The vehicle belonging to the gunman who shot and killed Mount Rainier National Park ranger Margaret Anderson during a routine traffic stop, is seen in the park late January 1, 2012. Anderson, a 34-year-old mother of two young children, was killed after she stopped the gunman's vehicle at a roadblock shortly after another ranger tried to stop the same car about a mile away, park spokesman Kevin Bacher said in a statement. Authorities have closed the park on the west side of the snow-capped Cascade mountain range as police search for the gunman.
