The body pulled from the Broad River by recovery teams was identified Monday as Fernando Cardenas-Rodriguez, 24, of San Felipe, Mexico.
Richland County Coroner Gary Watts said the death was ruled a drowning.
Officials did not publicly identify Cardenas-Rodriguez until Monday, because they had to notify relatives in Mexico first. San Felipe is in Baja, Calif.
Cardenas-Rodriguez was working construction near the river Saturday, when he and fellow workers decided to cool off in the river, said S.C. Department of Natural Resources spokesman Lt. Robert McCullough.

“There are some deep holes out there, and he apparently stepped in one,” McCullough said.
His body was found by sheriff’s divers in about 14 feet of water Sunday.
