COLLETON COUNTY, S.C. (WCBD) – Three people were killed and several others injured during a multi-vehicle crash on I-95 in Colleton County earlier Sunday.

Colleton County Fire Chief Barry McRoy said fire-rescue crews responded to the crash near mile marker 53 around 4:45 p.m.

Five cars and a small bus were involved in the collision; two of the involved vehicles caught fire.

According to Chief McRoy, three people – who appeared to be a male, female and teenager – were trapped inside one of the vehicles. All three died at the scene.

“Several bystanders attempted to rescue the three people from the burning car. One was an Army Sgt., who sustained minor burns during the attempt. He refused ambulance transport to a hospital,” officials said.

Seven others, including several children, were taken to area hospitals. Chief McRoy said six people were taken by ambulance while a 17-year-old woman was airlifted to Trident Medical Center in North Charleston.

All southbound lanes of I-95 were closed for several hours and reopened around 10:30 p.m. Walterboro Police and Colleton County Sheriff’s deputies assisted with a traffic detour.

The crash is under investigation by the South Carolina Highway Patrol.
