The suspected gunman wanted in the murder of a Mount Rainier park ranger has been found dead, reports King 5 News. Benjamin Colton Barnes, 24, was found face down in chest-deep snow, and while there's no official cause of death, the AP notes that it appears likely that he froze to death overnight. Park officials had scrambled to evacuate the park after Ranger Margaret Anderson was shot to death yesterday after attempting to stop Barnes at a checkpoint in the park. (More Mt. Rainier stories.)
