OLD NORSE FOR KILL

9/30/2019

 
Picture
In previous articles I have attempted to show that the February 3rd 1974 SLA Letter was mailed by the Symbionese Liberation Army, along with the Citizen Card and Red Phantom Letter. However, the Exorcist Letter mailed on January 29th 1974 (five days earlier) is difficult to ascertain whether it was mailed by the Zodiac Killer or the left-wing militant group. The SLA Letter stated "Dear Mr Editor, Did you know that the initials SLA (Symbionese Liberation Army) spell "sla", an old Norse word meaning "kill". a friend". Many have argued that the author of this correspondence incorrectly attributed the word "kill" to "sla" in Old Norse - but this is not true. 

Sla in Old Norse can be inferred as "kill", to which the author of this communication claimed. Sla in Old Norse means "to strike" or "to smite". The archaic use of the word "smite" as shown by the Merriam-Webster dictionary, defines "smite" as to kill or severely injure. In Wiktionary it is shown as the ability to strike down or kill with deadly force. So (in archaic usage like Old Norse) "sla" means "smite", and "smite" is used as "kill". Here is a PDF of Old Norse from York University, compiled by Ross G. Arthur. This will confirm that the author of the SLA Letter was correct all along. The author didn't write "Dear Mr Editor, Did you know that the initials SLA (Symbionese Liberation Army) spell "sla", an old Norse word with a direct translation to "kill". a friend". They used the word "meaning", which is something that it expresses or represents - and "sla" can represent or express the word "kill" through "smite". The whole communication was dedicated to highlighting the word "kill" through Old Norse.

Old Norse was a North Germanic language that was spoken by inhabitants of Scandinavia and their overseas settlements from about the 9th to the 13th centuries. The Proto-Norse language developed into Old Norse by the 8th century, and Old Norse began to develop into the modern North Germanic languages in the mid- to late 14th century, ending the language phase known as Old Norse. These dates, however, are not absolute, since written Old Norse is found well into the 15th century. Old Norse was divided into three dialects: Old West Norse, Old East Norse, and Old Gutnish. Old West and East Norse formed a dialect continuum, with no clear geographical boundary between them. For example, Old East Norse traits were found in eastern Norway, although Old Norwegian is classified as Old West Norse, and Old West Norse traits were found in western Sweden. Most speakers spoke Old East Norse in what is present day Denmark and Sweden. Old Gutnish, the more obscure dialectal branch, is sometimes included in the Old East Norse dialect due to geographical associations. It developed its own unique features and shared in changes to both other branches. Inscriptions have become synonymous with Runes. Wikipedia.

If the Symbionese Liberation Army were the architects of the SLA Letter, then the whitewashed symbols of the Exorcist Letter from the San Francisco Chronicle newspaper on January 31st 1974 would only be known to the designer of the SLA Letter, If those symbols also highlighted the word "kill" or the verb "to kill", we could conclude the SLA Letter was simply the answer to the Exorcist Letter. There have been several examples of people trying to compare runic symbols to the Halloween Card and Asian style characters to the Exorcist Letter. Kevin Robert Brooks, an avid Zodiac researcher, used neither in decoding the Exorcist Letter to spell the words "To Kill", and thereby tying the January 29th and February 3rd communications into one neat bundle (shown below).  

Picture
Bearing in mind the Old Norse element of the SLA Letter, I thought I would make a provisory attempt at looking for a runic connection to the Exorcist Letter that complimented Kevin Robert Brooks solution. There is an eastern Rhaetian language that used runic symbols. It is clear that in the centuries leading up to Roman imperial times, the Rhaetians had at least come under Etruscan influence, as the Rhaetic inscriptions are written in what appears to be a northern variant of the Etruscan alphabet. The ancient Roman sources mention the Rhaetic people as being reputedly of Etruscan origin, so there may at least have been some ethnic Etruscans who had settled in the region by that time. In the diagram below I have taken the Rhaetian symbols and their corresponding English letters to spell the combined wording T'Kill.

The letters K, I and L mimic the symbols used by Kevin Robert Brooks to form the word "kill", and the exclamation type symbol is used to form "T'Kil", thereby phonetically creating the sound "To Kill" using runic symbols (running from left to right on the Exorcist Letter). This last section is not claiming an answer in the slightest, just searching for a correlation between ancient or archaic characters in keeping with Old Norse from the following communication.

FBI FILES: THE ZODIAC KILLER, SLA AND KENNEDY THREATS

9/29/2019

 
The Zodiac Killer disappeared sometime in 1971, only to reappear on February 3rd 1974 and mail the SLA Letter to the San Francisco Chronicle the day before the Symbionese Liberation Army kidnapped media heiress, Patricia Campbell Hearst on February 4th. Remarkable timing from the Bay Area murderer. Not only that, but seven days later on February 10th 1974, the real Symbionese Liberation Army sent a communication targeting the Hearst Family that was intercepted at the Burlingame, California, U.S. Postal Annex, addressed to Santa Inez Avenue in Hillsborough. This too began with the wording "Dear" and signed off with "a friend". Both were withheld from the newspapers. This casts huge doubt on the Zodiac Killer being responsible for the SLA correspondence, unless you are of the opinion that the Zodiac Killer typed up the February 10th 1974 communication. 
Picture
With much gratitude to Rubislaw32, a regular contributor to this site, another communication has been unearthed from the Symbionese Liberation Army Hearnap Files. This picture postcard (shown below) was mailed to Richard Nixon and the White House, postmarked 974 PM 23 MAY 1974. It read "Dear King, We know where Patty Hearst is but wait till we get your daughter. A concerned citizen for freedom."  The writing is extremely scattergun, exhibiting some similarities to the April 30th 1967 Bates' letters, but just like the SLA Letter, the timing of this postcard with respect to the Badlands or Citizen Card (purportedly mailed by Zodiac) is again relevant.

The Citizen Card was mailed on May 8th 1974, so this postcard was sent approximately 15 days later. The Citizen Card read in part "
Why don't you show some concern for public sensibilities and cut the ad? A citizen". The Zodiac Killer supposedly wrote the SLA Letter on February 3rd 1974, beginning the correspondence with "Dear* and signing it off with "a friend", which was mimicked by the Symbionese Liberation Army on February 10th 1974, who also began their communication with "Dear" and signed off with "a friend". Then came the supposed Zodiac Citizen Card on May 8th 1974 expressing "concern" for public sensibilities and signing off with "a citizen", which was seemingly again mimicked by the Symbionese Liberation Army on May 23rd 1974, beginning their communication with "Dear" and signing off with "a concerned citizen".  Two consecutive communications accredited to the Zodiac Killer bearing an uncanny similarity to two Symbionese Liberation Army communications, separated by only 7 and 15 days. Do the math. Either the Zodiac Killer didn't write the February 3rd and May 8th communications, or the Zodiac Killer was getting in on the act of writing to the Hearst Family on February 10th 1974 and making threats to President Richard Nixon on May 23rd 1974. 

The Zodiac Killer was linked to the Riverside murder of Cheri Jo Bates on October 30th 1966, as well as the Riverside Desktop Poem, Confession Letter and Bates' letters. The Riverside Desktop Poem threatened murder and pronounced "Wait till next time", while one of the Bates' letters addressed the father of Cheri Jo Bates and threatened "She had to die, there will be more".  The Richard Nixon Postcard contained elements of both, with the scruffy capitalized writing below evident in the Bates' letters.

Color version of postcard
A series of 5 letters were mailed to Edward Kennedy, Joseph P. Kennedy, Ethel Kennedy and Adlai Stevenson in the June and July of 1968 with various threats - but bearing in mind the Richard Nixon Postcard above and the initial comparison to the Bates' letters - these threats contained one particular correspondence that mimicked the trinity of Bates' letter, when a communication was addressed to Edward M. Kennedy in June of 1968, just over one year later (see below). It stated "Jack had to die. Bobby had to die. Teddy has to die". The Riverside communications thrice stated Bates "had to die". 

In a second letter postmarked Boston, Mass on June 29th 1968 to Edward M. Kennedy, it stated "You will die if you run for Pres or VP. We hate Kennedys".

Here we have a selection of communications purportedly from the Zodiac Killer, Symbionese Liberation Army and a third person mailing threats to officialdom and presidential candidates. But which communications belong to which? Did the Zodiac Killer really return in 1974 and fire off four correspondences to the San Francisco Chronicle, or were all or some mailed by the Symbionese Liberation Army? Did the threat on "goverment life" in the December 16th 1969 Faifield Letter begin one year earlier with the Kennedy communications, thereby bridging the gap between Riverside and the Bay Area? I shall let you decide.

A big thanks to Rubislaw32 with his help in finding valuable communications in the Hearnap and Kennedy FBI files. Without his assistance, this article would not have been possible.      

THE MURDER OF NIKKI BENEDICT

9/27/2019

 
PictureNikki Alexandra Benedict
Nikki Alexandra Benedict (14) had left her friend Kathie Gomski's house in Halper Road, Poway on May 1st 1967 shortly after 6:00 pm, to walk the 2 1/2 mile journey to her home at 13530 Olive Tree Lane, when approximately 25 minutes into her journey her life was cruelly snatched away. She was just passing the intersection of 12784 Poway and Carriage Road, traveling along a dirt pathway that straddled the Poway Road, when a man laying in wait leapt from a grassy depression and viciously attacked the young teenage girl with a short-bladed knife. She had a knife wound to her neck and bruises on her elbows and knees, but the fatal injuries were two stab wounds that penetrated her heart. The young girl did not succumb to her injuries immediately, with a trail of blood extending 200 yards to the west side of Carriage Road as she desperately sought help near a local shopping center. At approximately 6:30 pm, an 11-year-old boy, Ronald Fisk, discovered the critically injured girl and raced away on his bicycle to seek help from his father, who worked at a nearby market store. Unfortunately, despite the best efforts of responding personnel, Nikki Benedict would be pronounced dead upon her arrival at Palomar Hospital.

Nikki Benedict would usually travel the 2.3 mile journey home from Meadowbrook Junior High School on the school bus, however, on this Monday she visited her friend Kathie in Halper Road to discuss an art project. Kathie was planning to escort Nikki along the initial part of her journey home, but was unable to accompany her friend because she had to stay home for her dinner. Nikki Benedict would have traveled south, before heading east alongside the Poway Road toward home, or traveled southeast from Halper Road to the intersection of Poway and Carriage Road, near to where her body was discovered. Whether she had been trailed by her attacker or had walked into his path has yet to be fully determined, but the attack was swift and deadly, with no robbery or sexual interference apparent. One eyewitness recalled a white man fleeing the scene, although no solid suspects have subsequently emerged from this sighting and the case has remained relatively trapped in time for just over 52 years.

PictureCheri Jo Bates
Links have been forged to the Riverside murder of Cheri Jo Bates on October 30th 1966, some six months earlier. She too was savagely attacked with a short-bladed knife, with the Zodiac Killer belatedly laying claim to her murder on March 13th 1971 when he wrote to the Los Angeles Times, stating "I do have to give them credit for stumbling across my riverside activity, but they are only finding the easy ones, there are a hell of a lot more down there". Poway, San Diego is 83 miles south of Terracina Drive in Riverside, where Cheri Jo Bates body was ultimately discovered on Halloween morning by Riverside City College caretaker, Cleophus Martin.

I always find it helpful to provide a map regarding any crime scenes, so below I have identified the relevant locations in the murder of Nikki Benedict, despite the fact the topography has changed over the last half-century.

On the map I have highlighted a second attack - that of Patricia Lee Kuzara (7), who was murdered while walking home on Saturday, September 28th 1974, with her badly beaten body discovered the following morning in a field just off Midland and Hilleary Road, Poway, just alongside the First Baptist Church. She was just a few blocks from her home in Putney Road when the attacker struck, inflicting numerous blows to her head with a blunt instrument. She had been staying with family friends/babysitters approximately 2 1/2 miles away and had left shortly before dusk (6:30 pm) according to the friends. Why on earth a babysitter would allow a seven-year-old girl to walk this distance unaccompanied I have no idea? Four days after her body was discovered, a 40-inch long angle iron with pieces of wood attached was found on Hilleary Road. It was believed to have been innocently moved from its original location in the field. 
PicturePatricia Lee Kuzara
Sergeant Doug Clements was of the opinion that the killer probably lived nearby, creating understandable apprehension in the local community. The killing of Patty Lee Kuzara was only a mile from the murder site of Nikki Benedict, and both were attacked alongside the Poway Road in a grassy area. Both young girls lived only 660 meters from one another. Investigators in a press release stated that the Patty Lee Kuzara murder appeared sexually motivated, so whether any connection exists to the murder of Nikki Benedict is sheer speculation. Had the murderer of Nikki Benedict failed to complete his objective that day because of the vigorous defence she displayed in countering his attack, and therefore had chosen easier prey in his subsequent attacks? (if any). Of course, the two may be totally unrelated.

The question for most Zodiac sleuths, is whether any credence can be placed in his Los Angeles Letter of March 13th 1971, of "a hell of a lot more down there". The Zodiac Killer certainly claimed or insinuated many more murders than the canonical five attributed to him, so whether his exploits took him to Poway on May 1st 1967 is wholly dependent on which side of the fence you sit. The timeline bridges the gap between Riverside and Lake Herman Road - and the April 30th 1967 Bates' letters were mailed only one day before the murder of  Nikki Benedict - and did promise "there will be more".

THE CRANK CALL

9/26/2019

 
Benicia Herald: "Bidou and his partner had served a warrant on a Lake Herman Road cabin Dec. 20, 1968, and were on their way to deposit some marijuana in the police department’s evidence locker when they were dispatched back to Lake Herman Road. Initially, they were told a woman was lying outside a car; they thought they were being sent to a crash. Police at first speculated it might have been a crank call, but the officers headed back north. But when they arrived, Bidou realized it was no crank call and no car accident. Instead, it was a sinister crime scene". It is reported that Stella Medeiros was the only eyewitness to see the stricken couple lying on the turnout floor, who then raced off to Benicia and flagged down Captain Daniel Pitta, recorded in the Benicia Police report at 11:25 pm. It was estimated that Stella Medeiros passed the turnout at approximately 11:20 pm. Captain Daniel Pitta would have then radioed into the Benicia Police Department reporting the details and requesting possible assistance. Coming from a experienced officer over the radio, it is difficult to understand how this could be interpreted as a "crank call". A call indicates a telephone call, and not a radio message. This opens up the possibility that somebody other than Captain Daniel Pitta called the Benicia Police Department at around the same time and reported something that was interpreted as an accident on Lake Herman Road. The last reported eyewitness to have passed the turnout prior to Stella Medeiros was James Owen, who was traveling to his graveyard shift at Humble Oil in Benicia.   
Picture
How many times have we passed a certain area and seen somebody lying on the ground and made the assumption that the person has had too many drinks or taken drugs, and just continued on our way, reluctant to get involved. Is it possible that James Owen was driving to work that night and noticed one or both victims lying on the turnout floor and just assumed it was teenagers worse for wear? In other words, his initial reaction was different to that of Stella Medeiros. He continued on to Humble Oil in Benicia and parked up at around 11:18 pm to 11:19 pm. He then entered his place of work, and upon refection, considered that the wise decision was to ring the Benicia Police Department and report that he had seen a "woman lying outside a car" in a turnout. The time of any such phone call would have been very close to 11:25 pm (possibly slightly before) with the unsure nature of the phone call possibly resulting in the police dispatcher considering it a crank call. If a phone call was received by Benicia Police Department reporting a "woman lying outside a car", we only know of one other eyewitness who passed the turnout immediately prior to Stella Medeiros, who could possibly have made this call at around the same time as Captain Daniel Pitta's radio message. That person was James Owen. 
Picture
In an interview with Michael Morford in 2012, he stated "As I was getting ready to leave work the next morning, a worker on the morning shift came in talking about the crime. When I left work, I passed the scene, and there were police there working, so I stopped and told them what I had seen.”

Having now been informed of the gravity of the crime, he did the dutiful thing by informing the police of his recollection of the second vehicle in the turnout, but how would it have been received in light of the double murder, had he now admitted seeing the young girl lying on the turnout floor and just drove on past without seeking the immediate help of police, and making what was described as a "crank call" (possibly lacking urgency). Was James Owen reluctant to admit what he saw in the turnout that night because of his misinterpretation of the crime scene on his way to Humble Oil, and how it may have been viewed by police? Is it possible he saw one or both victims on the turnout floor and didn't make the phone call, making him even more reluctant to reveal the whole truth to police?

In the police report James Owen stated 'that just before he approached the scene, a vehicle passed him going in the opposite direction toward Vallejo. He could give no description of this vehicle. This occurred near the Borges Ranch'. The occupants of this vehicle never came forward - which leaves the possibility that this vehicle could have played some part in the crime. James Owen's gave a second statement on 12.24.68:
"He definitely saw two cars, a station wagon and another vehicle, parked approximately three or four feet to the right of the station wagon. He did not see anyone in the cars or around them. He stated as he traveled approximately one quarter of a mile beyond, he thought he heard a shot."  It is this statement that makes little sense from the standpoint of other eyewitnesses.

The couple were spotted in their vehicle shortly after 11:00 pm by Peggy and Homer Your, but 10 minutes later, according to James Owen, they had completely vanished from the turnout. He didn't mention the doors of either vehicle being open. So, if the Zodiac Killer had driven the young couple from the Rambler, but noticed James Owen approaching the turnout and hidden David Faraday and Betty Lou Jensen out of sight, we would have to assume he closed the door of his vehicle and the Rambler, and then later reopened the passenger side door of the Rambler for some unexplained reason - because this is how it was discovered by responding officers. The actual crime makes much more sense if the couple had already been shot when James Owen approached the turnout and simply misinterpreted what he saw. Had there been a second vehicle present at that time, then James Owen would have passed the turnout with Zodiac still on scene, but possibly out of sight. If there was no second vehicle, then the car traveling toward Vallejo by the Borges Ranch could have been the Zodiac Killer. 

But the bottom line is, that had a phone call been received by Benicia Police Department - described as a "crank call" - then the person who made this phone call had to have passed the turnout very close to the time of Stella Medeiros. If it wasn't James Owen, it may have been the Zodiac Killer himself.   


MARAUDER OR COMMUTER?

9/25/2019

 
A serial killer exhibiting the traits of a marauder will operate using a buffer zone from their residence but radiate from this base when committing their murders, whereas a commuter will operate outside their normal activity spaces, thereby shifting the focus of the investigation away from the offenders anchor point. A serial killer living in Vallejo and operating as a commuter, would in the examples below, travel to San Francisco or Pleasanton to commit their murders and so shift the focus of the investigation away from their home base or residence. Canter and Larkin (1993) proposed the Circle Theory of Environmental Range that suggested a circle drawn around the two furthest offences from each other, would likely reveal the offender's home base, at or near the circle center (as shown by the Zodiac map on the right of the illustration below). This is just a rough example, as the circle could be shifted slightly to the left. Regardless, the center point falls in the approximate area of Vallejo or American Canyon. The problem arises when we draw a circle around a commuter's known offences, in that it would reveal a home location for the killer completely unrelated to his true residence. Therefore, it is critical that we identify whether the Zodiac Killer was a marauder or commuter.
Picture
There have been several studies done that suggest the vast majority of serial killers are marauders, who venture out from their anchor point, with the distance chosen from their residence based upon a buffer zone, the least effort principle, distance decay and a mental map of the area. A serial killer will often commit his earlier crimes closer to home because of uncertainty and inexperience, but venture further afield as their confidence grows. From the perspective of a killer working Monday to Friday, one might expect their Friday crimes to be situated closer to their home location, governed by the least effort principle and time constraints. Whereas their Saturday crimes, free from time constraints and tiredness, would unburden their unwillingness to travel further afield. If the Zodiac Killer lived in Vallejo, then the Canter and Larkin model looks like a good fit. Once the Zodiac Killer had committed his first two attacks close to his residence, the natural inclination on a Saturday would be to shift the emphasis away from the Vallejo and Benicia areas. The third attack at Lake Berryessa swung the focus approximately 42 miles north, while the Presidio Heights murder veered the investigation 35 miles south, into a fourth jurisdiction. It could be argued that the Zodiac Killer was deliberately attempting to redirect investigators away from where he lived. 

Canter and Young noted from a geographical standpoint that a commuter's crimes will generally be grouped closer together, whereas a marauder's crimes will be more spread. If the Zodiac Killer was a commuter living in Vallejo, one could expect him to commit multiple attacks at a secondary location such as San Francisco, in an attempt to focus the investigation far from home. Grouping the attacks within San Francisco would achieve this objective, but spreading the attacks would effectively nullify this tactic. A killer living in Vallejo may attempt to spread his attacks in all directions with each subsequent attack, designed in such a fashion to confuse investigators trying to pinpoint the murderer's anchor point, but may in essence have the reverse effect to the one desired. However, there is one important dichotomy to unpick when we consider the Zodiac Killer compared to most serial murderers - and that is the copious communications he mailed primarily from San Francisco.        
Picture
The Zodiac Killer's attacks spread out as time went by, but apart from his Vallejo Times-Herald communication on July 31st 1969, his focus for letter writing centered squarely on San Francisco. The least effort principle argues that when an offender is presented with two or more options to commit a crime, with equal availability and outcome, they will usually opt for the one that takes the least effort to achieve the same objective. The Zodiac Killer only committed four attacks, but likely mailed in excess of 20 letters. Therefore, is he more likely to go out of his way to deceive investigators by shifting his murders around the map in two or three instances, or mail his letters from an array of different locations to achieve a similar objective? He could have mailed his letters from anywhere, but primarily focused on San Francisco. When you are applying the least effort principle to his letter writing, it is easy to understand why he would choose the path of least resistance. If he had lived in Vallejo and mailed them at various locations on his route to work in San Francisco, then investigators (in his mind) may have been able to piece together his route taken and thereby identify an approximate home location. But by mailing virtually everything in San Francisco it could be interpreted by investigators that he lived in San Francisco - which is something the Zodiac Killer probably realized early on when his communications to the Vallejo Times-Herald went no further.  

His attacks took on the appearance of a marauder, while his letter writing took on the appearance of a commuter - which is exactly what he would have been, had he worked in San Francisco and lived in Vallejo. When your letter writing count outweighs your murder sites five to one, it is far easier to use this in order to focus investigators into a belief that you live in San Francisco, when it requires no more effort than traveling to work each day. The final confirmed murder at Presidio Heights could have been a deliberate choice by a killer determined to divert the investigation down a path far from home, but by reverse psychology, may have achieved the complete opposite to the one intended. 

The Zodiac Killer showed his ability to be unconstrained by a method of operation or modus operandi, with the 'couple killings' more a result of circumstance than choice. Had a third person been present in either vehicle at Lake Herman Road and Blue Rock Springs Park, does anybody believe that the Zodiac Killer would have turned around and gone home? The same could be said for a single person. This was evident when the Zodiac Killer mailed his trinity of letters on July 31st 1969, stating "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". His other two letters made no mention of couples. The idea that this was a sexually frustrated hater of courting couples is not warranted by the limited number of attacks in the sample size, and the idea that he would have just skulked off home, disappointed that he didn't see any couple's making out, is a hard argument to sell. However, the notion of earlier attacks carrying less risk and distance in respect to a home residence, has statistically been proven in previous studies of serial killers, whether or not it is true in this instance.    

THE LOCATION OF THE BOMB [PT3]

9/24/2019

 
In the final instalment of this series we will attempt to refine the previous conclusions gleaned from the Zodiac Killer letters.
The Zodiac Killer stated on April 20th 1970 "I hope you do not think that I was the one who wiped out that blue meannie with a bomb at the cop station. Even though I talked about killing school children with one. It just wouldn't doo to move in on someone else's teritory.  But there is more glory in killing a cop than a cid because a cop can shoot back.  I have killed ten people to date. It would have been a lot more except that my bus bomb was a dud.  I was swamped out by the rain we had a while back." In the correspondence, the Zodiac Killer was referring to the murder of San Francisco police officer Brian McDonnell on February 16th 1970, who suffered devastating and sadly fatal injuries two months earlier, when a bomb packed with fence staples exploded on an outside ledge of Park Police Station in the Upper Haight neighborhood. The wording in the letter suggested that the Upper Haight neighborhood was not somewhere he was prepared to venture, but the suggestion of a school bus bomb and police station, when we take into account the SFPD positioned strategically by the bold, black circle on the Little List crosshairs and indicative of a location point, brings forth the notion of a school bus bomb under the noses of the San Francisco Police Department. Targeting a school bus within sight of a police station would certainly have dealt law enforcement a mighty blow.
Picture
The Zodiac Killer may have had a location in mind, despite the fact it was never followed through on - and this location has tentatively been identified as four radians (+magnetic north) and five inches along the radian in two previous articles. The exact position he had in mind to set up his photoelectric cells to detonate the bomb didn't necessarily have to conform to these measurements exactly, just be close enough to be rounded off by the Zodiac Killer. However, the other clues he gave us in the April 20th 1970 and July 26th 1970 communications were replete with information. We narrowed down a section on Google Maps between Daly City and Ingleside in San Francisco (between 246 and 249 degrees).

To narrow down the location even futher, we should be looking for a bus route approaching a school from north to south (so the sun is rising from the east on the left side). The roadway must have sufficient embankment on its right side to elevate photoelectic switch B. It must be within the parameters of 4 radians and 5 inches (allowing for a small margin of error). The addition of the pronounced black circle within the crosshairs of the Little List Letter in the form of SFPD=0, is suggestive of a location close to a San Francisco Police Department. In other words, the Zodiac Killer may have intended his "blast" right under the noses of law enforcement: "Hey pig doesnt it rile you up to have your noze rubed in your booboos?" Despite not knowing the exact topography of this location in 1970, I have found a site just 230 feet from Ingleside Police Station alongside Southern Freeway.

THE CODE SOLUTIONS BY ZODIAC

9/22/2019

PictureDonald Harden cracking the 408 cipher
The Zodiac Killer mailed us three parts of one cipher on July 31st 1969, to the San Francisco Chronicle, San Francisco Examiner and Vallejo Times-Herald. In his communication to the Chronicle he stated "In this cipher is my idenity". Bearing in mind this is the only portion of cipher with unsolved characters, it could be argued that any identity the Zodiac was offering would be found at the signing off phase in this cipher. It didn't really matter, because only four days later he gave us his identity in the form of "This is the Zodiac Speaking". The Zodiac Killer clearly made a mistake when taking his draught message into his 408 cipher, accidentally omitting the word "people" from the final offering. If we therefore conclude his original identity to be left was actually six characters shorter, it would have reduced the 18 unsolved characters to 12. Using the first-person singular pronoun of "I", his identity at the base of the 408 cipher would read "I am the Zodiac", to become "I am the Zodiac Killer" upon realization of his mistake. The Bay Area murderer literally gave us the exact wording to his unsolved 18 characters through his introductions in the Examiner and Herald letters (both communications began with "I am the killer"). Once we knew the pseudonym or identity as Zodiac on August 4th 1969, the conversion to "I am the Zodiac Killer" was the next logical step. This would become a habit for the Zodiac Killer, who would ultimately give us the exact wording to solve his remaining three ciphers. Not only would he give us the solutions to the codes, but his practice of using 'filler' with no apparent correlation to the solution would continue.  

The Zodiac Killer was no master criminal in the style of Moriarty, but he was nobody's fool either. To make the false assumption he didn't understand ciphers or codes when creating his remaining three offerings to the San Francisco Chronicle, would be a misguided one. Even somebody with limited knowledge of coding, knows that giving us a 32 character code with 29 unique characters within its framework, is practically unsolvable without a key. You can literally fill in the blanks as you choose. Therefore, the only realistic solution to the two smaller codes can come in two forms: [1] The Zodiac Killer can give us a key to decrypt the code, or [2] He can simply give us the answer. The Zodiac Killer may well have chosen option two, and given us the entire solution to all his three unsolved codes in subsequent communications. In fact, the possibilty exists that he supplied us with all the answers in three consecutive communications from July 26th 1970 to October 27th 1970 - in the Little List Letter (07/26/70), 13 Hole Postcard (10/05/70) and Halloween Card (10/27/70). The Zodiac Killer was likely giving us all the solutions before slipping back into anonymity. The newspaper article on November 16th 1970 by Paul Avery, linking Zodiac to the Riverside murder of Cheri Jo Bates on October 30th 1966, likely drew one final breath from the Zodiac Killer through 1971, before his race was run.    

Picture
The "key" phrases for the four codes are *in this cipher is my identity", "the Mt. Diablo code concerns radians and inches",  "Fk, I'm crackproof" and "paradice and slaves". The 408 cipher we have examined, so we will now tackle the 32 symbol code.

The Little List Letter mailed on July 26th 1970, one month after the Mount Diablo code (06/26/70), told us the code "concerns radians and # inches along the radians". It was as simple as adding in two figures to complete the code (hence the hashtag symbol denoting a number). The Zodiac gave us the exact wording for the solution, detailed here in a previous article. As stated above, the 32 symbol code with 29 unique characters couldn't be solved without a key or the answer. The Mount Diablo map and crosshairs were the framework, onto which we "coupled" the code for the location of the bomb. The answer was likely "4 radians and 5 inches along the radian", thereby giving us the solution word for word. An alternative to this solution (where only the hashtag is replaced by the number 5), is "P.S. The Mt. Diablo code concerns Radians and 5 inches along the radians". The Zodiac didn't necessarily have to incorporate the number 4 because we already knew the radian value from the bold, black circle provided on the Little List Letter crosshairs.

Picture
The next solutions may have been given to us in the 13 Hole Postcard - that may ultimately become the most important communication of them all. By combining the "red crucifix" decoder and 13 punch-holes in true "Dick Tracy" style, the Paradice and Slaves formation would be revealed, bisecting the 340 cipher superficially along its mid-section both horizontally and vertically. See the article 'The Dick Tracy 340 Cipher'.  The Zodiac Killer wrote Paradice and Slaves on the Halloween card in the identical formation it could be found on the face of the 340 cipher. Three clues within the space of three weeks.
Picture
The Zodiac Killer also gave us the phrase "Fk, I'm crackproof" (upside down) on the 13 Hole Postcard. Apart from an expletive, the other viable option here, is the Zodiac Killer exclaiming that he is crackproof, preceded by his initials. The reason for this line of thinking, is the Zodiac Killer's wording before the 13 Symbol Cipher on April 20th 1970. The code is designed symmetrically and looks contrived, with three circled 8's fashioned at its center. The Zodiac Killer couldn't have supplied us with his name with any expectation it would be solved, because the code was simply too short and capable of providing us with thousands of solutions. However, he could provide us a solution to the code by giving us his initials. By doing it this way, he is in a roundabout way, giving us his name and a solution to the code that satisfies the introduction that preceded it: "This is the Zodiac speaking. By the way have you cracked the last cipher I sent you. My name is Fk, I'm crackproof".

This solution not only fits into the 13 Symbol Cipher, but reads continuously if imagined in circular fashion. The Zodiac Killer gave us three 8's within a circle (the symbol of infinity, and regeneration and rebirth within Christianity), with the letters K and M positioned ideally in the code to fit "Fk, I'm crackproof" around. There are three elements to this phrase: Fk, I'm, and crackproof. When the entire phrase is slotted around the letters K and M, the number 8 begins each element of the phrase (as shown below).


Picture
The Zodiac Killer had effectively given us the exact wording of "I am the Zodiac Killer", "Paradice and Slaves", "Fk I'm crackproof" and "Radians and (5) inches along the radians" - all of which can be inserted untouched into all four ciphers and provide us with solutions that don't require a key (The "paradice and slaves" solution would only be present on the "canvas" of the 340 cipher, so this would only be a superficial observation). The idea of a killer who constantly responded to the newspapers at every turn, somehow resisting the temptation to ever disclose the workings of his codes and ciphers is a difficult story to sell. If we are of the belief that the 32 and 13 character codes are simply too short and too variable to be solved, then without a key the Zodiac Killer likely supplied an alternative. In the case presented above, the "key" and "answer" could be described as exactly the same thing - and It was just a case of transferring the wording from one communication to another in at least three of the examples.

John Rose used Dave Oranchak's webtoy to create features of the Halloween Card in just an 81 character block around the center of the 340 cipher. Some have stated that the variability of the characters in this area of the cipher have allowed the freedom to manufacture such a result. While that may be the case, a larger pattern of Paradice and Slaves is replicated in a 17 X 17 formation along both same midsections, effectively mirroring the John Rose presentation. The fact that both are even achievable in the same cipher, is worthy of mention. The Bay Area braggart must have been itching to throw us a few clues to his unbroken codes and ciphers - so the notion that he didn't give us any before he disappeared into the twilight - is somehow difficult to swallow.   

THE MURDER CLOCK

9/21/2019

 
Picture
Before the advent of the Rigel software system, utilizing the geographic profiling techniques of criminologist Dr. Kim Rossmo, a rudimentary form of geographic profiling was used by Stuart Kine before the capture of the Yorkshire Ripper, Peter Sutcliffe. This is mentioned by Dr. Kim Rossmo in a 1998 NCIS Conference, stating "I’m sure people in this room are familiar with this case. This is an example of an investigation going awry because of geography. The tape that was sent to the investigators from someone claiming to be the Yorkshire Ripper led to analysis of the accents, they felt there was a Geordie accent, the person was from the Sunderland area, and they focused on that part of England which was about a hundred miles away from where the crimes were occurring. That was wrong. Sutcliffe lived close to the area. Interesting, and I’m not sure how many people are aware of it, but shortly before Sutcliffe’s arrest through work by some patrol officers, a Home Office scientist by the name of Stuart Kine did a sort of basic geographic analysis of the crimes and was quite successful as it turned out in his predictions".  He was in fact very accurate, bearing in mind the size of the killing field - and by literally sticking pins in a map - highlighted an area somewhere by Shipley, only 6 miles from the 6 Garden Lane, Bradford address of Peter Sutcliffe. View geoprofile.

Covered extensively in previous articles, had the Zodiac Killer worked a conventional Monday to Friday, 9 to 5 profession and had lived in the Vallejo area at the time of his murders, we would expect to see his first two Friday attacks relatively close to his home base. Unconstrained by time on Saturday, the Zodiac Killer would be able to venture further afield for his attacks - which is exactly what happened. However, we now have another tool in our arsenal, highlighted in this short but informative video by BCU professor Craig Jackson. Here is a small extract: "Wherever the Yorkshire Ripper was based, the time of his murders would be a vital clue to where he lived. So, if one of the Yorkshire Ripper's victims was murdered in the early evening, 8 o' clock or 9 o' clock at night, that individual could be based very far away from where the Yorkshire Ripper's base was. But if the victim was murdered in the very small hours, midnight, or one or two in the morning, that victim would probably be very close to where the Ripper's base was, assuming that the Ripper would have to be home at a reasonable time to be with their partner or families, or friends who they lived with". The type of victim targeted, the areas they frequented and their availability also has to be factored into the target backcloth. Therefore, we will use the Zodiac Killer's four attacks and see if they conform to a home base in Vallejo.
If the Zodiac had left his house to search for victims on a Friday in the area of Columbus Parkway and Lake Herman Road, then he likely had a knowledge that young courting couples or lone individuals may be found in these remote locations. He has a mental map of the area and an optimal time he would like to return to his residence - but he knows that this sort of victim targeting is unreliable. Sometimes the opportunity may present itself immediately, while other times he may have to do several passes before a suitable target or targets appear. He has to factor this into his thinking when leaving his residence. In other words, if he wants to arrive home no later than 12:15 am, he has to allow for this when leaving his residence. In respect to Lake Herman Road and Blue Rock Springs Park, he could have left his residence at 10:00 pm to allow for this "hit and miss" technique of trawling the eastern edge of Vallejo. This may have accounted for the earlier suspicious sightings on December 20th 1968, prior to the eventual double murder of David Faraday and Betty Lou Jensen.

If we apply the model of professor Craig Jackson to our killer, then an attack at approximately 11:15 pm at Lake Herman Road and midnight at Blue Rock Springs Park, would suggest a killer who lived close by and was aiming to return home sometime in the late evening to early morning hours. If the Zodiac Killer had lived near to the Springs Road and Tuolumne Street payphone, he would have arrived home at around 11:30 pm on 12/20/68, and 12:15 am on 07/04/69. The Zodiac Killer's attack at Presidio Heights would not have been affected by a "hit and miss" targeting technique. Had the murder of taxicab driver Paul Stine been planned ahead of time, he would know where he was to find his victim, where he was going to murder the taxicab driver and where his escape route lay before him - including his journey time back to Vallejo. Paul Stine was murdered shortly before 10:00 pm on 10/11/69. The Zodiac Killer (had he parked his vehicle near the Presidio Park) would have about 5-15 minutes of walk time, followed by a 50 to 60 minute journey home via the Golden Gate Bridge. At the latest, he would arrive home at approximately 11:15 pm. Therefore, his window of time to arrive back at his residence after three of his attacks, would fall within one hour of each other (between 11:15 pm and 12:15am) - although it may be slightly more.     
Picture
The Lake Berrryessa crime is altogether different. If we believe that the Zodiac Killer targeted areas he was familiar with, then he knew that the outskirts of eastern Vallejo, in the secluded areas of Lake Herman Road and Blue Rock Springs during the weekend or holiday season, was likely rich pickings for courting "couples" or "stray people" in the night. The sheer fact he wrote about killing "over a dozen people" at the weekend, showed an element of confidence in these surroundings, despite the obvious braggadocio displayed.

The Presidio Heights area must also have been familiar to him, to risk such an audacious attack in a built-up area of San Francisco. Dr. Kim Rossmo summed it up perfectly:
​​"The San Francisco murder differs significantly from the Zodiac's other crimes. Up to this point he was hunting in locations that had a good probability of containing his desired victims. Target selection was a function of area, not of an individual. However, it is unlikely the Zodiac was successful in all his searches; serial killers typically engage in extensive hunting activities, and for every attack there are many unsuccessful search attempts. In San Francisco, however, the Zodiac controlled the situation through his selection of victim type. The need for such control could be indicative of the distance the Zodiac had to travel to the crime site. Criminals who travel longer distances to offend are less likely to use uncertain target selection techniques".

His familiarity with Lake Berryessa (09/27/69) was also obvious. The Zodiac Killer knew on this occasion that a targeted attack in the late evening hours (close to midnight), similar to Lake Herman Road and Blue Rock Springs Park, was wholly uncertain with respect to finding a suitable victim or victims in this location. But he knew that a late afternoon or early evening attack within the expanse of Lake Berryessa, would be the safest bet, The location, on this occasion, effectively governed the earlier attack time. When this constraint was unburdened during his first, second and fourth attacks (assuming he lived in Vallejo and went directly home), his arrival time to his residence would have always fell within a 60-75 minute window of time. If the Zodiac Killer had a preconceived time he wanted to return home by, then Vallejo by the payphone was a perfect fit for a good night's sleep - as well as not arousing suspicion - had he been married (with children).     


THE LOCATION OF THE BOMB [PT2]

9/17/2019

 
In a previous article we concluded that the 32 character code mailed to the San Francisco Chronicle on June 26th 1970 stated "P.S. The Mt. Diablo code concerns 4 Radians and 5 inches along the radian", based upon the clues the Zodiac Killer gave us in the Little List Letter on July 26th 1970. This led to an area somewhere between Ingleside and Daly City on the south edge of San Francisco. The Zodiac drew us a bus bomb diagram on April 20th 1970, suggesting he was going to place two photoelectric switches on an embankment or hillside on the right side of the road. He stated it was to be set up early in the morning when the sun was rising in the east. The images below show the El Camino Real by Outer Mission, heading south, with the April 20th 1970 'Bus Bomb' diagram superimposed over it. The hillside to the right is the type required to place his two photoelectric switches - one by the roadside and the other higher on the banking. Any school bus heading along this road for early morning assembly, would have the sun rising in the east (shining left to right in the image below).
Picture
If the Zodiac Killer had any intentions of blowing up a school bus (which is unlikely), then he would be targeting the schoolchildren on their way to school in the morning. If the children were being bussed in from other parts of San Francisco for this particular school (St. Thomas More Catholic School), then traveling from the north and east, the bus driver could be using Highway 101 and Interstate 280 in the direction shown by the red line below (recommended on Google maps). The blue circle is 4 radians (+ magnetic north), and 5 inches from Mount Diablo, satisfying the 32 character cipher and Zodiac's statement of "P.S. The Mt. Diablo code concerns Radians + # inches along the radians". The highway under the blue circle is traveling south with the sun to the east in the morning - and is heading toward St. Thomas More Catholic School (just 1.37 miles away).      
Picture
The Zodiac Killer stated on April 20th 1970 "I am mildly cerous as to how much money you have on my head now.  I hope you do not think that I was the one who wiped out that blue meannie with a bomb at the cop station.  Even though I talked about killing school children with one. It just wouldn't doo to move in on someone else's teritory.  But there is more glory in killing a cop than a cid because a cop can shoot back.  I have killed ten people to date. It would have been a lot more except that my bus bomb was a dud.  I was swamped out by the rain we had a while back. The new bomb is set up like this. Sun light in early morning. A + B are photoelectric swiches when sun beam is broken A closes circut. B opens circut, which makes B the cloudy day disconect so the bomb won't go off by accid. PS I hope you have fun trying to figgure out who I killed".

​​The choice of words the Zodiac used at the beginning of this communication were unfortunate, had his target been children from St. 
Thomas More Catholic School. The school was named after Thomas More, an English lawyer, social philosopher, author, statesman, and noted Renaissance humanist. He was also a Chancellor to Henry VIII, and Lord High Chancellor of England from October 1529 to 16 May 1532. He was sentenced under the Treasons Act 1534 and decapitated with an axe. Therefore, it was very unfortunate that the Zodiac Killer should state "I am mildly cerous as to how much money you have on my head now".

There are several other schools in this area between Ingleside and Daly City, but we must remember that it is the bus he was targeting, not the school. Therefore, we should prioritize the roadways in this area (shown by the red rectangle), from the perspective of a bus traveling south, with its left side facing east.

A TAHOE MYSTERY

9/16/2019

 
In two previous articles we analyzed the design of the Pines Card in association with the disappearance and likely murder of Donna Lass on September 6th 1970. There are multiple possibilities, notably [1] The Pines Card contained nothing of value [2] The punch-hole fell over the Donner Memorial State Park, hinting at the young woman's name in similar fashion to the Monticello Card four months later, but had no directions to her burial site [3] The Pines Card contained clues to her name and burial site [4] The Pines Card contained directions to something Zodiac placed for investigators or the public to find, thereby (if found) bolstering the notion he was involved in her disappearance and murder. This could have been placed at a predetermined location prior to the mailing of the Pines Card. Or the most likely, [5] The Zodiac Killer crafted the Pines Card, but had absolutely nothing to do with her demise. This is the route we shall take in the following examination. 
Picture
I have come to the inescapable conclusion that the Zodiac Killer had nothing to do with the disappearance of Donna Lass from the Sahara Tahoe Hotel & Casino on September 6th 1970, and his willingness to suggest such an involvement was prescribed by the writings of the San Francisco Chronicle. On September 26th 1970, the disappearance of Donna Lass was extensively covered in a San Francisco Chronicle newspaper article entitled Nurse Vanishes -- A Tahoe Mystery. This must have been a goldmine for the Zodiac Killer, with all the ingredients contained in the article a compelling blend of circumstantial evidence just waiting to be picked. The Zodiac Killer knew that the circumstances surrounding the young woman's move from San Francisco to South Lake Tahoe was the perfect cocktail to convince investigators he was a viable candidate in her murder. The added benefit for the Bay Area killer was the suggestion of a link to the murder of another nurse, Judith Hakari, abducted on March 7th 1970, and later discovered in a shallow grave in Weimar. The Zodiac Killer could effectively link himself to two murders for the price of one. 

Many murders passed through the pages of the Chronicle newspaper, but this story had everything the killer required. Of course, he must have realized by now, that if he had mailed a communication immediately after the newspaper article, stating an involvement in her disappearance, then it would appear all too convenient, with his writings likely dismissed as a killer just latching on to the latest crime story. But by waiting months, as he had done with Kathleen Johns, his claims (in his mind) may carry more weight with investigators. In other words, the publicity had died down regarding the disappearance of Donna Lass, yet he still had the crime in the forefront of his mind even after six months, thereby adding validity to such a claim. 

Rubislaw32, a contributor to this site, touched on the idea that the March 22nd 1971 Pines Card may have been influenced by the abduction and murder of Judith Hakari. This idea carries much weight, when we consider the inspiration for the Pines Card was likely generated from the September 26th 1970 newspaper article six months earlier. The article was rich pickings for a killer who had previously murdered taxicab driver Paul Stine in the Presidio Heights area of San Francisco, so close to the Letterman General Hospital where Donna Lass had previously worked. The disappearance of a woman 150 miles from San Francisco, who had recent connections to San Francisco in the Presidio Heights district, must have been more than the Zodiac Killer could have wished for. Many disappearances and murders had occurred much closer to the Bay Area than the Lake Tahoe Mystery, but this one was covered comprehensively by the Chronicle and had the details the Zodiac Killer couldn't have failed to notice. We look for overlapping features in the Presidio Heights murder of Paul Stine by Zodiac, with the movements of Donna Lass and her eventual abduction from South Lake Tahoe, noting the location of the Letterman General Hospital with respect to the Presidio Park the killer escaped into. We then take the Pines Card depicting Incline Village and draw parallels to the crimes based on their locations, thereby concluding a possible Zodiac involvement in both. The problem being with this line of thinking, is the Zodiac Killer knew that these conclusions would be drawn when he created the Pines Card - because he had read the San Francisco Chronicle newspaper article and noted these comparisons himself. The Zodiac Killer was effectively forcing you into making an unwarranted connection, thereby bolstering a case for his involvement in the Donna Lass case. Everything required for the Pines Card sat in the September 26th 1970 pubication.          

Picture
All the Zodiac Killer required was a map of Lake Tahoe and the above newspaper article to create the perfect ruse. He had noted that a connection was being considered between the cases of Donna Lass and Judith Hakari, with the Sutter Hospital nurse having been discovered "buried in a shallow grave in the Sierra foothills of Placer County". Therefore, to give credence to his claims in the murder of Donna Lass (and possibly Judith Hakari), what better way than to place the pasted phrase of "around in the snow" upside down, to give the impression Donna Lass is buried in a shallow grave, and thereby tying the two cases together in modus operandi. Then place the pasted location of "Sierra Club" on the Pines Card to subconsciously plant the seed of a link to the "Sierra" of "the Sierra foothills of Placer County", where Judith Hakari's remains were subsequently unearthed. 

The newspaper article told us that Donna Lass worked at the Sahara Tahoe Hotel on the south side of the lake, so even a modicum of investigation to discover the location of the local police department, would allow the Zodiac Killer to direct the investigators "past the Lake Tahoe areas" to the the pine-laden wilderness and a likely burial site. Then came the pièce de résistance in the Pines Card, further forging a link between the Zodiac Killer, Donna Lass and San Francisco. The Zodiac Killer wanted investigators to draw the conclusion he had previously targeted Donna Lass in the Presidio area of San Francisco, and so driving them to the conclusion that he had traveled to South Lake Tahoe to complete his mission of killing the young woman Unfortunately, the Zodiac Killer may have overestimated the ability of police to discover the true meaning of "sought victim 12".
PictureClick image to enlarge
By using the past tense of seek in "sought", the Zodiac Killer was attempting to convince investigators he had previously trailed Donna Lass as victim number 12. The newspaper article gave us all the movements of Donna Lass, stating "Miss Lass became a first-aid nurse at the Sahara last June, living the previous five months in San Francisco and working at the Letterman General Hospital at the Presidio". The Zodiac Killer therefore knew that Donna Lass was in San Francisco in the January of 1970. He was only claiming 10 victims by April 20th 1970, and 12 victims by June 26th 1970, so it wasn't difficult for the Zodiac Killer to work out, that he could have "sought her as victim 12" before she left for South Lake Tahoe in June. The Zodiac Killer would have been seeking Donna Lass as victim number 12 sometime between April 20th 1970 and when she began her new job in June. By using the past participle of "seek", the Zodiac Killer was attempting to convince investigators his interest in Donna Lass had begun long before her disappearance - and in doing so, hopefully reinforcing a connection between San Francisco and South Lake Tahoe, with him as the common denominator between the two.

On March 19th 1971, the San Francisco ran an advertisement for condominiums at Incline Village by Lake Tahoe. The Zodiac Killer, having now waited the necessary time to authenticate his claim in the disappearance and murder of Donna Lass, lay the final piece of the jigsaw. His ruse was now complete.    

"SAM" THE KILLER

9/15/2019

 
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".
Picture
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. 

THE LOCATION OF THE BOMB?

9/13/2019

 
The Zodiac Killer mailed a bomb threat on June 26th 1970, stating "the map coupled with this code will tell you where the bomb is set." One month later, realizing the inadequate information he had provided, the Zodiac Killer mailed another communication stating "P.S. The Mt. Diablo code concerns Radians + # inches along the radians", while adding some crosshairs with a black circle and the addition of SFPD = 0 alongside it. The overwhelming majority of the Zodiac Killer's communications were mailed to the San Francisco Chronicle and his taunting of the police heavily focused on the San Francisco Police Department from 1969 to 1971. If a bomb was to be set, then the Zodiac Killer was likely targeting San Francisco. He almost certainly never followed through on any of these threats, but it would be interesting to discover where his intended focus was, and find the solution to the 32 character code supplied on June 26th 1970. This topic has been covered before, but this will iron out a few problems experienced with previous articles.

The Zodiac Killer couldn't resist responding to the newspapers when he was asked to supply more details about his crimes, as demonstrated when he delivered the August 4th 1969 'Debut of Zodiac' Letter. He responded in a seven-page letter to refute the claims of Captain Martin Lee of the San Francisco Police Department, when his October 13th 1969 letter was disbelieved. He also wasn't averse to claiming various murders, disappearances and abductions that had featured in the newspapers. Despite this, the overwhelming consensus exists of a killer who remained resolutely silent on the workings of his three unsolved cryptograms or codes. However, there is every chance he gave us the exact wording that permeated the 340 cipher, to which he fashioned into the Halloween Card one year later. This was explored in the article Zodiac Admitted 340 Not a Real Cipher. I also believe he gave us the exact wording in the July 26th 1970 'Little List' Letter to solve the 32 character cipher a month earlier.

Picture
A radian value is approximately 57.3 degrees, which travel counter-clockwise. However, the Zodiac Killer placed a form of numerical clock face around the circumference of his crosshairs on the Mount Diablo map and stated that it be set to Magnetic North (about 17 degrees in 1970) - so it was considered that he had formulated his radians to run clockwise. The only radian value that can fall near San Francisco when a line is subtended from Mount Diablo, is 4 radians + 17 degrees = 246.2 degrees. Three and five radians doesn't fall anywhere near San Francisco. Therefore, a bomb set in San Francisco would have to be around the 4 radian + Magnetic North value. The bold, black circle present on the 'Little List' Letter crosshairs, falls in the region of 246.2 degrees - bearing in mind it is just a rudimentary sketch. Shown on the map above, is 2 radians counter-clockwise from True North (which would land at 245.4 degrees clockwise from True North). Both examples landing in the same region of the map. Daly City Police Department sits around 246 degrees from Mount Diablo, but resides in San Mateo County (shown by the red line). Ingleside Police Station (shown by the green line) sits closer to 249/250 degrees, but resides in San Francisco. If the Zodiac Killer had chosen a target in this region, we might expect the radian value to be only a rough guide. But it is clear, that if he is referring to a radian value, then it has to be a whole number - and it can only be 4 radians. 

Likewise, the value of inches can only be 5, if we are referring to a bomb threat in San Francisco. The scale on the Mount Diablo map is 6.4 miles to the inch. Four and six inches (25.60 and 38.40 miles) both fall into the sea on the east and west coast of San Francisco. So, unless the Zodiac Killer was wearing scuba gear and was planning to blow up an underwater school bus, the value of inches had to be the whole number of 5. When 5 inches is subtended from Mount Diablo, it gives us a value of 32 miles (somewhere in the red box below, allowing for a small margin of error). This margin of error has also been applied vertically to encompass Ingleside Police Station, bearing in mind that SFPD = 0 threat. Whether the mention of SFPD in the crosshairs on the 'Little List' Letter implies a specific threat to San Francisco itself, or somewhere close to San Francisco is unknown - but the region of San Francisco seemed the primary focus of the Zodiac Killer's communicaions during this two-year period. 
Picture
Now that we know a threat in the San Francisco region has to be subtended using the whole numbers of 4 radians and 5 inches, let us use the Zodiac's own words to complete the 32 character cipher, just like the words Paradice and Slaves from the Halloween Card was used to fill in the 340 cipher. The Zodiac Killer wrote on July 26th 1970: "P.S. The Mt. Diablo code concerns Radians + # inches along the radians". But notice the hashtag.

The symbol # is most commonly known as the number sign, The symbol is described as the "number" character in an 1853 treatise on bookkeeping, and its double meaning is described in a bookkeeping text from 1880. The instruction manual of the Blickensderfer model 5 typewriter (c. 1896) appears to refer to the symbol as the "number mark". Some early-20th-century U.S. sources refer to it as the "number sign", although this could also refer to the numero sign. A 1917 manual distinguishes between two uses of the sign: "number (written before a figure)"; and "pounds (written after a figure)". Mainstream use in the United States is as follows: when it prefixes a number, it is read as "number", as in "a #2 pencil" (indicating "a number-two pencil"). The one exception is with the # key on a phone, which is always referred to as the "pound key" or "pound". Thus instructions to dial an extension such as #77 are always read as "pound seven seven". Wikipedia.

The Zodiac Killer could easily have left the phrase as "P.S. The Mt. Diablo code concerns Radians + inches along the radians", but deliberately forced the hashtag into place to denote a number - that number being 5. The phrase would now read "P.S. The Mt. Diablo code concerns Radians + 5 inches along the radians". We know that any threat on San Francisco had to fall in the 4 radians value, so we can complete the phrase: "P.S. The Mt. Diablo code concerns 4 Radians + 5 inches along the radians". But because we have now added a specific "5 inches" to be subtended along the line of the 4th radian, the correct phrase would read "P.S. The Mt. Diablo code concerns 4 Radians + 5 inches along the radian".
An alternative to this solution (where only the hashtag is replaced by the number 5), is "P.S. The Mt. Diablo code concerns Radians + 5 inches along the radians". The Zodiac didn't necessarily have to incorporate the number 4 because we already knew the radian value from the bold, black circle provided on the Little List Letter crosshairs.

There is no way this code could realistically be solved with 29 unique characters and no key. But fortunately the Zodiac Killer realized this and gave us the answer one month later. He did the same with Paradice and Slaves in the Halloween Card, to help our understanding of the 340 cipher. So, where is the answer to the '13 Symbol' cipher mailed on April 20th 1970?

THE ANTI-CAPITALIST AGENDA

9/10/2019

 
The disdain for "yellow journalism", capitalism, multi-media conglomerates and the Hearst Corporation in particular, was clearly evident in the actions and writings of the Symbionese Liberation Army from 1973 through to 1975. Their communications were diverse and many during this period - with the group becoming the focus of attention when they kidnapped media heiress, Patricia Campbell Hearst on February 4th 1974. The Zodiac Killer was attributed with four communications between January 29th 1974 (Exorcist Letter) and July 8th 1974 (Red Phantom Letter), however, doubt has been cast on at least three of these four communications - in particular, the SLA Letter mailed from Los Angeles on February 3rd 1974. Here is a brief summary regarding the SLA Letter and its possible links to the Exorcist Letter. The following will examine the notion of the Exorcist Letter having been mailed by the Symbionese Liberation Army as a form of veiled attack on the film industry and its control of the populace through mass indoctrination. This became further evident when the Badlands Letter arrived at the San Francisco Chronicle on May 8th 1974, expressing consternation at the running of advertisements for the Badlands movie, directed by Terrence Malick and starring Martin Sheen and Sissy Spacek. But first, here is an example of the Symbionese Liberation Army threatening to "Seize CBS" (Columbia Broadcasting System) in a communication addressed to Paul Greenberg on February 19th 1974. CBS (an initialism of the network's former name, the Columbia Broadcasting System) is an American English language commercial broadcast television and radio network that is a flagship property of CBS Corporation. The company is headquartered at the CBS Building in New York City with major production facilities and operations in New York City (at the CBS Broadcast Center) and Los Angeles (at CBS Television City and the CBS Studio Center).

William Samuel Paley (September 28, 1901 – October 26, 1990) was the chief executive who built the Columbia Broadcasting System (CBS) from a small radio network into one of the foremost radio and television network operations in the United States. William Paley met Dorothy Hart Hearst (1908–1998) while she was married to John Randolph Hearst, the third son of William Randolph Hearst. Paley fell in love with her, and, after her Las Vegas divorce from Hearst, she and Paley married on May 12, 1932, in Kingman, Arizona. This may have been one of a number of reasons why the Symbionese Liberation Army targeted this network, not withstanding the headline on the front page. Much of the Symbionese Liberation Army's communications and tape recordings were mailed to the newspapers and radio stations, often exhibiting a hatred of "big business" and global capitalism. This may have included the film industry as well, and hence the ridicule of The Exorcist movie which was attracting huge audiences and vast media coverage before and after its release. The author of the Exorcist Letter (possibly the Symbionese Liberation Army), were clearly rattled by the wallowing masses bewitched by this film, describing it as "the best satirical comedy that I have ever seen". Who were subsequently irked by the coverage of the Badlands movie also.
PictureClint Eastwood in Dirty Harry
The Symbionese Liberation Army held headquarters in San Francisco and Los Angeles, the latter of which ties both The Exorcist and Badlands movies together under the banner of Burbank, California. The Exorcist and Badlands films were both distributed by Warner Brothers. Warner Bros. Entertainment Inc. is an American entertainment company headquartered in Burbank, California and a flagship subsidiary of AT&T's WarnerMedia. Founded in 1923. It has operations in film, television and video games and is one of the "Big Five" major American film studios, as well as a member of the Motion Picture Association of America. The "Big Five" are the five major players in the film industry that included Columbia Pictures, who in 1972 went into partnership with Warner Bros.to form the Burbank Studios in the heart of SLA country. Was this a secondary motive for the Symbionese Liberation Army (if responsible), highlighting The Exorcist and Badlands movies because they were both the product of Warner Bros. in Los Angeles? The January 29th 1974 Exorcist Letter featured Tit-Willow from Gilbert & Sullivan's The Mikado. The 1967 British film adaptation, directed by Stuart Burge, was also distributed by Warner Brothers, as ironically, was the Dirty Harry film starring Clint Eastwood, that passed Zodiac by.

The disdain would continue with the Red Phantom Letter, mailed on July 8th 1974 to the San Francisco Chronicle, when Count Marco was told to go back to the "hell-hole from whence it came". The letter was again demanding the removal of elements featured in the newspaper. The appearance of sensationalized material, "yellow journalism" and the coverage of challenging material such as The Exorcist and Badlands movies through adverisements - and likely swaying the masses - seemed only to engender the mocking derision in the author of the 1974 communications. The overblown and dramatic coverage of The Exorcist film, featured in the San Francisco Chronicle on January 11th 1974 under the title of Weird Goings on at the Movies, appeared the driver behind the January 29th 1974 letter. But was that driver the Symbionese Liberation Army or the Zodiac Killer?

WHERE IS DONNA LASS? [PART 2]

9/8/2019

 
Here we will take a further look at the disappearance of Donna Lass from the Sahara Tahoe Hotel & Casino on September 6th 1970, attempting to discover the approximate area she was disposed of or buried. The last article on this subject pinpointed an area along California State Route 89 by Pole Creek Trailhead. The Zodiac Killer (if responsible for her murder) had previously made two phone calls to police, directing them to the crime scenes at Blue Rock Springs Park and Lake Berryessa. When the Pines Card was mailed on March 22nd 1971 it held directions within its design, such as "Sierra Club", "pass Lake Tahoe areas" and a punch-hole on the right side. The postcard was mailed to the San Francisco Chronicle and was addressing the police.

Here is a snippet from the South Lake Tahoe Police Department website: "The South Lake Tahoe Police Department (SLTPD) was formed July 1, 1967. The first home of the department was on the southwest corner of Lake Tahoe Boulevard at “D” Street. This is currently the present location of the City Corp. Yard. By the spring of 1969, SLTPD had 33 officers, seven civilian positions, and nine vehicles. We needed a bigger facility. So during the tenure of John Crow, the second Chief of Police at the helm of SLTPD, the Police Department moved to a month-to-month rental facility at Fremont Avenue and Mono Way. This structure is now the home of Nel’s Hardware store. This building was not constructed as a police facility, and eventually another move was needed. In April of 1973, the department moved to its current location in the El Dorado County Government Center, on Johnson Boulevard".
All three of these locations sit under the south side of the lake, so the instructions on the Pines Card to "pass Lake Tahoe areas" can only mean one of two things - the police needed to travel along the east side of the lake using US Route 50, towards Incline Village (the area depicted on the Pines Card), or travel along the west side of the lake, towards the Donner Memorial State Park and the Sierra Club at Clair Tappaan Lodge (also depicted on the Pines Card). See below. 

Picture
If the killer was living or vacationing on the south side of the lake, then he may very well have crossed paths with his target at the Sahara Tahoe Hotel & Casino, the Monte Verdi Apartments at 3893 Pioneer Trail (where Donna Lass lived), or somewhere close by. Whether he murdered Donna Lass first, then disposed of her body, or murdered her at the location he concealed her body, his most direct and convenient route of travel from the south side of the lake, is to "pass the Lake Tahoe areas" on the east or west side, via a major route. California State Route 89 and US Route 50 both skirt the lake on either side, and more importantly, head towards Incline Village and the Sierra Club at Clair Tappaan Lodge.

A newspaper article stated that 'the site depicted on the 'Pines Card' was from an advertisement published last Sunday by several newspapers. It was an artist's rendition of houses among the trees at a Boise Cascade Company project at Incline Village, where construction has just begun on the development. While much of the Sierra area is under several feet of snow, Incline Village has only two feet on the ground. Police went to the area to determine if a search is possible'. ​Chief Lauritzen added "There's no point to a search at this time. It's unlikely a victim would be uncovered before spring". This indicates that a search was to be initiated in this area, but it clearly failed to unearth the remains of Donna Lass. Parking your vehicle in the area of Incline Village under construction doesn't seem the most sensible choice to start digging a grave. When we consider that the July 13th 1971 Monticello Card revealed the name "Kathy" at the Oak Hill Memorial Park, and the Pines Card overlayed over the Sierra Club of Clair Tappaan Lodge revealed the name "Donna" (at the Donner Memorial State Park), it seems as though the Incline Village advertisement was used more as a template, rather than the actual burial site. The act of the Zodiac Killer adding "Sierra Club" to the postcard was clearly significant in this instance.  

Using a sprinkling of geographic profiling and the words on the Pines Card, the Zodiac Killer would be "past the Lake Tahoe areas" at Tahoe City, where California State Route 89 breaks away from the lake. He now has to effectively bury Donna Lass between Tahoe City and the Donner Memorial State Park by Truckee. Is he going to risk performing this task by Alpine Meadows or Olympic Valley?, or travel to the much more secluded area by Pole Creek Trailhead, which is exactly mid-distance between Tahoe City and the Donner Memorial State Park - this is the first and logical choice to avoid detection. There are some other turn off areas in this region of California State Route 89 where the Zodiac Killer could have disposed of a body, but mid-distance in a secluded area and sitting under his crosshairs on the Pines Card overlay, seems as good as any.

X MARKS THE SPOT

9/7/2019

 
Picture
The Zodiac Killer mailed the Bus Bomb Letter on November 9th 1969, opening with the lines "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". Then on page 6 he gives us the Zodiac crosshairs with five X's marked on the circumference, accompanied by "PS. Be sure to print the part I marked out on page 3 or I shall do my thing". These X's are meant to be the areas he is threatening to target if his demands are not followed. The crosshairs can be spun around and placed over a map to correlate with the attacks at Lake Herman Road, Blue Rock Springs, Lake Berrryessa and Presidio Heights, like so. But this only accounts for four attacks and five murders, when clearly the Zodiac Killer is claiming five attacks and seven murders at this juncture. The additional attack he was claiming, was the August 3rd 1969 double stabbing of Kathy Snoozy and Deborah Furlong in San Jose, to which he added "Aug" on the November 8th 1969 'Dripping Pen' card. Furthermore, the inaccuracy of attempting to transfer the crosshairs from the Bus Bomb Letter, to overlay onto a map, is extremely problematic. The Zodiac Killer had placed very small dots around the crosshairs to represent the numbers on a clock face. Therefore, to be far more accurate, we need to place the perfect circle of a clock face over a map and locate the five X's he has placed around the circumference.

One thing to remember here, is that many people have centered these crosshairs over Mount Diablo, when by November 9th 1969 the Zodiac Killer had never referenced Mount Diablo in any of his communications. We would have to wait until June 26th 1970 for the Zodiac Killer to send us the Phillips 66 Road Map with his crosshairs centered over Mount Diablo. These crosshairs had the numbers 3, 6 and 9 around its face, also suggestive of a clock face. So, although the Bus Bomb Letter crosshairs came with no indication of where they (or a clock face) should be placed, it is apparent in hindsight they were to be placed over Mount Diablo. There is also no indication in the Bus Bomb Letter that we should try in any way to rotate the five X's around to suit our needs. Below, I have placed a clock face over Mount Diablo to locate the positions 6, 8, 9, 10 and 11, marked out by the Zodiac Killer         

Picture
Interestingly, the Zodiac Killer was claiming five attacks by November 9th 1969, and positions 1 to 5 are vacant on the clock face. The first X falls over position 6, which heads off towards San Jose, the site of the murders he was claiming just one day earlier. Position 10 on the clock face passes directly over Rodeo, the location where Leona LaRell Roberts was to be abducted from in one month from now, on December 10th 1969 (the date matching the clock face). Position 11 passes directly over Pacific Union College in Angwin - the college significant to the attack at Lake Berryessa on September 27th 1969. Position 8 passes over Oakland, brought into play, when on June 18th 1970 a letter was mailed from somebody claiming to be the Zodiac Killer, enclosing two Oakland A's tickets for Gerald Tagert. Position 9 passes directly over Tamalpais Valley, Isobel Watson (33) had just got off the bus on the evening of April 7th 1972, and was walking home along Pine Hill Road, Tamalpais Valley, Marin County at 9.00 pm, when a light colored vehicle veered towards her, knocking her to the ground. The driver exited his vehicle offering to take her home, but after she had refused his offer of apparent help a second time, the concerned citizen suddenly became enraged, pulling out a knife and stabbing the woman in the neck and shoulder. ​Her screams alerted the neighborhood, forcing the assailant into a hasty retreat from the scene. She was treated at Marin General Hospital and fortunately survived the brutal attack.

I don't know whether these examples highlighted were the intention behind the five X's on the circumference, but it can be strongly argued, based on the Zodiac Killer's introduction in the Bus Bomb Letter, that he was threatening more attacks without announcing the murders he was to accomplish. The statement next to the crosshairs of
"PS. Be sure to print the part I marked out on page 3 or I shall do my thing", suggests that these five X's would be the result of non-compliance, rather than the attacks he had already carried out. The Zodiac is split into 12 signs just like a clock face - beginning at zero degrees longitude - which is maybe why the Zodiac Killer attributed zero to the north face of his crosshairs on the June 26th 1970 Phillips Map. Had the Zodiac Killer originally intended to commit 12 attacks when he began his murderous campaign of terror, thereby completing the circle he had created for himself? Something to which he would later realize was simply unachievable.
