SHOOTING-RANGER

Benjamin Colton Barnes, 24-years-old, who is a person of interest in the killing of Mount Rainier National Park ranger Margaret Anderson on January 1, 2012, is seen in this undated handout photograph supplied by the Pierce County Sheriff's Department. 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. REUTERS/Handout (UNITED STATES - Tags: CRIME LAW) FOR EDITORIAL USE ONLY.
