On October 22nd 1969, somebody rang the Oakland Police Department to request that either Francis Lee Bailey or Melvin Belli appear on the Jim Dunbar chat show at KGO Radio in San Francisco. Melvin Belli would co-host the morning show at approximately 6:30 am, to which, after a period of inactivity, an unknown male would call and hang up numerous times. The dysfunctional sounding caller claimed he was the infamous Zodiac Killer, a man responsible for at least five murders in the Bay Area of California.

Three people who had heard the Zodiac Killer's voice, Nancy Slover, David Slaight and Bryan Hartnell, were confident that the caller was not the man they had heard during their respective encounters with the killer. A fourth person was absolutely certain, because he was about to compose a 340 cipher denouncing the caller to the Jim Dunbar Show as a fraud, by stating "That wasn't me on the TV show". Many have found it strange that the Zodiac Killer decided to encode this denial, when he could have simply written it into the Dripping Pen card that accompanied the cipher. He clearly expected this cryptogram to be decoded fairly quickly as the message was contemporary, and of diminishing value as the years ticked by.

However, his method of encoding such contemporary information to highlight that it wasn't him on the TV show, thereby confirming that the Jim Dunbar Show caller was an imposter, was to be repeated eighteen months later. Another cryptogram would be mailed to the San Francisco Chronicle in about May of 1971, harboring a hidden message that was again contemporary in nature, while calling out an imposter. This time though, the tables would be turned. On this occasion, the Zodiac Killer would be calling out a "phony", when in realty he was the imposter and the person he was addressing was the real killer. This stemmed from his false claim that he was the murderer of Kathy Snoozy (15) and Deborah Furlong (14) in San Jose. These two young girls were brutally stabbed on August 3rd 1969 and claimed as Zodiac victims when he mailed the Dripping Pen card on November 8th 1969. He would write "Des, July, Aug, Sept, Oct = 7", thereby falsely inflating his victim count to engender more terror over a wider area.

On April 29th 1971, Karl Francis Werner was arrested for the murders of Kathy Snoozy, Deborah Furlong and Kathy Bilek, and his story was covered by Paul Avery on April 30th 1971 under the title of San Jose Student Held in Slaying of Three Girls. 
The newspaper article stated "He was immediately advised of his rights concerning any statements he may make and legal representation to which he is entitled, the detectives said. Werner was then taken to the scenes of the crimes. Late yesterday he was undergoing questioning. The detectives would not reveal what statements, if any, he had made concerning the killings of the three girls". The Zodiac Killer was understandably horrified, because the two murders he had falsely adopted into his victim total for a year-and-a-half, were about to be handed over to someone else. Karl Francis Werner was ultimately charged (and later convicted) of all three murders, but the Zodiac Killer was having none of it, firing off a 148 character cipher and letter sometime in May (see below).

Just like his encoded message in the 340 cipher stating "That wasn't me on the TV show", he would again encode the following message "Tis the Zodiac Speacking. Why can't you stop me. I can't stop killing. Stop listening t(o) phonys. If this is not on your front page in a week I will skin 3 little kids and make a suit from the skin". The Zodiac Killer was responding to the Paul Avery newspaper article, informing everybody that they should pay no attention to Karl Francis Werner and insisted they should "Stop listening to phonys". One can't help seeing the irony of the situation. The Zodiac Killer effectively declared that the caller to the Jim Dunbar Show was a phony because it wasn't him on the TV show, but has now become the phony calling out the real killer - and both of these declarations hidden within cryptograms separated by eighteen months. The Zodiac Killer felt angered enough to dissuade law enforcement in listening to Karl Francis Werner, yet disguised this pertinent message behind a wall of coding, just as he had done on November 8th 1969 with another contemporary message. However, there was one big difference. This latest cryptogram had returned back to the standard left-to-right homophonic technique employed by the 408 cipher. Bearing in mind his 340 cipher was yet to be deciphered - and knowing he wanted to declare Karl Francis Werner a fraud while it still mattered - the Zodiac Killer probably thought it wise to return back to the simplest form of encryption.

Early in December 2020, the 340 cipher was cracked by David Oranchak, Sam Blake and Jarl Van Eycke, which revealed the message shown below. Despite the fact the message left many rather deflated because of its banality, hoping it would reveal so much more, the message contained in the Dripping Pen card and the following Fairfield letters appear to show a running theme. It was recently highlighted how the 38 character code in the December 7th 1969 communication (1st Fairfield letter) showed a distinct correlation to the 340 cipher. Here is a brief recap:

If a Zodiac impersonator had created the 38 character code, this hoaxer would have had to guess that by separating the prominent ZO∆AIKꞮ+ characters on the bottom line of the 340 cipher, into AIKꞮ+ on the bottom line of the 38 character code, he would be reducing these characters to create something meaningful. He apparently did. By separating these characters into the five visible at the end of the 38 character code, he created the word "death", just like the solved 340 cipher. Druzer, an excellent Zodiac researcher, pointed out the same thing, stating "The most curious/compelling feats are that the author isolated actual words, most notably death, and that he refrained from copying Zodaik, which would certainly be expected of a hoaxer". In other words, he dismantled the ZO∆AIK element, while leaving Ɪ+ in place, to form "death" as the final word on the 38 character code. This appears to show knowledge of the hidden message in the 340 cipher. But there is so much more in the Fairfield letters that harks back to the Dripping Pen card and 340 cipher.

Despite stating in the above message he now had enough slaves to work for him in paradice, he would ultimately decide to "kill again" on December 7th 1969, in accompaniment to his brief 38 character code. The Zodiac Killer would never use the standalone word "life" outside of the November 8th and December 16th communications, yet he would end the 340 message with "life will be an easy one in paradice [death]", and begin the December 16th 1969 communication (2nd Fairfield letter) with "I just need to tell you this state is in troulbe, I will go for the Goverment life".

The Dripping Pen card containing the 340 cipher stated "Could you print this new cipher in your frunt page?", whereas the wording "you better print" preceded the small 5/9 character code in the December 16th 1969 letter. The decoded message in the 340 cipher (unknown to anyone until December 2020) began in mocking fashion, stating "I hope you are having lots of fun trying to catch me", while the message immediately beneath the small code in the December 16th 1969 letter stated "you will not catch me". It was almost as though the Zodiac Killer was replying to himself just over five weeks later, in absence of his cipher being solved.

On October 22nd 1969, the Oakland Police Department took a call in the early morning hours from somebody claiming to be the Zodiac, 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. Melvin Belli agreed to appear on the show to which a man would eventually contact via telephone, claiming not only his name was 'Sam', but also by inference that he was the infamous Zodiac Killer. It was very quickly determined from Nancy Slover, David Slaight and Bryan Hartnell that the caller to the TV show wasn't the Zodiac Killer, which was confirmed by the decoded 340 message, which read "That wasn't me on the TV show". However, the Zodiac Killer didn't expand on who the person was that made the phone call to the Oakland Police Department. Whether he was leaving this open to speculation deliberately, nobody knows, but Oakland would feature in his murder destinations on December 16th 1969. This was the only time this city would feature by way of written text in any of the Zodiac Killer's communications, and it came just five weeks after the Bay Area murderer encoded the denial of "That wasn't me on the TV show". Was it a subtle admission that he did make the Oakland phone call to police and was now promising to murder eight of them, hence the renewed contact with Melvin Belli just four days later providing a piece of Paul Stine's shirt?

There are three things a hoaxer should not have known regarding the decoded 340 cipher message. [1] He shouldn't have known that by separating ZO∆AIKꞮ+ into AIKꞮ+ that it would produce the word "death" at the end of both codes, and provide a common link between the two. [2] He shouldn't have known that the opening line of the 340 message read "I hope you are having lots of fun trying to catch me", when he replied "you will not catch me" only 38 days later, unless you maintain that this is a coincidence. [3] He shouldn't have known that the Oakland inspired TV show had featured as a denial by the Zodiac Killer in the message, when he listed Oakland in the list of his murder sites.

The word "death" could be decoded using the Zodiac key through both the Z340 and Z38 within 29 days of one another. The December 16th 1969 letter also contained a configuration of four smaller crosshairs positioned around larger crosshairs, similar to the configuration of By Knife, By Gun, By Rope and By Fire on the Halloween card mailed on October 27th 1970. However, on this occasion the design was preceded by five characters. Could this be the word "death" once again, mirroring the Tim Holt comic book which likely inspired the design of the Halloween card in the first place? Anyway, "I thought you would nead a good laugh before you hear the bad news. Ha! Ha! Ha!"   

In the early morning hours of October 22nd 1969, somebody claiming to be the Zodiac Killer called the Oakland Police Department and requested that Francis Lee Bailey or Melvin Mouron Belli appear on the Jim Dunbar Show at KGO Radio in San Francisco, to which he would ring in. Somebody did ring the chat show, but this caller was later identified as mental patient, Eric Weill. However, we still don't know to this day whether the original caller to the Oakland Police Department was the Zodiac Killer or not, because the genuine Zodiac Killer only stated "That wasn't me on the TV show" in his now decrypted 340 cipher. At no point did he deny being the caller to the Oakland Police Department.

Probably the most important question to ask, is why would the Zodiac Killer choose to ring the Oakland Police Department above any other. There appeared no connection between the Zodiac Killer and Oakland prior to October 22nd 1969. However, this was also the case on October 15th 1969, when the Zodiac Killer almost certainly phoned the Santa Rosa Police Department to threaten schoolchildren on buses, who then implemented the routine checking of every school bus for hidden bombs. This caller, claiming to be the Zodiac Killer, was threatening schoolchildren two days before the details of "School children make nice targets, I think I shall wipe out a school bus some morning" was released into the newspapers.

On October 21st 1969, the day before the Oakland Police Department call, somebody claiming to be the Zodiac Killer rang the Palo Alto Times newspaper. The Palo Alto Times reported on October 22nd 1969, that 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 caller to the Palo Alto Times said he intended to "pick the kids off as they get on the school bus". 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. This would come only six days after the Santa Rosa threat on schoolchildren. The caller also stated to the Palo Alto Times that he had left San Francisco "because I'm too hot there". On December 8th 1969, somebody claiming to be the Zodiac Killer rang commercial radio station KTOK in Oklahoma City, claiming he left California "because it got too hot for me". There was a further call on December 19th 1969, the day before the Melvin Belli letter, threatening "I am going to kill five of you officers and a family of five between now and Monday". This call was received by Shirley Searey, a police dispatcher at the San Jose Highway Patrol.

Captain Martin Lee stated, after the Zodiac Killer's October 13th 1969 letter: "His boast of being in the area we were searching was a lie. We had the whole area flooded with lights. We had seven police dogs and a large number of patrolmen searching the area tree by tree and bush by bush. The dogs are the best in the country". Captain Lee added that Zodiac's failure to mention the dogs and floodlights was proof "he wasn't anywhere in the vicinity". The Zodiac Killer responded on November 9th 1969 with "I have grown rather angry with the police for their telling lies about me. The dogs never came with in 2 blocks of me + they were to the west + there was only 2 groups of parking about 10 min apart then the motor cicles went by about 150 ft away going from south to north west".

However, this ire likely began on October 15th 1969, when the San Francisco Chronicle failed to publish his threat on schoolchildren, resulting in his phone call to the Santa Rosa Police Department. The call to Oakland Police Department on October 22nd 1969 may have been triggered by these perceived slights from law enforcement. By avoiding the San Francisco Police Department and calling the Oakland Police Department on October 22nd 1969, the Zodiac Killer could request a prominent attorney to represent him on the Jim Dunbar Show, and set the record straight on the misinformation and lies spoken about him by Captain Martin Lee to the San Francisco Chronicle. This TV audience on the popular Jim Dunbar Show in San Francisco may have been the ideal way to set the record straight, circumventing the San Francisco Police Department and San Francisco Chronicle and receiving maximum exposure. Ultimately, the Zodiac Killer may have had second thoughts, surmising that it could have led to somebody identifying him. This hesitancy opened the door to hoaxer Eric Weill.

Despite the phone call to the Jim Dunbar Show having been roundly dismissed as the Zodiac Killer "by three who knew", the murderer of five still felt compelled to disassociate himself from being the caller to the TV show, by mailing a cryptogram and greeting card on November 8th 1969. If the Zodiac Killer had rang the Oakland Police Department on October 22nd 1969 with the intention of appearing on the Jim Dunbar TV show and setting the record straight concerning Captain Martin Lee and the San Francisco Police Department - then having not done so - one would have expected his next communication to do exactly that. Therefore, it's no surprise that the Bus Bomb letter on November 9th 1969 was the Zodiac Killer's longest communication of them all, attacking the police with the venom he so wanted to do with a captive TV audience. The two communications on November 8th 1969 and November 9th 1969, inextricably bound by his failure to appear on the Jim Dunbar Show just over two weeks earlier.

The phone calls wouldn't stop there, when Daniel Williams (24), a Salesian High School teacher, started to receive malicious phone calls to his 1234 Bush Street, Martinez residence on October 23rd 1969. These calls continued for ten days and culminated with somebody breaking into his residence on November 2nd 1969 and lacing his 7-Up soft drink with enough arsenic to kill. The caller, claiming to be the Zodiac Killer, told Daniel Williams over the phone that he "had gone to a Martinez school in search of victims but left when he found police there", mocking law enforcement by stating “I’m too smart for them". This was considered particularly relevant because of the language Zodiac adopted on November 9th 1969 in the Bus Bomb letter mailed to the San Francisco Chronicle of "The police shall never catch me, because I have been too clever for them".

On Wednesday, November 5th 1969, somebody rang the Martinez Police Department at 12:30 am stating "There's going to be a shooting at 1234 Bush Street", before immediately hanging up. The threat to find victims at a Martinez school, coupled with the menacing phone calls, were not dissimilar to recent Zodiac activity during the month of October. After the threat to shoot Daniel Williams at his residence, police instigated surveillance in the immediate area of Bush Street for the remainder of that morning, but no suspicious activity was detected. The next Zodiac Killer communications would be postmarked just two and three days later, with the promise of more bad news and a victim count left dangling at the end of October. If the perpetrator of the crimes inflicted upon Daniel Williams wasn't the Zodiac Killer, then it was a pretty determined hoaxer claiming to be him. The call to Oakland Police Department was made on October 22nd 1969, with the threats on Daniel Williams beginning just a day later, on October 23rd 1969. The Salesian High School where Daniel Williams worked, only thirteen miles north of the Oakland Police Department. When we place all of this in context, does it indicate that the Zodiac Killer was likely the caller to Oakland Police Department on October 22nd 1969, or did Eric Weill just spontaneously call law enforcement because he had nothing better to do at the time? 

Larry Lamotte (60), a former news director at commercial radio station KTOK in Oklahoma City, drowned off the coast of Florida in 2003 while swimming at Grayton Beach. There was nothing suspicious about his death, but Larry Lamotte spoke to the San Francisco Chronicle in an article featured on December 8th 1969. A man claiming to be the Zodiac Killer phoned a talk show host at KTOK on December 7th 1969 doing an awfully good impression of the man who rang the Jim Dunbar Show on October 22nd 1969, stating he left California because "it got too hot for me".

On October 22nd 1969, the Oakland Police Department took a call at 2:00 am from somebody claiming to be the Zodiac Killer, 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. Melvin Belli agreed to appear on the show, to which a man would eventually contact via telephone, claiming not only his name was 'Sam', but by inference that he was the infamous Zodiac Killer. The call was later attributed to hoaxer, Eric Weill, whose  father's name just happened to be Sam.

Larry Lamotte thought that the man on the phone to KTOK appeared to be impersonating the caller who rang the Jim Dunbar Show on October 22nd 1969, so it's quite a coincidence that on the same day (October 22nd 1969) the Palo Alto Times newspaper carried a news story regarding a phone call from a man claiming to be the Zodiac Killer, stating he left San Francisco "because I'm too hot there".

The Palo Alto Times reported 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 caller to the Palo Alto Times said he intended to "pick the kids off as they get on the school bus." 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. Handwriting tests and descriptions of two victims who survived have convinced police that the same person. 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 75 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.

We have two phone calls separated by one-and-a-half months, with both callers claiming they left the Bay Area because "because I'm too hot there" and "it got too hot for me". Either it's coincdence (and both are hoaxers), the second caller recalled the phrase used by the first caller one-and-a-half months earlier (and one caller may be Zodiac), or both phone calls were made by the Zodiac Killer, who was simply enjoying the terror he was inflicting on the people of northern California. 

On October 22nd 1969 the Oakland Police Department took a call at 2:00 am from somebody claiming to be the Zodiac Killer, 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. Melvin Belli agreed to appear on the show, to which a man would eventually contact via telephone, claiming not only his name was 'Sam', but by inference that he was the infamous Zodiac Killer.

The Desert Sun newspaper reported "SAN FRANCISCO (UPI)- A man who said he was Northern California’s "Zodiac killer” of five persons talked with a San Francisco attorney by telephone today while television viewers listened in. Attorney Melvin Belli also talked with the man on another, private line, then said he had arranged to meet with him. Police said they had no way of knowing whether the man was "Zodiac,” who has boasted in notes of five killings in the San Francisco Bay area in the last nine months. But they said they did not consider the caller a prankster. The caller first called a police station at 2 a.m. and said he wanted to get in touch wbth either Belli, the attorney who once defended Jack Ruby in Dallas, or Boston lawyer F. Lee Bailey. He asked that one of them be on the morning talk show of disc jockey Jim Dunbar on KGO-TV. Police contacted Belli, who went to the studio. The man, who said his name was "Sam,” called shortly after 7 a.m and said he was the ‘‘Zodiac killer.” He hung up immediately, but called back a total of 12 more times. While Belli and Jim Dunbar, host of the show, pleaded with him to give himself up, the caller said he suffered from recurring headaches and impulses to kill. Finally, the caller agreed to have Belli go to the San Francisco district attorney’s office to see if prosecutors would assure him they would not ask for the death penalty. Belli said that in another call off camera, the man had agreed to meet him at a secret location after the conference with the district attorney".

In January of 1970, a person claiming to be Zodiac rang the Belli residence, spoke with his housekeeper Erna and requested to speak with the flamboyant lawyer, only to be told he was unavailable and out of the country. The caller replied "I can't wait, today's my birthday". This interaction was detailed in a partially redacted FBI file on January 14th 1970. The phone call would have been placed in the days before this urgent request, labeled "instant date January 14th". On February 18th 1970, the caller to the Jim Dunbar Show was identified by San Francisco Police as Eric Weill. They contacted the FBI with the details, but this information did not appear in the newspapers. Eric Weill was almost certainly the responsible for both the Jim Dunbar Show call and the call to Bellii's residence, stating "I can't wait, today's my birthday". Eric Weill was born on January 10th 1940 and his father's name was "Sam".

San Francisco Chronicle reporter, Paul Avery, would later document the Jim Dunbar Show phone call in 1971 (see below), misspelling the name "Eric Weill" to "Eric Weil", accidentally omitting one of the L's. The Zodiac Killer followed the San Francisco Chronicle newspaper coverage throughout his campaign of terror, so couldn't have failed to know the correct spelling of Paul Avery which sat under the title of many articles. So it was rather curious to see that the Zodiac Killer had seemingly added one of the L's back, by inserting it into the reporter's name, changing "Paul Avery" to "Paul Averly" in both the October 27th 1970 Halloween card and March 22nd 1971 Pines card. If the spelling error by the Zodiac Killer was deliberate, could it have been a subtle dig at Paul Avery for his misspelling of Eric Weill in the run-up to this report. However, for this to be the case, Paul Avery would have needed to know the identity of Eric Weill sometime between February 18th 1970 and the writing of this report in 1971, have previously misspelled the name - and the Zodiac Killer to have known this. The only reason for this speculation, is the idea suggested by some, that the Zodiac Killer may have worked for the San Francisco Chronicle newspaper and hence his numerous communications mailed to them. This notion would rely heavily on the "Paul Averly" misspelling being deliberate and done for purpose. The problem with this train of thought, is the Zodiac Killer posed as an illiterate communicator throughout his correspondence, so singling out one specific section has its drawbacks.

But there is a strong possibility that the "birthday call" was placed on January 10th 1970, with Eric Weill likely believing, that being honest about his birthday would never lead to his identification. It didn't, but the resultant tracing of the calls to him and the FBI files detailing the "birthday call" just prior to January 14th 1970, further strengthening the case against him. The choice of "Sam" as his chosen name on the Jim Dunbar Show call may also be very close to home.

At approximately 2:00 am on October 22nd 1969, somebody called the Oakland Police Department claiming to be the Zodiac Killer and wanting to appear on the KGO-TV Jim Dunbar Show that day. The caller requested that prominent attorney Francis Lee Bailey take his call on the television program, but added that if he was unavailable, he would accept the high profile San Francisco lawyer, Melvin Mouron Belli as an alternative. During the beginning of the call (6:30 am) to the Jim Dunbar Show the person identified himself as "Sam" when asked for a less ominous name. Despite the Oakland Police dispatcher believing that "Sam" was the same individual that they had spoken to, some people have still questioned whether the real Zodiac Killer called the Oakland Police Department at 2:00 am, but his place was taken by a mental patient called Eric Weill, identifying as "Sam".

It is fairly clear that the caller to the Oakland Police Department was the same man who rang in to the Jim Dunbar Show, and the Zodiac Killer was never in the loop. One reason for believing this to be the case, may lie in the choice of the name "Sam" as an alternative for the "Zodiac Killer". Why would Eric Weill choose the name "Sam"?

The caller to Oakland Police Department made a specific request for criminal defence attorney Francis Lee Bailey, who was previously hired by the brother of Sam Sheppard, found guilty in the brutal murder of his wife Marilyn in 1954. In 1966, F. Lee Bailey successfully argued before the U.S. Supreme Court that Sheppard had been denied due process, winning a re-trial. A not guilty verdict followed. Was this the inspiration behind Eric Weill's choice of attorney and the name "Sam", both inextricably linked by a high profile court case a few years earlier. However, this was getting on for three years ago.

In August 1969, just two months prior to the Oakland Police Department and Jim Dunbar Show calls, Sam Sheppard debuted as a professional wrestler against Wild Bill Scholl - entering under the stage name of "Killer" Sam Sheppard. Therefore, it is quite ironical that the caller on October 22nd 1969 had asked for an attorney who successfully defended Sam Sheppard, who then identified as "Sam" on the Jim Dunbar Show as a replacement for the ominous "Zodiac Killer", just two months after Sam appeared in the "ring" as a "killer". You couldn't write the script.

Sam Sheppard wrestled over 40 matches before his death in April 1970, including a number of tag team bouts with professional wrestler George Strickland as his partner. His notoriety made him a strong draw. 

In the November 9th 1969 'Bus Bomb' letter the Zodiac Killer was clearly agitated by the response he received after mailing the Paul Stine letter on October 13th. In it he stated "This is the Zodiac speaking up to the end of Oct I have killed 7 people. I have grown rather angry with the police for their telling lies about me. So I shall change the way the collecting of slaves. I shall no longer announce to anyone. When I committ my murders, they shall look like routine robberies, killings of anger, + a few fake accidents, etc". The newspaper article that upset him featured Chief of Police Martin Lee, who stated in the San Francisco Chronicle article on October 18th 1969 entitled 'Zodiac Called a Clumsy Criminal,' that Zodiac possibly left his fingerprints on the taxicab, allowed himself to be spotted by three teenagers, and failed to kill all his victims. He went on say "His boast of being in the area we were searching is a lie. We had the whole area flooded with lights. We had seven police dogs and a large number of patrolmen searching the area tree by tree and bush by bush. The dogs are the best in the country. A mouse couldn't have escaped our attention".

The question was; had the Zodiac already attempted or carried out a crime after the October 18th 1969 article that was designed to look accidental or natural, but had possibly failed. After all, his victim count remained at seven by the end of October, which he corroborated in the Dripping Pen Card on November 8th. To do so, we would have to look at attempted crimes claimed by the 'Zodiac Killer' between October 18th and November 8th, in a relevant location.

As seen on the left, a Salesian High School teacher, Daniel Williams had his house broken into, but nothing was taken. A man claiming to be the Zodiac Killer made several threatening phone calls beginning on October 23rd 1969, culminating with the caller saying "You're the dead duck" on November 2nd 1969. Later that day, Williams took a drink from the refrigerator, but fortunately spat it out after noticing a metallic taste. The drink contained enough arsenic to kill.

This in all likelihood is not the Zodiac Killer, however, the targeting of a school teacher is interesting, bearing in mind a Salinas High School teacher, Donald Harden cracked his first cipher, and his 'Dripping Pen' card and second cipher was to arrive in just six days. It could also be argued that this attempted murder - had it been successful - may have looked 'accidental' as the Zodiac would state in the 'Bus Bomb' letter.

Daniel Williams residence was situated at 1234 Bush Street, Martinez, only 9 miles from the location of Zodiac's first crime at Lake Herman Road.
The mystery man during one of his calls talked of "killing the lady in the blue house," but as of yet the meaning behind this utterance is undetermined. 

Bearing in mind the October 22nd 1969 Jim Dunbar radio show, in which Zodiac was supposed to call in, it is hardly surprising we may get a crank call by somebody claiming to be Zodiac beginning on October 23rd 1969. The only difference here, was it appeared the caller was prepared to back up his threat with action. The original caller to the Oakland Police Department at 2:00 am on October 22nd 1969 may however, not be the same person as the hoaxer, who ultimately called the Jim Dunbar show and spoke to Melvin Belli.

​The phrase 'dead duck' may originate from "Never waste powder on a dead duck," first recorded in 1829. Bearing in mind the use of arsenic powder, an ironic choice of words. 

On October 22nd 1969, the Oakland Police Department took a call in the early morning hours from somebody claiming to be the Zodiac Killer, 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. Melvin Belli agreed to appear on the show, to which a man would eventually contact via telephone claiming not only his name was 'Sam', but also by inference that he was the infamous Zodiac Killer.

Three people had heard the voice of the Zodiac Killer, Bryan Hartnell who survived the brutal attack at Lake Berryessa in Napa County, and two police dispatchers, Nancy Slover and Dave Slaight, who all categorically stated that the man called 'Sam', who rang in to the Jim Dunbar show was not the same voice they had recalled from the Blue Rock Springs and Lake Berryessa attacks and therefore not the Zodiac. It was believed that Eric Weill, a mental patient was responsible for the hoax call to the Jim Dunbar show in the October of 1969. It is unknown whether the original caller to the Oakland Police Department was the real killer. However, just three-and-a-half months later on February 5th 1970, a second phone call would arrive during an on air interview by Jim Dunbar with a movie producer. The caller again claimed to be the Zodiac Killer.  

SAN FRANCISCO (UP!)- A man claiming to be the Zodiac killer of five persons held another on-the-air conversation today with television personality Jim Dunbar. Two police inspectors closeted themselves with Dunbar at station KGOTV immediately after the one-sided conversation, which consisted mainly of Dunbar asking questions and repealing fragments of answers.

“When headaches come on, you kill to get relief?” Dunbar asked at one point. “What other stuff you been on besides glue?”. Last October 23, Dunbar and attorney Melvin Belli, a guest on his early morning talk show, held a bizarre conversation with a man who said he was Zodiac. Belli set a meeting with the man, who did not show up. Today's call interrupted an interview by Dunbar with a movie producer. Police believe Zodiac is responsible for five killings in Northern California in the last 13 months. In a series of taunting cryptograms and letters to newspapers and police he has boasted of killing seven and threatened to kill more. Dunbar’s side of the conversation was recorded but not the other voice. The station said something had gone wrong with the monitor on the caller’s voice.

The conversation ran, in part, like this: "What other stuff you been on besides glue? Oh, gas? flow do you get? Oh. Do you still have parts of the shirt you sent the newspaper? Oh. . , . Did the victim make a move on you? In other words, you thought he was going to move? .... Did you have the 9 mm gun? Oh, three guns. What, four guns? How could you conceal four guns? ‘‘When headaches come on, you kill to get relief? . . . Chief evil is what ? . . . Sonny Barger of Hell’s Angels?. Meridith Hunter—you are going to do it yourself to bring justice on the Meridith Hunter murderer? Oh. . . Were you anywhere near Altamont for the rock concert? Oh, you knew it was a hoax? . . . You weren’t there?. . . . “You hate Yellow Cabs? . . . Is that why you killed Paul Stine? . . . You want Belli to represent you? . . . You want life in prison, not death?. m m Why Friday 13th? Is that a bad day? ... You say you’re a tranquility smoker? ... Oh, for 10 years? How can you say that when you’re only 18? . . . What usually brings your headache on? You go without sleep? Months? .. . Are you gassed now? . . . Why do you mix booze with drugs? "Why don’t we get together before Friday 13th? ... You say southwest corner of the Tonga Room? You have a girl? Oh, two. Pretty young, you say, 21 and 24? . . . Tell me one thing you told Belli that I don't know, or wrote to him that nobody else knows. I won't repeat it.”
