Trooper hit by truck during accident investigation

A Washington state trooper was hit by a pickup truck early Thursday while investigating another accident. The officer, who has not been identified, has been treated for minor injuries.

The State Patrol says 46-year-old Stephen Merrill of Burien has been arrested and booked into King County jail under investigation of driving under the influence of drugs.

The state trooper was standing about 15 feet off of the roadway at about 5 a.m. when he saw headlights moving toward him. A red pickup truck rotated off the road and struck him and the two vehicles that had already been in a collision. No other injuries have been reported.
