Roseville Police Chief James Berlin says his office is "not claiming it's Jimmy Hoffa" but is "investigating a body that may be at the location."
The union boss was last seen outside a suburban Detroit restaurant on July 30, 1975. Rumors about the location of his body — from now-demolished Giants Stadium to a Michigan horse farm — have been rampant ever since.
Berlin says state environmental officials last week found "an anomaly" while using radar to check the driveway. A soil sample will be taken Friday and tested at Michigan State University for human decomposition.
