CHATTANOOGA, Tenn. — Earlier this week, Bradley County Sheriff's Department investigators enlisted the help of Tennessee wildlife resource officers to try to find a submerged car in Parksville Lake in Polk County, Tenn.
Bradley County Sgt. Bill Coultry said the side-scan sonar Tennessee Wildlife Resources Agency Officers Joe Bush and Ken Ripley used in the search was an invaluable tool to peer 50 feet into the water.
