TACOMA, Wash. (AP) — A Washington State Patrol trooper sustained minor injuries when he was struck by a vehicle while investigating a collision Sunday in Pierce County. The patrol says Trooper Pedro Martos was standing at the scene of the earlier collision on State Route 512 at about 3:15 a.m. when a pickup truck struck Martos’ vehicle, which had its emergency lights flashing. The trooper’s vehicle was shoved into a car involved in the original accident. The patrol says the driver of that vehicle and the driver of the pickup were not injured. Martos was treated for minor leg and back injuries and released from a hospital.
