Beachgoers usually dread riptides and rainy days, but from 1974 to 1983, a different fear gripped the New Jersey Shore: young women were disappearing. Their abductor was Richard Biegenwald, a man released for good behavior after serving seventeen years in prison for murder and spending time in a psychiatric facility. Police arrested him on suspicion of rape, and it was not until they connected him to a woman's death in Asbury Park that he finally stopped his rampage. Investigators later linked him to nine murders and convicted him of five. Former New Jersey state trooper John O'Rourke narrates the chilling story of the Jersey Shore Thrill Killer.
