David Arthur Faraday, 17, and Betty Lou Jensen, 16, were shot and killed on December 20, 1968, on Lake Herman Road, within the city limits of Benicia.Murders and correspondence Confirmed murdersĪlthough 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. The California Department of Justice has maintained an open case file on the Zodiac murders since 1969. The case also remains open in the city of Vallejo, as well as in Napa and Solano counties. The San Francisco Police Department marked the case 'inactive' in April 2004, but re-opened it at some point prior to March 2007. While many theories regarding the identity of the killer have been suggested, the only suspect authorities ever publicly named was Arthur Leigh Allen, a former elementary school teacher and convicted sex offender who died in 1992.Īlthough the Zodiac ceased written communications around 1974, the unusual nature of the case led to international interest that has been sustained throughout the years. Of the four ciphers he produced, two remain unsolved, and one was cracked only in 2020. Some of the letters included cryptograms, or ciphers, in which the killer claimed that he was collecting his victims as slaves for the afterlife. 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. He has been linked to several other cold cases, some in Southern California or outside the state. The Zodiac claimed to have murdered 37 victims. His known attacks took place in Benicia, Vallejo, unincorporated Napa County, and the city of San Francisco proper. He targeted young couples and a lone male cab driver. 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. It became a fixture of popular culture and has inspired numerous amateur detectives to attempt to solve it. The case has been described as the most famous unsolved murder case in American history.

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