Accident or Not? I don’t think this was accidental. CONWAY, S.C. – Two people being transported in a sheriff’s office van in South Carolina died Tuesday when the vehicle was overcome by floodwaters, the Horry County Sheriff's Office confirmed. The vehicle, staffed by two Horry County deputies, was transporting two detainees from Conway to Darlington and was traveling west on Highway 76 around a half mile from the Little Pee Dee River when the vehicle was overtaken by flooding from Hurricane Florence, according to an emailed statement from the sheriff's office. The two deputies "attempted to extricate the persons being transported," the agency said in its statement. The Associated Press reported the detainees were two women. Their names have not been released.

High-water rescue teams arrived and were able to rescue the two deputies from the top of the van, according to the statement. "At this time, the recovery effort is ongoing, and the transportation vehicle cannot be removed due to rising waters and dangerous conditions," the sheriff's office said.
