State police searching for a man accused of killing a trooper said Tuesday they found two pipe bombs in the Pennsylvania woods during their manhunt that were capable of causing significant damage.
The bombs were not deployed, but they were fully functional and had both trip wires and fuses, Lt. Col. George Bivens said at a news conference.
The weapons were among several items that suspect Eric Frein “clearly hastily discarded” at a Pocono Mountains campsite, said Bivens, who then called on the fugitive to surrender.
“You are clearly stressed,” Bivens said. “You are making significant mistakes.”
Frein, 31, has been on the run since Sept. 12, charged with killing one state trooper and wounding a second outside their barracks in Blooming Grove.
Authorities believe the self-taught survivalist is hiding near his parents’ home in Canadensis. Bivens said there had been at least one credible sighting of Frein in the past 24 hours, from between 75 yards and 100 yards away.
Police said last week they were treating the search area as if it was booby-trapped, because of evidence Frein had been experimenting with explosives.
Bivens said he believes Frein abandoned the pipe bombs because he was “under pressure” from the massive law enforcement presence. Items found with the pipe bombs “conclusively lead us to know they belong to him,” Bivens said, though he declined to identify other objects.
The bombs had the capability of causing substantial damage, Bivens said.
The disclosure comes as deer hunters prepare for bow hunting season to open this weekend. Bivens declined to comment on whether the Pennsylvania Game Commission would impose hunting restrictions in the area, which is teeming with heavily armed law enforcement officers.
“That does cause us some concern,” Bivens said. “Nonetheless, we can’t suspend our search.”
A Game Commission spokesman could not be reached for comment Tuesday. Hunters have been asked to keep an eye out for cabins or other structures that look like they’ve been tampered with or used by Frein.
