Zodiac Killer
The Zodiac Killer is the pseudonym of a serial killer who operated in Northern California in the late 1960s. The case has been described as the most famous unsolved murder case in American history, becoming a fixture of popular culture and inspiring amateur detectives to attempt to resolve 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, and his known attacks took place in Benicia, Vallejo, unincorporated Napa County, and the city of San Francisco proper. Two of his attempted victims survived. The Zodiac himself claimed to have murdered 37 victims, and he has been linked to several other cold cases, some in Southern California or outside the state.
