One person died and three were injured Tuesday night when a Colleton County deputy sheriff's cruiser collided head-on with a pickup truck in Green Pond, authorities said.

The crash occurred around 6:20 p.m. at the intersection of Green Pond Highway and Clover Hill Road, said Sid Gaulden, press officer for the state Department of Public Safety.

Jacob Wright, 19, of Green Pond, died at the scene from head and neck injuries, Colleton County Coroner Rich Harvey said. Wright was a passenger in the truck, which was driven by his father, Jake Wright, 47, authorities said.

Jake Wright and Deputy Scott L. McCoy, 27, were flown to Medical University Hospital for treatment, Gaulden said.

Jake Wright has been discharged from the hospital, said Sharlene Atkins, a hospital spokeswoman. The hospital had no information to release on McCoy's condition, she said.

A boy who was riding in the pickup truck also was injured, Gaulden said. He was taken to the Colleton County Regional Medical Center for treatment. Details on his identity and condition were not available Wednesday, Gaulden said.

A specialized accident-investigation team from the S.C. Highway Patrol is investigating the crash.

It was not known Wednesday if McCoy was responding to a call when the wreck occurred, or if his blue lights and siren had been activated.

Chief Deputy Ted Stanfield said state troopers instructed the Sheriff's Office to refer all questions about the crash to the Highway Patrol. Gaulden said he didn't have any specifics about what McCoy was doing at the time of the crash.
