Two law enforcement officials speaking to the Associated Press said that Frein was captured Thursday by U.S. Marshals in an abandoned airplane hangar.
A reporter at WBRE tweeted what is reportedly the first photo of Frein in custody:
The capture ends a 48-day search for the man accused of killing a Pennsylvania state trooper, Bryon Dickson, and wounding another, Alex Douglass, on Sept. 12 in an ambush outside of Blooming Grove state police barracks.
Frein, 31, is a survivalist who eluded capture for weeks, despite several reports of sightings. However, authorities found several items believed to belong to Frein in the mountains, including military-style food packs, pipe bombs, ammunition and clothing.
Police also found a handwritten journal, which included what police described as a “cold-blooded” account of the Sept. 12 ambush.
The lengthy hunt unnerved nearby communities. Several schools closed in northeastern Pennsylvania last week as police investigated a possible sighting of the suspect.
