The feds will search for a shallow grave in the exact spot where a reputed former gangster told NBC that Hoffa was buried.
In an exclusive interview in January, Tony Zerilli, alleged to be the former underboss of Detroit's biggest crime family and a main character in Hoffa's disappearance, broke his silence to NBC 4 New York after decades of refusing to answer anyone's questions.
Zerilli told NBC 4 New York that the union leader was buried in a field in suburban Detroit -- about 20 miles north of the restaurant where he was last seen. That's where feds are planning to move earth Monday.
Federal authorities would not be searching that field unless Zerilli, 85 and barely able to walk, came forward with his claim in January, investigators say.
