Authorities Drill Into Michigan Driveway In Search Of Hoffa Remains

ROSEVILLE, MI - SEPTEMBER 28: Media and onlookers watch police drill through a concrete driveway to obtain a soil sample that will be tested for signs of human decomposition at a site where a tipster reported that the body of former Teamster's union boss Jimmy Hoffa may be buried September 28, 2012 in Roseville, Michigan. Ground-penetrating radar indicated there is an anomaly under the concrete. The former Teamster's president disappeared from a restaurant parking lot in Bloomfield Township, Michigan in 1975.
