James Riddle Hoffa, 62, was last seen on July 30, 1975, in Bloomfield Township, Michigan. He told his family he was headed to the Machus Red Fox restaurant for a 2:00 p.m. appointment with Anthony Tony Jack Giacalone and Anthony Tony Pro Provenzano. At about 2:15 p.m. Hoffa called his wife, Josephine, from a payphone to say the men had not arrived; that was the last known contact.

Hoffa’s unlocked car was found in the restaurant parking lot the next morning with no sign of him. The FBI investigated, the family offered a reward, and searches have been conducted at sites including an Oakland Township field and a former New Jersey landfill, but his remains have never been found. In 1982 he was declared legally dead. Reports say investigators and the public have widely believed his disappearance was connected to his efforts to regain power in the Teamsters and that the prevailing view is he was murdered by the Mafia, though the case remains officially unsolved.
