Local officials in North Carolina say the body of a fourth tuber has been found in a river following a deadly accident in which a family on a recreational float went over a dam. The Rockingham County Sheriff’s Office confirmed in a news release Sunday that 7-year-old Isiah Crawford was the person who was found in the Dan River. The search continued for the last remaining tuber, 35-year-old Teresa Villano. The accident occurred Wednesday night when a group of nine people floated down the river on inflatable tubes and went over a dam. Four people were rescued Thursday, while three tubers’ bodies were found that day. Experts say that low-head dams are known for trapping people in a powerful current.EDEN, N.C.
