A Tennessee man has died after a cave collapsed in western Kentucky while he was digging for Native American artifacts.

Christian County Coroner Dorris Lamb says 42-year-old Devin William Peters, of Clarksville, Tenn., was killed in the accident.

Christian County Rescue Team director Randy Graham told the Kentucky New Era that Peters and another man were at the cave, located between Pembroke and Oak Grove, when the walls of an excavation trench collapsed.

The second man was above ground and telephoned for help at 4 p.m. CST Monday.

Graham said Peters' remains were found eight feet below the floor of the cave, buried under about four feet of dirt. Graham said the remains were removed about four hours after the collapse.
