To indent writing is to begin text with a blank space between it and the margin

Take a look at the the four consecutive known letters from April 24th 1978, May 2nd 1978, May 6th 1986 and October 28th 1987, shown below. Now imagine these are from different authors hoaxing Zodiac letters. All four managed to use "indented writing" on the opening introduction of "This is the Zodiac speaking", which was never used prior to 1978 in any of the four published introductions in the San Francisco Chronicle (or in any Zodiac communications). This means that despite having the "This is the Zodiac speaking" introduction available for them to mimic, all four (or multiple) authors failed to keep the introduction in line with the text beneath it (signifying a consistent change in pattern). Subsequent to the introduction, all four authors also began with the personal pronouns of "I" and "You". In three of these the text begins with "I". All of these three examples fail to use correct punctuation between "speaking" and "I". Ideally, these two words should be separated with a comma or full stop (period), but in every instance the author fails to do so, just like the authenticated Melvin Belli letter from December 20th 1969, an image of which was not available to the author of the 1978 letter (if they were a hoaxer). This should prove beyond any reasonable doubt we are dealing with one author who penned the December 20th 1969, April 24th 1978, May 6th 1986 and October 28th 1987 letters. It should also prove it was the Zodiac Killer who wrote at least four of the letters, one of which we know has a full DNA profile. If the 1978 envelope has DNA beneath the stamp and/or envelope seal, why not the others? The 1978, 1986 and 1987 letters are almost certainly genuine Zodiac communications, so why were law enforcement attempting to secure Zodiac DNA from two of the July 31st 1969 envelopes nearly four years ago, when they already have it? Sadly, this is another avenue that will be ignored.

Thanks to Druzer for his great work on this topic of indented writing.    

In the San Francisco Examiner on August 3rd 1978, four experts, Keith Woodward (head of Los Angeles documents department), John Shimoda (Postal Service crime laboratory), Robert Prouty (Chief documents section/Bureau of Criminal Identification and Investigation) and Terry Pasco (also Criminal Identification and Investigation), all deemed the 1978 letter a fake. Keith Woodward described the 1978 letter "a carefully drawn copy of the true Zodiac printing". He concluded it "was a poor attempt by an unknown writer". John Shimoda declared it "an attempt to duplicate Zodiac letters and is not authentic". Robert Prouty and Terry Pasco said basically the same thing, while Robert Graysmith disingenuously turned on this letter when he realized the DNA extracted from it didn't match the profile of Arthur Leigh Allen, claiming a light table may have been employed to hoax the letter. He then boldly trumpeted the above arguments of handwriting analysis - a subjective analysis - that has forever divided document examiners in the case of JonBenet Ramsey and the three-page ransom note supposedly authored by a "foreign faction".

Handwriting analysis cannot be used to exclusively and definitively argue for the authenticity, or otherwise, of a Zodiac communication. However, it can be used as a supporting argument where other evidence exists. This still hasn't stopped vociferous sections of the Zodiac community buying into the notion of an authenticated list of Zodiac communications based solely upon the narrative they have been sold from day one. 

Let us look at the words of John Shimoda, who stated that the 1978 letter was "an attempt to duplicate Zodiac letters and is not authentic". The author of the 1978 letter was that good at duplicating Zodiac letters, they failed to duplicate the opening introduction of "This is the Zodiac speaking", which was always self-contained on a separate line in every confirmed Zodiac communication mailed to the San Francisco Chronicle, San Francisco Examiner and Los Angeles Times prior to 1978. The hoaxer had four examples of this to copy from the San Francisco Chronicle newspaper, when it released images of the ​October 13th 1969, November 8th 1969, April 20th 1970 and March 13th 1971 letters to the public (see images below). The hoaxer failed to copy any of these. Instead, they wrote "This is the Zodiac speaking I" (mimicking the unreleased image of the Melvin Belli letter and its punctuation error). The author of the 1978 letter had the January 29th 1974 Exorcist letter available to them - widely published in the San Francisco Chronicle on January 31st 1974 - yet they failed to misspell "truly" to "truley", clearly evident in the Exorcist letter. The author of the 1978 letter failed to add a customary running total, which would have been the easy option to choose for somebody wanting to convince us they were Zodiac. Instead they placed the word "guess". The author of the 1978 letter failed to keep the "This is the Zodiac speaking" introduction in line with the text beneath it (thanks Druzer). In the 1978 letter they used "indented writing" (to indent is to begin text with a blank space between it and the margin). This absence of indented writing during the introduction phase was present in every published letter up to 1978 (see below). So, you can see that the claim of the 1978 letter author attempting to "duplicate Zodiac letters" from the newspapers, carries no merit whatsoever. This individual wasn't attempting to copy anybody. 

If there is one letter that "suspect chasers" have a vested interest in dismissing out of hand, it's the 1978 letter (because a DNA sample has been obtained from it). If their suspect's DNA is available for comparison to a genuine Zodiac letter tomorrow, then it would only be a matter of days or weeks before their suspect is possibly confined to the compost heap of history, along with many other poor suspects in this case. They cannot take that chance, so play the odds and reject the letter beforehand. It is in the interest of "suspect chasers" to never accept the bloody taxicab fingerprint as originating from Zodiac (if their suspect's fingerprints exist on file), to never accept that Zodiac licked the stamps and envelopes, to never accept the 1978 letter as genuine, and for a minority, that DNA is never found in the Zodiac case. The longer they can promote their suspect, the better.

The Zodiac community have been eager to constantly enquire about the round of DNA testing reported in 2018, but show little interest in submitting the 1978 letter for familial DNA analysis. The reason for this apathy, is that many have looked at the 1978 communication and concluded it wasn't authored by the Zodiac Killer, primarily because they didn't like the handwriting or the tone of the letter. You cannot argue with research like this. For those who believe the 1978 letter is genuine, the search for Zodiac DNA is over. 

This is a continuation from the article The Day the Zodiac Killer Rang Oklahoma. The original article will be replicated here under Part One, immediately followed by some fresh information under Part Two (with the help of Zodiac Killer Net forum).

Part One: ​An imposter by the name of Eric Weill called into the Jim Dunbar KGO-TV station on the morning of October 22nd 1969 and attempted to pass himself off to the host and Melvin Belli as the infamous Zodiac Killer. During the phone call Eric Weill pleaded with Melvin Belli, stating "I want help".  On October 23rd 1969, the Desert Sun newspaper claimed that Melvin Belli told the caller “All of San Francisco wants to help you. The hand is out, you can feel the hands out.” The Zodiac Killer clearly latched onto this plea for help, when in mocking fashion he wrote to the residence of Melvin Belli on December 20th 1969 and stated "please help me" on three occasions, in accompaniment to the phrase "I cannot reach out for help". However, this wasn't the first time the Zodiac Killer would mock the spectacle of the Jim Dunbar Show, when on December 7th 1969 he mailed a letter from Fairfield to the San Francisco Chronicle stating "I just need help. I will kill again so expect it any time soon the will be a cop". Thirteen days later, the Melvin Belli letter would replicate this plea for help, despite the fact the December 7th 1969 correspondence was never released to the newspapers. But here's the kicker.

After the Zodiac Killer communication, postmarked December 7th 1969, a phone call was received later that night by the host of commercial radio station KTOK in Oklahoma City claiming to be from the Zodiac Killer. KTOK news director Larry Lamotte told the San Francisco Chronicle that a man rang the station and declared that he had to leave California because "it got too hot for me", remarking that the man did an awfully good impression of the man who rang the Jim Dunbar Show on October 22nd 1969. This is the crucial part. On the same day of December 7th 1969, we have a man mailing a letter to the San Francisco Chronicle mocking the call to the Jim Dunbar Show by stating "I just need help", followed a few hours later by a call to an Oklahoma radio station by a man doing an awfully good impression of the man who rang the Jim Dunbar Show on October 22nd 1969. This impressionist caller could possibly be the Zodiac Killer mocking the Jim Dunbar Show, just as he had done in the letter earlier that day - and would do thirteen days later when he thrice pleaded "please help me". There is no way of finding out the full transcript of the phone call to the Oklahoma radio station, but it wouldn't be too far-fetched to believe he mockingly asked for help on this occasion too.   

The caller to the Oklahoma radio station, doing an impression of the Jim Dunbar Show caller, claimed he left California because "it got too hot for me". A few hours before the October 22nd 1969 Oakland Police Department phone call requesting that either Melvin Belli or Francis Lee Bailey, high profile lawyers at the time, appear on a chat show hosted by Jim Dunbar later that day, somebody rang the Palo Alto Times newspaper claiming to be the Zodiac Killer and stated that he had left San Francisco because "because I'm too hot there". Two similar pieces of phraseology connected by two phone calls and the Jim Dunbar Show.

​In addition, we have the December 7th 1969 letter stating "I will kill again so expect it any time soon the will be a cop", followed by the December 16th 1969 Fairfield letter listing 38 "cops" as potential victims, and a December 19th 1969 payphone call to Sergeant Robert Rengsdorff of the San Jose Highway Patrol threatening "I am going to kill five of you officers and a family of five between now and Monday". Three threats to kill cops within twelve days of December. Then came the mocking Melvin Belli letter just one day later. Neither of the Fairfield letters were released to the newspapers, making the December 19th 1969 payphone caller just another lucky chap if it wasn't the Zodiac Killer. It is fairly evident that the Zodiac Killer was responsible for many more phone calls than the two he has been accredited with, including a phone call to the Santa Rosa Police Department on October 15th 1969. 

The apparent familiarity with the KTOK radio station, by choosing to call one of its hosts over 1,000 miles from the Bay Area, could suggest an affinity to their style of broadcasting. During the 1960s KTOK radio station featured news, sport and adult music, with the 1960 Broadcasting Yearbook describing its content as "toe tapping music (no rock and roll) and all the announcers are adults". That music included such artists as Tony Bennett, The Mills Brothers and Al Martino. This may give an insight into the maturity and age of the Zodiac Killer when the phone call was made on December 7th 1969, in a year when all three sets of eyewitnesses at Presidio Heights described the Zodiac Killer as 40 years or above. Was the Zodiac Killer an avid listener to this radio station, or did he once have roots in Oklahoma?   

Part Two: Then came the ridiculous statements in the Lodi News-Sentinel by a detective sergeant and KTOK news director, Larry Lamotte. The detective sergeant told the Sentinel that "Major Miller told us it was a hoax. I don't know if we even looked into the case". Apparently the police ended their investigation inside of one day - and according to Larry Lamotte they didn't even come to collect recordings of the man's voice when offered the tapes. Larry Lamotte remarked "I don't see how it can be anything but a hoax. The caller was too familiar with Oklahoma City. He knew the name of our shopping centers and mentioned our high rate of traffic fatalities and even the governor's 'Live for the 70s program". Well, maybe he had visited Oklahoma recently, and/or had possibly lived there at some point Larry. Maybe he read newspapers and magazines.   

When the caller was asked if he was the Zodiac Killer, he stated "I could be", and added that "I don't need to kill. There are too many people killed on the highways and that's legal". The conversation continued with the caller remarking "You're going to try and trace it" - and when met with the affirmative - replied "then I better hang up". The caller added one final thing, threatening more killings by stating "There are plenty of parking lots" - mentioning one large Oklahoma shopping center by name. This call to Oklahoma City on December 7th 1969 came forty-seven days after the Jim Dunbar Show, yet it mimicked the October 22nd 1969 call to KGO-TV station the very same day a Zodiac letter was postmarked to the San Francisco Chronicle, also mimicking the Jim Dunbar Show hoaxer by stating "I just need help". Again, predating the Melvin Belli letter on December 20th 1969 that thrice pleaded "please help me". The caller to the Oklahoma radio station stated he had to leave California because "it got too hot for me", just like the caller to the Palo Alto newspaper just hours before the Oakland Police Department call in the early morning hours of October 22nd 1969. On that occasion the caller stated that he left San Francisco "because I'm too hot there". So, the notion the Oklahoma City caller was an isolated hoaxer that was currently resident in Oklahoma doesn't stack up, especially when you consider the December 7th 1969 letter was postmarked Fairfield, California. This Oklahoma City recording could reveal the true voice of the Zodiac Killer. At the very least, it should have been played to Bryan Hartnell, Nancy Slover and David Slaight, who had all heard the Zodiac Killer's voice a matter of months earlier.       

Additional Information: On October 19th 1969, the San Francisco Examiner ran an article entitled "Message to the Zodiac Killer". It read: "Five people are dead. Let there be no more killings. Police say you are intelligent. If you are, then listen to reason. You are being hunted everywhere in the state, and nation. You are alone in this world. You can share your secrets with no one. No friend can help you. You are as much a victim of your crimes as those whose lives you snuffed out. You cannot walk the streets a free man. There is no safety for you, anywhere. And you will be caught, there is no doubt. You face life as a hunted, tormented animal - unless you help yourself. We ask that you give yourself up to the Examiner. We offer you no protection, and no sympathy. But we do offer you fair treatment, the assurance of medical help and the full benefits of your legal rights. And we offer to tell your story. Why have you killed? How has life wronged you? Call the City Editor of the Examiner any time, day or night. The telephone number is (415) 781 24 24. Call collect. Your call will not be traced".

This message may have inspired the Zodiac Killer to ring the Oakland Police Department on October 22nd 1969 requesting that either Melvin Belli or Francis Lee Bailey, two high profile lawyers at the time, appear on a chat show hosted by Jim Dunbar later that day. The San Francisco Examiner article was published on October 19th 1969 with the assurance of "legal rights" if the Zodiac Killer phoned in - and requested the murderer to "give yourself up". It was reported in a magazine article in August 1971 that after the caller to Oakland Police made contact, the main thrust of the conversation was that the Zodiac Killer wanted to give himself up, but only if he could be represented by a famous lawyer. Approximately six weeks after the Oakland call, a letter mailed on December 7th 1969 to the San Francisco Chronicle (now validated as Zodiac correspondence), mocked the dialogue in the Jim Dunbar Show by opening his communication with "I just need help", but after threatening to kill a cop he stated "I will turn myself in". This was the only time the Zodiac Killer offered to turn himself in, other than the caller to the Oakland Police Department. To the best of my knowledge no newspaper articles immediately subsequent to the Jim Dunbar Show mentioned the Oakland caller offering to turn himself in - and neither did the Jim Dunbar Show hoaxer. This last section will be deleted if fresh information proves otherwise.  

On April 24th 1978, a letter arrived at the San Francisco Chronicle declaring "I am back with you", authenticated by documents examiner, Sherwood Morrill. Then came the arrival of San Francisco Chronicle columnist, Armistead Maupin, who joined the San Francisco Associated Press in 1971, and went on to launch nine novels that included the popular Tales of the City series. He caused a stink when he revealed that Inspector David Toschi had forged fan mail in regards to his character in the Tales of the City series, which resulted in Inspector David Toschi being demoted to pawn shop detail despite no solid evidence he crafted the 1978 letter.

​Then came further handwriting experts claiming that the 1978 letter looked traced and too similar to previous correspondence. In the San Francisco Examiner on August 3rd 1978, four experts, Keith Woodward (head of Los Angeles documents department), John Shimoda (Postal Service crime laboratory), Robert Prouty (Chief documents section/Bureau of Criminal Identification and Investigation) and Terry Pasco (also Criminal Identification and Investigation), all deemed the 1978 letter a fake. Keith Woodward described the 1978 letter "a carefully drawn copy of the true Zodiac printing". He concluded it "was a poor attempt by an unknown writer". John Shimoda declared it "an attempt to duplicate Zodiac letters and is not authentic". Robert Prouty and Terry Pasco said basically the same thing. 

The experts concluded that the 1978 was effectively a "copy", attempting to duplicate authentic Zodiac letters. So how did the author of the 1978 letter duplicate the Melvin Belli letter introduction, when an image of this communication had never been published in the newspapers. If the author of the 1978 letter was attempting to imitate previous Zodiac communications so precisely, then why didn't he duplicate the introduction of "This is the Zodiac speaking" from at least four letters published in the newspapers?. He couldn't have been imitating the Zodiac Killer very well. Here is an excerpt from a previous article. ​

​From August 4th 1969 to March 13th 1971 the Zodiac Killer mailed 12 authenticated letters (inc. Fairfield letters} that carried the introduction of "This is the Zodiac speaking" on the first line of the message. Of these 12 letters, only the Melvin Belli letter on December 20th 1969 failed to keep the "This is the Zodiac speaking" introduction exclusively on the main first line (ignoring the "Dear" intro). It was written "This is the Zodiac speaking I". The San Francisco Chronicle published at least four of these introductions, which included the October 13th 1969, November 8th 1969, April 20th 1970 and March 13th 1971 letters (shown here).

The author of the April 24th 1978 "I am back with you" letter (if a hoaxer) had every opportunity to just mimic any one of these published introductions, yet he chose to mimic the Melvin Belli letter on December 20th 1969, which broke with tradition. The Melvin Belli message began with "This is the Zodiac speaking I", but was grammatically incorrect in failing to place a comma or full-stop between "speaking" and "I". Therefore, the author of the 1978 letter (if a hoaxer) managed to imitate the message on the opening line of the Melvin Belli letter (including the punctuation error) despite the fact an image of the Melvin Belli letter was not published in any newspapers (to my knowledge). One would have expected a Zodiac copycat to mimic any one of the four introductions available in the San Francisco Chronicle  - but they didn't. The 1978 author mimicked the only one not publicly available in the Chronicle. Both letters also began with the author addressing the receiver by way of "Dear Melvin" and "Dear Editor". From August 4th 1969 to March 13th 1971, this "addressing of the receiver" within the letter was only performed twice (8/4/69 and 12/20/69). These observations may suggest the Zodiac Killer authored the 1978 letter after all. When you consider the same introduction present in the Melvin Belli and 1978 letter, was it just coincidence that the Melvin Belli letter stated "I can not remain in control for much longer", to which the 1978 letter replied with "I am now in control of all things"? 

According to Mike Rodelli, Alan Keel, Criminalist at the San Francisco Police Department "revealed that there were two letters in possession of the department that had abundant saliva and DNA-containing oral epithelial cells on them, and that the DNA extracted from these two letters matched between them". The San Francisco Police Department DNA chart concurred that a DNA sample was obtained from the 1978 letter. Zodiac researcher, Michael Butterfield, curator of the Zodiac Killer Facts website, wrote in an article entitled The Magic Bullet, that In the late 1990s San Francisco police obtained DNA from a suspected Zodiac letter, and the DNA did not match Allen’s DNA. That communication was the 1978 letter, described in comments in the DNA chart as "DNA Sample Obtained". The evidence above, strongly points to the 1978 letter being a genuine Zodiac letter, unless of course, the hoaxer just happened to ignore the widely publicized letters in the newspapers carrying the usual introduction, and instead opted to mimic the introduction and error in punctuation in the Melvin Belli letter, which they could never have seen an image of.  

In late 2017 there was optimism regarding a new round of testing of the Zodiac letters. In early 2018, the Sacramento Bee reported that "Vallejo police Detective Terry Poyser, who has worked the Zodiac case for four years, said his agency has submitted two envelopes (in late 2017) that contained letters from the Zodiac Killer for a type of advanced DNA analysis that previously had not been available in the case. Poyser declined to identify the lab, but said it would attempt to obtain a full DNA profile from saliva on the envelope flap and stamps. He said he expected to have results back from the lab as soon as in the next few weeks, and almost certainly by summer". But according to the above sources and the "DNA Sample Obtained" comment by the San Francisco Police Department laboratory, we already have a DNA sample from the 1978 letter. Therefore, with little doubt, we have DNA from the Zodiac Killer - and have done for many years. This DNA from the 1978 letter should now be run through the genealogy database to generate fresh information in this long-standing case. If Alan Keel is correct, then we definitively have a full DNA profile of the Zodiac Killer from the 1978 letter, that he claimed matched one of the 1974 letters (which could very well be the Exorcist letter, as this was the only 1974 letter processed for DNA according to the chart). This sounds plausible, because recent information has shown that the Exorcist letter is probably genuine Zodiac correspondence based on comparisons between envelopes. All of this should exonerate David Toschi of having any involvement in forging Zodiac letters, and exclude Arthur Leigh Allen once and for all. But if the Exorcist letter and 1978 letter matched in DNA - and the 1978 letter was considered a forgery by investigators - why hasn't the Exorcist letter been more heavily questioned as authentic? Irrespective of any matches noted by Alan Keel, if the 1978 letter provided a DNA sample, then we may be able to identify the Zodiac Killer if the arguments made using the Melvin Belli letter stack up.

ADDITIONAL READING: A PATTERN OF WRITING  

Many people believe that the Zodiac Killer's "terroristic" exploits didn't begin with Lake Herman Road on December 20th 1968 and the subsequent letter writing campaign - and have searched in the Editor's columns of newspapers for any hints of Zodiac type language. The following does not claim this is a Zodiac communication, but it is worthy of a mention because it involves a threatening letter to Mr. Melvin Belli prior to the inception of the Zodiac Killer.

A typewritten letter was postmarked Starkville, Mississippi on March 24th 1964, addressed to Mr. Melvin Belli, Attorney at Law, San Francisco, California, with a return address of R. A. Wagner, 1302 E. Capitol Street, Jackson, Mississippi. Investigators could find no such number on E. Capitol Street and no R. A. Wagner by searching the Polk Directory in Mississippi. The letter read:

"Old Dago Belli says of Dallas, 'This city stinks', We have news for you jelly belli -- that's your upper lip you smell. Furthermore, if you're not careful some-body's going to put a slug of hot lead between those beady eyes of yours". It was signed "The Commitee" and followed by "Remember, San Francisco is no sanctuary."         

This letter was in response to the conviction and death sentence imposed on Jack Ruby on March 14th 1964 for the killing of Lee Harvey Oswald, and Melvin Belli's response to the verdict. Melvin Belli, who defended Jack Ruby, was quoted in a newspaper article: "ANOTHER MAN ON THE STREET, L. D. ENNES, DECLARED: "I THINK IF IT. HAD GONE ANY OTHER WAY, IT WOULD HAVE BEEN A DISGRACE TO OUR LAWS." THERE WERE THOSE, HOWEVER, WHO SIDED WITH BELLI. BESIDE HIMSELF WITH RAGE AT THE VERDICT, THE NORMALLY SUAGE SAN FRANCISCO LAWYER ROARED IN COURT WITH RAGE AT THE VERDICT, THE NORMALLY SUAVE SAN FRANCISCO LAWYER ROARED IN COURT: "THIS IS A VICTORY FOR BIGOTRY. DON'T WORRY JACK, WE'LL APPEAL THIS AND TAKE IT OUT OF TEXAS." THE 55-YEAR-OLD BELLI WAS EQUALLY VEHEMENT TODAY IN ASSERTING, "THIS CITY STINKS." 

Mississippi was a hotbed of racial tension in the civil rights movement era, with the murders of Chaney, Goodman, and Schwerner, also known as the Freedom Summer murders, the Mississippi civil rights workers' murders or the Mississippi Burning murders, which occurred in the latter half of 1964. The reason I bring this up, is the name adopted by the sender from Mississippi. Why would the sender choose this name? Richard Wagner was a German composer,  theater director, polemicist, and conductor who is chiefly known for his operas. "The self-taught 19th-century German composer was born into a performing family – several of his sisters became opera singers and actresses. A vehement anti-Semite, Wagner is one of the most controversial figures in the history of classical music. The Ku Klux Klan-glorifying 1915 silent film, The Birth of a Nation, featured music from one of Wagner’s operas, Ride of the Valkyries". Post Magazine.. Adolf Wagner was a German soldier and high-ranking Nazi Party official born in Algrange, Alsace-Lorraine, and appointed by Adolf Hitler. So, did the roots of racism play any part in the fictitious name chosen by the sender from Mississippi.  

On August 26th 1976, a personal advertisement mentioning "The Imperial Wizard" and beginning with "ZODIAC" was placed in the San Francisco Chronicle to run for one week. This advertisement carried the initials R. A., just like the threatening letter from Mississippi addressed to Mr. Melvin Belli.

From August 4th 1969 to March 13th 1971 the Zodiac Killer mailed 12 authenticated letters (inc. Fairfield letters} that carried the introduction of "This is the Zodiac speaking" on the first line of the message. Of these 12 letters, only the Melvin Belli letter on December 20th 1969 failed to keep the "This is the Zodiac speaking" introduction exclusively on the main first line (ignoring the "Dear" intro). It was written "This is the Zodiac speaking I". The San Francisco Chronicle published at least four of these introductions, which included the October 13th 1969, November 8th 1969, April 20th 1970 and March 13th 1971 letters (shown below). The author of the April 24th 1978 "I am back with you" letter (if a hoaxer) had every opportunity to just mimic any one of these published introductions, yet he chose to mimic the Melvin Belli letter on December 20th 1969, which broke with tradition. The Melvin Belli message began with "This is the Zodiac speaking I", but was grammatically incorrect in failing to place a comma or full-stop between "speaking" and "I". Therefore, the author of the 1978 letter (if a hoaxer) managed to imitate the message on the opening line of the Melvin Belli letter (including the punctuation error) despite the fact an image of the Melvin Belli letter was not published in any newspapers (to my knowledge). One would have expected a Zodiac copycat to mimic any one of the four introductions available in the San Francisco Chronicle (images below) - but they didn't. The 1978 author mimicked the only one not publicly available in the Chronicle. Both letters also began with the author addressing the receiver by way of "Dear Melvin" and "Dear Editor". From August 4th 1969 to March 13th 1971, this "addressing of the receiver" within the letter was only performed twice (8/4/69 and 12/20/69). These observations may suggest the Zodiac Killer authored the 1978 letter after all. Up to and including 1978, the Melvin Belli and "I am back with you" letters were the only two letters that opened with the message "This is the Zodiac speaking I". Therefore, was it just coincidence that the Melvin Belli letter stated "I can not remain in control for much longer", to which the 1978 letter replied with "I am now in control of all things"?

This, along with the observations shown in a previous article, should help to authenticate a letter long believed to be a hoax by many in the Zodiac community. This could very well rule out David Toschi as the author of the 1978 letter and finally clear his name altogether. The San Francisco Police Department DNA report states that a "DNA sample was obtained" from the 1978 letter. Therefore, if the 1978 letter is genuine, we already have the Zodiac Killer's DNA. If anybody has information showing that the Melvin Belli letter was published in the newspapers prior to April 24th 1978, please let me know and this article will be amended or deleted.   

I would like to thank Zodiac researcher Druzer, whose initial insights into the structure of the Zodiac letters have made all this possible. Including the article "A Pattern of Writing".  

An imposter by the name of Eric Weill called into the Jim Dunbar KGO-TV station on the morning of October 22nd 1969 and attempted to pass himself off to the host and Melvin Belli as the infamous Zodiac Killer. During the phone call Eric Weill pleaded with Melvin Belli, stating "I want help".  On October 23rd 1969, the Desert Sun newspaper claimed that Melvin Belli told the caller “All of San Francisco wants to help you.

However, this wasn't the first time the Zodiac Killer would mock the spectacle of the Jim Dunbar Show, when on December 7th 1969 he mailed a letter from Fairfield to the San Francisco Chronicle stating "I just need help. I will kill again so expect it any time soon the will be a cop". Thirteen days later, the Melvin Belli letter would replicate this plea for help, despite the fact the December 7th 1969 correspondence was never released to the newspapers. But here's the kicker.

After the Zodiac Killer communication, postmarked December 7th 1969, a phone call was received later that night by the host of commercial radio station KTOK in Oklahoma City claiming to be from the Zodiac Killer. KTOK news director Larry Lamotte told the San Francisco Chronicle that a man rang the station and declared that he had to leave California because "it got too hot for me", remarking that the man did an awfully good impression of the man who rang the Jim Dunbar Show on October 22nd 1969. This is the crucial part. On the same day of December 7th 1969, we have a man mailing a letter to the San Francisco Chronicle mocking the call to the Jim Dunbar Show by stating "I just need help", followed a few hours later by a call to an Oklahoma radio station by a man doing an awfully good impression of the man who rang the Jim Dunbar Show on October 22nd 1969. This impressionist caller could possibly be the Zodiac Killer mocking the Jim Dunbar Show, just as he had done in the letter earlier that day - and would do thirteen days later when he thrice pleaded "please help me". There is no way of finding out the full transcript of the phone call to the Oklahoma radio station, but it wouldn't be too far-fetched to believe he mockingly asked for help on this occasion too.   

The caller to the Oklahoma radio station, doing an impression of the Jim Dunbar Show caller, claimed he left California because "it got too hot for me". A few hours before the October 22nd 1969 Oakland Police Department phone call requesting that either Melvin Belli or Francis Lee Bailey, high profile lawyers at the time, appear on a chat show hosted by Jim Dunbar later that day, somebody rang the Palo Alto Times newspaper claiming to be the Zodiac Killer and stated that he had left San Francisco because "because I'm too hot there". Two similar pieces of phraseology connected by two phone calls and the Jim Dunbar Show.

​In addition, we have the December 7th 1969 letter stating "I will kill again so expect it any time soon the will be a cop", followed by the December 16th 1969 Fairfield letter listing 38 "cops" as potential victims, and a December 19th 1969 payphone call to Sergeant Robert Rengsdorff of the San Jose Highway Patrol threatening "I am going to kill five of you officers and a family of five between now and Monday". Three threats to kill cops within twelve days of December. Then came the mocking Melvin Belli letter just one day later. Neither of the Fairfield letters were released to the newspapers, making the December 19th 1969 payphone caller just another lucky chap if it wasn't the Zodiac Killer. It is fairly evident that the Zodiac Killer was responsible for many more phone calls than the two he has been accredited with, including a phone call to the Santa Rosa Police Department on October 15th 1969. 

The Zodiac Killer may have attempted to ring the Jim Dunbar Show before the murder of Paul Stine on October 11th 1969. On October 22nd 1969, Eric Weill (Sam) rang into the morning KGO-TV Jim Dunbar Show - but when Jim Dunbar and Melvin Belli interviewed this man it was on the understanding he may have been the infamous Zodiac Killer, with the host asking him "Did you try to call us one other time, about two or three weeks ago". This suggests that Jim Dunbar was aware of a previous attempt by the Zodiac Killer to contact the show prior to the murder of Paul Stine in Presidio Heights on October 11th 1969. The Zodiac Killer may have attempted to contact the Jim Dunbar Show for a second time, when he rang the Oakland Police Department on October 22nd 1969, but again his debut on the show was thwarted by imposter Eric Weill. With this in mind, did he then choose to redirect his attention to a different radio station in Oklahoma on December 7th 1969? But why would he choose KTOK radio station in Oklahoma? There has to be a reason.  

The apparent familiarity with the KTOK radio station, by choosing to call one of its hosts over 1,000 miles from the Bay Area, could suggest an affinity to their style of broadcasting. During the 1960s KTOK radio station featured news, sport and adult music, with the 1960 Broadcasting Yearbook describing its content as "toe tapping music (no rock and roll) and all the announcers are adults". That music included such artists as Tony Bennett, The Mills Brothers and Al Martino. This may give an insight into the maturity and age of the Zodiac Killer when the phone call was made on December 7th 1969, in a year when all three sets of eyewitnesses at Presidio Heights described the Zodiac Killer as 40 years or above. Was the Zodiac Killer an avid listener to this radio station, or did he once have roots in Oklahoma?   

So, could the 38 character code hold some further reference to the Jim Dunbar Show, or the upcoming appearance on the KTOK radio station? If the Z38 is somehow related to the Z340 (through its opening 4 characters and 5 ending characters), does it carry a similar message? The first communication after the Jim Dunbar Show on October 22nd 1969 was the 'Dripping Pen' card and 340 cipher mailed on November 8th 1969, stating "that wasn't me on the TV show". With the December 7th 1969 letter and KTOK radio call coming on the same day, could it have any bearing on the message contained within the code? "That was me on the Oklahoma radio station" would have certainly been the ideal contemporary message to encode.  

On September 27th 1969, Bryan Hartnell and Cecelia Shepard were brutally stabbed at Lake Berryessa in Napa County, with the Zodiac Killer leaving his signature at the crime scene by writing on the Volkswagen Karmann Ghia near the crime scene. Two weeks later, on October 11th 1969, Paul Stine was shot in his taxicab in the wealthy district of Presidio Heights, with the Zodiac Killer this time removing something personal from the victim, by tearing a piece of Paul Stine's blooded shirt and mailing a portion of it to the San Francisco Chronicle on October 13th 1969.

​A crime was six months in the making, incorporating features from both of these attacks, when Robert Michael Salem was knifed to death in his 745 Stevenson Street, San Francisco apartment on April 15th 1970. The killer appeared to mimic the Zodiac Killer's two previous attacks by writing a message at the crime scene, as well as removing something from the victim. However, the attack on Robert Salem was an escalation on the other attacks in regards to the sadistic nature of the crime. The killer had written the message on the apartment wall of Robert Salem in blood and taken the left ear of the victim away from the crime scene (never to be retrieved). By all accounts, the murderer had first attempted to decapitate Robert Salem. The third important facet of this crime, was that it appeared to mimic the meaning behind the Zodiac Killer's last communication on December 20th 1969, when the Melvin Belli letter arrived at 1228 Montgomery Street in San Francisco. The letter mailed to the prominent attorney could have foreshadowed the Robert Salem murder, not only because the killer of Robert Salem was seemingly "losing all control", but because the wording in the Melvin Belli letter appeared to mimic the writing in red lipstick on the apartment wall of Frances Brown, murdered by William Heirens in Chicago in 1945. 

William Heirens was also found guilty for the murder of 6-year-old Suzanne Degnan in Chicago in 1946. Her body had been dismembered just like Robert Salem, albeit far more brutally. Her head was eventually discovered in a nearby sewer, her right leg in a catch basin and her torso in a storm drain. The killer of Robert Salem had attempted to decapitate him just like Suzanne Degnan, before apparently giving up and removing his left ear. Therefore, the 745 Stevenson Street murder not only had writing at the crime scene and something from the victim removed, but the red writing and attempted decapitation mirrored two of the crimes committed by William Heirens, which may have inspired the wording in the Melvin Belli letter. William Heirens was also responsible for the murder of Josephine Ross in Chicago in 1945, with all three victims subjected to numerous knife wounds, just like Robert Salem. 

The San Francisco murder of Robert Salem seemed like extreme overkill for robbery or revenge, due in large part to the sadistic nature of the crime and the writing in blood on the apartment wall. The killer then took the time to take a shower before leaving. The killer drew an ancient Egyptian ankh symbol on the wall of the apartment, accompanied by the wording "Satan Saves" and the pseudonym "Zodiac". The ankh appears frequently in Egyptian tomb paintings and other art, often at the fingertips of a god or goddess in images that represent the deities of the afterlife conferring the gift of life on the dead person's mummy. If the murderer of Robert Salem was attempting to sidetrack the police investigation and pin this crime on the Zodiac Killer, why didn't he just use the crosshairs symbol of the Bay Area murderer, write on the wall in black marker pen and refrain from decapitating Robert Salem, which would have helped his attempt to frame the Zodiac Killer as being the responsible. This approach would surely have been far easier. Additonally, if the murderer was not the Zodiac Killer, was the killer of Robert Salem just extremely fortuitous in creating a crime scene at 745 Stevenson Street that just happened to mimic two of William Heirens crimes, which may have been mimicked in the Melvin Belli letter - and the last communication mailed by the Zodiac Killer with an item removed from the victim, that of Paul Stine? Or had the killer of Robert Salem worked out the meaning behind the Melvin Belli letter and made the connection to the William Heirens murders in order to mimic them four months later? Could you have imagined the repercussions had it been reported that an ear had been mailed on April 20th 1970 to the San Francisco Chronicle. 

The Zodiac Killer mailed the 148 character cipher and letter on or around May 2nd 1971, in which he refrained from taking the easy option of using his Zodiac crosshairs, when he signed his letter using a sun cross from prehistoric cultures. But did he employ the same technique on April 15th 1970, designed to confuse law enforcement until his April 20th 1970 letter arrived, A letter that didn't carry the wording "Satan Saves", but did carry the numerical figure of Jesus, with the added notation of "PS I hope you have fun trying to fiygure out who I killed". The crime scene at 745 Stevenson Street appeared to be the work of a brutal and sadistic killer more in line with a murderer "losing all control" - and in direct contrast with the Zodiac Killer who never went further than necessary in his requirement to murder. Unless of course, the Zodiac Killer took the wording in the Melvin Belli letter seriously and enacted the 1945 murder of Frances Brown in Chicago to the new setting of San Francisco. He certainly liked his history.   

Just like the attempted poisoning of Daniel Williams on November 2nd 1969, the murder of Robert Michael Salem just prior to the Zodiac Killer's letter on April 20th 1970, is another case of possible Zodiac activity too readily dismissed. There are many potential clues in the April 20th 1970 letter to the Robert Salem murder, but here we shall focus on just one aspect of the case.

The Zodiac Killer likely switched to murder by knife at Lake Berryessa because of the contast he noted in newspaper coverage between his crimes and the double murder of Kathy Snoozy and Deborah Furlong in San Jose on August 3rd 1969. The Zodiac Killer had murdered three people, attempted to murder a fourth, and mailed four letters and three cryptograms to high profile Bay Area newspapers. Imagine his "consternation", when discovering that the highest circulation newspapers in the Bay Area ignored his demands and relegated the cryptic murderer of three into relative anonymity on their inner pages.

The San Francisco Chronicle published his cryptogram on page four, while the San Francisco Examiner had placed their portion of the cipher on a lowly page nine. This was shortly followed by a comprehensive front page article in the San Francisco Chronicle on August 6th 1969, covering the brutal stabbings of Snoozy & Furlong in San Jose. The Zodiac Killer, likely scouring the newspapers for information about himself and the ongoing effort to crack his 408 cryptogram, must have read this article and been understandably horrified. He now knew what he had to do to secure the front page coverage he felt he richly deserved - kill his next victims with a knife. This was probably the trigger for his emphasis of "by knife" written on the car door of Bryan Hartnell on September 27th 1969.  

The Zodiac Killer added the "August" murders into his Dripping Pen card on November 8th 1969, followed by a drawing entitled "The Bleeding Knife of Zodiac" on December 16th 1969. This fascination with knife murders likely continued on December 20th 1969 with his address to Melvin Belli. In this communication he used very similar wording connected to another knife murder on December 10th 1945. We know the Zodiac Killer kept abreast of the news, so did he read something in the newspapers on December 10th 1969, the anniversary of the murder of Frances Brown at her 3941 North Pine Grove apartment in Edgewater, Chicago? She had been savagely stabbed, with the knife left protruding from her neck, along with a bullet wound to her head.. Near her body, written in lipstick on the apartment wall, were the words "For heavens Sake catch me Before I kill more I cannot control myself". The Zodiac Killer wrote in the Melvin Belli letter "I will loose all controol of myself. Please help me. I can not remain in control for much longer". This is what makes the Robert Salem murder so very interesting.

Just shy of four months later (just prior to April 20th 1970), Robert Salem too was discovered murdered in his apartment, the victim of a repeated stabbing using a long-bladed knife. Just like the murder of Frances Brown (attributed to William Heirens), the murderer had written a "red message" (this time in blood) on the apartment wall of Robert Salem. It read "Satan Saves Zodiac" and was accompanied by the drawing of an Ankh, which was commonly held in the hands of ancient Egyptian deities (or being given by them to the pharaoh), to represent their power to sustain life and to revive human souls in the afterlife.

If this was a copycat as police suspected, then we would have to conclude that the perpetrator (who didn't write the Belli letter) made the connection to the Frances Brown murder, which was concealed in the wording of the December 20th 1969 letter, and recreated her murder scene in the apartment of Robert Salem, with the Zodiac pseudonym attached. Or, the copycat inadvertently created the murder scene of Frances Brown in the 745 Stevenson Street, San Francisco apartment of Robert Salem, without any prior knowledge of the hidden meaning in the Melvin Belli letter, and just so happened to write the Zodiac pseudonym. The third option, is that the Zodiac Killer was responsible for the stabbing of Robert Salem and was deliberately linking the hidden message in the Melvin Belli letter to his latest murder, playing games with the police along the way. The final option may be that no connection exists between the wording on the Melvin Belli letter and the murder of Frances Brown. It is just another case of seeing things that aren't there.

There appears a close correlation in the language the Zodiac Killer adopted in his communications, to the newspaper articles he read. But how much of this is a simple case of scanning old newspapers and forging links between the words used in each?

Something triggered the Zodiac Killer to begin a victim count on November 8th 1969, when he chronologically laid out the months of his murders in the following fashion: Des July Aug Sept Oct = 7". The Zodiac Killer, annoyed by the lack of front page coverage after his three murders and three cryptograms back in August, switched to murder by knife at Lake Berryessa after reading the extensive front page coverage of the August 3rd 1969 Snoozy & Furlong stabbings in the San Francisco Chronicle. His declarative statement of "by knife" on the car door at Lake Berryessa, a defiant response to this lack of front page coverage. The Zodiac Killer was effectively stating "do I now get front page coverage". The San Francisco Chronicle made the connection Zodiac had hoped for, by eventually linking him to the Snoozy & Furlong murders. By confronting Bryan Hartnell and Cecelia Shepard at Lake Berryessa with a bladed instrument, he was prompting the newspapers to forge a link between the September 27th 1969 and August 3rd 1969 attacks.

On October 19th 1969, the San Francisco Examiner sent a message to the Zodiac Killer, stating "Five people are dead. Let there be no more killings. Police say you are intelligent. If you are, then listen to reason. You are being hunted everywhere in the state, and nation. You are alone in this world. You can share your secrets with no one. No friend can help you. You are as much a victim of your crimes as those whose lives you snuffed out. You cannot walk the streets a free man. There is no safety for you, anywhere. And you will be caught, there is no doubt. You face life as a hunted, tormented animal - unless you help yourself. We ask that you give yourself up to the Examiner. We offer you no protection, and no sympathy. But we do offer you fair treatment, the assurance of medical help and the full benefits of your legal rights. And we offer to tell your story. Why have you killed? How has life wronged you? Call the City Editor of the Examiner any time, day or night. The telephone number is (415) 781 24 24. Call collect. Your call will not be traced".

There are several things in this article that may have resonated with the Zodiac Killer, ultimately inspiring his choice of wording within the Dripping Pen card on November 8th 1969. The Zodiac Killer had urged the police and newspapers to make the connection to the Snoozy & Furlong murders, by not only switching his mode of attack on September 27th 1969, but by also adding the additional text of "by knife" on the car door. The San Francisco Examiner stated "Five people are dead. Let there be no more killings". On November 8th 1969, the Zodiac Killer would declare seven victims in defiance, by chronologically listing the months of his attacks: Des July Aug Sept Oct = 7". He was effectively saying "do you get the message now".

The San Francisco Examiner article continued by adopting the isolationist language of "You are being hunted everywhere in the state, and nation. You are alone in this world. You can share your secrets with no one. No friend can help you". This statement may have also struck a nerve with the Zodiac Killer, who replied in the Dripping Pen card with "I get awfully lonely when I am ignored, so lonely I could do my thing." The Examiner article continued: "There is no safety for you, anywhere. And you will be caught, there is no doubt". On November 9th 1969 in the Bus Bomb letter, the Zodiac Killer reiterated the words "The police shall never catch me, because I have been too clever for them", also reminiscent of the wording used by the sadistic caller to Daniel Williams during this period, by way of “I’m too smart for them" when referring to the police over the phone. It is also unsurprising that the Zodiac Killer would respond to "And you will be caught, there is no doubt", with "There's no doubt I will do my Thing!" on November 21st 1969, while providing yet another code.

One month after the November 21st 1969 letter to the San Jose Police Department, the Zodiac Killer wrote to Melvin Belli at 1228 Montgomery Street in San Francisco. The San Francisco Examiner article stated "No friend can help you. You are as much a victim of your crimes as those whose lives you snuffed out. You cannot walk the streets a free man. There is no safety for you, anywhere. And you will be caught, there is no doubt. You face life as a hunted, tormented animal - unless you help yourself. We ask that you give yourself up to the Examiner. We offer you no protection, and no sympathy. But we do offer you fair treatment, the assurance of medical help".

Thrice the San Francisco Examiner mentioned the word "help" in respect to the Zodiac Killer, so did he ultimately respond in mocking fashion four times via Melvin Belli? The Zodiac Killer adopted a pleading tone in the December 20th 1969 letter, stating "The one thing I ask of you is this, please help me", along with "I cannot reach out for help because of this thing in me wont let me". the brief "Please help me", and "Please help me I can not remain in control for much longer". The Zodiac Killer also continued the theme of a "thing" in three of the four communications.

Is this a case of "seek and you will find" with respect to the newspapers and language used by the killer, or did he feed off the newspapers and deliberately engineer his communications as a direct response to the articles he read? I will let you decide

The brutal stabbing and murder of Robert Michael Salem on April 15th 1970 is so much more compelling as a potential Zodiac crime compared to other outlier murders linked to the Bay Area killer. I will do a brief run through of what we know so far, before adding a little more to the equation. This additional information will include the Good Citizen letter mailed to Sergeant John Lynch on October 7th 1969, just four days before the murder of Paul Stine in Presidio Heights. 

The Melvin Belli letter mailed on December 20th 1969 appeared to invoke the Frances Brown murder scene on December 10th 1945 at her 3941 North Pine Grove apartment in Chicago. She had been stabbed multiple times, with the knife discovered protruding from her neck. Her killer (supposedly William Heirens} had left an ominous message written in red lipstick on the wall of her apartment stating "For heavens Sake catch me Before I kill more. I cannot control myself". The Zodiac Killer had written on the Melvin Belli letter "I will loose all controol of myself. Please help me. I can not remain in control for much longer". The message on the wall of Frances Brown's apartment was written above a table lamp. It was therefore uncanny that the Zodiac Killer's next correspondence arrived on April 20th 1970, on the same day that the San Francisco Chronicle published details regarding the murder of Robert Salem, in which the killer wrote a message on the wall in blood -. and Robert Salem was a lamp designer, having them displayed in museums and art fairs around the world. If the statement of "I hope you have fun trying to figgure out who I killed" on the April 20th 1970 letter wasn't Robert Salem, it is extremely fortunate timing off the back of the Melvin Belli letter four months previously.  

For a copycat killer to read into the wording contained within the Melvin Belli letter, authenticated as Zodiac correspondence, and place Zodiac on the wall of Robert Salem's 745 Stevenson Street, San Francisco apartment in similar fashion to the Frances Brown murder scene, would take a special form of insight. Unless of course, it was the Zodiac Killer who murdered the lamp designer. This drives to the heart of the question - of whether the Zodiac Killer had crossed paths with Robert Salem in the preceding months to his murder - and was specifically targeted by the Bay Area murderer. By murdering somebody of relative acclaim and scrawling his pseudonym on the wall, he could certainly expect front page coverage in the Chronicle. We have speculated that the Zodiac Killer had a penchant for the dramatic, with his references to The Mikado, his Lake Berrryessa costume and the style of his communications. He certainly appeared to have artistic leanings. If the Zodiac Killer had befriended Robert Salem, then it may have come through a mutual love of the arts, either through a museum, the theater or an arts and crafts fair. 

The San Francisco Chronicle article on April 20th 1970 stated that "Salem's designs have been exhibited in England, Japan and Russia under State Department cultural exchange programs. Until last year (1969) he had been the lighting designer for restoration of the historic Haslett Warehouse on Hyde Street". In fact, the address is given as 680 Beach Street at Hyde, Russian Hill, San Francisco. It is situated just 1.5 miles from where Paul Stine began his fateful journey on October 11th 1969. Here is the view of the Haslett Warehouse from 700 Beach Street, just across the intersection of Hyde Road.  

"During the 1960s, California was the site of many outdoor art fairs, which nurtured a culture of independent artists and craftspersons. At this time there was an effort to sell crafts on the sidewalks of the liberal Haight-Ashbury neighborhood of San Francisco. Artists and street performers who illegally set up in public areas were frequently harassed and arrested by the police. In the 700 block of Beach Street adjacent to Victorian Park and near Fisherman's Wharf, between 15 and 25 artists would set up their displays and use lookouts to alert them to the arrival of the police". Wikipedia. This certainly would have attracted the attention of somebody like Robert Salem, who was working at the Haslett Warehouse just yards away. Is it possible the Zodiac Killer crossed paths with Salem at an art and crafts fair such as this? I wouldn't normally attempt to use such a speculative link but for October 7th 1969 Good Citizen letter, possibly mailed to Sergeant John Lynch from the Zodiac Killer.

With immense gratitude to Rubislaw32,  this correspondence was mailed on October 7th 1969, just two months after the "concerned citizen" card and four days before the murder of Paul Stine in Presidio Heights on October 11th 1969. It has been dubbed the "good citizen" letter, postmarked San Mateo and signed ''A good citizen", with a footnote from Sergeant John Lynch. It stated that the writer has a strong feeling of ESP. While having these feelings, the writer writes with a pencil. On occasion, while thinking of the code letters, the pencil wrote: ''Go to 56 Beach Street. I get the name Jerry, perhaps he knows people or his name is XXXXXXX''. This letter referenced Beach Street, where Robert Salem worked during the latter months of 1969. So we have four intersecting points of interest - an art and crafts fair on Beach Street, where artist Robert Salem likely worked during the mailing of the October 7th 1969 "Beach Street" letter, with Paul Stine picking up his killer just 1.5 miles south, only four days later. It may not be compelling, but the possibility exists that the Zodiac Killer crossed paths with the lamp designer before April 15th 1970 and murdered him at his 745 Stevenson Street apartment, all while inspired by the December 20th 1969 Melvin Belli letter some four months earlier.

In previous articles we have discussed the Zodiac shift from gun to knife at Lake Berryessa, his claim to be responsible for the San Jose knife slayings on August 3rd 1969, the "Bleeding Knife of Zodiac" correspondence and the possibility he was referring to the Reet Jurvetson murder as victim number eight. Then came the Melvin Belli letter on December 20th 1969, the tone of which bore similarities to the Frances Brown murder scene on December 10th 1945 at her 3941 North Pine Grove apartment in Chicago. She had been stabbed multiple times and the knife was discovered protruding from her neck. Her killer had left an ominous message written in red lipstick on the wall of her apartment stating "For heavens Sake catch me Before I kill more. I cannot control myself". The Zodiac Killer had written "I will loose all controol of myself. Please help me. I can not remain in control for much longer". We know that the Zodiac Killer had a propensity for plagiarism, often using lines from The Mikado, along with his reference to The Most Dangerous Game - both of which dated back to 1885 and 1924 respectively. Therefore, it shouldn't be too much of a surprise that he would again bring up another knife murder, this time from 24 years prior. The question is, whether anybody in the four subsequent months to December 20th 1969 could reasonably have been expected to make the connection between the Melvin Belli letter wording and the murder of Frances Brown in 1945, other than its designer?

William Heirens was convicted in the murders of Frances Brown, Josephine Ross and 6-year-old Suzanne Degnan, who was savagely killed and dismembered. This is what makes the murder of Robert Michael Salem on April 15th 1970 so very interesting. He was brutally stabbed in his 745 Stevenson Street, San Francisco apartment, with the newspapers reporting that "the killer had apparently tried to decapitate his victim and when that failed, cut off Salem's left ear". Suzanne Degnan's killer had severed her head, which was ultimately found in a sewer one block from her residence. The murderer of Robert Salem had also written on the wall of the apartment above his body, this time with "red blood" as opposed to "red lipstick", but accompanied by the wording "satan saves" and "Zodiac". The writing was adorned with the drawing of an Ankh - it was commonly held in the hands of deities, or being given by them to the pharaoh, to represent their power to sustain life and to revive human souls in the afterlife.

This crime scene coming just under 4 months after the Melvin Belli letter, which didn't overtly mention the Frances Brown crime scene, but disguised it within the context of the wording chosen. The murder of Robert Salem at 745 Stevenson Street just 1.6 miles from the 1228 Montgomery Street residence of prominent attorney Melvin Belli, 821 meters from the Chronicle offices and 0.8 miles from Union Square (the pick up point of Paul Stine's fateful taxicab journey). Could a random killer have engineered such a crome scene at 745 Stevenson Street by reading into the disguised writings of the Zodiac Killer 4 months earlier, when it is most likely not many had made the connection to the Frances Brown murder scene over two decades earlier? Or is it more likely that the Zodiac Killer murdered Robert Salem with multiple knife wounds (just 1.6 miles from the Belli residence), scrawled "Zodiac" on the wall in "red writing" and attempted to decapitate his victim in similar fashion to that of Suzanne Degnan?

An article describing the murder of Robert Salem featured in the San Francisco Chronicle on April 20th 1970, just hours before the Zodiac Killer mailed his '13 Symbol' cipher to the newspaper, stating "I hope you have fun trying to figgure out who I killed"​​​. After four months of silence, one could easily come to the conclusion that this was no coincidence, especially when we draw a parallel from the "satan saves" message on the wall in blood, to the 888 circled in the '13 Symbol' cipher. This figure representing Jesus or Christ the Redeemer in Christian numerology. Throw in the "Ankh" and "afterlife", and the picture becomes clearer. The massive parallels of the Robert Salem murder to the Frances Brown murder are clear to see - but could a killer pretending to be Zodiac have worked all this out from the innocuous pleas for help in the Melvin Belli letter months earlier? The Zodiac Killer (referring to the murder of San Francisco police officer Brian McDonnell) stated that "I hope you do not think that I was the one who wiped out that blue meannie with a bomb at the cop station. It just wouldn't doo to move in on someone else's teritory". But was 745 Stevenson Street, just 1.6 miles from the Melvin Belli residence and 0.8 miles from Union Square, more likely the territory he operated within - and did so on April 15th 1970?   

The first coverage of the Salem murder was in the morning edition of the San Francisco Chronicle on April 20th 1970, so did the Zodiac Killer have time to construct a letter that included a cipher, bus bomb diagram and a reference to the murder of San Francisco police officer Brian McDonnell on February 16th 1970, who suffered devastating and sadly fatal injuries two months earlier, when a bomb packed with fence staples exploded on an outside ledge of Park Police Station in the Upper Haight neighborhood? The Zodiac Killer would had to have rushed this letter in order for it to be mailed and postmarked the same day. Unless, he had prepared it days earlier, just after the murder of Robert Salem and deliberately timed to coincide with the San Francisco Chronicle newspaper coverage. 

The police claimed that the "killer was not Zodiac", but with the parallels drawn from the authenticated Melvin Belli letter regarding the murder of Frances Brown - that a copycat would have been hard pushed to extrapolate - does this make the assertion that this was not a Zodiac crime by police, a rather over-confident statement just five days after the murder?  

On October 20th 1969, nine days after the murder of Paul Stine in Presidio Heights, somebody made a threatening phone call to the Palo Alto Times newspaper saying he intended "to pick the kids off as they get on the school bus". The San Bernardino County Sun reported on the threat, stating "Patrol cars convoyed school buses around Palo Alto yesterday after a telephoned murder threat by a man claiming to be the Zodiac Killer of five persons. The weird slayer who signs himself "The Zodiac" made a similar threat in a letter to the San Francisco Chronicle last week after the Oct 11 shooting of a taxi driver. The district transportation supervisor said an armed guard might ride with each of the system's 25 buses. Officers in Napa and Vallejo, areas of the first three murderous attacks, some 45 miles north of Palo Alto, have been convoying police officers. Palo Alto Police Chief William Hydie called the new threat "extremely serious," but warned against over reaction to what might be a crank call".

On November 8th 1969, the Zodiac Killer mailed the 'Dripping Pen' card and 340 cipher to the San Francisco Chronicle claiming the "Aug" murders of Debra Gaye Furlong (14) and Kathy Ann Snoozy (15), who were found brutally stabbed on August 3rd 1969 in the Bay Area of San Jose.

On November 21st 1969, somebody claiming to be the Zodiac Killer wrote to the San Jose Police Department​ threatening the life of a widow, accompanied by the words "There's no doubt I will do my Thing". The brief text in the letter clearly contained enough information for police to identify the woman and implement 24-hour surveillance on her residence.

On December 7th 1969, a letter was mailed from Fairfield stating "I just need help. I will kill again, so expect it any time the will be a cop".

On December 16th 1969, another letter arrived from Fairfield threatening to kill "government life" and "cops" in Sacramento, Fairfield, Napa, Vallejo, Oakland, San Francisco and San Jose. A future geographic profiling technique was applied to the locations in which he 'threatened murder' (as detailed in the Fairfield letter), and noted that "Interstate 80 begins at an interchange with U.S. Route 101 (US 101) in San Francisco, and then crosses the San Francisco–Oakland Bay Bridge into Oakland. It then heads northeast through Vallejo, Fairfield, Sacramento, and the Sierra Nevada mountains before crossing into Nevada". The idea was to identify the areas the Zodiac Killer was prepared to target, based on their accessibility to him using a main commuter route he regularly traveled. If he regularly used the I-80 for his profession, then six of these seven destinations are directly passed by the I-80, with Napa only a few miles off route.

On December 19th 1969, somebody claiming to be the Zodiac Killer again threatened cops, making a phone call to Sergeant Robert Rengsdorff of the San Jose Highway Patrol (see article above), stating "I am going to kill five of you officers and a family of five between now and Monday". This threat towards San Jose police and a family of five was issued on a Friday, exactly as was the November 21st 1969 letter, mailed to San Jose police threatening harm on a widow. After the threat on the widow was thwarted by 24-hour police surveillance on her residence, was this the response, to once again instigate fear in the San Jose community? Were the widow and 'family of five' of the same residence? We know he was threatening the lives of numerous police officers, but the threat on five members of a family appears rather specific.           

On December 20th 1969, the Zodiac Killer mailed the 'Melvin Belli' letter containing a piece of murdered Paul Stine's shirt, effectively proving the author was the murderer of the taxicab driver on October 11th 1969. This letter mimicked the December 7th 1969 Fairfield letter by stating "please help me", which in some way helps to authenticate both Fairfield letters not released to the newspapers.

​The purpose of this article is to show the targeted areas of the Zodiac Killer (if responsible for these letters and phone calls) from the standpoint of geographic profiling. These events spanned from the October 11th 1969 murder of Paul Stine, to the mailing of the 'Melvin Belli' letter on December 20th 1969 (71 days). The areas shown in red above, highlight the locations the Zodiac Killer targeted by murder, proposed murder, as well as by his threatening phone calls and letters - and they are all connected by one direct route of travel.

During these 71 days in October, November and December the Zodiac Killer focused his attention on Sacramento, Fairfield, Vallejo, Oakland, San Francisco, Palo Alto and San Jose. Interstate 80 and U.S. Route 101 provide one seamless journey from Sacramento to San Jose. Was the Zodiac Killer a traveling salesman which took him through each of these locations - and therefore he had a familiarity with? Do these commuter route tell you anything about his home residence during this time period? 
When you commit, or intend to commit these acts, accessibility to and from a main commuter route could be invaluable.

Equidistant (as the crow flies) to Sacramento and San Jose is the waterfront city of Vallejo, believed by many to be the home residence of the Zodiac Killer. It is 53 miles from Sacramento and 57 miles from San Jose. The Springs and Tuolumne payphone, where Zodiac placed a call to police dispatcher Nancy Slover on the morning of July 5th 1969, sits 728 metres from Interstate 80.

On Monday October 12th 1970 the San Francisco Chronicle ran an article entitled Gilbert and Sullivan Clue to Zodiac. Just two weeks later, the Zodiac Killer would respond when he mailed the Halloween Card to Paul Avery, a prominent San Francisco Chronicle reporter. This card, containing two skeletons, opened with the phrase "I feel it in my bones, you ache to know my name. And so I'll clue you in..' This on the face of it seemed like a direct response to the Chronicle article, but what clue was the Zodiac prepared to give us in this card regarding his identity or name. Before we tackle this problem, we shall fast forward to the Exorcist Letter, mailed to the Chronicle on January 29th 1974 and investigate any possible clues within this correspondence. This first part has been covered previously, however, this will be expanded upon as we delve a little deeper.
The Exorcist Letter appeared a curious blend of two productions; The Mikado (1885), a satirical portrait of Victorian England, and the horror classic The Exorcist (1973), ironically labeled "the best saterical comidy that I have ever seen" by the Zodiac Killer. The Exorcist Letter appears a mismatch of genres, an unholy alliance of mixed messages, unless of course it was designed this way to provide us with a hidden clue to his identity or name.   

On the left is an excerpt from the Exorcist Letter. 
After a line such as "Signed, yours truley", one would expect the sender to provide us with a name, yet here the Zodiac Killer gives us a line from The Mikado's On a tree by a river, part of Act Two. Is his name concealed within these lines? In the article 'The Best Saterical Comidy,' this idea was explored. The name William can be abbreviated to Will, Bill, Billy, Willy, or Willie. It can be seen that these lines contain the names 'Bill and Will' several times. This of course is meaningless on its own, until you wrangle with the unusual alliance of The Exorcist and The Mikado. 

The Exorcist is an American horror film released in 1973, directed by William Friedkin and adapted for screenplay by William Peter Blatty, based on his 1971 book. The Mikado was created by Gilbert and Sullivan, however, one half of the duo was Sir William Schwenck Gilbert, to effectively give us the three William's in the excerpt above, and tempt us with the phrase "Signed, yours truley, William".  The inspiration for William Peter Blatty's novel The Exorcist (1971) was the real life exorcism of Roland Doe, a 13-year-old Maryland boy, in 1949. Father William S. Bowdern, S.J. was central to this exorcism, assisted by Walter Halloran and William Van Roo, a third Jesuit priest, bringing our total to five.

​In the San Francisco Chronicle article Gilbert and Sullivan Clue to Zodiac, Paul Avery wrote "Sheriff's detective sergeant Kenneth Narlow of Napa County has fruitlessly followed up another 900 tips to Zodiac's identity since September 27th 1969". Did the Zodiac take this line and incorporate it into the Halloween Card, using the pumpkin fruit to effectively reveal his identity, by deliberately placing the pumpkin over the groin and then removing it, to expose his identity. The groin becomes fruitless, yet reveals a name? I'm afraid you've guessed it - Willy. While this is highly improbable, the Zodiac Killer did present a rather immature element in much of his correspondence. In an attempt to reinforce this identity we shall proceed. The Halloween Card is obviously a reference to the Western Christian celebration of All Hallows Day on October 31st, hence the use of the spiders web, skeletons and pumpkin within the card. The most notable addition to the card was the pumpkin, so other than its deliberate positioning, has it any further significance to the Zodiac Killer's identity? The pumpkin itself is carved out on Halloween to create a spooky or ghostly face and lit on the inside to create a menacing glowing effect. This is termed a 'Jack o' lantern' or 'Will o the wisp' - an atmospheric ghost light seen by travelers at night.    

The Zodiac Killer placed numerous eyes on the Halloween Card, accompanied by the words "peek-a-boo you are doomed", wrapped around the knothole in the tree. This, on the face of it, appeared a veiled threat towards San Francisco Chronicle reporter Paul Avery, but was it yet another clue to his identity?
 
​'Blind Bat', a member on the Zodiac Killer Site forum displayed an interesting connection to the Halloween Card, involving the "peek-a-boo" phrase the author added to the greeting card. The picture on the right demonstrates this perfectly with the Zodiac-like letter K, with the eyes and eyelashes eerily similar to the depiction on the Halloween Card itself. ​William V Peekaboo Pennington Senior was a San Francisco private detective, described as a cattle man, private investigator, theater owner, building contractor, oil man and member of the Eastern Star, a freemasonry related order established in 1850 by Rob Morris. He moved to San Francisco in 1924 and performed investigative duties for prominent lawyers and attorneys, including Melvin Belli, who became closely embroiled in the Zodiac Killer case. The Halloween Card provides us with two full, and two abbreviations of William, when we consider the following.

​The Halloween Card is the only time the Zodiac Killer used the letter Z on his correspondence, other than the Cheri Jo Bates letters of 1966, which has still not been definitively linked to the Bay Area murderer. He places the letter Z on the envelope and the inside of the card - but in addition to this - the Zodiac Killer places a Zorro style mask on the skeleton. Is this a further clue? Had the Zodiac spent his formative years in the 1950s, Zorro would have been a high profile television series, made into two Walt Disney films, The Sign of Zorro (1958) and Zorro, the Avenger (1959). The Disney television series ran from 1957 to 1959, and this, along with the two movies starred Guy Williams.  
  
Revisiting the subject of Melvin Belli, the Zodiac Killer wrote a personal correspondence to the prominent lawyer on December 20th 1969. In this correspondence he stated "I will loose all controol of myself and set the bomb up. Please help me I can not remain in control for much longer". This phrase is remarkably similar to a message scrawled on the wall of murder victim Frances Brown, who was discovered on December 10th 1945 at her 3941 North Pine Grove apartment, in Edgewater, Chicago. She had multiple knife wounds, with the actual knife found protruding from the victim's neck, along with a bullet wound to the head. The killer had left a calling card, in the form of a message written in lipstick on the wall. See here. It said: "For heavens Sake catch me Before I kill more. I cannot control myself". The Zodiac Killer wrote (edited) "I will loose all controol of myself. Please help me. I can not remain in control for much longer".  The killer William Heirens, known as the 'Lipstick Killer', was convicted of the murders of three females over a seven-month period. Was the letter mailed to Melvin Belli a plea for help or just another subtle clue to his identity.

Paul Avery extensively covered the Patty Hearst affair, along with San Francisco Chronicle reporter Tim Findley, something the Zodiac was unlikely to miss. The Zodiac Killer has been credited with the 'SLA Letter' mailed on February 3rd 1974, the day before the kidnapping of Patty Hearst by the Symbionese Liberation Army on February 4th 1974. There are two links here, in that Patty Hearst was the granddaughter of American publishing magnate William Randolph Hearst, who gained control of the San Francisco Examiner from his father. But more importantly, the Symbionese Liberation Army (SLA) leaders were Donald De Freeze and William Harris. One of its founding members was Willie Wolfe. 

​In the article 'Gilbert and Sullivan Clue to Zodiac', Paul Avery wrote "Zodiac is still at large today. And he is now claiming he has murdered thirteen persons. Homicide detectives who've been hunting Zodiac for nearly two years frankly admit he is as much an enigma now as he was on December 20th 1968, when he chalked up his first two victims". In chalk-like writing, the Zodiac would now be claiming a potential fourteen victims in the Halloween Card - but was it revealing a lot more than initially thought?

The Little List letter mailed on July 26th 1970 heavily featured two portions of The Mikado. The seventh line of Mikado Act One Part 5a  As some day it may happen reads "All children who are up in dates, and floor you with 'em flat". The Zodiac Killer paraphrases this verse to "All children who are up in dates and implore you with im platt". It could simply be that he was attempting to write the letter F, and accidentally formed the letter P - but if not.........

We have spent nearly fifty years studying the Zodiac Killer, delving into the mind of a murderer and attempting to unlock the driving force behind his reign of terror to uncover the reason behind the madness - and we are by no way short of ideas. As many observers have pointed out, our killer may have had a military connection, had theatrical links either professionally or personally, including an oriental link, born out by three references to the Mikado and the symbols portrayed on the Exorcist Letter, as well as an affinity towards movies and a penchant for the cryptic. However, on the flip side he portrayed an illiterate, egotist with a flair for a lack of subtlety, displayed in unstinting fashion in his 408 Cipher, in which he states candidly "to kill something gives me the most thrilling experience it is even better than getting your rocks off with a girl". The thing is, he may have been telling the truth, if the San Francisco Chronicle reporter Paul Avery was to be believed.

On October 18th 1969 he ran a piece in the San Francisco Chronicle describing the Zodiac Killer as a 'latent homosexual'. Under the banner Zodiac-Portrait of the Killer  he stated "The killer of five who calls himself 'Zodiac' is a clumsy criminal, a liar and possibly a latent homosexual". How close this description is to reality is open to question, but it has some legs and is worth investigating. The Zodiac Killer addressed Paul Avery personally when he sent the Halloween Card on October 27th 1970 approximately one year after this article was written - and bearing in mind the killer's ability to reduce everything to base level and the aforementioned characteristics he displayed in his missives, this is how we shall approach this card.        

Two notable features of this card were the two skeletons, one of which had a pumpkin placed over the genital area. It was after all four days before Halloween, so the pumpkin and skeletons were not unusual - but why would the Zodiac Killer choose a pumpkin, of all the things he could have chosen, and in particular, place it in such a fashion. The Zodiac Killer also underlined the 'lav' in the misspelled reporter's name Paul Averly. These two features of the card, along with the phrase 'peek-a-boo', implied a suggestion of something hidden.
 
Some Zodiac researchers have explored the possibility the Zodiac was of English origin, on account of his word usage, such as 'shall', infrequently used in American English, but by the same token a word frequently used by thespians. Peek-a-boo  
is known as Peep-bo in British culture and is the act of concealing ones face behind the hands or other object, before suddenly appearing back into view and uttering the words peek-a-boo or peep-bo. It can be seen in Wikipedia that many variations involve trees, similar to the depiction on the Halloween Card, where 'Hiding behind that tree' is added. See here. Whether or not it is a significant phrase by the Zodiac Killer is open to question, but Peep-Bo is a character that features during Act I of The Mikado.

The eyes peering from the tree, peek-a-boo and the hidden gender, may just have been the start of a form of 'toilet humor' backlash or closet acceptance that the Paul Avery reference to Zodiac possibly being a 'latent homosexual' had been officially noted. After all 'lav' is a colloquialism used in English speech for lavatory or 'water closet'. A 'closet homosexual' is used for people who have not disclosed their sexual orientation or gender identity, and ties in nicely with the English phrase 'skeleton in the closet', coined in the 19th century, a colloquial phrase and idiom used to describe an undisclosed fact about someone which, if revealed, would have a negative impact on perceptions of the person.

​Falling back to the theatrical connection and The Mikado, 'Skeleton in the Closet' was a 1965 Japanese 'Pink Film', also called 'Secrets Behind the Wall'. A 'Pink Film' deals with Japanese theatrical films of nudity, almost exclusively shot on 35mm film - but in order to circumvent censorship restrictions, Japanese directors carefully positioned props over the actors private parts, although one doubts a pumpkin found its way on to set very often. Incidentally pumpkin seeds have long been used in parts of Asia for boosting sexual performance and prostate health.

The Zodiac Killer is indelibly linked to San Francisco. Most of his mailings were to the Chronicle, along with his final confirmed murder, a marked deviation from his previous attacks on lone couples across the bay. Paul Stine was believed to have picked up his final passenger from the theater district near the intersection of Mason and Geary Street, while some believe it may have been around the area of Nob Hill or the Tenderloin District.

San Francisco in the 1960s had overseen a marked change - the Castro District being one - having transformed from a working class area to a prominent symbol of the lesbian, gay, bisexual and transgender movements. After World War II many military personnel courted the area, unwilling to return to a life incompatible with homosexuality and other forms of behavior, and areas like the Tenderloin and Castro Street became the home to many gay bars and sex clubs. As early as 1963 Castro Street opened its first gay bar, the 'Missouri Mule'. One such person was gay activist and entertainer Jose Sarria, who himself had served in World War II, but continued to fight against police harassment against not only gay people, but gay establishments as a whole, having performed in the 'Black Cat Bar' at 710 Montgomery Street, a north-south thoroughfare. 

The idea of a hidden body was extensively used in the Gothic novels of the Victorian period. Edgar Allen Poe was best known for his tales of mystery and the macabre, and one such example was this extract from 'The Black Cat' in 1845. "Gentlemen, I delight to have allayed your suspicions", and here, through the mere frenzy of bravado, I rapped heavily upon that very portion of the brick-work behind which stood the corpse of the wife of my bosom. The wall fell bodily. The corpse, already greatly decayed, stood erect before the eyes of the spectators". It has been suggested that the phrase 'skeleton in the closet' derives from the era of the notorious body snatchers, prior to 1832, when the UK's Anatomy Act allowed the more extensive use of corpses for medical research. The theory goes that, in a scenario similar to that of the concealment of Catholic priests in priest holes in domestic houses in Elizabethan England, doctors would conceal in cupboards the illegally held skeletons they used for teaching. Although there's no evidence at all to corroborate that theory. Concealed skeletons are occasionally found walled-up in houses, but they are usually those of unwanted infants. See here. 

In the early years of San Francisco it was against the law for men to dress up in women's clothing, but an exception was made for one night only on Halloween, a pagan celebration that would become the adopted day for gay celebrations. Sarria encouraged patrons to be as open and honest as possible, exhorting the clientele, "There's nothing wrong with being gay–the crime is getting caught," and "United we stand, divided they catch us one by one."  At closing time, he would lead patrons in singing "God Save Us Nelly Queens" to the tune of "God Save the Queen". Sometimes he would take the crowd outside to sing the final verse to the men across the street in jail, who had been arrested in raids earlier in the night. Raids on gay bars were routine, with everyone inside the raided bar taken into custody and charged with such crimes as being "inmates in a disorderly house". Although the charges were routinely dropped, the arrested patrons' names, addresses and workplaces were printed in the newspapers. When charges were not dropped, the arrested men usually quietly pleaded guilty. Sarria encouraged men to plead not guilty and demand a jury trial. Following Sarria's advice, more and more gay men began demanding jury trials, so many that court dockets were overloaded and judges began expecting that prosecutors have actual evidence against the accused before going to trial. One favored harassment technique, employed especially on Halloween after midnight, was to arrest drag queens under an old city ordinance that made it illegal for a man to dress in women's clothing with an "intent to deceive". In consultation with attorney Melvin Belli, Sarria countered this tactic by distributing labels to his fellow drag queens (hand-made, in the shape of a black cat's head)  that read "I am a boy". If confronted, the queen would simply display the tag to prove that there was no intent to deceive. Sarria's actions helped bring an end to Halloween police raids  Excerpt from Wikipedia.

The Zodiac Killer certainly seemed to have many things in common with San Francisco. Is it possible he was a 'latent homosexual' as described by Paul Avery, who harbored a resentment against police and officialdom, strikingly evident in his correspondence to the San Francisco Chronicle, not to mention his linkage to Melvin Belli through the 'Call to Chat Show' spectacle and the Dragon Card mailed on April 28th 1970 calling for people to wear his nice Zodiac buttons - possibly on their lapels, similar to the hand-made labels of protest above. And finally the Melvin Belli Letter mailed on the anniversary of Lake Herman Road, just before Christmas.  

Halloween in the Tenderloin grew in the early 1960s with the growing LGBT community and welcomed tourists – who many of the prostitutes and hustlers relied upon for income. By the late 1960s, a major celebration area during Halloween was along Grant Avenue in North Beach, on which there were many gay bars in the late 1960s between Broadway and Union. Excerpt from Wikipedia.

​Melvin Belli was a flamboyant showman and prominent attorney summoned to appear on the Jim Dunbar Chat Show supposedly by the Zodiac Killer, along with Francis Lee Bailey, well known for his involvement in the Patty Hearst SLA trial - something again the Zodiac seemed at pains to point out. Melvin Belli was famous for his use of 'Elmer' the skeleton, which he often used in his medical malpractice suits. After winning a court case, Belli would raise a Jolly Roger flag over his Montgomery Street office building in the Barbary Coast district of San Francisco (which Belli claimed had been a Gold Rush-era brothel) and fire a cannon, mounted on his office roof, to announce the victory and the impending party. See Wikipedia

The Dragon Card mentioned above contained these lines "If you dont want me to have this blast you must do two things. Tell everyone about the bus bomb with all the details. I would like to see some nice Zodiac buttons wandering about town. Everyone else has these buttons like, black power, melvin eats bluber, etc. Well it would cheer me up considerably if I saw a lot of people wearing my buton. Please no nasty ones like melvin's. Thank you". The card used was a Jolly Roger greetings card.- and we know that a Jolly Roger is a traditional English name used to refer to the flag depicting part of a skeleton and displayed on pirate ships. The links are there, but are they interconnected? Was the Halloween Card a form of base subtle humor, along with the Dragon Card that implied the Zodiac Killer did indeed harbor a deep felt resentment, against not only Paul Avery and the San Francisco Chronicle, but also the police in general - not only for the reasons we have become accustomed to, but for reasons far more personal to our killer, leaving us to wonder if the 'skeletons in the closet' may have been rattled loose just slightly and the 'mask' of the Zodiac Killer may one day fall to reveal his true identity.
