Pam Jackson and Sherri Miller

On a warm spring night in 1971, two teenagers set out for a party in rural South Dakota, never to be seen again. Their families grew frantic, but law enforcement dismissed their disappearance as teenage rebellion. For decades, the case was plagued by missteps, false leads, and a suspect who was ultimately cleared. Then, in 2013, a state agent retracing the girls’ route spotted the undercarriage of a car beneath a bridge near Brule Creek. Inside were the girls’ belongings—and their remains. After 42 years of mystery, the truth emerged and the discovery brought a haunting reminder of how close the answers had always been.
