EDISON - Police in Michigan are planning to take soil samples from beneath a suburban Detroit driveway in an effort to locate missing Teamsters leader Jimmy Hoffa.

A man claims he witnessed Hoffa being buried in that spot about 35 years ago.

The union boss was last seen outside a suburban Detroit restaurant on July 30, 1975.

Rumors about the location of his body have run rampant ever since.

Hoffa has been rumored to be buried everywhere from a Michigan horse farm to the now-demolished Giants Stadium.

A soil sample will be taken on Friday and tested at Michigan State University for human decomposition.
