OKLAHOMA CITY (AP) - Authorities are searching for the driver involved in a hit-and-run crash that killed a 36-year-old Oklahoma woman.

The Oklahoma Highway Patrol said Thursday that a vehicle traveling west on U.S. Highway 70 in Cotton County struck and killed pedestrian Sylvia Bilyeu around 3:45 p.m. Troopers say the Randlett resident was standing in the middle of U.S. Highways 70 and 277 when she was hit.

The patrol says the unknown driver's vehicle struck Bilyeu, left the road and then drove away.

The victim was pronounced dead at the scene.
