The Oklahoma Highway Patrol needs your help in a hit and run accident that took place yesterday.

 The OHP says the crash happened sometime between 2:00 am. and 4:20 am. on US-377, 7 miles north of Tishomingo.

 46-year-old Carla Johnson was walking southbound along the highway when an unknown vehicle also traveling southbound struck and killed her, and then left the scene without stopping.

 Investigators did not find any vehicle debris at the scene, but a possible 32-inch tire imprint, possibly from a raised pickup truck with a ranch guard push bar on the front, was found.

 Anyone with information is asked to call OHP Troop F headquarters at 580-223-8800.
