Despite some interesting avenues having been pursued in the search for "Jerry" in the "Good Citizen" letter mailed on October 7th 1969, it is clear that the cryptic nature of the language adopted in this communication has made it difficult to interpret its meaning. Both the August 10th 1969 "Concened Citizen" card and October 7th 1969 "Good Citizen" letter were addressed to Sgt John Lynch of the Vallejo Police Department, both utilized the word "citizen" in the signature, both used the word "name" twice in the message, with the "Good Citizen" author referring to the "code letters", which can only be reasonably assumed to be the letters mailed to the Vallejo Times-Herald, San Francisco Chronicle and San Francisco Examiner on July 31st 1969 (and the 408 cipher).  A footnote from Sergeant John Lynch concerning the "Good Citizen" letter 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''. 

The last major article featuring Sgt John Lynch and the 408 cipher, entitled "A Name in Murder Cipher", suggested the name "Robert Emmet the hippie" as one possibility, despite it being too long to accommodate the 18 unsolved characters at the foot of the 408 cipher. At the end of the August 12th 1969 article, Sgt John Lynch stated "We aren't sure Robert Emmet is who we are looking for. Maybe he'll send another letter and let us know". This request from Sgt John Lynch was specifically about the 18 seemingly nonsensical characters remaining at the base of the "murder cipher" and the search for a name. Therefore, the response of the "Good Citizen", stating "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", was likely a response to this conundrum. Sgt John Lynch was searching for a name in the 408 cipher, to which the "Good Citizen" replied: "I get the name Jerry" or "his name is XXXXXXX". The October 7th 1969 letter mentioning Beach Street (at the north-eastern edge of Presidio Park), just four days before the Paul Stine murder, is so cryptic in nature, it could be construed as unhelpful and possibly malevolent or mischievous in nature. There is a high degree of probability that the same author was responsible for the "Concerned Citizen" card and "Good Citizen" letter, bearing in mind the August 10th 1969 communication was not in the public domain by October 7th 1969. The two communications both offering answers to the 408 cipher, in addition to the aforementioned similarities. To believe these were authored by separate individuals would require a high degree of mental gymnastics.  

If we have the Zodiac Killer as the author for both of these communications - and consider the message in the 408 cipher and "Concerned Citizen" card declaring "I will not give you my name" and "please forgive the absence of my name" - then the offering of "I get the name Jerry" or "his name is XXXXXXX" as a possible solution to these 18 unsolved characters, would shed doubt on the credibility of, not only the "Good Citizen" author, but the "Concerned Citizen" as being genuinely concerned. If the author of both communications was the same person, we have two conflicting messages. If it's Zodiac, then he is likely playing a game. An individual who helpfully provides a valid key to the 408 cipher on August 10th 1969, while subsequently offering an array of unhelpful cryptic nonsense just two months later, appears to invalidate the original communication as a concerned citizen.

​Does the name "Jerry" or the grouping of seven X's in the "Good Citizen" letter have any bearing on the 18 unexplained characters at the foot of the 408 cipher, or is it just another wild goose chase? One would like to think that the reference to "Jerry" or "XXXXXXX" had some meaning to its author and had some benefit to Sgt John Lynch, rather than complete nonsense that achieves nothing for the sender. The fact that the "Good Citizen" letter (if Zodiac) appears totally unhelpful and arguably bereft of a reasonable aid to solution, could suggest the 18 unsolved characters have no meaning to be found (in complete contradiction to the code key supplied on August 10th 1969 which did aid a solution). Whatever the case, it is with little doubt that the author of these two communications are one and the same - whether that author is Zodiac or not.

On October 22nd 1969, the San Francisco Examiner newspaper published an article by Will Stevens, which laid down a challenge from Professor D.C.B. Marsh of the American Cryptogram Association (ACA) to the Zodiac Killer, attempting to coax him into revealing his name. The newspaper stated "Dr Marsh told the Examiner today: "The killer wouldn't dare, as he claimed in letters to the newspapers, to reveal his name in the cipher to established cryptogram experts. He knows, to quote Edgar Allan Poe, that any cipher created by man can be solved by man. Zodiac has not told the truth in his cipher messages to the Examiner, the Chronicle and the Vallejo Times-Herald. Zodiac has not done this, because to tell the complete truth in relation to his name -in cipher code - would lead to his capture. I invite Zodiac to send The American Cryptogram Association a cipher code - however complicated - which will truly and honestly include his name".

It has been proposed that Dr. Marsh was invoking the name of Edgar Allan Poe to guide the Zodiac Killer down the path of creating a code featured in one of Poe's essays or journals. Just over two weeks later, on November 8th 1969, the Zodiac Killer mailed the recently solved 340 cipher. The scytale method of decryption, that can be used to reveal the message in Zodiac's 340 cipher, was featured in the opening section of Edgar Allan Poe's essay  A Few Words on Secret Writing. The final section of the revealed message in the 340 cipher almost mirrored one of Poe's poems, The final line of the 340 cipher was probably intended to read: "I AM NOT AFRAID BECAUSE I KNOW THAT MY NEW LIFE IS DEATH. LIFE WILL BE AN EASY ONE IN PARADICE". "To One in Paradise" was written by Edgar Allan Poe. This poem was first published as part of the short story titled "The Visionary" (later retitled as "The Assignation"). The poem was also published under the names "To lanthe in Heaven" and "To One Beloved". The title "To One in Paradise" was used in the February 25, 1843 Saturday Musuem. This poem was written after the death of Poe's wife. He writes that she was his life and he lived for her and now he looks forward to the future where they will be together again in death.​ In the Zodiac Killer's 408 cipher, part of the message read: "the best part of it is that when I die I will be reborn in paradise and all the I have killed will become my slaves". The question has always been - what was the inspiration for some of the language he adopted? 

On of the overarching themes in the Zodiac correspondence was his plagiarized acts from The Mikado, a two-part comic opera by Gilbert and Sullivan which opened to the paying public on March 14th 1885, and was hugely successful, running for 672 performances at the Savoy Theatre in London. The Mikado is the most internationally successful Savoy opera and has been especially popular with amateur and school productions. The work has been translated into numerous languages and is one of the most frequently played musical theatre pieces in history. Setting the opera in Japan, an exotic locale far away from Britain, allowed Gilbert to satirise British politics and institutions more freely by disguising them as Japanese.

​The Zodiac would feature three acts from The Mikado in his July 26th 1970 and January 29th 1974 letters - leading many to believe the Zodiac Killer had an avid interest in the theatre, or quite possibly worked there. His Japanese style characters at the foot of the 1974 Exorcist letter could suggest an affinity to Japanese history or culture. 

Taken from Palladiummag.com: "The world of medieval Japan was one of division. The Emperor was, in practice, a distant memory; the shoguns had lost all control over their vassals. Even shrines and temples, once united in strengthening the state through prayer and ritual, now competed for believers and alms. Japan was divided against itself and circumstances forced its inhabitants to form new bonds to survive. Among the new alliances which this age produced were the Ikkō-ikki, a network of autonomous religious collectives that led major uprisings and controlled significant parts of Japanese society for nearly a century. Their final defeat at the hands of Japan’s warrior class set the stage both for a centralized Japanese state and the social hierarchy behind it. Nobunaga, head of the powerful Oda clan, conquered the capital city of Kyoto in 1568. In the years that followed, he made clear his intention to destroy the Honganji sect. The Patriarch Kennyo took him at his word and summoned all Ikkō-ikki from across the country to defend the faith with their lives. Despite graver circumstances than those faced by his predecessor Shonyo, Kennyo did not go as far as implying that those who fought for the Amida Buddha would be guaranteed rebirth in the Pure Land. Nevertheless, he threatened expulsion from the sect for those who failed to respond to the call and he did not crack down on those who raised the Ikkō-ikki’s now-famous banner of war: “Advance and be reborn in Paradise, retreat and fall immediately into Hell.”

​Bearing in mind the numerous plagiaristic references to The Mikado in his letters, along with the plausible connection between the afterlife poem To One in Paradise from Edgar Allan Poe and the wording chosen in the 340 cipher, was the Zodiac Killer influenced by the Japanese Ikkō-ikki’s banner of war “Advance and be reborn in Paradise" and an affinity for the country's culture and belief system, that ultimately manifested in part of his 408 cipher? Not so much a paradise lost, but a paradise found.​

The following is an amalgamation of previous articles: 

​Six months after the Zodiac Killer's Albany, New York letter and code, another letter would arrive at the San Francisco Chronicle on January 30th 1974. Postmarked the day before (January 29th), this letter was a curious blend of The Exorcist movie (1973) and the comedic opera The Mikado (1885), two productions separated by 88 years.

The Zodiac Killer plagiarized The Mikado twice in the July 26th 1970 letter, but this appeared to have some purpose in relation to his hunting activities - that the Zodiac Killer had created a list of potential victims, who he would then kill and ultimately torture in paradise. This seemed at odds with his use of The Mikado in 1974. Any suggestion that the Zodiac Killer was contemplating suicide at this juncture because of his choice of Tit-Willow, appeared to be dashed in the following paragraph when he stated "If I do not see this note in your paper, I will do something nasty, which you know I'm capable of doing". The notion that the Zodiac Killer had reached a watershed moment and was about to ditch the pseudonym he had coveted for so many years, would also be premature, when he mailed the 1978, 1986 and 1987 letters, all containing his infamous introduction of "This is the Zodiac speaking".

​The 1978 and 1987 letters had one thing in common with the 1974 letter, in that they all carried the wording "yours truly" or "yours truley", followed by a colon. This wording is commonly used before a signature, with the colon used to separate two independent clauses when the second explains or illustrates the first. In the 1978 and 1987 letters the Zodiac Killer follows "yours truly" with "guess", whereas, he inserts the plagiarized verse from Tit-Willow where his signature should be placed in the 1974 Exorcist letter. The primary conclusion to draw from this, is the Zodiac Killer was yet again asking us to "guess" his name through the verse of Tit-Willow. 

He may have been bluffing, but giving us his first name in such cryptic fashion could never be realistically used as evidence against him, because any conclusions drawn from this verse through subjective interpretation, would never have any standing in a court of law. There are five things in relation to The Exorcist movie and the Tit-Willow verse that point to one name. There is also another that points backwards to the April 20th 1970 letter, when the Zodiac Killer teased us with his name by stating "My name is", followed by a thirteen character code. The Exorcist book was written by William Blatty in 1971, which told the story of a twelve-year-old girl possessed by a powerful demon, that was later adapted by director William Friedkin in the film version released on December 26th 1973. The Tit-Willow verse from The Mikado was created by William Schwenck Gilbert, which contained multiple examples of "Will" and "Bill" within words such as "Willo" and "Billowy" (Will and Bill being short for William). This verse followed The Exorcist introduction and the promise of a signature by use of "yours truley". If we look at the next paragraph in the Tit-Willow verse from the complete version, it reads "Now I feel just as sure as I'm sure that my name Isn't Willow, titwillow, titwillow". Very reminiscent of the "My name is" letter, but in this instance "My name Isn't". 

Now let us take a look at the final paragraph of the Exorcist letter where he wrote "If I do not see this note in your paper, I will do something nasty, which you know I'm capable of doing". This mirrors his very first communications on July 31st 1969 when he wrote "I want you to print this cipher on your frunt page by Fry Afternoon Aug 1-69, If you do not do this I will go on a kill ram page Fry night that will last the whole week end. I will cruse around and pick of all stray people or coupples that are alone then move on to kill some more untill I have killed over a dozen people". On July 31st 1969 and January 29th 1974, he concluded both correspondences with the threat "to kill" more people if his letters were not published in the newspapers. In his decoded 408 cipher, he wrote "To kill something gives me the most thrilling experence". To the best of my knowledge, this is the only time the Zodiac Killer used the word "something" prior to January 29th 1974 - and used it in reference "to kill something". So, when we look at the final paragraph of the Exorcist letter where he wrote the words "I will do something nasty", it is apparent that "to kill something" was his likely threat. The Zodiac Killer then finished the letter with another puzzle (likely decoded by Kevin Robert Brooks). 

When determining whether the "concerned citizen" card mailed to Sergeant John Lynch on August 10th 1969 was written by a helpful member of the public or the Zodiac Killer, we need look no further than the "good citizen" letter mailed on October 7th 1969. Despite the fact the "concerned citizen" card was not in the public domain in 1969, the "good citizen" author would also adopt the word "citizen" in their signature, address the communication to Sergeant John Lynch once again, and refer to the July 31st 1969 cryptogram by mentioning "code letters", just as the "concerned citizen" author was addressing the "code letters" by supplying us with a key to the 408 cryptogram. These are compelling reasons to believe that both communications were composed by the same author. The question being; is the wording in the "good citizen" letter that of a helpful citizen or a mischievous individual playing games with the police. The "good citizen" letter read "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".  

The "good citizen" letter was postmarked October 7th 1969 and mentioned 56 Beach Street, which is the old block numbering from the original planning maps, which comes out as 1654/1656 on the street numbering. The address at 1654/56 Beach St, San Francisco, California is a condominium home that measures 2,141 sq ft, and was built in 1938. Irrespective of the exact numbering, Beach Street is just 240 meters from the Presidio of San Francisco, where eyewitnesses saw a white male, about 40 years of age, weighing 170lbs, sporting a blond crewcut and wearing glasses, running into Julius Kahn playground shortly after the murder of Paul Stine on October 11th 1969. Of all the places in northern California or the Bay Area the author could select, the composer of the "good citizen" letter was not only referring to Zodiac's code letters, but managed to choose the location of Beach Street, bordering the Presidio in which the Zodiac Killer possibly escaped into just four days later. Possibly coincidence, but noteworthy nonetheless. The "good citizen" author may have been referring to Beach Street in San Francisco just a matter of days before the Zodiac Killer first struck in the big city, before mailing a letter on October 13th 1969, again detailing a destination in the form of a street name - this time "Washington St and Maple St".   

This letter, likely referring to San Francisco, may hold some significance when we consider the statement of Jim Dunbar on October 22nd 1969, when somebody pretending to be the Zodiac Killer rang into the KGO-TV Jim Dunbar Show. He asked the caller "Did you try to call us one other time, about two or three weeks ago. Did you attempt to call this program one other time when Mr. Belli was with us?" It can be understood why the hoaxer, Eric Weill, would ring into the Jim Dunbar Show, because he got wind that the Jim Dunbar Show was possibly entertaining a call from the Zodiac Killer that morning. Therefore, it isn't unreasonable to conclude he used opportunism to hijack the limelight. But why would Eric Weill claim to be the Zodiac Killer and ring into the Jim Dunbar Show "two or three weeks" earlier, when the Zodiac Killer had never comitted an attack in San Francisco at this juncture?

The Zodiac Killer wanting a TV audience in San Francisco on October 22nd 1969 after his murder of Paul Stine in San Francisco eleven days earlier, can be argued. It is also possible that the Zodiac Killer may have rang into the Jim Dunbar Show "two or three weeks" earlier (between October 1st and October 8th), requesting a slot on the show to announce his intentions of bringing terror to the heart of San Francisco. A phone call placed to the Jim Dunbar Show in San Francisco on October 8th 1969 would coincide with the "good citizen" letter on October 7th 1969, also possibly involving a location in San Francisco - and both would predate the murder of Paul Stine in San Francisco by just a matter of days. A murder, in which the Zodiac Killer was spotted entering the Presidio grounds, which Beach Street borders. If we are to determine whether the "concerned citizen" card on August 10th 1969 was mailed by the Zodiac Killer, we have to factor in the letter on October 7th 1969 and the phone call to the Jim Dunbar Show around the same time - and the significance they may, or may not hold.  

On July 31st 1969, three parts of one whole cipher were mailed to the Vallejo Times-Herald, San Francisco Examiner and San Francisco Chronicle by the Zodiac Killer, with the latter promising to give us his identity. But what was the inspiration behind the Zodiac Killer mailing letters to three newspapers with part of his manifesto encoded in ciphertext? In his San Francisco communications he spelled his offerings as a "cipher", yet in his offering to the Vallejo Times-Herald he used the variant spelling of "cypher", with the addition of letter "i" to form "cyipher". The Chronicle and Examiner jointly released a Sunday newspaper with a dedicated weekly section called The Puzzle Page, that contained a cryptogram called the Chronicle Cypher. The July 27th 1969 edition supplied us with a 78 character cryptogram, split by message and name, with the answer supplied on page 27. The newspapers puzzle and answer section also contained two variant spellings of the word cipher.

On August 10th 1969, a "concerned citizen" addressed a communication to Sergeant John Lynch of the Vallejo Police Department and supplied the code key to the 408 cipher, stating "Dear Sergeant Lynch. I hope the enclosed "key" will prove to be beneficial to you in connection with the cipher letter writer. Working puzzles criptograms and word puzzles is one of my pleasures. Please forgive the absence of my signature or name as I do not wish to have my name in the papers and it could be mentiond by a slip of the tongue. With best wishes. concerned citizen". The author of this communication (who many believe to be the Zodiac Killer) also gave us a variant spelling (albeit incorrect) of "cryptogram", by using "criptogram". The author also expressed an interest in "word puzzles" on August 10th 1969. So was the Zodiac Killer's inspiration for the July 31st 1969 letters derived from the Sunday newspaper puzzle page?  

Thanks to Cragle for the information used in this article. 

The above message of 408 characters is what I believe was originally crafted by the Zodiac Killer before he accidentally skipped a line during encryption. There is every chance the Zodiac Killer wrote the plaintext of his message in a continuous 17 by 24 grid, from which he would create three ciphertext messages of 17 by 8 to the Vallejo Times-Herald, San Francisco Examiner and San Francisco Chronicle. He finished encrypting the plaintext message of "TH" to the Examiner, knowing that he had to begin the Chronicle message by encrypting the "E" to complete the word "THE". Unfortunately, when he returned to his plaintext grid of 17 by 24, he accidentally used the "E" from the 18th line instead of the 17th line, thereby creating an encrypted message that read "The best part of it is that when I die I will be reborn in paradice and all the I have killed will become my slaves". 

At some point he must have realized this, so effectively used some type of filler at the bottom of the cipher. Had the original message finished with "stop my collecting of slaves for the afterlife", rather than grammatically inferior "stop my collecting of slaves for my afterlife", the original message would have been the full 408 characters (shown above). It may be the case that once he realized his mistake of missing a line - and knew he now had only seven rows comprising the ciphertext to the Chronicle - he lost his train of thought. The accuracy of the remainder of the message regarding "THE" or "MY" was now an irrelevance.

The Zodiac Killer only used the word "LONE" in his address to the San Francisco Chronicle when requesting they print the cipher, so it's fitting that this word should have begun the ciphertext he mailed to them. The use of "STRAY PEOPLE" featured in the communication to the Vallejo Times-Herald, thereby completing the phrase "all the lone or stray people" that ran through rows 16, 17 and 18. The missing line (added in the diagram above left) only uses words from his July 31st 1969 letters.

Attempting to find an answer to the "18 unsolved characters" relies on the assumption that his original encryption was correct, which clearly it wasn't. The Zodiac Killer certainly misspelled words in his communications, but rarely, if ever, did he omit words entirely. If the Zodiac Killer had written his original plaintext grid of 17 by 24 into three separate and distinct sections, it's highly unlikely this mistake would ever have occurred (so it's likely he didn't). When reading text in any form, it's easy to accidentally skip a line or read a line twice. The former may have been the case with respect to the Zodiac Killer. 

Thanks to Dave Oranchak for first floating the idea of a missing line, which I now believe is the likeliest answer.

Inspired by an idea floated by Dave Oranchak of Zodiac Killer Ciphers and the third instalment of his Let's Crack Zodiac series, we will take another look at the 408 cipher and the notion of a killer who simply skipped a line accidentally when transferring his 17 by 24 plaintext grid into three separate 17 by 8 ciphertext mailings. It was an easy error to make, bearing in mind that the letter E may have began three consecutive rows on the original plaintext 408 (rows 17, 18 and 19). The Zodiac Killer may have inadvertently missed out ELONEORSTRAYPEOPL while transferring from his 17 by 24 plaintext grid into the ciphertext mailed to the San Francisco Chronicle newspaper. He accidentally enciphered the next row, which also began with the letter E, converting EIHAVEKILLEDWILLB into ciphertext (which unfortunately now began the enciphered message to the Chronicle). This created the appearance of a missing word (such as people) in "the best part of it is that when I die I will be reborn in paradise and all the (people) I have killed will become my slaves".  

The reason for believing that ELONEORSTRAYPEOPL are the missing 17 letters of plaintext, is based on his threats to the three newspapers, who he threatened with devastating consequences if they failed to publish his cipher by the afternoon of Friday, August 1st. The Zodiac Killer, when finishing his encryption, would now realise his mistake, but for whatever reason decided not to go back and correct the error. His original intention may very well have been to leave just one apparently meaningless plaintext letter E at the end of the 408 cipher (effectively creating a 407 character cipher). That is, until we run the decoding process for a second time.

Dave Oranchak showed us how the Zodiac Killer enciphered his letter E's as he traveled through the 408 cipher, by cycling through Z9W+ONE (O with dot). which all represented the letter E and created a repeating sequence (despite breaking down towards the end). This is shown at 32:47 on his Let's Crack Zodiac episode. If we apply a second decoding to the letter E remaining at the end of the 408 cipher, the letter E would now be replaced by the letter Z, which begins this repeating sequence. The 408 cipher would now be complete with a message and signature (or identity). The Zodiac Killer would be signing off his cipher with the letter Z, partially and fully evident in the April 30th 1967 Bates letters and October 27th 1970 Halloween card. Whether the letter E required a second decoding is unproven, but it's a tantalizing prospect regarding a killer who initially boasted "in this cipher is my idenity" - and a missing line that makes this all possible.

Let's Crack Zodiac (Part One)      Let's Crack Zodiac (Part Two)

The Zodiac Killer murdered David Faraday and Betty Lou Jensen in Benicia on December 20th 1968, before moving into Vallejo on July 4th 1969 with the attack at Blue Rock Springs on Darlene Ferrin and Michael Mageau. He had successfully committed two late night attacks on two young couples - and by the time he had mailed his July 31st 1969 letters and cryptograms to the San Francisco Chronicle, San Francisco Examiner and Vallejo Times-Herald newspapers - the police were no nearer to catching him. By all accounts, this seemed a rather 'successful' opening to his serial killer career, evolving from the murderer of three into the ominous Zodiac Killer by August 4th 1969. This being the case, why did the Zodiac Killer rip up this template of murder and embark on a whole new path on September 27th 1969, leaving many observers to this day questioning the Lake Berryessa stabbings as a Zodiac crime? Rather than constantly examining the modus operandi between the three crimes and questioning their incompatibility with one another, it may be more productive to discover the reasons why the Zodiac Killer dropped an approach that had worked on December 20th 1968 and July 4th 1969, to now adopt a brazen attack with a knife in daylight hours. Something happened externally or internally to provoke this switch in attack style.

The Zodiac Killer by August 4th 1969 had murdered three people, severely injured one, mailed three cryptograms and written four letters. From the outset he placed importance on receiving front page coverage. On July 31st 1969, his trinity of communications demanded that he received front page coverage, stating "I want you to print this cipher on the front page of your paper. In this cipher is my idenity. If you do not print this cipher by the afternoon of Fry.1st of Aug 69, I will go on a kill ram-Page Fry. night. I will cruse around all weekend killing lone people in the night then move on to kill again, until I end up with a dozen people over the weekend". Imagine his horror and dismay, 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 in his eyes), literally spat in his face, by placing their portion of the cryptogram on a lowly page nine. This wouldn't go unnoticed by the killer of three on August 4th 1969, who hastily composed a fourth letter with an imposing pseudonym and uttered his displeasure by stating "I was not happy to see that I did not get front page coverage". We have come to understand the Zodiac Killer as a narcissistic braggart, whose primary objective wasn't the murders, but the publicity they generated. This publicity, to him, meant front page coverage in the major newspapers of the day - not page four and certainly not page nine. 

Just when the Zodiac Killer didn't think it could get any worse, the San Francisco Chronicle ran a front page article on August 6th 1969, entitled The Frenzy of San Jose Girls' Slayer, detailing the brutal stabbing murders of two young teenagers in San Jose on August 3rd 1969. This article arrived just two days after his dismay at not receiving front page coverage. The San Francisco Chronicle article read as follows:

The two young girls, found dead Sunday on a sun-parched San Jose hillside, appear to have been victims of a sexual psychopath, whose blood frenzy led him to "overkill."  Dr. John E. Hauser, Santa Clara county's chief medical examiner and coroner, said yesterday that the girls, Deborah Gay Furlong, 14, and Kathy Snoozy, 15, died in a "frenzied flurry of knife-wounds" inflicted so swiftly that neither gave any evidence of having struggled against the attack. Dr. Hauser, so shaken by the brutality of the crime he could scarcely find words, said the Snoozy youngster had 150 wounds on her back, 50 on the front and a "storm" of punctures on her neck. Deborah's body had about 100 wounds on her back and upper front and a dozen on her neck.

PUZZLE: Dr. Hauser said he was "puzzled" by many aspects of the brutal slaying. He said neither girl had been sexually molested; neither had suffered any wounds below her waist, neither gave evidence of having struggled to escape. Only the Snoozy girl, he said, had one small mark on her hand, suggesting she may have tried vainly to deflect the plunging knife. The coroner said both girls must have died very quickly and he is investigating the possibility they may have been drugged before the stabbing began. Blood and skin samples as well as stomach contents have been sent for further examination to area laboratories, he said. The results should be known in a few days. It is Dr. Hauser's opinion that the multiple puncture wounds were inflicted by one or two small knives, the largest wound the size of a pocket knife with a half-inch blade. "I've never seen a case with this many stab wounds," Dr. Hauser said. "You know, I've been in this profession a long time and sometimes I think I'm rather callous, but when I saw these girls, believe me it was terrifying. "The Nazi sex mutilations during World War II were nothing compared to what was done to these young girls.

INVESTIGATION: So far, according to Chief of San Jose Detectives Barton Collins, his investigators have uncovered no solid clues to the slaying. He said police and sheriff's deputies are looking for a "light colored van—a Volkswagen, a Dodge, a Chevrolet or a Ford" in which the girls may have been killed and then rolled, carried or dragged down the hillside to a grove of snarled, dusty oaks where their bodies were found. Both he and the coroner emphasized that at the scene there was almost no blood, suggesting they had been slain elsewhere. Collins said he and his men have talked to at least 200 people so far, searching for some information that might draw them closer to the killer. Asked if he were looking for a "mad man," Collins, pale and exhausted, snapped: "I'm looking for a killer and it doesn't matter whether he was under drugs or what." Collins did not mention this, but the Chronicle learned that wedged in between the two bodies of the dead girls police found a "new," but empty beer can. There was speculation the killer may have rolled or carried one girl down, then finished off a can of beer, and then disposed of the second body without noticing the can. The scene, not more than six blocks from where the two girls lived with their families in a neat, prosperous subdivision in San Jose's Almaden area, was utterly desolate yesterday. A few small boys on bicycles paused to look up at the tanned knoll, swathed with wide paths used for scrambles by neighborhood motorcyclists, and scurried off. Normally scores of children play in that area, because, in the words of Deborah's father, Glen Furlong, "It's the only open area close by where kids can go to." Housewives living in the immediate area, across the street and around the corner, conceded they were suddenly "very frightened." One mother said that since the murder she had seen some children poking around the scene, and added, "We were shocked. "Maybe their parents don't care. But I wouldn't let mine go up there . . . "

PUBLICITY: Although very close to tears, Furlong said yesterday that he was allowing interviews in the hope that more and more publicity "would trigger something in someone's mind and we can solve this crime." The 40-year old father works at the big International Business Machines plant only about a mile away from the family home. He is a senior associate engineer in the logic design section of IBM and he tried to bring objectivity to the disaster that has befallen his family. "The individual or individuals who did this either had to be deranged or high on dope or something of that nature," he said. "They didn't know what they were doing. It was such a senseless killing." He said his neighborhood has never had any problems, although mahy complain about the noise made by the weekend cyclists. He noted parenthetically that the riders are not of the Hell's Angel variety, but use lighter motorcycles. He said his neighbors were "very sympathetic," but complained he found some of his phone calls "very disconcerting."

CALLERS: "On several occasions people have called and as soon as we answer, they hang up," he said in bewilderment. Furlong tried to control his emotions as he spoke of his eldest daughter — one of his four children. "She was only a freshman in high school," he said, "and this was the first year we allowed her to date. We talked to her about it, and I sort of teased her. She went out with a boy friend a few times — a very nice boy who came over yesterday morning to extend his condolences — but most of her social activities were confined to her school. She was never any trouble." School mates and neighborhood friends of Deborah said the girl, very slim and looking more like a 10-year-old than a 14-year-old, was "just an ordinary nice girl who baby set and had a boy friend and talked about becoming an airline stewardess."

CHILDREN: The other Furlong children are Glen, 16; Floyd, 12, and Pamela, 11. Furlong said he did not know and had not yet talked to Kathy's parents, Mr. and Mrs. Wilfred Snoozy. Both Snoozy, a carpet layer, and Mrs. Snoozy reportedly are in a state of collapse. Her funeral has been scheduled Friday at 11 a.m. at the Place Funeral Home in Los Gatos. Burial will be at Oak Wood Cemetery in Santa Cruz. Funeral services for Kathy will be held tomorrow (Thursday) at 2 p.m. at the Oak Hill Memorial Park Mortuary in San Jose. Burial will be at Oak Hill Memorial Park.  

The Zodiac Killer, avidly scanning the newspapers for progress on his cryptograms and latest letter, must have been bitterly disappointed that these murders committed in San Jose featured front and center of the San Francisco Chronicle, while his three murders, allied to his cryptic ciphers, were relegated to page four and nine of the two San Francisco newspapers. He needed to switch his approach to murder and hit San Francisco hard.

The phrases of "The Nazi sex mutilations during World War II were nothing compared to what was done to these young girls", the title of "The Frenzy of San Jose Girls' Slayer" and "Dr. Hauser, so shaken by the brutality of the crime he could scarcely find words", must have resonated with the Bay Area murderer. He knew that to generate the front page coverage he so badly craved, he needed to switch from gun to knife in a savage close-quarter attack. However, he needed to elevate the fear by dressing up in a costume with his moniker emblazoned on his chest, akin to the fear the Nazi swastika instilled in its victims. He would also ramp up the terror by using a bayonet-style knife, rather than the pocket knife used in the Snoozy and Furlong murders. This article alone was the driver behind the Lake Berryessa stabbings, and effectively sealed Bryan Hartnell and Cecelia Shepard's fate, seven weeks in advance of the crime. The Zodiac Killer, dressed in ordinary clothes, gazed into the mirror and effectively saw the costumed Lake Berryessa murderer staring back at him. His fantasy was taking shape.         

Three girls from Pacific Union College may have been the initial target of the Zodiac Killer as he scoured the hillsides of Lake Berryessa, but circumstances unknown would ultimately change what transpired. Two hours later, an ominous figure stepped out from behind a tree at Twin Oak Ridge and bore down on Bryan Hartnell and Cecelia Shepard. The Zodiac Killer's fantasy, driven by the August 6th 1969 San Francisco Chronicle article, had emerged into reality. The Snoozy and Furlong murders on August 3rd 1969 were about to be replicated in the mind of a killer. The costume specifically designed and crafted with care, by a man who fed into his own narcissism and who was now on the verge of securing the recognition he felt he so richly deserved. Whether the couple survived the upcoming attack and reported what they saw was incidental - the Zodiac Killer had now satiated his desire to become the embodiment of fear, he viewed as being denied from him and his accomplishments after the trinity of cryptic communications on July 31st 1969.

After the attack on the couple, he made his way up the hillside to the Volkswagen Karmann Ghia of Bryan Hartnell and defiantly listed his accomplishments on the door of the vehicle, but specifically added the words "by knife" at the foot of the message. He was effectively making a statement to the San Francisco Chronicle (and to a lesser extent, The Examiner), "do I get front page coverage now". The Snoozy and Furlong murders, in his mind, had overshadowed his accomplishments at Lake Herman Road and Blue Rock Springs, despite the cryptic offerings he had so painstakingly crafted. So he crafted a costume instead and attempted to ramp the fear factor to a new level. The fact that Bryan Hartnell survived the Lake Berryessa attack, inadvertently played right into his hands. The evil, fear-inducing costume he had carefully crafted and labored over, was now the focus and feeding frenzy of a media gripped by this new revelation. The second coming of Zodiac was now complete - and his requirement to converse with the newspapers strangely deflated, because Bryan Hartnell had successfully recounted the details of Lake Berryessa with astonishing clarity and vividness. The Zodiac Killer had now been reborn and resurrected from gun-toting lunatic into the embodiment of evil. This crime also had one added benefit with respect to the identity of the killer of Snoozy and Furlong - and I doubt this possibility escaped the attention of the Zodiac Killer when he arrived at Lake Berryessa on September 27th 1969.    

In an article entitled Another Grim Message by Paul Avery, a link between the Lake Berryessa stabbings and the murder of the two San Jose teenagers was pondered by both investigators and newspapers alike. The Zodiac Killer had deliberately emphasized "by knife" on the car door at Twin Oak Ridge, and included "Aug" in his victim months on the Dripping Pen card for this very reason. When he mailed the November 8th 1969 Dripping Pen card, he requested "I though you would nead a good laugh before you hear the bad news. You won't get the news for a while yet. PS could you print this new cipher in your frunt page? I get aufully lonely when I am ignored, so lonely I could do my Thing !!!!!!  Des July Aug Sept Oct = 7". The Zodiac Killer didn't need to demand front page coverage anymore, he knew he would get it. By committing the Lake Berryessa stabbings and including "Aug" in his chronology of months, he had effectively planted the seed in investigators minds that he could have been responsible for the Snoozy and Furlong murders in August. He had essentially bought himself front page coverage by piggybacking off a crime he already knew had achieved this status on August 6th 1969.
Just like the threat to pick off schoolchildren and blow up a school bus, the savagery of these two close-quarter attacks demanded he be taken seriously. Whatever we say about the Zodiac Killer, his marketing skills were second to none. He knew how to turn page four and page nine into page one, placing Another Grim Message proudly on the news stands of San Francisco.    

The importance of the San Francisco Chronicle article from August 6th 1969 cannot be underestimated with respect to Lake Berryessa and future Zodiac communications. Who would remember the burial location of one of the victims from San Jose, if not the killer who was so influenced by this very article? Who then shifted from impersonal double shootings at Lake Herman Road and Blue Rock Springs, to intimate stabbings at Lake Berryessa. Only somebody invested in murder during the time  period this article was released, would have reason to remember where the two San Jose teenagers were laid to rest. Under CHILDREN in the August 6th 1969 Chronicle article, it stated "The other Furlong children are Glen, 16; Floyd, 12, and Pamela, 11. Furlong said he did not know and had not yet talked to Kathy's parents, Mr. and Mrs. Wilfred Snoozy. Both Snoozy, a carpet layer, and Mrs. Snoozy reportedly are in a state of collapse. Her funeral has been scheduled Friday at 11 a.m. at the Place Funeral Home in Los Gatos. Burial will be at Oak Wood Cemetery in Santa Cruz. Funeral services for Kathy will be held tomorrow (Thursday) at 2 p.m. at the Oak Hill Memorial Park Mortuary in San Jose. Burial will be at Oak Hill Memorial Park".

The Oak Hill Memorial Park & Cemetery in San Jose lies in the Monticello neighborhood, just nine miles east of the Villa Montalvo woods, where Kathy Bilek was brutally stabbed on April 11th 1971 - and who the Zodiac Killer referenced in his July 13th 1971 communication, stating "Near Monticello Shought Victims 21 ...... In The Woods Dies April". There are a multitude of places in San Jose the author of this card could have chosen, but he chose Monticello. The exact place Kathie Snoozy was buried - and the teenager whose murder he insinuated his involvement in on November 8th 1969. When Karl Francis Werner was attributed with the murders of Debra Furlong, Kathie Snoozy and Kathy Bilek, the Zodiac Killer had the option to recuse himself of all involvement in the two San Jose murders. But that wasn't his style. The attack at Lake Berryessa, the Dripping Pen card, and a whole host of communications involving San Jose had locked him into a lie he was unwilling to relinquish. He would effectively try to reclaim the Snoozy and Furlong murders, by also claiming the Kathy Bilek murder in Saratoga via the Monticello card, as well as calling Werner a phony in another Zodiac communication mailed in May 1971 (shown below). The Zodiac Killer had simply invested too much time and effort into this elaborate facade, that was encapsulated by his theatrical performance at Lake Berryessa. Two years he had lived in a house of illusion - and Karl Francis Werner was not going to tear it down. 

Recently I have examined a connection between the 1969 and 1987 Vallejo Times-Herald envelopes not only through handwriting, but through design. We know of only three communications to the Vallejo Times-Herald, mailed on July 31st 1969, October 28th 1987 and September 25th 1990. There is a strong possibility that the Bay Area murderer mailed all three. I am sure he was a killer who meticulously kept all the newspaper cuttings written about him over the years and drew inspiration from them when he mailed his latter communications, dropping in subtle clues beyond the capability of the casual hoaxer. 

If we take a look at the three July 31st 1969 letters, you will notice that the communication addressed to the San Francisco Chronicle contained the word "cipher" spelled correctly five times. To the San Francisco Examiner the word "cipher" was spelled correctly three times. In the Vallejo Times-Herald he spelled the word "cipher" correctly once, while spelling it incorrectly on the only other occasion, depositing the letter "Y" into the word (cyipher). The author of the postcard mailed on September 25th 1990 from Oakland, addressed the card as the Celebrity Cypher to the Vallejo Times Herold Vallejo CA. The 1969, 1987 and 1990 communications all used the full address of the newspaper, despite the publicly known July 31st 1969 letters to the Chronicle and Examiner only using the title of Vallejo Times.

But more crucially, both the communications on July 31st 1969 and September 25th 1990 addressed the Vallejo Times-Herald as "Herold", switching the "A" for an "O". I have contacted the editor of the Vallejo Times-Herald for a clearer image of the October 28th 1987 envelope and he promised to have a look in the files. Not only would we be able to view the handwriting in greater clarity, but we would find out if he addressed the envelope "Herold" for a third time. If he did, then the Bay Area murderer would have mailed only three communication to the Vallejo Times-Herald (that we know of), and all would have contained the misspelling of "Herald" to "Herold".

Below is an FBI file from November 8th 1973 carrying the name of Leslie B. Lundblad, analyzing some handwriting in respect to the Vallejo Times-Herald envelope, the Debut of Zodiac letter and the Little List letter. It is accompanied by two excerpts from the Zodiac Killer FBI files (Part One). All three FBI documents feature the address used on the July 31st 1969 Vallejo Times-Herald envelope. All three show that it was addressed to the Vallejo Times Herold, just like the 1990 Celebrity Cypher. What is the betting on the October 28th 1987 envelope containing the word "Herold" as well? Could a casual copycat just keep getting so many things correct, despite having no access to any of the preceding Zodiac envelopes - or is it more likely that the Zodiac Killer was more nuanced than we give him credit for.

The Zodiac Killer made an error when transitioning from cipher two (mailed to the San Francisco Examiner), to cipher three (mailed to the San Francisco Chronicle) in the 408 cipher. Since the Zodiac Killer used the word "people" six times in his July 31st 1969 communications, it's probably a safe bet that the missing word in "The best part of it is that when I die I will be reborn in paradice and all the (?) I have killed will become my slaves", is people. Therefore, it is highly unlikely that the Zodiac Killer ever intended to leave 18 characters at the foot of the 408 cipher - rather 12 characters.

Dave Oranchak, author of the hugely successful website Zodiac Killer Ciphers, managed to stick a giant monkey wrench in this conclusion with an excellent idea, by suggesting that the Zodiac Killer may have inadvertently missed out a whole line from his cipher. Although this may on first consideration seem less likely, it must be noted that row 17 and row 18 would both begin with the letter "E" in the new presentation. Dave Oranchak  came up with an idea for the missing line (shown below left), to which I added a further suggestion (shown below right). The idea behind my suggestion, was utilizing the words chosen by the Zodiac Killer when he threatened to kill more "people" in his July 31st 1969 letters.

#1. In his communication to the Vallejo Times-Herald, the Zodiac Killer wrote "I will cruse around and pick of all stray people or coupples that are alone then move on to kill some more untill I have killed over a dozen people".

#2. In his communication to the San Francisco Examiner, the Zodiac Killer wrote "If you do not print this cipher, I will go on a kill rampage Fry night. This will last the whole weekend, I will cruse around killing people who are alone at night untill Sun Night or un till I kill a dozen people".

#3. In his communication to the San Francisco Chronicle, the Zodiac Killer wrote "I will go on a kill ram-Page Fry. night. I will cruse around all weekend killing lone people in the night then move on to kill again, until I end up with a dozen people over the weekend".  

The reason to suspect the missing section of 17 letters/characters would have been "lone or stray people", is because the Zodiac Killer used these exact words in the Vallejo Times-Herald and San Francisco Chronicle above. This suggestion by Dave Oranchak, of the Zodiac Killer accidentally omitting a whole line from his plaintext draft to ciphertext encryption, would have the added benefit of filling 407 of the 408 characters in the cipher.

It is easy to see how the Zodiac Killer may have made this mistake, when his original draft had the letter "E" beginning both row 17 and row 18. A cipher created by the Zodiac Killer using 407 characters out of 408 spaces (arranged 17 X 24) seems far more acceptable. This would have left little room for his identity on the final row, if indeed one was ever meant to be reserved for the final line of the cipher. The only possibility would have been "Z" - now that takes me back a few years. 

Thanks to Dave Oranchak.

When the Zodiac Killer mailed his July 31st 1969 letters to the San Francisco Chronicle, San Francisco Examiner and Vallejo Times-Herald, he informed each newspaper to the fact he had mailed letters to the other two. He addressed the San Francisco Chronicle as S.F. Chronicle on its envelope and in the letters to the other newspapers, the San Francisco Examiner as S.F. Examiner on its envelope and in the letters to the other newspapers, but addressed the Vallejo Times-Herald as Vallejo Times Herald on its envelope and Vallejo Times to the other newspapers. The 1969 Vallejo Times-Herald envelope had not been made visible to the public at the time the disputed October 28th 1987 Halloween letter arrived at the Vallejo Times-Herald (as far as I can ascertain). The three July 31st 1969 envelopes even failed to make the San Francisco Police Department DNA report in the late 1990s.

An article from ABC News in 2003: "The lab has found a partial DNA "fingerprint" on one of the envelopes, but not enough for definitive matching. However, a Primetime investigation prompted the discovery of three envelopes that offer new hope. The envelopes (July 31st 1969) were thought to have been lost, but an anonymous Primetime source — a long-retired investigator — found them, in mint condition, during a search of his personal files and turned them over to the San Francisco police".

Experts very quickly determined the 1987 letter was mailed by a hoaxer. "The fake letter sent to the Vallejo Times-Herald in midweek was a simulation of a hoax letter written in 1978", police Capt. Roy Conway said Thursday. "The determination was made by experts in the state Department of Justice", he said. In Sacramento, spokeswoman Melinda Stehr of the attorney general's office said handwriting experts confirmed the letter was a simulation of a letter sent to the San Francisco Chronicle a decade ago, which was also considered to be a hoax."Someone saw the letter and was using it as a copy."  Stehr said. "It's a fake. It's a hoax". When they made this determination, they clearly didn't have the July 31st 1969 Vallejo Times-Herald envelope at their disposal, so they could compare it to the October 28th 1987 envelope. If they had, they may very well have come to a different conclusion. The Zodiac Killer wrote 'Vallejo Times' in his letters when he addressed the Chronicle and Examiner on July 31st 1969 (which were made public), but his envelope to the Vallejo newspaper contained the full name of 'Vallejo Times Herald'. An envelope not made public prior to October 28th 1987. Yet the recent 1987 envelope contained the full title of 'Vallejo Times Herald', just like the unpublished 1969 Vallejo envelope.

If you compare the now available July 31st 1969 Vallejo Times-Herald envelope, with the October 28th 1987 Vallejo Times-Herald envelope, the similarity is noticeable. How could a hoaxer mimic the 1969 Vallejo envelope so closely if he had never laid eyes on it. The same words and amount of words (and abbreviations) are used in both, with no commas or full stops in either address. The dominant alphabetical V is present on both, with a distinct right leaning slant extending over the "a" of Vallejo. Up to October 28th 1987, these were the only two communications ever mailed to the Vallejo Times-Herald from either Zodiac, or a supposed copycat of Zodiac. If the July 31st 1969 Vallejo Times-Herald envelope was never made public prior to October 28th 1987, I suggest that this recent Halloween offering should be declared genuine Zodiac Killer correspondence. This is the best image available of the 1987 envelope. There are two March 29th 1985 issue date 22c stamps of Flag Over Capitol on the 1987 envelope. The May 6th 1986 'Zodiac' envelope contains one smaller Flag Over Capitol stamp.          

This article is what I would describe as an investigative piece written with impartiality to the best of my knowledge. We know that the July 31st 1969 letters were the Zodiac Killer because of their content, so if the October 28th 1987 envelope can unequivocally be tied to one of these letters through the handwriting style and composition of each envelope, we can say without doubt the Bay Area murderer was still alive in 1987. However, if any reader of this article can find the July 31st 1969 Vallejo Times-Herald envelope published prior to October 28th 1987, for the latest Halloween letter author to mimic, I will delete this article immediately.  

Many Zodiac enthusiasts have pondered from where did the Zodiac Killer acquire his pseudonym, or when he decided upon the name Zodiac. The Bay Area murderer arrived at Lake Herman Road on December 20th 1968, where he callously executed David Faraday and Betty Lou Jensen with six shots to the head and body. Just over seven months later, on July 31st 1969, he mailed three pieces of correspondence to the San Francisco Chronicle, San Francisco Examiner and Vallejo Times-Herald, but failed to introduce himself as Zodiac despite having over half a year to formulate a pseudonym. He only introduced himself as the "killer" and "murderer".

Three letters, detailing his crimes and awash with cryptograms, announcing his arrival to the newspapers, seemed like the perfect opportunity to announce those infamous words of "This is the Zodiac speaking" - yet nothing. His next communication was only sent in response to Vallejo Police Chief Jack E. Stiltz, who doubted the letter writer and killer were the same person and "urged the writer yesterday to send more letters with more facts to prove his connection with the crimes". The Bay Area murderer immediately replied on August 4th 1969, stating "This is the Zodiac speaking. In answer to your asking for more details about the good times I have had in Vallejo, I shall be very happy to supply even more material". It can be seen that this letter would never have been sent, had Vallejo Police Chief Jack E. Stiltz not urged the killer to do so. If the letter had not been sent, then our killer would not have presented himself as Zodiac on August 4th 1969. In fact, he may not have adopted the pseudonym at all.

In absence of this letter, the next letter to contain his pseudonym was mailed two days after the Paul Stine murder on October 13th 1969. So, it's entirely plausible that the muderer of five could have begun and ended his attacks in the Bay Area as a nameless killer. The Vallejo News Chronicle published one-third of his 408 Cipher on August 1st 1969, the San Francisco Chronicle did the same on August 2nd 1969, with the San Francisco Examiner waiting until August 3rd 1969 and publishing all three parts, but on a lowly page nine. All three carried the message from Vallejo Police Chief Jack E. Stiltz, yet despite the Examiner publishing their part of the cipher the latest and relegating it further from the front page than the other publications, in defiance of his demands for front page coverage by Friday afternoon, it was the Examiner he chose to introduce his pseudonym to. In other words, they complied the least, but the killer chose to "supply more details" to them rather than a Vallejo publication and to the home city of Vallejo Police Chief Jack E. Stiltz, who he was supposedly addressing.

There is a real possibility that the murderer of three chose the San Francisco Examiner because they were the only publication to give the murderer a pseudonym, which may have ultimately triggered the following communication a day later. The Examiner wrote "The police telephone system was clogged by anxious callers asking if the "cipher killer" had been caught". The murderer seemingly didn't appreciate the pseudonym given to him and a day later, on August 4th 1969, he introduced himself to the Bay Area with "This is the Zodiac speaking". But why this phrase? The Examiner article noted that "the police telephone system was clogged by anxious callers asking if the "cipher killer" had been caught", so what better way to announce yourself as you might do over the telephone. This wasn't an anxious caller, this was the Zodiac speaking.  

Without this San Francisco Examiner article and resultant Debut of Zodiac Letter on August 4th - announcing yourself as the "Zodiac" on October 13th 1969 after the end of a ten month series of murders, certainly wouldn't have had the same impact. Without the publication of "cipher killer", the pseudonym of the Zodiac Killer would in all probability never have existed.

The counter-argument to the above, is the killer had ample time to give himself a pseudonym from December 20th 1968 to July 31st 1969, and only began the trinity of letters with "murderer" and "killer" because he had reserved the pseudonym "Zodiac" for the 18 characters at the foot of the Chronicle cipher. This was the portion he claimed held his "identity". A hidden pseudonym would be negated had he began the correspondence with "This is the Zodiac speaking". With the entirety of his communications beginning with this phrase, does it lend credence to the notion its absence from the introduction to these three letters, is validation to its concealment in the 18 unsolved characters?  If he hadn't preselected his pseudonym in advance of the July 31st 1969 letters, one could revert back to the notion it was the "cipher killer" attribution that triggered his reply on August 4th 1969. For 35 years starting in 1965, the San Francisco Chronicle and Examiner operated under a Joint Operating Agreement whereby the Chronicle published a morning paper and the Examiner published in the afternoon. The Examiner published the Sunday paper's news sections and glossy magazine, and the Chronicle contributed the features. Circulation was approximately 100,000 on weekdays and 500,000 on Sundays. By 1995, discussion was already brewing in print media about the possible shuttering of the Examiner due to low circulation and an extremely disadvantageous revenue sharing agreement for the Chronicle. Wikipedia. The Bay Area murderer's reply on August 4th, including his pseudonym for the first time, would therefore have been formulated in the mind of the killer from the moment he read the Sunday Examiner publication to his creation of the letter. The Zodiac Killer being born on August 3rd 1969, or early Monday morning on the fourth.
   

However, if he had decided upon his pseudonym in advance of the July 31st 1969 letters and had consciously withheld his pseudonym from his introduction so as to place it within the 18 unsolved characters - then having failed to do so - would be counterintuitive. One could argue that his use of the words "killer" and "murderer" were chosen for purpose, thereby lending credence to a viable solution with respect to the 18 unsolved characters. 

The 18 unsolved characters (if they contain any meaning whatsoever) clearly operate under a different technique of decryption to the other 390 characters. So if the Zodiac Killer didn't happen upon his pseudonym on August 3rd or 4th, then we have the very real possibility that the identity of "Zodiac" does reside in these final 18 characters, to which he alluded to in his address to Vallejo Police Chief Jack E. Stiltz on August 4th 1969. The Zodiac Killer stated "when they do crack it, they will have me".

The Zodiac Killer committed the senseless slayings of David Faraday and Betty Lou Jensen on December 20th 1968. Six and a half months later he would follow this up with a second attempted double murder at Blue Rock Springs Park on July 4th 1969, in which sadly, Darlene Ferrin would succumb to her devastating injuries. Approximately one month later, the Zodiac Killer mailed three letters to the San Francisco Chronicle, San Francisco Examiner and Vallejo Times-Herald announcing that he was responsible for the three murders and attempted murder, while challenging authorities to decode a 408 character cipher. The Zodiac Killer threatened the newspapers, stating "If you do not print this cipher by the afternoon of Fry.1st of Aug 69, I will go on a kill ram-Page Fry. night. I will cruse around all weekend killing lone people in the night then move on to kill again, until I end up with a dozen people over the weekend".  Imagine his horror when the two main newspapers failed to bow to his threats, with the San Francisco Chronicle placing the story on page 4 of the August 2nd 1969 edition, and the San Francisco Examiner demoting him to a lowly page 9 on August 3rd 1969. The problem was further compounded, with Vallejo Police Chief Jack E. Stiltz even questioning the validity of the author and "urged the writer to send more letters, with more facts to prove his connections to the crimes."

The Zodiac Killer in his haste to prove he was the killer responsible for three people, immediately sent a letter to the San Francisco Examiner on August 4th 1969 - and despite the Examiner printing his letter the same day, in which he declared "This is the Zodiac Speaking" and that he "was not happy to see that he did not get front page coverage", imagine his utter disbelief when he discovered that the San Francisco Examiner had again relegated his letter supplying more details of the crimes to page 4. It equally wouldn't have escaped his attention, that on the front page of the same paper it featured the double knife slaying of two young girls from San Jose. Deborah Furlong (14) and Kathy Snoozy (15) had been brutally stabbed while picnicking on a grassy knoll on August 3rd 1969. The Zodiac Killer had now murdered three people, nearly killed Michael Mageau and sent four communications (including three cryptograms), yet he was still unable to command front page coverage. But now he knew exactly what was required - and it was staring him squarely in the face on page one. August 4th 1969 was not only the day he announced his pseudonym to the world, but the day he realized that a brutal stabbing was required to secure himself front page coverage. This was the day the fate of Bryan Hartnell and Cecelia Shepard would be sealed, almost two months in the making.   

Forever the narcissist, the Zodiac Killer couldn't believe his luck when he happened upon three young girls on the shores of Lake Berrryessa by Smittle Creek. I am sure for a brief moment he could see the headlines flash in front of his eyes: "3 Girls Stabbed, Sunbathing Murders, Footprint Clue". However, the Zodiac Killer for whatever reason, decided against the attack, returned to his vehicle and drove away. Fortunately, the three young women from Pacific Union College would escape the wrath of the Zodiac Killer - but he was not done yet. Approximately two hours later and eight tenths of a mile south, the Zodiac Killer would reappear and set his sights on the 1956 White Karmann Ghia of Bryan Hartnell and Cecelia Shepard, before traversing the 510 yard hillside descent to the area of the picnicking couple. Driven by an insatiable desire to secure front page coverage, he proceeded to callously stab the young couple sixteen times before finally returning up the hillside and out of sight. The thoughts of the San Jose murders of Deborah Furlong and Kathy Snoozy - and the headline news they generated - were probably in the forefront of his mind when he approached the Volkswagen Karmann Ghia and pulled the black marker pen from his pocket. He proceeded to write on the car door of Bryan Hartnell's vehicle, to leave you in no doubt that he was mimicking the murders of the two young girls from San Jose. He wrote "Vallejo 12-20-68, 7-4-69, Sept 27-69 - 6:30 by knife". If you ever wondered why he wrote the time 6:30 on the car door, even though he rang in the crime just seventy minutes later, then the newspaper article below may give you a clue. This is the article from the San Francisco Examiner on August 4th 1969 - the very reason why the Zodiac Killer arrived at Lake Berryessa on September 27th 1969 in the first place.  

This annotation of 6:30 on the car door of Bryan Hartnell's vehicle was supposed to mark the time that the young couple at Lake Berryessa failed to return home also.

We know the Zodiac Killer was an avid reader of the newspapers, often replying to law enforcement officers such as Vallejo Police Chief Jack E. Stiltz and Captain Martin Lee, as well as arbitrary content from the newspaper articles themselves. Therefore, would it be any great surprise if he found his pseudonym in the newspapers as well. Covered very briefly on Zodiac Killer Mystery forum and Tom Voigt's old message board, this finding deserved another showing. The Zodiac Killer and the influence of astrology has been widely covered throughout the years, but below we have a column that featured daily over several decades in many newspapers, including the Vallejo Times-Herald throughout the relevant time period of the Lake Herman Road and Blue Rock Springs attacks. The Star Gazer astrology column was created by Clay R. Pollan and ran in over 400 newspapers. He was a newspaper editor and publisher for many years, and founded the Inter-American Features Syndicate in the mid 1940s which distributed Star Gazer and Scram-lets puzzles.

The columns began with "To develop the message for (day), read words corresponding to numbers of your Zodiac birth sign". We mention the Zodiac Killer crosshairs being found in conjunction with the word "Zodiac" on a watch, but here we have a column that would have featured in the Vallejo Times-Herald in 1969, that contained a hidden message within the Zodiac horoscope - and on July 31st 1969, the Zodiac Killer mailed a hidden message in three portions of code, one of which was sent to the Vallejo Times-Herald, and one which was mailed to the San Francisco Chronicle, in which he wrote "In this cipher is my idenity". Is it conceivable that the inspiration for his pseudonym was derived from this Zodiac horoscope, which further inspired him to begin his letter writing campaign with a concealed message?  

Twenty-one years later, could the Zodiac Killer have returned and used the very same technique, when he mailed the Celebrity Cypher. Luis Campos, born in Santiago, Dominican Republic is an inventor, poet and cryptographer who created puzzles and ciphers for the United Features Syndicate of New York, beginning in 1983. He would create six celebrity ciphers a week, featuring famous quotes from well-known people, past and present. The reader had to identify the person and quote from the encoded text. The characters in the cryptograms were deliberately spaced into separate words, as shown below.  

On September 25th 1990, somebody mailed the Celebrity Cypher to the Vallejo Times-Herald, approximately three months before the 1990 'Eureka' card - often associated with the Zodiac Killer. Bearing in mind the 408 cipher mailed to the San Francisco Chronicle, San Francisco Examiner and Vallejo Times-Herald on July 31st 1969, many have pondered whether this postcard was mailed by the Bay Area murderer.

We may now have two sets of Zodiac communications inspired by the hidden messages of Clay R. Pollan and Luis Campos, with the Vallejo Times-Herald the common denominator in both instances. We know the Zodiac Killer derived inspiration from the newspapers, but did this inspiration extend to mimicking the art of hidden messaging? This concept could have extended even further, when the Zodiac Killer designed his infamous unsolved 340 cipher, that may have been taken straight from the Dick Tracy comic and breakfast cereals of children - again receiving widespread publicity in the newspapers.
