SMITHVILLE — The investigation into a Nashville heart surgeon who disappeared on a Middle Tennessee lake is still being treated as a missing person case, authorities said.
Dr. William Coltharp vanished Oct. 2 while kayaking on Center Hill Lake about 60 miles east of Nashville.
Last week, authorities recovered Coltharp’s kayak with a life jacket and laptop computer inside. The computer has been sent to the Tennessee Bureau of Investigation to see if any data could be recovered, WSMV-TV reported (http://bit.ly/o3lvVB ).
Coltharp was a standout defensive football player at Mississippi State University.
DeKalb County Sheriff Patrick Ray said Monday that witnesses saw a man matching Coltharp’s description load a cinder block into the kayak before paddling onto the lake.
Authorities said a cadaver dog hit on something Saturday, but it turned out to be nothing.
Some water in that area of the lake is up to 130 feet deep and difficult to search Tennessee Wildlife Resources Agency officer Nick Luper told The Tennessean newspaper.
Authorities said that Coldtharp told his wife he would be home in time for dinner. She called emergency officials when he hadn’t arrived by 1 a.m.
Coltharp is a native of New Albany. He was a standout football player at Mississippi State.
Coltharp was honored in 1998 as a College and School Alumni of the Year at Mississippi State.
