Leslee Larson was 20 when she disappeared on June 10, 1975, during a mushroom-picking trip near Little Prickly Pear Creek in Wolf Creek, Montana. Her husband, Dennis Larson, told authorities she slipped into the swollen creek and was swept under a fallen log; despite an extensive search no body was recovered and she was presumed drowned.

Family members questioned Dennis’s account from the start. Investigators noted inconsistencies, including that Dennis’s clothes were dry when he reported the incident, which contradicted his claim that he had tried to rescue her. Dennis went on to remarry twice; his third wife, Kathy Frost Larson, was later killed in 1987 when Dennis pushed her off a cliff in Maine, an act that prompted authorities to reopen Leslee’s case.

While serving time for Kathy’s murder, Dennis confessed in 2000 to intentionally pushing Leslee into the creek and was charged with her murder. He died by suicide in prison in 2001 before trial. Leslee’s body has never been found and the case remains open. Did anyone in the Wolf Creek area know the Larsons or remember that day in 1975?
