A young Washington man with military experience and survivalist skills is suspected in the shooting death of a 34-year-old Mt. Rainier park ranger and mom of two. Benjamin Colton Barnes, 24, is also suspected in the shooting of four others wounded earlier at a Skyway house party, reports ABC News. Police believe he may have fled to the park after the party confrontation, was stopped by ranger Margaret Anderson, and shot her. He then vanished into the woods, armed with an assault rifle, according to cops. His car was found filled with body armor, survival gear, and weapons. Some 150 officers, including members of the FBI, state patrol, and local police, are hunting for Barnes in the park, where some 125 people are currently staying in lodges and cabins.
