Theron Campbell, 77, disappeared from his rural home on U.S. Highway 10 near St. Cloud, Minnesota, on October 27, 1972. He was last seen at his residence about 6:30 p.m. that evening. Campbell lived alone and had no close relatives nearby; his car remained at the house when he vanished.

A stripped, stolen vehicle was later found abandoned near Campbell’s home, but it is unclear whether that vehicle was connected to his disappearance. At the time he went missing he was described as a Caucasian male, 5 feet 11 inches, about 185 pounds, with gray hair and brown eyes, possibly wearing work clothes, a brown jacket and a dark-colored topcoat. Foul play is suspected, but despite investigation the case produced few leads and remains unsolved.

Anyone who knew Theron Campbell, his routines, or who lived along U.S. Highway 10 near St. Cloud in 1972 is asked to share information that might help resolve this long-open disappearance.
