Research on the Zodiac Killer
Lake Herman Road attack
On the evening of Friday, December 20, 1968, 17-year-old David Faraday and 16-year-old Betty Lou Jensen set out on what was intended to be a routine teenage date. Faraday had borrowed his mother's station wagon for the evening. The teenagers lived in Vallejo, California, and planned to attend a Christmas concert at Hogan High School, followed by a stop to grab a snack or visit friends. However, at some point during the night, they deviated from their expected route and drove out onto Lake Herman Road, a dark, two-lane highway connecting Vallejo and Benicia.
The Location and Approach
They parked the station wagon in a gravel turnout on the north side of Lake Herman Road, about a mile inside the Benicia city limits. This specific turnout was a well-known local lovers' lane—a secluded area where teenagers often parked to talk or listen to music. According to investigators' later reconstructions, the car was parked facing outward toward the highway. Sometime shortly after 11:00 PM, another vehicle pulled up and parked either directly behind them or closely alongside, or an individual walked up on foot from the unlit gravel shoulder, effectively trapping or confronting the teenagers.
The Shooting
The assailant approached the driver's side of the station wagon, carrying a .22 caliber semi-automatic pistol. Forensic evidence and ballistic reports indicated that the shooter fired at least one warning or intimidation shot through the roof of the car, grazing the interior lining. Faced with an armed intruder, Faraday and Jensen were ordered out of the vehicle.
David Faraday stepped out first, followed by Betty Lou Jensen. Based on powder burns and trajectory analysis, Faraday was shot at close range in the left ear/head area while standing near the left rear wheel of the station wagon. As Faraday collapsed, Betty Lou Jensen attempted to flee for her life, running toward an open field away from the road. The attacker pursued her, firing five shots into her back as she ran. She collapsed into the dirt and gravel just a few feet from the car, dying almost instantly from her wounds.
Discovery and Initial Response
The quiet of the rural road was broken only briefly by the gunfire. Shortly after midnight, a local resident passing by the area noticed the bodies and the parked station wagon, immediately alerting the Benicia Police Department and the Solano County Sheriff's Office.
When law enforcement arrived at the scene, they found Faraday still alive inside the vehicle or on the ground (he was rushed by ambulance to a local hospital but was pronounced dead upon arrival), while Jensen was already deceased outside. The investigation faced severe hurdles from the very beginning:
- Lack of Forensics: A heavy mist and winter frost covered the ground, washing away or destroying potential shoe prints, tire impressions, and physical transfer evidence around the turnout.
- No Witnesses: With no nearby homes or businesses, investigators had to rely entirely on passing motorists who saw very little in the pitch-dark conditions.
- No Motive: Because nothing was stolen from the victims and neither was sexually assaulted, the attack lacked an obvious financial or personal motive, leaving police perplexed.
Blue Rock Springs Park Attack
On the night of Saturday, July 5, 1969, 22-year-old Darlene Ferrin and 19-year-old Michael Mageau were spending time together in Vallejo, California. Ferrin had picked up Mageau late that evening, and after stopping briefly at her home, they drove out to Blue Rock Springs Park, a recreational area located about four miles east of Vallejo. They parked Ferrin's brown Chevrolet Corvair in an unlit gravel parking lot near the park's golf course shortly before midnight.
The Approach and Initial Attack
As they sat in the parked car talking, a light-colored vehicle—believed to be a Valiant—pulled into the lot and parked directly behind them or alongside them. The driver briefly left, drove away, and then returned a few minutes later, parking in a way that blocked or closely positioned next to the Corvair.
The driver stepped out of his car and walked quickly toward the passenger side of Ferrin's vehicle, carrying a flashlight and a 9mm semi-automatic pistol. Blinding the teenagers with the flashlight beam to prevent them from seeing his face, the attacker reached the passenger door window and opened fire without uttering a single word.
The Shooting
The gunman fired multiple rounds into the interior of the car. Both victims were struck immediately. Michael Mageau, despite being severely wounded in the jaw, shoulder, and limb, managed to turn toward the back seat or floorboards to shield himself. Darlene Ferrin was also hit multiple times.
Hearing Mageau groaning in pain, the attacker turned around, walked away from the car, and began to head back toward his own vehicle. However, hearing movement, the shooter abruptly turned back, approached the Corvair a second time, and fired additional shots into both victims at close range before walking back to his car and driving away into the night.
Discovery and Aftermath
Shortly before midnight, two young men driving through the park heard the gunshots and discovered the bloodied vehicle, quickly notifying local authorities.
- The Hospital Run: Police and ambulances rushed to the scene. Both victims were transported to Kaiser Foundation Hospital in Vallejo.
- Survival and Fatality: Darlene Ferrin was pronounced dead upon arrival at the hospital. Miraculously, Michael Mageau survived his critical wounds and was later able to provide investigators with a physical description of the attacker.
- The Confession Call: At approximately 12:40 AM, just about 40 minutes after the shooting, a man placed a phone call from a payphone at a Standard oil station in Vallejo
to the police department. He reported the crime, stated he had also shot the kids on Lake Herman Road the year prior, and calmly hung up.
Incident Report: Lake Berryessa Attack
- Date: September 27, 1969
- Location: A secluded shoreline area of Lake Berryessa in Napa County, California.
- The Victims: 20-year-old Bryan Hartnell and 22-year-old Cecelia Shepard (both college students at Pacific Union College).
The Attack
Unlike the previous two shootings, which took place late at night near parked cars, this attack happened in broad daylight (around 6:30 PM) in a relatively isolated area by the water.
- The Encounter: Hartnell and Shepard were relaxing on a blanket near the shoreline when a man approached them.
- The Disguise: The assailant wore a bizarre, homemade executioner-style black hood with eyeholes cut out and a white cross-circle symbol stitched onto the chest. He also wore sunglasses over the hood and brandished a pistol.
- The Ruse: The attacker claimed he was an escaped convict from a prison in Montana who needed their car and money to flee to Mexico. He forced Hartnell at gunpoint to tie up Shepard with pre-cut lengths of clothesline, and then bound Hartnell as well.
- The Stabbing: Once the victims were completely immobilized, the attacker unexpectedly pulled out a large knife and savagely stabbed both of them multiple times. He then walked away, leaving them for dead.
Aftermath and Evidence
- Survival and Tragically Lost Life: Bryan Hartnell miraculously survived eight stab wounds to his back. Cecelia Shepard suffered severe injuries and slipped into a coma, passing away two days later on September 29, 1969. Because Hartnell survived, he was able to give police a detailed account of the encounter.
- The Car Door Signature: Before leaving the scene, the killer walked up to Hartnell’s white Volkswagen Karmann Ghia and used a black felt-tip pen to draw his cross-circle symbol on the door. Directly beneath it, he wrote out the dates of his previous attacks and added a note detailing this new one: “Sept 27 69 6:30 by knife.”
- The Confession Call: Shortly after 7:40 PM that evening, a man walked into a payphone booth a few blocks away from the Napa County Sheriff's Department, called authorities to report the crime, and calmly claimed responsibility.
Incident Report: Presidio Heights Attack
- The Victim: 29-year-old Paul Stine, a taxicab driver.
- The Attack: Stine picked up a passenger in downtown San Francisco who asked to be driven to the intersection of Washington and Cherry Streets in the upscale Presidio Heights neighborhood. Once they arrived, the passenger shot Stine in the head with a 9mm pistol.
- The Aftermath: The killer took Stine's wallet and car keys, and then tore off a large piece of Stine's bloody shirt. Witnesses from a nearby home saw the crime in progress, called the police, and even watched the killer casually wipe down the taxi before walking away into the night.
Why This Attack is Crucial to the Case
- The Shift to the City: This was the first time the killer struck inside a busy city rather than a dark, isolated "lover's lane" or park, and it was the only confirmed murder where an adult male working alone was targeted.
- The Composite Sketch: Because eyewitnesses saw the killer clearly under a streetlamp as he walked away, police were able to draw the most famous composite sketch of the suspect—the face most people associate with the Zodiac today.
- The Proof of the Crime: A few days later, the San Francisco Chronicle received a letter from the Zodiac containing a swatch of Paul Stine's bloody shirt. This was definitive proof that the letter writer was indeed the person responsible for the murders, as the public did not yet know a piece of the shirt had been taken.
The murder of Cheri Jo Bates on October 30, 1966, at Riverside City College remains one of California's most notable unsolved cases, primarily due to its debated connection to the Zodiac Killer.
Overview of the Case
- Victim: Cheri Jo Bates (18 years old)
- Date & Location: October 30, 1966, at Riverside City College in Riverside, California
- The Incident: Bates visited the campus library during the evening to study. Investigators believe the killer disabled her Volkswagen Beetle by disconnecting a wire while she was inside. When she left the library at closing time and could not start her car, the attacker offered assistance and lured her into a dark area off Terracina Street, where he attacked her with a knife. Her body was discovered the following morning by a groundskeeper.
Key Evidence & Findings
- Forensic Evidence: Investigators recovered a man's Timex watch with a broken strap near the scene, along with military-style heel prints in the soil. Fingerprints and grease marks were also found on her vehicle.
- Motive: Robbery and sexual assault were ruled out, as her personal belongings and clothing were left undisturbed.
Anonymous Communications
- "The Confession": Nearly a month after the murder, carbon-copied, typewritten letters titled "The Confession" were mailed to local police and the local newspaper. The writer claimed responsibility and described disabling her car.
- Desk Carving: A poem carved into a wooden desk at the college library was later discovered, featuring themes and handwriting that some researchers linked to the killer.
The Zodiac Connection
- In 1970, journalists highlighted similarities between the Bates case and the Zodiac Killer's methods.
- In 1971, the Zodiac sent a postcard to news outlets claiming credit for "Riverside activity".
- Current Status: Riverside police generally maintain that the murder was likely committed by a local acquaintance or someone known to Bates, rather than the Zodiac. Modern DNA testing on evidence from the scene failed to match known Zodiac suspects, and the case remains an open cold-case investigation.
Robert Domingos and Linda Edwards Case Report
Date of Incident: June 4, 1963
Location: Gaviota Beach (near Lompoc, Santa Barbara County, California)
Victims: Robert George Domingos (18) and Linda Faye Edwards (17)
Overview of the Case
Robert Domingos and Linda Edwards were high school seniors who skipped school for "Senior Ditch Day" to sunbathe at a secluded beach off Highway 101. When they failed to return home that evening, family members searched the area and discovered Domingos's car parked along the highway.
Investigators later found the couple’s bodies inside a nearby driftwood shack on the beach.
Crime Scene & Reconstructed Sequence
- The Confrontation: Investigators theorize that an unknown gunman armed with a .22 caliber firearm approached the couple on the beach.
- The Restraints: The killer produced pre-cut lengths of rope and ordered Edwards to bind Domingos. Evidence suggested Domingos managed to break free or loosen the bindings, leading to an attempt by the couple to flee.
- The Shooting: The attacker opened fire as they ran, shooting both victims multiple times.
- Post-Attack Actions: The killer dragged both bodies into a nearby makeshift shack, collected their personal belongings, and placed them inside. The perpetrator then attempted to set fire to the shack using nearby brush and matches before fleeing, though the fire failed to consume the structure.
Key Forensic Evidence
- Weapon & Ammunition: Shell casings indicated a .22 caliber rifle or firearm was used.
- Restraints: Pre-cut rope segments were left at the scene.
- Motive: Robbery and sexual assault were ruled out by investigators, as personal items were left behind and there was no evidence of sexual violence.
The Zodiac Killer Connection
While officially an unsolved cold case handled by the Santa Barbara County Sheriff's Office, the murder shares notable similarities with later confirmed Zodiac Killer attacks:
- Modus Operandi: The targeting of a young couple in a secluded area near water mirrors the 1968 Lake Herman Road and 1969 Lake Berryessa attacks.
- Restraints: The use of pre-cut rope to bind victims directly parallels the tactic used in the 1969 Lake Berryessa attack.
- Weapon Choice: The use of .22 caliber ammunition matches the weapon type used in the Lake Herman Road attack.
- Geographic Hints: In later correspondence, the Zodiac Killer hinted at unconfirmed murders "down there" in Southern California.
Current Status: Santa Barbara Sheriff's investigators officially noted the similarities in the 1970s, but no definitive physical or forensic evidence has ever conclusively linked the Gaviota Beach murders to the Zodiac Killer. The case remains open and unsolved.
Ray Davis Case Report
Date of Incident: April 10, 1962
Location: Oceanside, California
Victim: Raymond "Ray" Davis, 27 years old
Overview of the Case
Ray Davis was a taxi driver for the Oceanside Yellow Cab Company. On the evening of April 10, 1962, he picked up a passenger for a route heading toward the St. Malo neighborhood in Oceanside. Shortly after, Davis was shot twice in the back through the driver's seat. His body was dragged from the cab and left in an alleyway, while the killer drove the taxi a short distance away before abandoning it.
Key Evidence & Phone Calls
- Pre-Crime Threat: A few hours before the murder, an anonymous caller phoned the Oceanside Police Department, stating, "I am going to kill a cab driver tonight."
- Post-Crime Taunt: The day after the murder, the same caller phoned police again, stating, "I killed that cabbie last night and I'm going to kill a bus driver next."
- Forensic Evidence: Davis was killed with a .22 caliber handgun. The physical evidence recovered was limited, and no fingerprints were matched to a suspect.
The Zodiac Connection
Investigators and researchers noted striking similarities between the Ray Davis murder and later confirmed Zodiac attacks:
- Targeting a Taxi Driver: The execution-style murder of a lone cab driver mirrors the October 1969 murder of Paul Stine in San Francisco.
- Phone Calls to Police: The killer called police to announce or taunt authorities about the crime, a hallmark behavior of the Zodiac.
- School Bus Threat: The threat to target a bus or bus driver directly parallels the Zodiac's later threats to attack a school bus full of children in his October 1969 letters.
- Weapon Choice: A .22 caliber weapon was also used in the 1968 Lake Herman Road Zodiac attack.
Current Status: The Oceanside Police Department reopened the case to explore potential ties to the Zodiac Killer. However, no physical or forensic evidence has ever conclusively connected the two, and the case remains an unsolved homicide.
Overview of the Case
Donna Lass was a registered nurse working at the Sahara Tahoe Casino in South Lake Tahoe, Nevada. On the night of September 6, 1970, she worked her scheduled shift at the casino clinic, with her last entry in the work log recorded at 1:45 AM. She vanished shortly after her shift ended.
The following day, an unidentified male called both her landlord and her supervisor at the casino, stating that Lass had left town abruptly due to a family emergency. Her family later confirmed that no such emergency existed, and her personal belongings—including her car—were left behind at her apartment.
Key Evidence & Communications
- The Call: The caller who claimed Lass left town was never identified, leading investigators to believe the perpetrator made the call to delay a missing persons investigation.
- The "Pines Card" Postcard: On March 22, 1971, the San Francisco Chronicle received a postcard made from a collage of magazine cutouts depicting an advertisement for a housing development at Lake Tahoe. The card contained phrases like "Sought Victim 12", "Peeking through the pines", and "pass Lake Tahoe areas". The cross-circle Zodiac symbol was drawn in the space for the return address.
- Lack of Scene Evidence: No physical evidence of a struggle was found at the casino clinic or her apartment, and her body was never recovered.
The Zodiac Connection
- Correspondence: The 1971 "Pines Card" is the primary link tying Lass to the Zodiac Killer, leading many researchers to believe the killer was taking credit for her disappearance.
- Suspect Overlap: Suspect Lawrence Kane worked at the same Sahara Tahoe hotel-casino around the time Lass disappeared, which drew significant interest from independent researchers.
Current Status: The Placer County and El Dorado County Sheriff's Offices handle the case as an open missing person and cold-case homicide investigation. While the postcard created a strong public link to the Zodiac Killer, law enforcement has never definitively proven that the postcard was authentic or that the Zodiac was responsible for her disappearance.
Snoozy and Furlong Murders
Date of Incident: August 3, 1969
Location: San Jose, California
Victims: Deborah Furlong (14) and Kathryn "Kathy" Snoozy (15)
Overview of the Case
On the afternoon of August 3, 1969, teenagers Deborah Furlong and Kathy Snoozy went for a walk in Almaden Meadows Park in San Jose. When they failed to return home by evening, their families initiated a search. Their bodies were discovered later that day in an undeveloped, wooded area of the park.
Investigation and Zodiac Speculation
- Initial Zodiac Suspicions: Because the murders occurred during the height of the Zodiac Killer's activity in Northern California, media outlets and the public quickly speculated a connection.
- Media Calls: Shortly after the news of the double homicide broke, phone calls were made to local newspaper offices by an individual claiming the Zodiac Killer committed the attack.
- Key Differences: Despite the public speculation, investigators noted that the attack differed significantly from confirmed Zodiac incidents in both geography and execution, as the killer did not leave letters, ciphers, or phone calls directly to police regarding this specific scene.
Case Resolution
Unlike many other cases linked by rumor to the Zodiac, the Snoozy-Furlong murders were definitively solved:
- Perpetrator: In 1972, a local man named Karl Francis Werner was arrested and charged with the murders of Deborah Furlong and Kathy Snoozy, as well as the 1971 murder of 18-year-old Kathy Bilek.
- Conviction: Werner confessed to the killings, and physical evidence directly tied him to the crime scenes. He was convicted and sentenced to life imprisonment.
Current Status: Resolved. The Snoozy and Furlong case was officially closed and fully cleared from any association with the Zodiac Killer.
Kathleen Johns Case Report
Date of Incident: March 22, 1970
Location: Highway 132 near Modesto, California
Individual: Kathleen Johns (22 years old at the time)
Overview of the Incident
On the night of March 22, 1970, Kathleen Johns was driving along Highway 132 near Modesto while seven months pregnant and traveling with her 10-month-old daughter.
A driver in a car behind her began flashing his headlights and honking his horn. After both vehicles pulled over, the man informed Johns that her rear wheel was wobbling. He offered to tighten the lug nuts, but after he drove off, the wheel completely fell off when Johns attempted to pull back onto the road.
The man returned and offered her a ride to a nearby gas station. Johns accepted, entering his car with her daughter. However, instead of stopping at a service station, the driver bypassed several open businesses and drove aimlessly around back roads for roughly one to two hours, making verbal threats regarding her safety.
When the car slowed down at an intersection, Johns managed to open the door, jump out of the vehicle with her daughter, and hide in nearby bushes. The driver searched for her briefly before driving away.
Key Evidence & Identification
- The Police Station Identification: After receiving help from a passing motorist, Johns went to the Patterson Police Department to report the incident. While inside the station, she saw the police composite sketch of the Zodiac Killer (created after the Paul Stine murder) on the wall and identified him as the man who had abducted her.
- Vehicle Discovery: Her station wagon was later found burned and gutted on the side of the highway.
The Zodiac Connection
- Letter Reference: In a letter sent to the San Francisco Chronicle on July 24, 1970, the Zodiac Killer explicitly referenced driving a woman and her baby around for a few hours before she escaped, claiming responsibility for the incident.
- Skepticism: Investigators and researchers remain split over whether Johns encountered the actual Zodiac:
- Arguments For: She identified the sketch independently, and the killer claimed credit in later correspondence.
- Arguments Against: The driver's physical description given by Johns varied slightly from other witness reports, and some researchers argue the Zodiac may have simply read about her ordeal in local news reports and taken credit after the fact.
Current Status: The incident remains an unconfirmed Zodiac-linked event. It is officially treated as an unsolved abduction and arson case by local authorities.
1. Arthur Leigh Allen (The Prime Suspect)
- Appearance: Caucasian male, ~6'0"–6'2", heavy build (~200–250 lbs), balding, size 10½ shoe.
- Reason for Suspicion: Wore a Zodiac brand watch with the cross-circle logo, owned a size 10½ Wing Walker boot matching the Lake Berryessa tracks, and made incriminating statements to friends. Was served multiple search warrants by police.
- Why Excluded/Unconfirmed: Fingerprints, handwriting, and partial DNA samples taken from letter stamps did not match him.
2. Lawrence Kane (also known as Lawrence Kaye)
- Appearance: Caucasian male, ~5'9", medium build, dark hair, wore heavy-rimmed glasses (resembling the Presidio Heights composite sketch).
- Reason for Suspicion: Suffered a brain injury in 1965 that affected his impulse control. Worked at the same hotel in Lake Tahoe as Donna Lass (a missing woman often speculated to be an unconfirmed Zodiac victim). Was identified from a photo array by Kathleen Johns, a woman who escaped a kidnapper in 1970.
- Why Excluded/Unconfirmed: No physical or forensic evidence links him to the confirmed crime scenes.
3. Ross Sullivan
- Appearance: Caucasian male, ~6'2", heavy build (~200–300 lbs), wore thick glasses and military-style boots.
- Reason for Suspicion: Worked at the Riverside City College library at the time of the 1966 murder of Cheri Jo Bates (an unconfirmed Zodiac-linked case). Coworkers found him deeply unsettling, noting that he wore combat boots (similar to impressions found at the Bates scene) and vanished from the area shortly after the murder.
- Why Excluded/Unconfirmed: Suffered from severe mental illness and was institutionalized multiple times, creating timeline conflicts with some of the Zodiac attacks. No physical evidence connects him to the San Francisco Bay Area killings.
4. Paul Doerr
- Appearance: Caucasian male, ~5'9", stocky build, short hair, wore glasses.
- Reason for Suspicion: Proposed in 2022 by author Jarett Kobek. Doerr was a Vallejo resident, naval shipyard worker, and avid creator of amateur fanzines. His writings contained obscure formulas for homemade explosives similar to those in Zodiac letters, as well as distinct cross-circle symbols and specific spelling errors matching the killer's habits.
- Why Excluded/Unconfirmed: He was never investigated by police while alive, and no DNA or fingerprint testing has linked him to the physical evidence.
5. Gary Francis Poste
- Appearance: Caucasian male, medium height, stocky build with distinctive forehead scars.
- Reason for Suspicion: Highlighted in 2021 by an independent group called The Case Breakers. They pointed to his history of violence, military experience, physical scars that mirrored lines in the composite sketch, and paints/chemicals in his darkroom.
- Why Excluded/Unconfirmed: Law enforcement (including the FBI and Riverside Police) publicly refuted the claim, stating there is no direct evidence connecting Poste to the Zodiac murders and that the case remains officially open.
6. Earl Van Best Jr.
- Appearance: Caucasian male, ~5'9", thin face, thick-rimmed glasses, remarkably similar in appearance to the 1969 police sketch.
- Reason for Suspicion: Accused by his biological son, Gary Stewart, in the 2014 book The Most Dangerous Animal. Stewart claimed his father's initials appeared in ciphers and that his handwriting closely mirrored the Zodiac's.
- Why Excluded/Unconfirmed: Handwriting experts dismissed the comparisons, and independent codebreakers debunked the cipher claims.
7. Richard Gaikowski
- Appearance: Caucasian male, ~5'8", medium build, wore thick glasses.
- Reason for Suspicion: Worked as a journalist for an anti-establishment San Francisco newspaper called Good Times. Proponents of this theory noted that the newspaper published articles matching Zodiac letter themes, and a dispatcher claimed to recognize his voice from a police call.
- Why Excluded/Unconfirmed: Thoroughly investigated by law enforcement, but no fingerprints, DNA, or direct physical evidence ever tied him to the crimes.
Summary of the Evidence Dilemma
Despite dozens of suspects named by police, authors, and amateur sleuths over the past five decades, no single suspect has ever matched both the circumstantial evidence and the hard physical evidence (fingerprints, handwriting, and DNA).
Arthur Leigh Allen, is the Zodiac Killer. I can prove this because:
- He is disputed for being the Zodiac Killer, as forensic tests and handwriting tests show. But, this can lead to inaccuracy, since forensic technology during the 60s-70s era was still developing and not great. For the handwriting part, he could have used his non-dominant hand, or intentionally changed writing style to confuse analysts.
- He can match the suspect description, caucasian, military boots sized 10 and a half. But the witness, Officer Fouke, says otherwise. His description might show false results as the circumstances can explain the setting was dark, and determining the suspect’s height and weight under such conditions is really hard and inaccurate.
- He says that he had visited Napa county during the time period in which the Lake Berryessa murder occurred, and made a really suspicious claim, stating: “The two knives I had in my car with blood on them, the blood came from a chicken I had killed.” He had brought this topic up spontaneously, which further led to more suspicions.
- A search party at his home, Sunset Trailer Park, Santa Rosa, California, found many weapons and the military style boots, which could further lead to more evidence, and hence, making him a prime suspect.
