Jimmy Hoffa Disappearance

On July 30, 1975, Teamsters President Jimmy Hoffa — possibly the most powerful labor leader in American history — went to a restaurant in suburban Detroit to meet two Mafia figures and was never seen again. The FBI has investigated for 50 years, excavated multiple locations (including under Giants Stadium in New Jersey — he wasn't there), and interviewed hundreds of mobsters. The leading theory: he was killed by the Mafia to prevent him from reclaiming the Teamsters presidency, which organized crime controlled. His body has never been found. He was declared legally dead in 1982. The phrase "buried next to Hoffa" entered American slang.
