MOUNT RAINIER NATIONAL PARK, Wash. (AP) — Authorities evacuated about 125 people overnight from the visitors center at Mount Rainier National Park,where police have been searching the snowy terrain for an armed gunman

suspected of killing a park ranger.

About 150 officers converged on the mountain park after ranger Margaret Anderson was shot to death Sunday morning, and searchers used an aircraft with heat-sensing capabilities to hunt from the skies.

Authorities believe the gunman was still in the woods, with weapons.

Pierce County Sheriff's spokesman Ed Troyer said that Benjamin Colton Barnes, a 24-year-old believed to have survivalist skills, was a "strong person of interest" in the slaying.

A parks spokesman said Barnes was an Iraq war veteran, and the mother of his child had alleged he suffered from post-traumatic stress following his deployments.

Barnes was involved in a custody dispute in Tacoma in July, during which the toddler's mother sought a temporary restraining order against him, according to court documents.

In an affidavit, the woman wrote that Barnes was suicidal and possibly suffered from PTSD after deploying to Iraq from 2007 to 2008. She said he gets easily irritated, angry and depressed and keeps an arsenal of weapons in his home.

Barnes was also a suspect in the early Sunday morning shooting of four people at a house party south of Seattle, police said.

Sgt. Cindi West, King County Sheriff's spokeswoman, said late Sunday that Barnes was connected to an early-morning shooting at a New Year's house party in Skyway, south of Seattle that left four people injured, two critically.

That shooting happened about 3 a.m. and stemmed from an argument over a gun.

At Mount Rainier around 10:20 a.m. Sunday, the gunman had sped past a checkpoint to make sure vehicles have tire chains, which are sometimes necessary in snowy conditions, Bacher said.

One ranger began following him while Anderson, a 34-year-old mother of two young children who was married to another Mount Rainier park ranger, eventually blocked the road to stop the driver.

Before fleeing, the gunman fired shots at both Anderson and the ranger that trailed him, but only Anderson was hit, Bacher said. Anderson would have been armed, as she was one of the rangers tasked with law enforcement, Bacher said. Troyer said she was shot before she had even exited the vehicle.

About 150 officers, including officials from the Washington State Patrol, U.S. Forest Service and FBI, were on the mountain Sunday.

Tactical responders wearing crampons and snowshoes pursued what appeared to be the gunman's tracks in the snow, Troyer said. Those tracks went into creeks and other waterways, making it more difficult for crews to follow.

"He's intentionally trying to get out of the snow," Troyer said.

Authorities recovered his vehicle, which had weapons and body armor inside, Troyer said.

A SWAT team was able to remove Anderson's body from the mountain late Sunday night, with a procession of law enforcement vehicles escorting her remains away.
