Mount Rainier National Park spokesman Kevin Bacher speaks to the media regarding the killing of a park ranger, near the park entrance January 1, 2012. The ranger, 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
