Why is zodiac called zodiac killer?

The Zodiac originated the name himself in a series of taunting letters and cards that he mailed to regional newspapers, threatening killing sprees and bombings if they were not printed.

Pseudonym of a serial killer in California

For the New York City Zodiac copycat, see Heriberto Seda . For the Japanese Zodiac copycat, see Kobe child murders The Zodiac Killer[n 2] is the pseudonym of an unidentified serial killer[1] who operated in Northern California in the late 1960s.[n 1] The case has been described as the most famous unsolved murder case in American history.[2] It became a fixture of popular culture and inspired amateur detectives to attempt to solve it. The Zodiac murdered five known victims in the San Francisco Bay Area between December 1968 and October 1969, operating in rural, urban and suburban settings. He targeted young couples and a lone male cab driver. His known attacks took place in Benicia, Vallejo, unincorporated Napa County, and the city of San Francisco proper. Two of his wounded victims survived. The Zodiac claimed to have murdered 37 victims. He has been linked to several other cold cases, some in Southern California or outside the state. The Zodiac coined this name in a series of taunting letters and cards that he mailed to regional newspapers, in which he threatened killing sprees and bombings if they were not printed. Some of the letters included cryptograms, or ciphers, in which the killer claimed that he was collecting his victims as slaves for the afterlife. Of the four ciphers he produced, two remain unsolved, and one was cracked only in 2020. While many theories regarding the identity of the killer have been suggested, the only suspect authorities ever publicly named was Arthur Leigh Allen,[3] a former elementary school teacher and convicted sex offender who died in 1992. Although the Zodiac ceased written communications around 1974, the unusual nature of the case led to international interest that has been sustained throughout the years.[4] The San Francisco Police Department marked the case "inactive" in April 2004, but re-opened it at some point prior to March 2007.[5][6] The case also remains open in the city of Vallejo, as well as in Napa and Solano counties.[7] The California Department of Justice has maintained an open case file on the Zodiac murders since 1969.[8]

Murders and correspondence

Confirmed murders

Although the Zodiac claimed in letters to newspapers to have committed 37 murders, investigators agree on seven confirmed assault victims, five of whom died and two survived. They are: David Arthur Faraday, 17, and Betty Lou Jensen, 16: shot and killed on December 20, 1968, on Lake Herman Road, within the city limits of Benicia. Michael Renault Mageau, 19, and Darlene Elizabeth Ferrin, 22: shot on July 4, 1969, in the parking lot of Blue Rock Springs Park in Vallejo. Mageau survived the attack; Ferrin was pronounced dead on arrival at Kaiser Foundation Hospital. Bryan Calvin Hartnell, 20, and Cecelia Ann Shepard, 22: stabbed on September 27, 1969, at Lake Berryessa in Napa County. Hartnell survived, but Shepard died as a result of her injuries a couple days later on September 29. Paul Lee Stine, 29: shot and killed on October 11, 1969, in the Presidio Heights neighborhood of San Francisco.

Lake Herman Road murders

David Arthur Faraday and Betty Lou Jensen

The first murders widely attributed to the Zodiac Killer were the shootings of high school students Betty Lou Jensen and David Arthur Faraday on December 20, 1968 on Lake Herman Road, just inside the city limits of Benicia. The couple were on their first date and planned to attend a Christmas concert at Hogan High School, about three blocks from Jensen's home. They visited a friend before stopping at a local restaurant and driving out on Lake Herman Road, a popular area for young couples. At about 10:15 p.m., Faraday parked his mother's Rambler in a gravel turnout, which was a well-known lovers' lane. Shortly after 11:00 p.m., their bodies were found by Stella Borges, who lived nearby. The Solano County Sheriff's Department investigated the crime but no leads developed.[9] Using available forensic data, Robert Graysmith later speculated in his 1976 account that another car pulled into the turnout just prior to 11:00 p.m. and parked beside the couple. The killer may have exited the second car and walked toward the Rambler, possibly ordering the couple out of it. It appeared that Jensen had exited the car first, but when Faraday was halfway out, the killer shot him in the head. The killer shot Jensen five times in the back as she fled; her body was found 28 feet from the car. The killer drove off after this.[10]

Blue Rock Springs murder

Just before midnight on July 4, 1969, Darlene Ferrin and Michael Mageau drove into the Blue Rock Springs Park in Vallejo and parked. It is four miles (6.4 km) from the Lake Herman Road murder site. While the couple sat in Ferrin's car, a second car drove into the lot and parked alongside them but almost immediately drove away. Returning about 10 minutes later, this second car parked behind them. The driver of the second car exited and approached the passenger side door of Ferrin's car, carrying a flashlight and a 9 mm Luger. The killer directed the flashlight into Mageau's and Ferrin's eyes before shooting at them, firing five times. Both victims were hit, and several bullets passed through Mageau and into Ferrin. The killer walked away from the car but returned and shot each victim twice more before driving off.[11] On July 5, 1969, at 12:40 a.m., a man phoned the Vallejo Police Department to report and claim responsibility for the attack. The caller also took credit for the murders of Jensen and Faraday six and a half months earlier. Police traced the call to a phone booth at a gas station at Springs Road and Tuolumne, located about three-tenths of a mile (500 m) from Ferrin's home and a few blocks from the Vallejo Police Department.[12] Ferrin was pronounced dead at the hospital. Mageau survived the attack despite being shot in the face, neck and chest.[13] Mageau described his attacker as a 26-to-30-year-old, 195-to-200-pound (88 to 91 kg) or possibly even more, 5-foot-8-inch (1.73 m) white male with short, light brown curly hair.

First letters from the Zodiac

"I like killing people because it is so much fun it is more fun than killing wild game in the forrest because man is the most dangeroue anamal of all to kill something gives me the most thrilling experence it is even better than getting your rocks off with a girl the best part of it is thae when I die I will be reborn in paradice and all the I have killed will become my slaves I will not give you my name because you will try to sloi down or atop my collectiog of slaves for my afterlife ebeorietemethhpiti" —The solution to Zodiac's 408-symbol cipher, solved in August 1969, including faithful transliterations of spelling and grammar errors in the original. The meaning, if any, of the final eighteen letters has not been determined.[n 3][14] On August 1, 1969, three letters purportedly prepared by the killer were received at the Vallejo Times Herald, the San Francisco Chronicle, and The San Francisco Examiner. The nearly identical letters, subsequently described by a psychiatrist to have been written by "someone you would expect to be brooding and isolated",[15] took credit for the shootings at Lake Herman Road and Blue Rock Springs. Each letter also included one-third of a 408-symbol cryptogram which the killer claimed contained his identity. The killer demanded they be printed on each paper's front page or he would "cruse [sic] around all weekend killing lone people in the night then move on to kill again, until I end up with a dozen people over the weekend".[16] The Chronicle published its third of the cryptogram on page four of the next day's edition. An article printed alongside the code quoted Vallejo Police Chief Jack E. Stiltz as saying "We're not satisfied that the letter was written by the murderer" and requested the writer send a second letter with more facts to prove his identity.[17] The threatened murders did not happen, and all three parts of the cryptogram were eventually published. On August 7, 1969, The San Francisco Examiner received a letter with the salutation, "Dear Editor This is the Zodiac speaking." This was the first time the killer had used this name for identification. The letter was a response to Chief Stiltz's request for more details that would prove he had killed Faraday, Jensen and Ferrin. In it, the Zodiac included details about the murders that had not yet been released to the public. He also said that when the police cracked his code "they will have me".[18] Author Søren Roest Korsgaard explains that the "episode" paragraph in this letter referenced the Alfred Hitchcock Presents episode "Museum Piece"/[19] The attachment of a light to a gun was a plot element which Zodiac adopted. The episode dialog also contains the phrase "the most dangerous game". Zodiac was both referring to and acting out Hitchcock story elements. On August 8, 1969, Donald and Bettye Harden of Salinas, California cracked the 408-symbol cryptogram. It contained a misspelled message in which the killer seemed to reference "The Most Dangerous Game". The author also said that he was collecting slaves for his afterlife.[n 4] No name appears in this decoded text. The killer said that he would not give away his identity because it would slow down or stop his slave collection.[14]

Lake Berryessa murder

A view of Lake Berryessa

On September 27, 1969, Pacific Union College students Bryan Hartnell and Cecelia Shepard were picnicking at Lake Berryessa on a small island connected by a sand spit to Twin Oak Ridge. A white man, about 5 feet 11 inches (1.80 m) weighing more than 170 pounds (77 kg), approached them wearing a black executioner's-type hood with clip-on sunglasses over the eye-holes and a bib-like device on his chest that had a white three-by-three-inch (7.6 cm × 7.6 cm) cross-circle symbol on it. He approached them with a gun, which Hartnell believed to be a .45. The hooded man claimed to be an escaped convict from a jail with a two-word name, in either Colorado or Montana (a police officer later inferred that the man had been referring to a jail in Deer Lodge, Montana), where he had killed a guard and subsequently stolen a car. He said that he needed their car and money to travel to Mexico because the stolen vehicle was "too hot".[21] The killer had brought precut lengths of plastic clothesline and told Shepard to tie up Hartnell before he tied her up. The killer checked, and tightened Hartnell's bonds after discovering that Shepard had bound Hartnell's hands loosely. Hartnell initially believed this event to be a bizarre robbery, but the man drew a knife and stabbed them both repeatedly. Hartnell suffered six and Shepard ten wounds in the process.[22][23] The killer hiked 500 yards (460 m) up to Knoxville Road, drew the cross-circle symbol on Hartnell's car door with a black felt-tip pen, and wrote beneath it:[24][25]

Vallejo

by knife[24][25]

At 7:40 p.m., the killer called the Napa County Sheriff's office from a pay telephone to report this latest crime. The caller first stated to the operator that he wished to "report a murder – no, a double murder,"[26] before saying that he had committed the crime. KVON radio reporter Pat Stanley found the phone, still off the hook, a few minutes later at the Napa Car Wash on Main Street in Napa. It was a few blocks from the sheriff's office, and 27 miles (43 km) from the crime scene. Detectives lifted a still-wet palm print from the telephone but were never able to match it to any suspect.[27] After hearing the victims' screams for help, a man and his son fishing in a nearby cove discovered the couple and got help by contacting park rangers. Napa County Sheriff's deputies Dave Collins and Ray Land were the first law enforcement officers to arrive at the crime scene.[28] Shepard was conscious when Collins arrived, and provided him with a detailed description of the attacker. Hartnell and Shepard were taken to Queen of the Valley Hospital in Napa by ambulance. Shepard lapsed into a coma during transport, never regained consciousness, and died two days later. Hartnell survived to recount his tale to the press.[29][30] Napa County detective Ken Narlow, who was assigned to the case from the outset, worked on solving the crime until his retirement from the department in 1987.[31]

Presidio Heights murder

San Francisco from the Presidio, 1966

Two weeks later, on October 11, 1969, a white male passenger entered the cab driven by Paul Stine at the intersection of Mason and Geary Streets (one block west from Union Square) in San Francisco, requesting to be driven to Washington and Maple streets in Presidio Heights. For reasons unknown, Stine drove one block past Maple to Cherry Street. The passenger shot Stine once in the head with a 9 mm handgun, took the driver's wallet and car keys, and tore away a section of his bloodstained shirt tail. Three teenagers across the street at 9:55 p.m. saw the incident, and phoned the police while the crime was in progress. They observed a man wiping the cab down before walking away toward the Presidio, one block to the north.[32] Two blocks from the crime scene, patrol officers Don Fouke and Eric Zelms, responding to the call, observed a white man walking along the sidewalk east on Jackson Street and stepping onto a stairway leading up to the front yard of one of the homes on the north side of the street; the encounter lasted only five to ten seconds.[33] Fouke estimated the white male pedestrian to be 35 to 45 years old, 5 feet 10 inches (1.78 m) tall with a crew cut, similar to but slightly older than the description provided by the teenagers who observed the killer in and out of Stine's cab. The teenagers described the suspect to be 25 to 30 years old with a crew cut and standing approximately 5 feet 8 inches (1.73 m) to 5 feet 9 inches (1.75 m) tall. However, the police radio dispatcher had alerted officers to look out for a black suspect, so Fouke and Zelms drove past the perpetrator without stopping; the mixup in descriptions remains unexplained. A search ensued, but no suspects were found. This was the last officially confirmed murder by the Zodiac Killer. The Stine murder was initially believed to be a routine robbery that had escalated into homicidal violence. However, on October 13, the San Francisco Chronicle received a new letter from Zodiac that claimed credit for the killing and contained a torn section of Stine's bloody shirt to "prove this" fact.[34] The three teen witnesses worked with a police artist to prepare a composite sketch of Stine's killer; a few days later, this police artist returned, working with the witnesses to prepare a second composite sketch. Detectives Bill Armstrong and Dave Toschi were assigned to the case.[n 5] The San Francisco Police Department investigated an estimated 2,500 suspects over a period of years.[36]

1969 mailings

"I hope you are having lots of fan in trying to catch me that wasnt me on the tv show which bringo up a point about me I am not afraid of the gas chamber becaase it will send me to paradlce all the sooher because e now have enough slaves to worv for me where every one else has nothing when they reach paradice so they are afraid of death I am not afraid because i vnow that my new life is life will be an easy one in paradice death" —The solution to Zodiac's 340-symbol cipher, solved in December 2020, including faithful transliterations of spelling and grammar errors in the original.[n 6][2][37] On October 14, 1969, the Chronicle received another letter from the Zodiac, this time containing a swatch of Paul Stine's shirt tail as proof he was the killer; it also included a threat about killing schoolchildren on a school bus. To do this, Zodiac wrote, "just shoot out the front tire & then pick off the kiddies as they come bouncing out". At 2:00 p.m. on October 20, 1969, someone claiming to be the Zodiac called the Oakland Police Department (OPD), demanding that one of two prominent lawyers, F. Lee Bailey or Melvin Belli, appear on A.M. San Francisco, a talk show on KGO-TV hosted by Jim Dunbar. Bailey was not available, but Belli did appear on the show. Dunbar appealed to the viewers to keep the lines open. Someone claiming to be the Zodiac called several times, and Belli asked the caller for a less ominous name and the caller picked "Sam". The caller said he would not reveal his true identity as he was afraid of being sent to the gas chamber (then California's capital punishment method). Belli arranged a rendezvous to meet the caller outside a shop on Mission Street in Daly City, but no one arrived. The call was later traced back to a patient in a mental institution, and investigators concluded that the man was not the Zodiac.[38] On November 8, 1969, the Zodiac mailed a card with another cryptogram consisting of 340 characters.[39] This cipher, dubbed "Z-340", remained unsolved for over 51 years. On December 5, 2020, it was deciphered by an international team of private citizens, including American software engineer David Oranchak, Australian mathematician Sam Blake and Belgian programmer Jarl Van Eycke [nl]. In the decrypted message, the Zodiac denied being the "Sam" who spoke on A.M. San Francisco, explaining that he was not afraid of the gas chamber "because it will send me to paradice [sic] all the sooner".[2] The team submitted their findings to the Federal Bureau of Investigation, which verified the discovery.[2] The FBI stated that the decoded message gave no further clues to the identity of Zodiac.[40][41]

On November 9, 1969, the Zodiac mailed a seven-page letter stating that two policemen stopped and actually spoke with him three minutes after he shot Stine. Excerpts from the letter were published in the Chronicle on November 12, including the Zodiac's claim;[42][43] that same day, Officer Don Fouke wrote a memo explaining what had happened on the night of Stine's murder. On December 20, 1969, exactly one year after the murders of David Faraday and Betty Lou Jensen, the Zodiac mailed a letter to Belli that included another swatch of Stine's shirt; the Zodiac said that he wanted Belli to help him.[44]

Suspected victims

Various authors speculated at the time of the killings that other murders and attacks may have been the work of the Zodiac, but none have been confirmed:

Cheri Jo Bates

On October 30, 1966, an 18-year-old student at Riverside City College, Cheri Jo Bates, spent the evening at the campus library annex until it closed at 9:00 p.m. Neighbors reported hearing a scream around 10:30 p.m. Bates was found dead the next morning, a short distance from the library, between two abandoned houses slated to be demolished for campus renovations. The wires in her Volkswagen's distributor cap had been pulled out. She was brutally beaten and stabbed to death. A man's Timex watch with a torn wristband was found nearby.[54] The watch had stopped at 12:24,[55] but police believe that the attack had occurred much earlier.[54] Riverside Press-Enterprise November 29, 1966 The typewritten confession received by Riverside police and theNovember 29, 1966 A month later, on November 29, 1966, nearly identical typewritten letters were mailed to the Riverside police and the Riverside Press-Enterprise, titled "The Confession". The author claimed responsibility for the Bates murder, providing details of the crime that were not released to the public. The author warned that Bates "is not the first and she will not be the last".[56] In December 1966, a poem was discovered carved into the bottom side of a desktop in the Riverside City College library. Titled "Sick of living/unwilling to die", the poem's language and handwriting resembled that of the Zodiac's letters. It was signed with what were assumed to be the initials rh. During the 1970 investigation, Sherwood Morrill, California's top "questioned documents" examiner, expressed his opinion that the poem was written by the Zodiac.[57] On April 30, 1967, exactly six months after the Bates murder, Bates' father Joseph, the Press-Enterprise, and the Riverside police all received nearly identical letters. In handwritten scrawl, the Press-Enterprise and police copies read "Bates had to die there will be more," with a small scribble at the bottom that resembled the letter Z. Joseph Bates' copy read "She had to die there will be more," this time without the Z signature.[58] In August 2021, the Riverside Police Department's Homicide Cold Case Unit announced that the author of the handwritten letters anonymously contacted investigators in 2016 and was identified via DNA analysis in 2020. He admitted the correspondence was a distasteful hoax and apologized, explaining that he had been a troubled teenager and wrote the letters as a means of seeking attention. Investigators confirmed that the author was not the Zodiac.[59] On March 13, 1971, five months after Avery's article linking the Zodiac to the Riverside murder, the Zodiac mailed a letter to the Los Angeles Times. In the letter he credited the police, instead of Avery, for discovering his "Riverside activity, but they are only finding the easy ones, there are a hell of a lot more down there".[60] The connection between Cheri Jo Bates, Riverside and the Zodiac remains uncertain. Paul Avery and the Riverside Police Department maintain that the Bates homicide was not committed by the Zodiac, but did concede that some of the Bates letters may have been his work to claim credit falsely.[61]

Donna Lass

The Lake Tahoe card addressed to Paul Avery on March 22, 1971

On March 22, 1971, a postcard to the Chronicle, addressed to "Paul Averly" [sic] and believed to be from the Zodiac, appeared to claim responsibility for the disappearance of Donna Lass on September 6, 1970.[53] Made from a collage of advertisements and magazine lettering, it featured a scene from an advertisement for Forest Pines condominiums and the text "Sierra Club", "Sought Victim 12",[62] "peek through the pines", "pass Lake Tahoe areas", and "around in the snow". The Zodiac's crossed-circle symbol was in both the place of the usual return address and the lower-right section of the front face of the postcard.[63] Lass was a nurse at the Sahara Tahoe hotel and casino. She worked until about 2:00 a.m. on September 6, 1970,[63] treating her last patient at 1:40 a.m. Later that same day, both Lass's employer and her landlord received phone calls from an unknown male falsely claiming that Lass had left town because of a family emergency.[64] Lass was never found. What appeared to be a gravesite was discovered near the Clair Tappaan Lodge in Norden, California, on Sierra Club property.[65] No evidence has been uncovered to definitively connect the Lass disappearance with the Zodiac Killer.

Kathleen Johns

On the night of March 22, 1970, Kathleen Johns was driving from San Bernardino to Petaluma to visit her mother. She was seven months pregnant and had her 10-month-old daughter beside her.[66] While heading west on Highway 132 near Modesto, a car behind her began honking its horn and flashing its headlights. She pulled off the road and stopped. The man in the car parked behind her, approached her car, stated that he observed that her right rear wheel was wobbling, and offered to tighten the lug nuts. After finishing his work, the man drove off; yet when Johns pulled forward to re-enter the highway the wheel almost immediately came off the car. The man returned, offering to drive her to the nearest gas station for help. She and her daughter climbed into his car.[67] During the ride, the car passed several service stations, but the man did not stop. For about 90 minutes, he drove back and forth around the back roads near Tracy. When Johns asked why he was not stopping, he would change the subject. When the driver finally stopped at an intersection, Johns jumped out with her daughter and hid in a field. The driver searched for her using a flashlight, telling her that he would not hurt her, before eventually giving up. Unable to find her, he got back into the car and drove off. Johns hitched a ride to the police station in Patterson.[52] When Johns gave her statement to the sergeant on duty, she noticed the police composite sketch of Paul Stine's killer and recognized him as the man who had abducted her and her child.[68] Fearing that he might return to kill them all, the sergeant had Johns wait in the dark at nearby Mil's Restaurant. When her car was found, it had been gutted and torched.[68] Most accounts say that the man threatened to kill Johns and her daughter while driving them around,[69] but at least one police report disputes that.[52] Johns's account to Paul Avery of the Chronicle indicates that her abductor left his car and searched for her in the dark with a flashlight;[70] however, in one report she made to the police, she stated that he did not leave the vehicle.[52]

Discussions of other possible attacks

There is no consensus on the number of people Zodiac attacked or the years in which the attacks took place. The attacks on Kathleen Johns and Donna Lass, if attributable to Zodiac, suggest a new MO. The targets would be individual females rather than couples, and they would be abducted. Many of the Santa Rosa Hitchhiker Murders exhibit these themes and have long been considered possible Zodiac crimes. The strangulation of some of these victims is in line with the Zodiac's October 1970 claim to kill by "Rope." In 1986, Robert Graysmith published a list of 49 confirmed and possible Zodiac targets[71]. This list includes some of the Santa Rosa Hitchhiker Murder victims.

Further Zodiac communications

The crosshair-like symbol with which the Zodiac signed his letters

Zodiac continued to communicate with authorities for the remainder of 1970 via letters and greeting cards to the press. In a letter postmarked April 20, 1970, the Zodiac wrote, "My name is _____," followed by a 13-character cipher that has not been solved to this day.[72] The Zodiac went on to state that he was not responsible for the recent bombing of a police station in San Francisco (referring to the February 18, 1970, death of Sgt. Brian McDonnell two days after the bombing at Park Station in Golden Gate Park)[73] but added "there is more glory to killing a cop than a cid [sic] because a cop can shoot back." The letter included a diagram of a bomb the Zodiac claimed that he would use to blow up a school bus. At the bottom of the diagram, he wrote: " = 10, SFPD = 0."[74] Zodiac sent a greeting card postmarked April 28, 1970 to the Chronicle. Written on the card was "I hope you enjoy yourselves when I have my BLAST," followed by the Zodiac's cross-circle signature. On the back of the card, the Zodiac threatened to use the bus bomb soon unless the newspaper published the full details that he had written. He also wanted to start seeing people wearing "some nice Zodiac butons [sic]".[75] In a letter postmarked June 26, 1970, the Zodiac stated that he was upset that he did not see people wearing Zodiac buttons. He wrote, "I shot a man sitting in a parked car with a .38."[76] The Zodiac was possibly referring to the murder of 25-year-old Sgt. Richard Radetich one week earlier. At 5:25 a.m. on June 19, Radetich was writing a parking ticket in his squad car when an assailant unrelated to the traffic violation shot him in the head with a .38-caliber pistol through the closed driver's side window.[77] Radetich died 15 hours later. The San Francisco Police Department (SFPD) denies that the Zodiac was involved; the murder remains unsolved.[73] Included with the letter was a Phillips 66 roadmap of the San Francisco Bay area. On the image of Mount Diablo, the Zodiac had drawn a crossed circle similar to those from previous correspondence. At the top of the crossed circle, he placed a zero, a three, six, and a nine. The accompanying instructions stated that the zero was "to be set to Mag. N."[78] The letter also included a 32-letter cipher that the killer claimed would, in conjunction with the code, lead to the location of a bomb that he had buried and set to detonate in the fall. The cipher was never decoded, and the alleged bomb was never located. The killer signed the note with " - 12, SFPD - 0". In a letter to the Chronicle postmarked July 24, 1970, the Zodiac took credit for Kathleen Johns's abduction, four months after the incident.[79] In a July 26, 1970 letter, the Zodiac paraphrased a song from The Mikado, adding his own lyrics about making a "little list" of the ways in which he planned to torture his "slaves" in "paradice [sic]".[80] The letter was signed with a large, exaggerated crossed-circle symbol and a new score: " = 13, SFPD = 0".[81] A final note at the bottom of the letter stated, "P.S. The Mt. Diablo code concerns Radians + # inches along the radians."[82] In 1981, a close examination of the radian hint by Zodiac researcher Gareth Penn led to the discovery that a radian angle, when placed over the map per Zodiac's instructions, pointed to the locations of two Zodiac attacks.[83] On October 7, 1970, the Chronicle received a three-by-five inch card signed by the Zodiac with the and a small cross reportedly drawn with blood. The card's message was formed by pasting words and letters from an edition of the Chronicle, and thirteen holes were punched across the card. Inspectors Armstrong and Toschi agreed that it was "highly probable" that the card had been sent by the Zodiac.[84]

Letter to Paul Avery

The Halloween card addressed to Paul Avery on October 27, 1970

On October 27, 1970, Chronicle reporter Paul Avery (who had been covering the Zodiac case) received a Halloween card signed with a letter 'Z' and the Zodiac's crossed-circle symbol. Handwritten inside the card was the note "Peek-a-boo, you are doomed." The threat was taken seriously and was the subject of a front-page story in the Chronicle.[51] Soon after receiving the letter, Avery received an anonymous letter alerting him to the similarities between the Zodiac's activities and the unsolved murder of Cheri Jo Bates, which had occurred four years earlier at the city college in Riverside in the Greater Los Angeles Area, more than 400 miles (640 km) south of San Francisco.[85] Avery reported his findings in the Chronicle on November 16, 1970.

Final Zodiac letter

After the Lake Tahoe card, the Zodiac remained silent for nearly three years. The Chronicle then received a letter from the Zodiac, postmarked January 29, 1974, praising The Exorcist as "the best saterical comidy [sic] that I have ever seen". The letter included a snippet of verse from The Mikado and an unusual symbol at the bottom that has remained unexplained by researchers. Zodiac concluded the letter with a new score, "Me = 37, SFPD = 0".[86]

Later letters of suspicious authorship

Of further communications sent by the public to members of the news media, some contained similar characteristics of previous Zodiac writings. The Chronicle received a letter postmarked February 14, 1974, informing the editor that the initials for the Symbionese Liberation Army spelled out an Old Norse word meaning "kill".[87] However, the handwriting was not authenticated as the Zodiac's.[88] A letter to the Chronicle, postmarked May 8, 1974 featured a complaint that the movie Badlands was "murder-glorification" and asked the paper to cut its advertisements. Signed only "A citizen", the handwriting, tone, and surface irony were all similar to earlier Zodiac communications.[89] The Chronicle subsequently received an anonymous letter postmarked July 8, 1974, complaining of their publishing the writings of the antifeminist columnist Marco Spinelli. The letter was signed "the Red Phantom (red with rage)". The Zodiac's authorship of this letter is debated.[89] A letter, dated April 24, 1978, was initially deemed authentic but was declared a hoax less than three months later by three experts. Dave Toschi, the SFPD homicide detective who had worked the case since the Stine murder, was thought to have forged the letter. Author Armistead Maupin believed the letter to be similar to "fan mail" that praised the work of Toschi in the investigation, which he received in 1976; he believed both letters were written by Toschi. While he admitted to writing the fan mail, Toschi denied forging the Zodiac letter and was eventually cleared of any charges. The authenticity of this letter remains unverified. On March 3, 2007, an American Greetings Christmas card sent to the Chronicle, postmarked 1990 in Eureka, was re-discovered in their photo files by editorial assistant Daniel King. This letter was handed over to the Vallejo police.[90] Inside the envelope, with the card, was a photocopy of two U.S. Postal keys on a magnet keychain. The handwriting on the envelope resembles Zodiac's print but was declared inauthentic by forensic document examiner Lloyd Cunningham; however, not all Zodiac experts agree with Cunningham's analysis.[91] There is no return address on the envelope nor is his crossed-circle signature to be found. The card itself is unmarked. The Chronicle turned over all the material to the Vallejo Police Department for further analysis.

In his 1976 autobiography, Melvin Belli described an engineered encounter with himself, undercover police officers, and a Riverside law student.[92] The young man had allegedly claimed that he was the Zodiac Killer. Upon meeting the young man face-to-face, Belli decided that they were investigating the wrong man for the Zodiac crimes. In 2002, Robert Graysmith described the possibility that a former student of Pacific High School, in the San Bernardino area, was the source of the Zodiac alias.[93]

21st century developments

In April 2004, the SFPD marked the case "inactive", citing caseload pressure and resource demands, effectively closing the case.[94][95] However, they re-opened their case sometime before March 2007.[6][96] The case is open in Napa County[97] and in the city of Riverside.[98] In May 2018, the Vallejo Police Department announced their intention to attempt to collect the Zodiac Killer's DNA from the back of stamps he used during his correspondence. The analysis, by a private laboratory, was expected to check the DNA against GEDmatch.[99][100] It was hoped the Zodiac Killer may be caught in a similar fashion to the "Golden State Killer" Joseph James DeAngelo. In May 2018, a Vallejo police detective said that results were expected in several weeks. However, as of January 2023, no results have been reported.[101][102][103]

Suspects

Arthur Leigh Allen

Robert Graysmith's book Zodiac advanced Arthur Leigh Allen, who died in 1992, as a potential suspect based on circumstantial evidence. Allen had been interviewed by police from the early days of the Zodiac investigations and was the subject of several search warrants over a 20-year period. In 2007, Graysmith noted that several police detectives described Allen as the most likely suspect.[104] In 2010, Dave Toschi stated that all the evidence against Allen ultimately "turned out to be negative".[105] Toschi's daughter said in 2018 that her father had always thought Allen had been the killer, but they did not have the evidence to prove it. Mark Ruffalo, who portrayed Toschi in the 2007 film Zodiac, commented, "If you get into who these cops were, you realize how they have to take their hunches, their personal beliefs, out of it. Dave Toschi said to me, 'As soon as that guy walked in the door, I knew it was him.' He was sure he had him, but he never had a solid piece of evidence. So he had to keep investigating every other lead."[106] On October 6, 1969, Allen was interviewed by detective John Lynch of the Vallejo Police Department. Allen had been reported in the vicinity of the Lake Berryessa attack against Hartnell and Shepard on September 27, 1969; he described himself scuba diving at Salt Point on the day of the attacks.[107] Allen again came to police attention in 1971 when his friend Donald Cheney reported to police in Manhattan Beach, California, that Allen had spoken of his desire to kill people, used the name Zodiac, and secured a flashlight to a firearm for visibility at night. According to Cheney, this conversation occurred no later than January 1, 1969.[108] Jack Mulanax of the Vallejo Police Department subsequently wrote that Allen had received a dishonorable discharge from the U.S. Navy in 1958 and had been fired from his job as an elementary school teacher in March 1968 after allegations of sexual misconduct with students. He was generally well-regarded by those who knew him, but he was also described as "fixated on young children and angry at women". In September 1972, San Francisco police obtained a search warrant for Allen's residence.[109] In 1974, Allen was arrested for sexually assaulting a 12-year-old boy;[110] he pleaded guilty and served two years imprisonment. Vallejo police served another search warrant at Allen's residence in February 1991.[111] Two days after Allen's death in 1992, Vallejo police served another warrant and seized property from Allen's residence.[112] In July 1992, victim Mike Mageau identified Allen as the man who shot him in 1969 from a photo line-up, saying "That's him! It's the man who shot me!"[113][114] However, police officer Donald Fouke, who is speculated to have seen the Zodiac fleeing from the Stine killing, said in the 2007 documentary His Name Was Arthur Leigh Allen that Allen weighed about 100 pounds more than the man he saw, adding that his face was "too round". Nancy Slover, who received the call from the Zodiac in the aftermath of the Mageau/Ferrin shooting, said that Allen did not sound like the man on the phone.[115] Other evidence existed against Allen, albeit entirely circumstantial. A letter sent to the Riverside Police Department from Bates's killer was typed with a Royal typewriter with an Elite type, the same brand found during the February 1991 search of Allen's residence. He owned and wore a Zodiac brand wristwatch. He lived in Vallejo and worked minutes away from where one of the Zodiac victims (Ferrin) lived and from where one of the killings took place.[36] In 2002, the SFPD developed a partial DNA profile from the saliva on stamps and envelopes of Zodiac's letters. The SFPD compared this partial DNA to that of Arthur Leigh Allen.[116][117] A DNA comparison was also made with the DNA of Don Cheney, who was Allen's former close friend and the first person to suggest Allen may be the Zodiac Killer. Since neither test result indicated a match, Allen and Cheney were excluded as the contributors of the DNA.[118] Retired police handwriting expert Lloyd Cunningham, who worked on the Zodiac case for decades, stated, "They gave me banana boxes full of Allen's writing, and none of his writing even came close to the Zodiac. Nor did DNA extracted from the envelopes (on the Zodiac letters) come close to Arthur Leigh Allen."[4]

Gary Francis Poste

In October 2021, the Case Breakers, claiming to be a team of over 40 cold case investigators composed of former law enforcement investigators, military intelligence officers, and journalists, claimed to have identified the Zodiac Killer as Gary Francis Poste, who died in 2018 at the age of 80 years. The team claimed to have uncovered forensic evidence and photos from Poste's darkroom, and noted that scars on Poste's forehead matched those they said were described on the killer. They also claimed that removing the letters of Poste's name from one of Zodiac's cryptograms revealed an alternate message.[119] The FBI subsequently stated that the case remained open and that there is "no new information to report," while local law enforcement expressed skepticism to the Chronicle regarding the team's findings.[120] Riverside police officer Ryan Railsback said the Case Breakers' claims largely relied on circumstantial evidence,[3][121] and author Tom Voigt, a Zodiac Killer investigator, called the claims "bullshit". Voigt noted that no witnesses in the case described Zodiac as having scars on his forehead.[122]

Other suspects

Unnamed suspects

In 2009, former lawyer Robert Tarbox, who was disbarred in August 1975 by the California Supreme Court for failure to pay some clients, [143] [144] said that in the early 1970s a merchant mariner walked into his office and confessed to him that he was the Zodiac Killer. The seemingly lucid seaman, whose name Tarbox would not reveal based on confidentiality, described his crimes briefly but persuasively enough to convince Tarbox. The man said he was trying to stop himself from his "opportunistic" murder spree but never returned to see Tarbox again. Tarbox took out a full-page ad in the Vallejo Times-Herald that he claimed would clear the name of Arthur Leigh Allen as a killer, his only reason for revealing the story 30 years after the fact. Robert Graysmith, the author of several books on Zodiac, said Tarbox's story was "entirely plausible". said that in the early 1970s a merchant mariner walked into his office and confessed to him that he was the Zodiac Killer.

In 2010, a picture surfaced of known Zodiac victim Darlene Ferrin and an unknown man who closely resembles the composite sketch, formed based on eyewitnesses' descriptions, of the Zodiac Killer. According to America's Most Wanted (February 19, 2011), police believe the photo was taken in San Francisco in the middle of either 1966 or 1967. [145] (February 19, 2011), police believe the photo was taken in San Francisco in the middle of either 1966 or 1967. Sandy Betts is an amateur Zodiac researcher who claims that the people responsible for the Zodiac attacks repeatedly harassed and attacked her.[146][147][148] She states that three men were the primary culprits and that at least one of these core members is identified and still lives in the San Francisco Bay Area.[149] Betts also claims that the primary killer was known as "Tony" and worked in construction. She estimates several dozen fatal Zodiac attacks overall. In her narrative, some elements of Zodiac crimes are theatrical in nature.

Cleared suspects

According to researcher Tom Voigt, fingerprint comparison in February 1989 eliminated 1970s serial killer Ted Bundy as a person of interest in the Zodiac case. [150] as a person of interest in the Zodiac case. Serial killer Edward Edwards , who committed five murders between 1977 and 1996, was linked to the Zodiac murders and several other unsolved cases by former cold case detective John A. Cameron. Cameron's theories were met with "almost universal disdain, especially from law enforcement". [151] , who committed five murders between 1977 and 1996, was linked to the Zodiac murders and several other unsolved cases by former cold case detective John A. Cameron. Cameron's theories were met with "almost universal disdain, especially from law enforcement". Ted Kaczynski , a domestic terrorist and mathematician also known as the Unabomber, was investigated for possible connections to the Zodiac Killer in 1996. Kaczynski worked in northern California at the time of the Zodiac murders and, like the Zodiac, had an interest in cryptography and threatened the press into publishing his communications. [152] Kaczynski was ruled out by both the FBI and SFPD based on fingerprint and handwriting comparison, and by his absence from California on certain dates of known Zodiac activity.

The Manson Family: following the capture of Charles Manson and his murderous cult, a 1970 report by the California Bureau of Criminal Identification and Investigation stated that all male members of the Manson Family had been investigated and eliminated as Zodiac suspects.[153]

Notes

a b Well into the 1970s, the Zodiac wrote letters claiming responsibility for earlier and later killings, but he has never been definitively linked to any crime that took place before 1968 or after 1969. ^ The killer himself used the name the Zodiac and is often simply called Zodiac. ^ paradice, the Z408 message says: I like killing people because it is so much fun. It is more fun than killing wild game in the forest because man is the most dangerous animal of all. To kill something gives me the most thrilling experience. It is even better than getting your rocks off with a girl. The best part of it is that when I die, I will be reborn in paradice and all that I have killed will become my slaves. I will not give you my name because you will try to slow down or stop my collection of slaves for my afterlife. ebeorietemethhpiti When corrected for most errors, excluding the distinctive spelling of, the Z408 message says: ^ [20] Shortly after the decoding of this cipher, Vallejo police contacted a psychiatrist based at the state prison at Vacaville to review the contents. This expert determined the contents were typical of a brooding and isolated individual; the psychiatrist interpreted the author's comparison of the thrill of murder to the satisfaction of sex as "usually an expression of inadequacy" from a male who senses extreme rejection. The fact that the author claimed to be collecting slaves for his afterlife revealed this individual's sense of omnipotence. ^ Fort Scott Tribune that the Zodiac killer lived in the [35] In 1976, Toschi would opine his belief to a reporter from thethat the Zodiac killer lived in the San Francisco Bay area, and that the letters he had sent had been an "ego game" for him, adding: "He's a weekend killer. Why can't he get away Monday through Thursday? Does his job keep him close to home? I would speculate he maybe has a menial job, is well thought of and blends into the crowd ... I think he's quite intelligent and better educated than someone who misspells words as frequently as he does in his letters." ^ paradice, the Z340 message says: I hope you are having lots of fun in trying to catch me. That wasn't me on the TV show, which brings up a point about me. I am not afraid of the gas chamber because it will send me to paradice all the sooner, because I now have enough slaves to work for me where everyone else has nothing when they reach paradice, so they are afraid of death. I am not afraid because I know that my new life is life will be an easy one in paradice death. When corrected for most errors, excluding the distinctive spelling of, the Z340 message says:
