The delicate search for a survivalist charged with killing a trooper more than two weeks ago shifted slightly over the weekend in the dense woods that authorities fear may be booby-trapped, state police said Sunday.
Trooper Adam Reed said the search area in the Pocono Mountains largely remains the same as the past two days but has moved slightly to the southeast.
Police are constantly following up on information they receive, Reed said. He declined to go into specifics about why the shift occurred or what new information police may have.
The search for 31-year-old Eric Frein entered its 16th day Sunday. Authorities believe they have Frein contained within a 5-square-mile perimeter around his parents' home in Canadensis.
Frein is described by authorities as a survivalist, marksman and war re-enactment enthusiast who planned the attack for years, extensively researching how to avoid police manhunts and experimenting with explosives. Frein has held anti-law enforcement views for many years, police said.
Investigators believe he is armed with at least one high-powered rifle and might have booby-trapped the woods where authorities are looking for him.
Frein is charged with opening fire at the Blooming Grove barracks during a shift change on the night of Sept. 12, killing Cpl. Bryon Dickson and seriously injuring Trooper Alex Douglass. He has managed to elude hundreds of law enforcement officials looking for him in the difficult terrain.
Frein has been placed on the FBI's Most Wanted list.
