Notorious labor union leader Jimmy Hoffa had for decades been a polarizing figure, with his ties to organized crime investigated as early as 1957 by future U.S. Attorney General Bobby Kennedy. A jury tampering conviction eventually took him out of official power, but Hoffa worked tirelessly behind the scenes to reclaim his position -- until his disappearance in 1975. Despite countless theories about what happened to him, Hoffa's fate remains one of the most infamous unsolved mysteries in American history.  "Crimes of the Centuries" is a podcast from Grab Bag Collab exploring forgotten crimes from times past that made a mark and helped change history.
