42 year old missing persons case solved... the latest car found in a lake using sonar, why aren't more lakes getting checked?

A 43-year-old mystery was solved Tuesday after authorities found the remains of Amos Shook – missing since 1972 – and identification cards in a 1968 Pontiac Catalina pulled from the bottom of Lake Rhodhiss in Caldwell County.

The green Catalina, filled with mud with the roof caved in, matched the car belonging to Shook on Feb. 19, 1972, when he was reported missing, Caldwell County Sheriff’s Capt. B.J. Fore said Wednesday. “This case was so old we didn’t even have a report on it,” Fore said.

Sheriff Alan Jones said Shook’s wallet was found in the car with remarkably preserved identification cards.

The search for Shook, an Air Force veteran, was resumed after decades when his daughter approached Jones and investigators last month with a newspaper article about her missing father and asked them to search again.

Using advanced sonar from the North Catawba Fire and Rescue Dive Team, the outline of a car was spotted under 30 feet of water, Fore said.
