It's one of the most famous mysteries. What happened to former Teamsters boss Jimmy Hoffa?
Well, a new book claims Hoffa is buried underneath the General Motors Headquarters in Detroit.
Hoffa's former driver-turned police informant Marvin Elkind co-authored the book "The Weasel: A Double Life in the Mob".
In it, he claims he learned where Hoffa was buried during a Teamsters Conference in Detroit in 1985.
Hoffa vanished in 1975 while reportedly on his way to meet some mafia figures.
He was declared legally dead in 1982, but his body has never been found despite numerous theories about where it could be buried.
