(CNN) — The FBI is planning to dig in a Detroit-area field Monday in a hunt for the remains of former Teamsters boss Jimmy Hoffa, according to a law enforcement source with direct knowledge of the investigation.
Agents on Monday morning were executing a search warrant for a field in Oakland Township, north of Detroit, based in part on information provided by Tony Zerilli, a man alleged to have been a mobster.
