OAKLAND TOWNSHIP, Mich. - Authorities are digging at a site in Michigan's Oakland Township in search of missing Teamsters boss Jimmy Hoffa.
The FBI and Oakland County Sheriff's Department held a brief news conference Monday morning to provide an update on the dig.
Investigators would only say that a search warrant had been issued in the case. Details of that search warrant are sealed.
No other additional details were released.
In January, KJRH's Detroit station (WXYZ) learned the dig site is near land once owned by suspected mobsters. The land is east of Adams Road and north of Buell Road in Oakland Township.
Land records were uncovered that show suspected mob boss Jack Tocco and his family once owned property in the same area where Anthony Joseph Zerilli claims Hoffa is buried.
The FBI says Zerilli was second in command of the local Detroit mob at one time. Zerilli was in prison at the time Hoffa disappeared but experts say his mob ties give him some credibility.

In 1972 suspected mob boss Jack Tocco and his family members bought 45 acres of land in the area. The Toccos then moved their ownership into a family business and developed homes on that site on two to five acres each.
Hoffa went missing in 1975.
