Authorities say their discovery of two pipe bombs during a massive manhunt in the Pennsylvania woods shows the fugitive is stressed out and making mistakes.

State police Lt. Col. George Bivens says the explosives were not deployed, but they were fully functional and capable of causing significant damage.

Bivens called on 31-year-old Eric Frein (freen) to surrender. Frein has been on the run since Sept. 12, accused of killing one state trooper and wounding another in the Pocono Mountains.

Authorities believe the self-taught survivalist is hiding in thick woods near his parents' home in Canadensis.

Tuesday's disclosure about the pipe bombs comes as deer hunters prepare for the opening of bow season. The rugged terrain is teeming with hundreds of heavily armed law enforcement officers.
