Accident investigators are seeking witnesses to last week's serious injury collision in Kennewick involving two vehicles and a FedEx truck.
Karen Arbogast, 51, of Umatilla, was critically hurt after the truck apparently ran a red light on Highway 395 on Hildebrand Road and crashed into her van.
The truck, which was going north on the highway, first hit a Toyota Camry before colliding with Arbogast, who was crossing Highway 395, Washington State Patrol troopers said.
The crash was at 4:15 p.m. Oct. 19.
Never miss a local story.
Detectives with the state patrol major accident investigation team are looking for witnesses to events leading up to the collision and those who saw the crash, said Lt. Roger Wilbur.
