William Thomas Smith, 52, disappeared from Minnetonka, Minnesota, on January 24, 1977, after the body of his estranged wife, Joan Fields, was found shot to death in a local motel. Investigators focused on Smith when he could not be located; his car was later found abandoned in Iowa, indicating he had left the state. That vehicle was the last confirmed trace of his movements.

Descriptions of Smith note neat, orderly habits and casual work clothing; he enjoyed square dancing and bridge and had worked as a bus driver and in sales, shipping and receiving. Over the years investigators followed sightings and leads in other states, but none produced his capture. The case remains open and unresolved.

If anyone knew William Smith’s whereabouts after January 24, 1977, or has information about that abandoned vehicle in Iowa, please come forward.
