The Oregonian says troopers identified the man who died Thursday as 38-year-old Amos McLean of Eddyville.
Police got a call Sunday night about a naked man waving branches and shouting while standing on Oregon 20. They soon learned the man had been hit by a vehicle and critically injured.
Troopers say the man had been sitting in the westbound lane when a pickup with a travel trailer approached. They say the man threw his body against the side of the truck and punched at it before being struck by the trailer.
