HARRISON — The driver in a fatal crash Thursday night is the subject of a criminal investigation after the sport utility vehicle she was driving went off Route 35, killing a passenger.

The driver was a female juvenile, according to police. Her identity hasn’t been released.

Capt. Jeff Davis of the Cumberland County Sheriff’s Office said no charges had been filed against her as of Friday afternoon.

Thomas C. McLendon, 18, of 81 School House Road in Oxford, was killed in the accident. He was riding in the back seat and was pronounced dead at the scene.

Passenger Jacob R. Hill, 21, of 18 McWain Hill Road in Waterford was flown to Central Maine Medical Center in Lewiston with life-threatening injuries, Davis said. On Friday, he remained in serious condition, according to a hospital representative.

Passenger Timothy S. Coffin, 21, of 461 Black Guard Road in Waterford was taken to Bridgton Hospital with serious injuries. He was treated and released, according to hospital spokeswoman Pamela Smith.

The driver was also taken to Bridgton Hospital with serious injuries, Davis said, but it was unknown if she was still a patient Friday.

The four were riding in a 2003 Chevrolet Blazer headed north toward Waterford at 8:23 p.m. Thursday when the driver lost control on a curve near 142 Waterford Road. The SUV crossed into the southbound lane and left the road, hitting several trees, Davis said.

The accident remains under investigation, he said.
