On this day, July 30, in 1975, Jimmy Hoffa disappeared from a restaurant parking lot in suburban Detroit. He has not been seen or heard from since.
Hoffa, 62, had been the powerful head of the Teamsters union despite spending the last four years of his term in prison for jury tampering and attempted bribery. His 15-year sentence was commuted by President Nixon in 1971, with the agreement that he step down from the union.
In 1975, while trying to regain power in the Teamsters, he vanished outside the Machus Red Fox Restaurant in Bloomfield Township, Mich.
Hoffa was expecting to meet two high-ranking Mafia leaders that day. He was declared legally dead in 1982. - Scott McCabe
