The Zodiac Killer is the name of an unidentified serial killer who made his mark in the cities of Benicia, Vallejo, Napa County and San Francisco, California between December 1968 and October 1969. The killer claimed to have killed 37 people in his cryptic and taunting letters he sent to local newspapers. There were only seven victims confirmed: four men and three women. Two men survived his attempted murder. Throughout the years, many people have claimed to know the true identity of the killer. However, those claims were unsuccessful. Now, another man has stepped up, claiming to be the son of The Zodiac Killer.
