Legendary Teamsters boss Jimmy Hoffa disappeared in 1975 and the FBI has never been able to turn up a single clue as to where his body might be buried (theories have ranged from chopped into pieces and dumped in Lake Michigan to buried in Giant Stadium). Now the feds are digging up a farm just 15 miles away from where he disappeared.

Reuters reports:

The FBI, acting on a tip about the mysterious 1975 disappearance of labor union leader Jimmy Hoffa, dug on a Michigan horse farm Wednesday in search of evidence in the case.

Overhead video images from a Detroit television station showed agents using shovels to dig on a farm in Milford Township, 35 miles from Detroit. The farm is about 15 miles west of the restaurant parking lot where the legendary Teamsters boss went missing.

The FBI could not be reached for comment, but the Detroit Free Press quoted Oakland County Prosecutor David Gorcyca as saying the FBI had a promising tip in the case.

Hoffa was declared dead in 1982, and numerous books and movies about his life have pinned his disappearance on mobsters who murdered him and disposed of his body because they did not want him back in charge of the Teamsters.
