Zerilli, 85, convicted multiple times of involvement organized crime and most recently released from prison in 2008, was behind bars when Hoffa disappeared on July 30, 1975.

He told WDIV other mafia leaders told him Hoffa would be buried in a barn off Buell Road in northern Oakland County.

WDIV aired images of a large empty field identified by Zerilli as the burial location.

Zerilli said he's been interviewed three times by FBI agents and that he believes they have enough information to obtain a search warrant.

“I’ve answered everything they have asked me I’ve answered, I haven’t refused to answer one thing that they ask,” he said.

A search there would be one of many Detroit-area digs for the remains of the iconic union boss in recent years.

Authorities in September took soil samples from underneath a shed behind a Roseville home after receiving a tip from a man who claimed he saw the body buried there in 1975.

That search came up empty, as have so many over the years.

Zerilli's tip comes as he promotes a book called "Hoffa Found," according to the Associated Press.
