician) spoke with KHJ-TV interviewers Ann Kesner and Nathan Roberts about his reputation as "the marshal from Dodge City who will make this a safe state".

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. 

Forty-two days before the mailing of the April 24th 1978 letter which stated "I am back with you. Tell herb caen I am here", somebody made a telephone call on March 13th 1978 to an individual in the Mission District proclaiming "This is the Zodiac. Tell the press that I am back in San Francisco". The obvious similarities in the language indicates there could be one individual responsible for both messages. The person who received the telephone call is unlikely to be some random member of the public, but somebody relevant to the Zodiac Killer case who lived in the Mission District in 1978 and had some influence in passing on the message. It could be somebody in the media or somebody connected to law enforcement, so if anybody can offer a suggestion please post it on any relevant Zodiac forum. The incident was obviously taken seriously because it was personally investigated by Inspector David Toschi - and if not reported in the newspapers - made the mention of David Toschi in the 1978 letter even more curious, in accompaniment to the use of "I am back" in both messages, along with "Tell the press" and "Tell herb caen".

This phone call was captured as a recording on a voice answering machine, but I suspect it was routinely dismissed as a hoax as many phone calls had been previously and likely lost to the hands of time, despite no evidence for such a conclusion. Much evidence has fell by the wayside through incompetence and lethargy in the Zodiac case, and this phone call is just another example of a missed opportunity.

On May 5th 1978, just 11 days after the "I am back with you" letter, somebody claiming to be the Zodiac Killer phoned the San Mateo Police Department and falsely reported that a bomb had been placed in the Transamerica Pyramid at 600 Montgomery Street. This too had a loose connection to the 1978 letter, which mimicked the Melvin Belli letter mailed on December 20th 1969. Both the 1978 and Melvin Belli letter began the introduction with "This is the Zodiac speaking I", which were not only grammatically incorrect in both instances by failing to punctuate between "speaking" and "I", but were the only two communications to date that didn't keep the "This is the Zodiac speaking" introduction exclusively on one line. Something a copycat would have been expected to do, had he copied at least four Zodiac letters published in the newspapers. The 1978 and Melvin Belli letters also inversely mimicked each other by the use of  "I can not remain in control for much longer" in 1969 (one example) and "I am now in control of all things" in 1978. Bearing in mind these comparisons between the two letters - and the Melvin Belli letter was mailed to 1228 Montgomery Street in San Francisco - it is unusual that the telephone threat on May 5th 1978 was directed against the Transamerica Pyramid at 600 Montgomery Street, just 600 meters south of the Belli residence. The law offices of Melvin Belli at 722 Montgomery Street, purchased in 1959, were even closer to the Transamerica Pyramid at a mere 100 meters.

​It should also be noted that the 1978 letter was thought to have been mailed in either San Mateo or Santa Clara County, just like the Exorcist letter on January 29th 1974. On April 28th 1978, the Chronicle reported that "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". The threat towards the Transamerica Pyramid was phoned into the San Mateo Police Department.  

When the Zodiac Killer last claimed he was to plant a bomb on June 26th 1970, he utilized the peak of Mount Diablo on the eastern side of San Francisco Bay in Contra Costa County, which dominated the skyline at 3,849 feet. When the Transamerica Pyramid was completed in 1972 it was the tallest building in San Francisco, with an elevation of 853 feet. Would it really be a surprise if the Zodiac Killer had chosen the two most prominent landmarks on the San Francisco Bay Area skyline to threaten its residents with bombs? The Transamerica Pyramid would also feature in the 2007 Zodiac film directed by David Fincher, shown in time lapse photography to depict the transition of time between Zodiac events.

However, this wasn't the only similarity between the Melvin Belli letter and 1978 letter. Not once, in any of the widely touted list of authenticated Zodiac Killer communications from July 31st 1969 to January 29th 1974, did the killer ever cross out a spelling mistake (or otherwise) with a straight line (he blacked out errors). The Badlands card (not authenticated) on May 8th 1974 did scruffily cross out the misspelling of consternation, but failed in any capacity to identify its sender, such as the Zodiac introduction or his crosshairs. 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. Not only did the 1978 letter carry the identical introduction and punctuation error as the Melvin Belli letter, as well as being very deliberately and carefully written, but both inserted an unrequired word into the message before crossing it out, despite it being spelled correctly thus far. These are the only two communications up to April 24th 1978 that carried both of these features. 

When we look at the similarities between the Melvin Belli letter and 1978 letter described above, we also have to note that the 1978 letter was specifically using language adopted from the Belli letter when stating "I am now in control of all things". Just over eight years earlier, the Belli letter stated  "I will loose control again and take my nineth & possibly tenth victom" and "I will loose all controol of my self & set the bomb up. Please help me I can not remain in control for much longer". Therefore, the introduction similarity of "This is the Zodiac speaking I" between the two letters ​(with grammatical error), and the crossed out wording only existing in these two letters up to April 24th 1978, in all likelihood influenced the author of the 1978 letter when designing this latest correspondence. The introduction, the correction technique, and the use of the word "control" regarding the Zodiac Killer's mindset were unique only to these two letters up to April 24th 1978. 

Exactly one year before the murder of Paul Stine in Presidio Heights, Melvin Belli appeared in an episode of Star Trek on October 11th 1968 entitled "And the Children Shall Lead", playing the character Gorgan. When referencing the Melvin Belli letter in 1978, the Zodiac Killer stated "I am waiting for a good movie about me. Who will play me". 

Excerpt from Wikipedia on And the Children Shall Lead: "The federation starship Enterprise arrives at the planet Triacus. Captain Kirk, Dr. McCoy, and First Officer Spock beam down in time to witness the death of Professor Starnes, the leader of a scientific expedition team. The other members of the expedition, apart from their five seemingly unconcerned children, seem to have died at their own hands. The crew bring the children back to the Enterprise, where McCoy evaluates them and determines that they are suffering from lacunar amnesia, unaware of what happened to their parents and unable to grieve. However, when left unattended in one of the ship's rooms, the children chant an evocation and summon a glowing humanoid named Gorgan. He advises them to take control of the crew in order to get to Marcus XII, his preferred destination. The eldest child, Tommy, uses mental powers Gorgan has bestowed on the children to trick the crew into steering the ship while presenting illusions that make them think they are still in orbit above Triacus. Upon reviewing a troubling expedition film recorded by Starnes, Spock, McCoy, and Kirk return to the bridge to find the children and Gorgan fully in control of the crew. Unable to break their hold on the crew, Spock observes that the children are merely possessed by Gorgan, who must be the evil embodiment of an ancient group of space-warring marauders released by Starnes's archaeological survey".

1978 letter: "I am now in control of all things". ​

The 1998 San Francisco Police Department DNA chart of suspected Zodiac correspondence shows that DNA was obtained from the 1978 letter, but it was deemed not authentic. If we believe that investigators correctly cleared Inspector David Toschi of any wrongdoing in the manufacture of the 1978 letter, then it is hard to argue against this communication being created by the same individual who mailed the 1969 Melvin Belli letter, with added shirt piece from the Paul Stine murder. The Zodiac speaking introduction with grammatical error on the opening line and the correction technique employed in the 1978 letter, which mimicked the Melvin Belli letter from 1969 (allied to the use of "control" in both communications), could only have been reasonably crafted by one person. If it wasn't David Toschi who wrote the 1978 letter, there is a good chance it was the Zodiac Killer. The DNA obtained from the 1978 letter has already ruled out both Arthur Leigh Allen and Lawrence Kane many years ago. The 1978 letter being genuine would also rule out Ross Sullivan, who died in 1977. If David Toschi didn't author the 1978 letter, then a fresh examination of this letter using more advanced DNA recovery should be a priority.
​ 
THE "I AM BACK" PHONE CALL - MARCH 13TH 1978

It has regularly been stated that there was an approximate four year hiatus in Zodiac communications from 1974 to the arrival of the "I am back with you" letter on April 24th 1978. If you believe in this 4 year absence of Zodiac communications, then the following information from page 204 of Robert Graysmith's Zodiac paperback book should be of interest. Despite Robert Graysmith often playing loose with the facts of this case, the following information within his book concerns Inspector David Toschi directly.

​It stated that on March 13th 1978 at 2300 hours (just over a month before the "I am back with you" letter) somebody made a sinister phone call to an individual living in the Mission District of San Francisco, whose home voice recorder had stored the message. Apparently David Toschi responded to this incident. When played, the message read "This is the Zodiac. Tell the press that I am back in San Francisco". The reportee stated he has no idea why the call came to him. Over four years had elapsed since the January 29th 1974 Exorcist letter, yet here we have a malicious phone call from somebody claiming to be Zodiac with the words "I am back", just over a month before the April 24th 1978 letter mailed to the San Francisco Chronicle stating "I am back with you". Another comparison between the two is "Tell the press that I am back" and "Tell herb caen I am here". Both concerning the newspapers. Herb Caen was a San Francisco humorist and journalist whose daily column ran in the San Francisco Chronicle for nearly sixty years. 

Would Inspector David Toschi seriously listen to a sinister voice recording with these words, then fashion a hoax letter 42 days later using the same phraseology, while inserting the wording "That city pig toschi is good". While possible, it seems wholly implausible. After four years of perceived inactivity, what is the likelihood that the San Francisco voice recording and letter are two separate individuals perpetrating a hoax with identical wording, within a month and a half of one another? As with the Oklahoma radio station recording of an individual claiming to be Zodiac, I suspect this recording was also summarily dismissed as a hoax and lost to the hands of time. I am not suggesting it was the real Zodiac Killer, but losing or tossing away potential evidence that may later gain significance, should be avoided. This voice recording may have seemed unimportant on March 13th 1978, but less so on April 24th 1978.

​On May 5th 1978, just 11 days after the "I am back with you" letter, somebody claiming to be the Zodiac Killer phoned the San Mateo Police Department and falsely reported that a bomb had been set in the Transamerica building at 600 Montgomery Street (the same street of Melvin Belli's residence in 1969). Although it is difficult to separate the hoaxers from the real Zodiac Killer, we do have the common phraseology in the voice recording and letter on March 13th and April 24th 1978, that while not compelling, is nonetheless interesting.  

THE THREAT ON THE TRANSAMERICA PYRAMID 

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.

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 to compare with the SLA envelope. If Mike is confident that these comparisons strongly argue for the SLA letter being Zodiac, then 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.   

On January 29th 1974, a letter was mailed from either San Mateo or Santa Clara County to the San Francisco Chronicle by the Zodiac Killer for the first time. The letter (minus the Asian symbols) was published in the San Francisco Chronicle newspaper on January 31st 1974, but the envelope was not released into the public domain prior to the arrival of the April 24th 1978 letter. Up to 1978, every single Zodiac communication that carried the *Please Rush to Editor" message on the reverse side of the envelope was either written in diagonal fashion or not contained on one line - except for one - which was written using a single line and was parallel to the upper and lower edges of the envelope. That was the Paul Stine envelope (containing the shirt piece) mailed on October 13th 1969, which was also withheld from the public domain prior to April 24th 1978.

​The only available envelope addressed to the San Francisco Chronicle newspaper that the 1978 letter author had available for them to mimic, was the November 8th 1969 envelope released in a newspaper article on November 16th 1970. This newspaper article clearly shows the front and back of the envelope, with "Please Rush to Editor" written in level fashion on the front of the envelope and in diagonal fashion on the rear of the envelope. The author of the 1978 envelope seemingly did an excellent job mimicking the handwriting on the front side of the November 8th 1969 envelope, yet inexplicably failed to write "Please Rush to Editor" in level fashion on the front of their 1978 envelope. Additionally, the author of the 1978 envelope failed to write "Please Rush to Editor" in diagonal fashion on the rear of the envelope, again failing to mimic the November 8th 1969 envelope - instead opting to mimic the Paul Stine letter which was never released into the public domain. In fact, the 1978 envelope was the only communication connected to the Zodiac Killer with the writing "Please Rush to Editor" in diagonal fashion on the front of an envelope. This copycat certainly wasn't very observant - apparently losing his train of thought from one side of the envelope to the other. Also, according to investigators, the author of the 1978 letter managed to mail the communication from either San Mateo or Santa Clara County, just like the Exorcist letter, four years earlier. Strange how he apparently never forgot that.

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.
