Could Jimmy Hoffa be buried in Oakland County?
A man who believes he knows where Jimmy Hoffa was buried says he's been interviewed three times by federal authorities since stepping forward in January.
Tony Zerilli tells Detroit TV station WDIV that the FBI has enough information for a search warrant to dig in Oakland County. He says he answered every question from agents and prosecutors.
The FBI declined to comment Monday.
Zerilli was convicted of organized crime as a reputed Mafia captain. He was in prison in 1975 when Hoffa disappeared from a Detroit-area restaurant but says he was informed about Hoffa's whereabouts after his release.
Hoffa was president of the Teamsters union until 1971. Zerilli has been promoting a book, "Hoffa Found." A website says the book will reveal details about Hoffa's death.
