One person died in a wreck in Awendaw about 10 p.m. Wednesday, Charleston County Sheriff’s Office spokesman Maj. Jim Brady said.

The single-vehicle crash happened on Doar Road near Highway 17.

The Charleston County Coroner’s Office identified the man killed as 20-year-old John Taylor Early of Mount Pleasant.

The white 1996 Honda Accord that Early was driving ran off the right side of the road and struck a tree, Brady said.

Two passengers, who weren’t wearing seat belts, were injured and transported from the scene to Medical University Hospital, Brady said.

Early, who was wearing a seat belt, suffered fatal injuries.

The cause of the accident is under investigation, but Brady said excessive speed was a factor and alcohol was found in the vehicle.
