The family of an Oklahoma Highway Patrol trooper killed in an accident Sunday says he died while trying to turn around on the Will Rogers Turnpike.
Trooper William McClendon's family says he was headed for an emergency call when he was notified the call was canceled. His sister-in-law says McClendon was trying to turn around through a concrete barrier opening when his vehicle collided with the semi. McClendon died at the scene.
The 25-year-old truck driver was thrown from his vehicle. He died at a Tulsa hospital.
The Oklahoma Highway Patrol is not releasing any other details during the investigation.
Troopers hope witnesses can help answer some of the questions they have about the accident. If you saw the crash or stopped to help, call the Oklahoma Highway Patrol at 918-627-0440 or toll-free 866-OHP-TIPS.
