Who is the Zodiac Killer?

The Zodiac Killer is the pseudonym of an unidentified serial killer, who operated in Northern California in the late 1960s. 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.

A Series of Unsolved Murders

The Zodiac Killer’s known crimes include at least five confirmed murders:

1. David Faraday and Betty Lou Jensen: On December 20, 1968, the Zodiac Killer shot and killed these two young individuals near Lake Herman Road in Benicia, California.
2. Michael Mageau and Darlene Ferrin: On July 4, 1969, the Zodiac Killer attacked a parked car in a remote area near Vallejo, California, shooting both occupants. Michael Mageau survived, but Darlene Ferrin died as a result of the attack.
3. Bryan Hartnell and Cecelia Shepard: On September 27, 1969, the Zodiac Killer approached this young couple near Lake Berryessa and bound them before stabbing them. Bryan Hartnell survived the attack but Cecelia Shepard died.
4. Paul Stine: On October 11, 1969, the Zodiac Killer fatally shot a taxi driver named Paul Stine in San Francisco.
5. The Zodiac Killer is also suspected of killing two other people: Donna Lass in 1970 and Cheri Jo Bates in 1966. However, there is not as much evidence linking him to these murders.

The Cryptic Letters

The Zodiac’s Mysterious Letters

The Zodiac Killer’s letter-writing campaign began with the double murder of David Faraday and Betty Lou Jensen in 1968. Following the crime, the killer sent a letter to the Vallejo Times-Herald, claiming responsibility for the murders and including a cipher designed to be decoded. The letters exhibited a mix of arrogance, taunts, and a craving for public attention. The Zodiac Killer often referred to himself as the “Zodiac” and included cryptic symbols as his signature. One of the most eerie aspects of these letters was the Zodiac’s demand that they be published in the newspapers or else he would commit more murders.

The first major breakthrough in the case came with the deciphering of the 408-symbol cryptogram sent on July 31, 1969, to the San Francisco Chronicle. This cipher revealed a disturbing message but offered no concrete clues to the killer’s identity. The 340-symbol cryptogram, sent in a letter dated November 8, 1969, was particularly perplexing and remained unsolved for decades.

Cryptograms and Ciphers

Within these letters lay the true puzzle—the cryptograms and ciphers that the Zodiac Killer challenged the public to decode. These ciphers were designed to both taunt investigators and leave a lasting mark on the public psyche. The Zodiac Killer’s cryptograms were of particular interest to amateur codebreakers and professional cryptanalysts alike. The most famous of these cryptograms was the 408-symbol cipher, sent to the San Francisco Chronicle on July 31, 1969. Published in the newspaper, it sparked immediate public interest and efforts to decode its hidden message.

Ultimately, it was a schoolteacher and his wife, Donald and Bettye Harden, who cracked the code, revealing a message filled with disturbing content but no concrete clues to the killer’s identity. Another significant cipher, the 340-symbol cryptogram, arrived with a letter dated November 8, 1969, addressed to the San Francisco Chronicle and two other newspapers. This cipher remained unsolved for decades, capturing the imagination of codebreakers around the world.

Suspects and Theories

Key Suspects in the Zodiac Killer Case

The Zodiac Killer case has multiple potential suspects and persons of interest, with Arthur Leigh Allen suggested by Robert Graysmith’s book “Zodiac” based on circumstantial evidence. Allen had been interviewed by police since the early days of the Zodiac investigations and was the subject of search warrants. However, in 2010, all the evidence against Allen turned out to be negative. Gary Francis Poste, who died in 2018, was identified by the Case Breakers in 2021, citing forensic evidence and photos from his darkroom. However, law enforcement expressed skepticism and the FBI stated that there was no new information to report.

Other suspects were considered based on circumstantial evidence, fingerprint, handwriting analysis, and DNA testing. Ted Bundy, Edward Edwards, and Ted Kaczynski were investigated but eliminated as suspects through fingerprint and handwriting comparison or alibi. The Manson Family members were also ruled out as Zodiac suspects. The case highlights the complexity of the Zodiac Killer case, with multiple potential suspects and theories, but no definitive resolution as to the killer’s identity.
