Two semis crashed head-on on Highway 69 in Muskogee on Saturday night.
Officers say the southbound semi failed to stop at a light and swerved into the northbound lanes, hitting a car, then pinched it between another semi.
A person in the car was pronounced dead at the scene.
The wreck is at Arline Avenue and has northbound traffic being rerouted from Peak Blvd (Highway 33). Southbound traffic is down to one lane.
