ANDERSON (AP) ó Authorities said a 9-year-old and a 5-month-old boy have died after a boat capsized on Lake Hartwell.

The Anderson County Coronerís Office told local media outlets that the older boy, Christian Henderson, was pulled from the water and could not be resuscitated, while divers found the baby, Timothy Dragoo, about four hours after the boat flipped. Neither child was wearing a life jacket.

Department of Natural Resources spokesman Robert McCullough said the pontoon boat was pulling into a dock on the lake near Interstate 85 around 8:30 p.m. Sunday when it turned over. Witnesses said there were about a dozen people on board.

DNR agents charged the boatís driver, 52-year-old Dawn Thompson, with driving under the influence resulting in death. It wasnít known if she had a lawyer.
