An Ada man was killed in a one-vehicle accident west of Wanette Tuesday morning, the Oklahoma Highway Patrol reported.

That crash occurred about 9:27 a.m. on SH 39, about .6 miles west of Wanette in Pottawatomie County.

The patrol reported Scott Ray Grissom, 35, Ada, died at the scene.

He was driving a 2012 Chevrolet Silverado westbound on SH 39 when he failed to negotiate a curve to the right, the OHP said.

As a result, the vehicle departed the roadway to the left and struck a tree before overturning and spinning one complete time, troopers reported.

Grissom, who was pinned, was pronounced dead at the scene by the Lighthorse Police Department, the patrol reported. He was extricated by Asher firefighters and transported by Criswell Funeral Home to their facility in Ada.

Cause of the collision, as well as the driver's condition at the time of the crash, are both listed as pending further investigation.

It was raining at the time of the accident. Seat belts were in use, the OHP said.

Trooper Joe Porter of the Pottawatomie County detachment of Troop A investigated the accident, with assistance from Trooper Tyler Jack from the Pontotoc County detachment, along with Pottawatomie County Sheriff's Office, Lighthorse Police Department, Asher and Wanette Fire Departments and Wadley's EMS.
