KNOXVILLE, Tenn. (AP) -- A specialist in underwater searches will aid the LaFollette Rescue Squad in the search for the body of an Ohio man in Norris Lake.
Peter Gruber of Glendale, Ohio, was riding in a boat running at about 35 miles per hour when he jumped overboard two weeks ago. He never resurfaced.
Gene Ralston of Ralston and Associates, based in Idaho, arrived in LaFollette Sunday afternoon.
Rescue squad spokesman Durand Carmany said Ralston has been shown the area of the lake where Gruber disappeared on May 25.
The company Web site says Ralston uses a side sonar scan system that has helped find the remains of at least 54 people since 1999.
The company is a biological consulting firm.
