The Washington State Patrol says an 18-year-old man was run over and killed when he fell from the bed of a moving pickup truck on the Lummi Reservation.

Trooper Mark Francis says Isaac O. Misanes, of Ferndale, was seated in the rear of a cab on and somehow managed to crawl through a sliding rear window into the truck bed.

Francis says the teen fell from the truck and a back tire on the driver's side ran over him. He died at the scene Wednesday.

Misanes was riding in the truck with three others. The Bellingham Herald reports  that 25-year-old driver is not suspected of driving under the influence of alcohol or drugs.
