LUKE: So who are you gonna go find now?
LUKE: How about Jimmy Hoffa? That’ll keep you busy for a while.
James “Jimmy” Hoffa (1913-1975) was an American union leader who was President of the International Brotherhood of Teamsters from 1958 to 1971. He had links with organised crime, and was accused of jury tampering, attempted bribery, and fraud in 1964. He was imprisoned in 1967, and released in 1971 after being pardoned by President Richard Nixon in exchange for his resignation from the union presidency; he was barred from union activities until 1980.
Jimmy Hoffa vanished in 1975 while on his way to meet two Mafia leaders, and was declared legally dead in 1982. Several people have come forward saying that they know where Hoffa’s body is, or even claiming to have killed him, but their evidence hasn’t been corroborated, or their testimony unable to be proven. The FBI believe that Hoffa was murdered by the Mafia, but the case remains open.
