Overview
The Zodiac Killer case concerns a string of confirmed attacks in Northern California in the late 1960s, including the murders of five victims, along with a campaign of letters and ciphers sent to police and the press. Some of the ciphers were decoded decades later, but the killer's identity has never been established, keeping the case among America's most famous unsolved homicide investigations.
