The Zodiac Killer is an unidentified serial killer known to have murdered at least five people in Northern California from late 1968 to late 1969.
Confirmed Attacks
Five murders and two attempted murders have been confirmed by investigators as Zodiac Killer attacks:
-David Faraday (17) and Betty Lou Jensen (16), shot and killed on a remote road in Benicia, CA, in December 1968.
-Darlene Ferrin (22) and Mike Mageau (19), shot in July 1969 in a remote parking lot in Vallejo, CA. Mageau survived.
-Cecelia Shepard (22) and Bryan Hartnell (20), stabbed in September 1969 on the shore of Lake Berryessa in Napa County, CA. Hartnell survived.
-Paul Stine (29), taxi driver fatally shot by his passenger in San Francisco’s Presidio Heights neighborhood in October 1969.
Letters and Cryptograms
Between 1969 and 1974, the killer sent letters to police and newspapers to demand media coverage and take credit for the murders. They often began with the line “This is the Zodiac speaking,” leading to the use of the Zodiac pseudonym. Notable inclusions in these letters were four cryptograms, two of which have been solved, and the symbol resembling gunsight crosshairs that served as the Zodiac’s signature. Through these letters, the Zodiac claimed to have killed as many as 37 people.
Numerous other letters, cards, phone calls, and even murders are believed to be the Zodiac’s work, but are not confirmed. The cryptic nature of the killer’s communications, along with copycat correspondences and attacks, have further complicated the search for answers.
Theories
Multiple suspects have been put forward as the potential Zodiac Killer, though only one was officially named as a suspect by police. Unfortunately, none have ever been charged, and the case remains unsolved. The coded messages, taunting letters, and highly publicized nature of the case have since made the Zodiac Killer a fixture in popular culture.
