Authorities on the trail of suspected trooper-killer Eric Frein have found diapers, cigarettes, and now two pieces of evidence with more sinister overtones: two fully functional pipe bombs, reports the Scranton Times-Tribune. Pennsylvania police, however, say Frein never got a chance to deploy the bombs because they were "hastily discarded" at one of his campsites, reports AP. "You are clearly stressed," said the state police official in charge of the search, directing his comments toward Frein himself. He urged the 31-year-old survivalist to turn himself in. "You are making significant mistakes."
Authorities say they are sure they're closing in on Frein, who is accused of killing one state trooper and injuring another one in an ambush shooting on Sept. 12. At least one credible sighting has been reported in the last 24 hours in the Pocono Mountains, in the general area of where Frein's parents live, say police. One recent search took place at an abandoned hotel in the area. (Read more Eric Frein stories.)
