TWO DEATHS AND ONE ATTACK NEAR SHORELINE HIGHWAY

1/17/2021

 
Picture
A man was seen running into Julius Khan playground shortly after the murder of Paul Stine on October 11th 1969, detailed by author Robert Graysmith, who stated "The detectives heard from neighbors that a stocky figure was seen dashing across Julius Khan playground and into the dense undergrowth of the Presidio. The dog patrol units, seven of the best search dogs in the country, gathered at the front entrance of the Presidio and were deployed one at a time in various directions. Armstrong and Toschi considered the possibilities. Had the killer gone quickly through the dark woods and emerged from the Presidio at Richardson Avenue, and taken Highway 101 past Fort Point onto the Golden Gate Bridge and vanished into Marin County".

It was speculated that had the Zodiac Killer exited the Presidio Park on its eastern edge to a waiting vehicle, with his escape via the Golden Gate Bridge into Marin County a matter of minutes away, providing separation from the San Francisco area. If the Zodiac Killer worked in San Francisco (near Presidio Heights), but commuted from Vallejo, then he may have used Highway 101 on a regular basis, passing through Marin County. Highway 101 straddles Shoreline Highway by just 724 meters, which we will return to shortly.

Here is an excerpt from Websleuths by Steph54 "On 28 December 1969, a man searching for driftwood on the beach at Bolinas Lagoon in Marin County found the nude body of Leona Roberts. It was later determined that a unique wristwatch was missing from the girl's wrist, but a Napa High School class ring given to her by a neighbor still remained on her finger. The tan dress she wore when last seen, along with two pairs of bell-bottomed pants, a blouse, a black purse and wallet, a key chain with car and house keys were also reported missing. There were marks on the wrists and ankles indicative of binding, but the coroner was unsure whether they occurred before or after death. The cause of death was reported as "due to viral infection of an unidentified species." It was also reported that there was "evidence of choking which could probably be linked to the virus." link.

Leona LaRell Roberts had been abducted on December 10th 1969 from 749 Tormey Avenue in Rodeo. At about 5:50 pm a neighbor, Susan Clark, heard the sound of a girl screaming, followed by somebody running from the rear of the apartment. A suspicious male was observed many times between the front door and a blue station wagon, before he eventually drove away. The man was described as 25 years old, 5'8", short blond hair and wearing brown trousers and a jacket. A while later her boyfriend arrived home to find a disturbance inside the apartment, scuff marks near the back door and her red Volkswagen parked outside.

The same day, a potential Zodiac correspondence arrived at the Sacramento Bee newspaper containing a horoscope page with pasted wording. This communication entitled Day-By-Day Forecast For Cancer was pasted with the wording ZODIAC, WATCH, FLT 555 and BIRDS FLY SOUTH. The day after the Leona LaRell Roberts abduction, on December 11th 1969, a communication entitled Day-By-Day Forecast For Leo arrived at the San Francisco Newspaper Printing Company at Rincon Annex, again  with many pasted words, including FLT THREE OF A KIND. It was thought that the Day-By-Day Forecast For Leo may have been a sinister play on words for Day-By-Day Forecast For Leona Roberts, considering the date of her abduction and the mailing of this communication the following day.

A day-by-day forecast may have been an appropriate message considering her abduction on December 10th 1969, to the eventual discovery of her body eighteen days later at Bolinas Lagoon in Marin County. This is where Shoreline Highway comes into play, being just 724 meters from Highway 101, and a route that the Zodiac Killer may have commuted to and from work. Shoreline Highway runs alongside Bolinas Bay to Bolinas Lagoon, where Leona Robert's body was discovered. When we consider the December 10th 1969 communication containing the words ZODIAC and BIRDS FLY SOUTH, coupled with the December 11th 1969 Day-By-Day Forecast For Leo and her body being discovered at Bolinas Lagoon, the following information may become relevant.

Bolinas Lagoon is a tidal estuary, approximately 1,100 acres in area, located in the West Marin region of Marin County, California, United States, adjacent to the town of Bolinas. The Pacific Flyway is a major north-south flyway for migratory birds in America, extending from Alaska to Patagonia. Every year, migratory birds travel some or all of this distance both in spring and in fall, following food sources, heading to breeding grounds, or travelling to overwintering sites. Along the Pacific Flyway, there are many key rest stops where birds of many species gather, sometimes in the millions, to feed and regain their strength before continuing. Some species may remain in these rest stops for the entire season, but most stay a few days before moving on. Wikipedia.

Four months later, on April 19th 1970, Pat Tan, a woman of Eurasian descent, was discovered hanging by rope and electrical cord from an oak tree near Bootjack Campground on Mount Tamalpais in Marin County. She was identified because of a key found in her pocket by Coroner, Keith Craig, which he traced to a Greyhound bus terminal and the eventual discovery of her address book. The question remains as to whether the death of Pat Tan was suicide or murder.

Bootjack Campground is located 553 meters from the Pantoll Campground along Panoramic Highway, which joins Shoreline Highway at its southern tip, Pat Tan's body was discovered hanging just 2.5 miles from the dump site of Leona Roberts at Bolinas Lagoon. Leona Roberts abduction was paralleled by two communications entitled Day-By-Day Forecast For Cancer and Day-By-Day Forecast For Leo, along with the pasted pseudonym of ZODIAC, as was the untimely death of Pat Tan, when the following day on the April 20th 1970, the Zodiac Killer mailed the 13-Symbol cipher containing THREE OF A KIND. However, this time it would be 888 instead of 555.

Two years later, on April 7th 1972, 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.

Her description of the man alerted investigators to a possible Zodiac connection, that of a man with heavy-rimmed black glasses, around 40 years of age, 5' 9" in height and short brown hair. It was not overlooked by police that the killer had attempted to lure the woman into his vehicle, not dissimilar to the method employed in the Modesto abduction of Kathleen Johns. Napa County homicide detective Kenneth Narlow believed in a greater than 50-50 chance of a Zodiac connection, bearing in mind the description given by Isobel Watson. Pine Hill Road, where the attack occurred, joins Shoreline Highway at its southern edge, just 4 miles from the Bootjack Campground and 7 miles from Bolinas Lagoon. Shoreline Highway joins Panoramic Highway only 1 mile from Pine Hill Road. So, had the attacker of Isobel Watson managed to lure her into his vehicle, would we have found her near Bootjack Campground or Bolinas Lagoon, just like Pat Tan and Leona Roberts? Of course, we don't know whether the Zodiac Killer had anything to do with the unfortunate events that befell these three women, but the location of Marin County and the proximity of Pine Hill Road, Bootjack Campground and Bolinas Lagoon is worthy of further investigation.

"PUZZLES IS ONE OF MY PLEASURES"

1/4/2021

 
The Concerned Citizen card was mailed from San Francisco and postmarked August 10th 1969, arriving one day after the article A Murder Code is Broken which featured in the San Francisco Chronicle newspaper. In this article "Vallejo Police Sergeant John Lynch, in charge of the investigation of the murders and of the cipher letter writer, asked The Chronicle to send Harden's code breaking worksheets to him for further checking; which was done". The Concerned Citizen communication (with attached 408 cipher key) was not mailed by Donald Harden, having been sent from either a genuinely helpful citizen or from the Zodiac Killer himself. When deciding which is the case, we can look at the typed message on the card (shown below).

For somebody who pleasures in the solving of cryptograms and word puzzles, while at the same time making basic spelling mistakes and errors in punctuation, seems rather reminiscent of somebody we have become accustomed to. Three months after this correspondence, the Zodiac Killer mailed the infamous 340 cipher, a curious blend of both word puzzle and cryptogram. This cipher had "paradice" and "slaves" criss-crossed on its canvas, with a full message beneath the superficial design. The canvas and cipher both contained the encoded words of "paradice" and "slaves", thereby continuing the theme from the 408 cipher, but on this occasion he seemed eager to add a little more complexity to its design.

The decoding of the 340 cipher revealed that the majority of the message effectively ran diagonally (one down, two across) in a cipher divided up into three parts of 9, 9 and 2 rows. The last two rows were composed of a curious blend of forward and backward words, which is standard fare in the construction of word search puzzles, as is the creation of diagonal wording running across a word search grid. When we couple this with the disguised "paradice" and "slaves" running down and across the center of the 340 cipher canvas, this cryptogram becomes the embodiment of cipher and word puzzle all rolled into one.

If that wasn't enough, the Zodiac Killer would mail two more communications on December 10th 1969 and December 11th 1969 with coherent messages in the form of a pre-printed horoscope, overlayed with cryptic messages pasted predominantly 90 degrees clockwise, running down the page. These two communications were entitled Day-by-day forecast for Cancer and Day-by-day forecast for Leo. The second coming the day after the abduction of Leona LaRell Roberts (16) on December 10th 1969, leading to the possibility that this was a further play on words by the Zodiac Killer, who may have used the phrase "forecast for Leo" to insinuate the future plight of Leona Roberts. He may have had no hand in the abduction of Leona Roberts, but it wasn't unusual for the Zodiac Killer to insinuate his involvement in crimes committed by others. 

The two pasted communications in December (with Hidden and FLT a component of both) must have taken some forethought, so the idea that these two communications have no meaning whatsoever, doesn't quite sit right. These messages may need decoding just like the 340 cryptogram, albeit in a slightly different way. The choice of two horoscopes, when we consider the contemporary speculation behind the Zodiac Killer's choice of pseudonym, may have some significance. These two communications were straddled by both Fairfield letters, the first of which (December 7th 1969) contained sections of ciphertext that married up with the beginning and end of the 340 cipher. The months of July, November and December certainly seemed one big cryptic puzzle for the Zodiac Killer, but was it "one of his pleasures" in August. 

CANCER AND LEO-TWO ZODIAC COMMUNICATIONS?

2/6/2020

 
On December 10th 1969 a paste-up horoscope communication was mailed and postmarked PM from Sacramento entitled Day-By-Day Forecast for Cancer, followed by a similar communication mailed and postmarked PM from San Francisco on December 11th 1969 entitled Day-By-Day Forecast for Leo. Not published in the newspapers, it was clear that both of these communications had the same author just one day apart. The following is a summary of the abduction and murder of Leona LaRell Roberts by Steph54 on Websleuths:

On Wednesday, 10 December 1969, 16-year-old Leona Larell Roberts worked her first day at a part-time job at the White Front Discount Store in Pleasant Hill. After her 1-5 p.m. shift, she drove to her boyfriend's apartment (749 Tormey Ave, Rodeo) where she planned to cook him dinner. At the time, Leona attended K's American Beauty College in Napa, where she also lived with her mother. Within 15 minutes of arriving at her boyfriend's apartment, a neighbor heard a girl scream. The neighbor called the sheriff and soon after heard someone running down the stairs at the back of the apartment house followed by the slam of a door from the direction of the downstairs apartment where Leona's boyfriend lived. When the boyfriend arrived, he saw Leona's red VW out front but did not find her inside the apartment. The apartment was dark and the back door was unlocked. He noticed scuff marks on the wall near the back door. He found that a pair of his pants had been removed from the bedroom closet and left on the living room couch, the belt missing. He noticed Leona's work smock crumpled on the couch. A sheriff's deputy arrived 30 minutes after the call. Another neighbor told the deputy of seeing a white male, about 25 years old, short blonde hair, acting suspicious. He walked several times from the front door to the rear of a blue station wagon before driving away. On 28 December 1969, a man searching for driftwood on the beach at Bolinas Lagoon in Marin County found the nude body of Leona Roberts.

From the postmark dates and times it is extremely likely the Forecast for Cancer communication was mailed prior to the abduction/murder of Leona Roberts, with the Forecast for Leo communication likely mailed after her abduction/murder. This meant that the author of the Cancer communication on December 10th in Sacramento traveled to San Francisco to mail the second correspondence. The most direct route is shown below and uses only Interstate 80. This journey between communications passes just 0.9 miles from the 749 Tormey Avenue residence from where Leona Roberts was abducted. 

Picture
Less than 24 hours after the abduction/murder of Leona Roberts, the Forecast for Leo communication arrived. Was the perpetrator using a play on words to hint that her forecast was in his hands? The Forecast for Cancer communication was emblazoned with the pasted text of Zodiac - and we know that the Bay Area murder has become synonymous with abduction and murder. How many abductions and murders occurred in the Bay Area on December 10th 1969? Yet here we have two sinister communications mailed in Sacramento, followed by San Francisco, where the most direct route using Interstate 80 passes just 0.9 miles from the abduction site of Leona Roberts, which is then followed by a communication entitled Forecast for Leo. If this is a coincidence, it is one hell of a lucky one.

The question arises though - was the author of the two communications the Zodiac Killer or an impostor? Had somebody close to Leona Roberts planned her murder, and by mailing these communications with the word Zodiac in bold lettering, attempted to shift the focus of the investigation onto the Bay Area murderer, thereby making him the convenient fall guy? However, if the author of the Cancer and Leo communications wanted to achieve this goal, why would he be so cryptic? By sending a correspondence with nothing more than a heading of Day-By-Day Forecast for Leo, you are leaving open the possibility that investigators will not make the connection between the communication and the abduction of Leona Roberts. If you are attempting to lay the abduction squarely at the feet of Zodiac, then you simply create a communication using the pseudonym Zodiac and mentioning Leona Roberts by name, thereby creating no ambiguity. This may put the ball back in Zodiac's court.   
Picture
But it doesn't end there. Two more Zodiac communications were mailed either side of the above two forecasts. The first was mailed on December 7th 1969 from Fairfield, with the second arriving from Fairfield on December 16th 1969. These again fall directly along Interstate 80. If the four communications were the work of the Zodiac Killer, then we have a murderer mailing a correspondence from Fairfield on December 7th, before traveling northeast to Sacramento, then abducting Leona Roberts in Rodeo and continuing on to San Francisco, before heading back to Fairfield on December 16th. The author of four consecutive communications would possibly be using one direct route back and forth.

The Bus Bomb letter mailed on November 9th 1969 claimed seven victims, while the Melvin Belli letter mailed on December 20th 1969 claimed a search for number nine and ten. The December 7th 1969 Fairfield letter claimed no update to victim seven, leaving open the possibility that the abduction and murder of Leona Roberts on December 10th 1969 was victim number eight.
