TILLAMOOK — Investigators are seeking witnesses to a hit-and-run crash that injured seven people outside of Tillamook.

State police say a 1995 Ford Windstar van rear-ended a car driven by Steven Kershaw of Tillamook on Oregon 6 late Saturday.

The impact pushed Kershaw’s car into oncoming traffic, where it collided with a vehicle driven by Joshua Dreweck of Forest Grove.

Police say the green van left the scene and was later found abandoned in Tillamook, about a mile from the crash scene.

Kershaw and his two passengers were taken to hospitals, as were Dreweck and his three passengers. The injuries ranged from minor to critical.

Police are looking for people who witnessed the crash or who may have seen the occupants of the van leaving it in Tillamook.
