ATHENA, Ore. -

A prosecutor says a northeast Oregon police officer fatally shot an armed man who aimed a pickup truck at him. Law enforcement officers in the area had been looking for the man since he eluded them in a high-speed weekend chase.

Umatilla County District Attorney Dan Primus said Athena, Ore., police Sgt. Erik Palmer located the man and his truck early Monday morning. The prosecutor says Palmer tried to wait for back-up officers, but the truck driver drove straight at the officer, who shot out the truck's tires. Primus says when the man got out of the vehicle with a gun, Palmer shot and killed him.

The prosecutor identified the dead man as 55-year-old Tere David King of Athena.

The East Oregonian reports that Saturday's chase began when Milton-Freewater, Ore., officers tried to talk to King about unspecified misconduct.

  Palmer is on paid administrative leave while the shooting is investigated.
