RICHLAND, Wash. — Benton County Coroner Rick Corson has asked a forensic anthropologist to help determine the age and origin of a bone found in the Columbia River.

The lower jaw and two teeth were found by a boater Saturday in a couple of inches of water on the shore north of Richland.

The bones are being sent to the state Department of Archaeological and Historic Preservation in Olympia for evaluation.

Corson says the site where the bone was found has been marked with GPS, and investigators won’t disturb it until they know whether the bones are from a Native American.

In 1996 a prehistoric skeleton known as Kennewick Man was found in the Columbia near Kennewick.
