Matt Thomas Amon, 20, was last seen August 11, 1971, in Pocatello, Idaho after spending several weeks in the Bannock County Jail following a July arrest for disorderly conduct. He disappeared shortly after his release and no one reported contact with him afterward until the case surfaced decades later.

Described as a 5 feet 9 inches Caucasian male with black hair, a receding hairline, brown eyes and a noticeable scar on his forehead, Matt reportedly associated with a rough crowd and was alleged to have had connections to heroin use. Investigators note fingerprints and DNA exist for him, but the long delay in reporting and sparse details about his last days have left the case with few solid leads.

The Pocatello Police Department continues to investigate. If anyone knew Matt, his whereabouts in August 1971, or has information about his last movements, please come forward.
