- Full Episode
Throughout the 1960s and 70s, from Los Angeles to San Francisco, Californians were terrorized by multiple killers including notorious serial killers like the Zodiac Killer, the Hillside Stranglers, Herbert Mullin, and Ed Kemper. While the decade may have ended with these killers disappearing or apprehended, the threat of violence and murder simply moved north.
Though less known than his contemporaries, David Carpenter was no less prolific and frightening a killer than those men mentioned above. Nicknamed “The Trailside Killer” by the press, Carpenter terrorized Point Reyes and Santa Cruz County for a decade, assaulting, kidnapping, and killing at least eight people, but he was suspected of more. Like those other killers, Carpenter had a long history of violent and antisocial behavior going back to his childhood, including multiple arrests and incarcerations. How was it that a man with such an alarming history of violence could go uncaught for a decade?
