Two Stillwater residents were killed early Sunday in a head-on collision near Highway 177, according to the Oklahoma Highway Patrol.
Troopers say the crash happened shortly after midnight when a 17-year-old boy was speeding on a motorcycle without lights. Investigators said the teen struck a curb, veered into the opposite lane, and collided head-on with another car.
The driver of the car, a 78-year-old woman, was pronounced dead at the scene. Authorities say the teen also died in the crash.
Authorities have not released the names of those involved.
The collision remains under investigation.
