Wildlife agents from the state Department of Natural Resources were using boats and divers Friday to search the Edisto River in Dorchester County for the body of a 67-year-old St. George man who is presumed to have drowned, said DNR Lt. Robert McCullough.

The Dorchester County Sheriff’s Office was monitoring the situation, said sheriff’s Maj. John Garrison. The missing man’s pickup truck was parked along the river at a boat landing off Mulberry Road, Garrison said. The search began Thursday night, but was hindered by severe thunderstorms.
