Jimmy Hoffa
He was declared legally dead in 1982. His disappearance gave rise to many theories as to what happened to him. Most theories believe that Hoffa was lured away and murdered by his enemies in the Mafia, who then found a way to get rid of his body. Examples of how this could have been done include taking it to a crematorium the Mafia owned or burying it in a hidden place. James Buccellato, an expert on crime, says it is unlikely the body was moved a long distance.
