Hoffa History

Teamster boss Jimmy Hoffa was last seen July 30th 1975 at the Machus Red Fox Restaurant which once stood on the corner of Maple Road and Telegraph Road in Bloomfield Hills.

Hoffa was there to meet two people, a member of the Detroit mafia and a member of the New Jersey mafia.

The meeting never happened and Hoffa was never seen again.

The FBI 35 plus year investigation leads them to believe Jimmy Hoffa was abducted and killed as part of a mafia hit.  

Zerilli has come forward telling his story to the FBI and in 37 years no one this close to the plot has cooperated, until now.
