SERIAL KILLER: Zodiac Killer

In December 1968, two teenagers were shot and killed on Lake Herman Road in Benicia, California, in the first confirmed attack attributed to the Zodiac Killer, an unidentified assailant who went on to murder at least four more people across the San Francisco Bay Area and taunt investigators with coded letters and ciphers for decades. The Zodiac named himself in print, claimed a victim count that was never verified, and was never identified or arrested. The Z340 cipher was solved in 2020, but the Z13 cipher, believed to encode the killer's name, remains unsolved, and no confirmed DNA match has ever been made.

Anyone with information about the Zodiac killings in the San Francisco Bay Area is urged to contact the Vallejo Police Department at 707-648-4218 or the San Francisco Police Department cold case unit at 415-575-4444.
