The latest search for Teamster boss Jimmy Hoffa's remains turned up empty once again, but now a source close to law enforcement is claiming that Anthony “Tony Pro” Provenzano killed Hoffa and fed his body to a wood chipper. Provenzano was once an esteemed member of the Genovese crime family who was connected to labor unions like the Teamsters. In the 38 years since his disappearance, it's been rumored that Hoffa was killed by the Detroit mob, who didn't want him leading the union again.
Hoffa was last seen outside of the Red Fox restaurant on the outskirts of Detroit in July 1975; he was reportedly supposed to meet Provenzano and Detroit mobster Anthony Giacolone. Hoffa's body (or what's left of it) will probably never be found, but how long before another theory arises?
