It operated in Northern California in the late 1960s and early 1970s. The killer got the name "Zodiac" because in all the letters he sent to the local Bay Area press there were four cryptograms and only one was completely solved. Police investigated more than 2,500 potential suspects, but the case was never officially solved. While there were a few suspects who stood out, the technology of the time was not advanced enough to single out just one of the alleged killers. Numerous suspects have been named by law enforcement, but no conclusive evidence has emerged and "The Zodiac Killer" still remains unknown. In April 2004, the San Francisco Police Department marked the case as "inactive", but reopened the case in 2007. The case also remains open in the city of Vallejo, Napa County, and Solano County. a gruesome series of murders threw the population of San Francisco into panic. For years the Zodiac has been provoking the police with strange codes, phone calls and cryptic messages. Before it was all over, this cunning assassin changed the lives of eight people, of which only two survived to tell the tale. The Zodiac claimed thirty-seven murders in letters to newspapers, investigators agree on only seven confirmed victims, two of whom survived.

Paul Lee Stine, age twenty-nine, was shot and killed on October 11, 1969. Suspected victims: Robert Domingos, age eighteen, and Linda Edwards, seventeen: shot and killed on June 4, 1963. Both they were possible victims of the Zodiac due to the similarities between their attack and the Zodiac's attack. Cheri Jo Bates, eighteen: stabbed to death and nearly decapitated on October 30, 1966. Bates' possible connection to the Zodiac did not appear until four years after her murder, when a San Francisco Chronicle reporter received a tip.
