Zodiac Killer
(20th century – fl. 1968/fl. 1969)
The Zodiac Killer was a serial killer who operated in Northern California from at least the late 1960s to the early 1970s. His identity remains unknown.

The name was coined in a series of taunting letters sent to the press until 1974. Despite his astrology-related penname the killer hadn't shown any clear interest in astrology, and it's possible he drew inspiration from previous killers such as Jack the Ripper. These letters included four cryptograms or ciphers, three of which have yet to be solved.
