Pennsylvania State Police have struck out again after following up on a possible sighting of the suspect in last month's deadly ambush of police barracks in the Pocono Mountains.
The (Scranton) Times-Tribune reports hundreds of troopers searched a northeastern Pennsylvania tree nursery for hours Sunday, but didn't find Eric Frein.
The 31-year-old has eluded police for weeks, despite the intense manhunt in 5 square-miles of dense woods.
Cpl. Bryon Dickson was killed and Trooper Alex Douglass was seriously wounded in the Sept. 12 ambush.
Since the search began, police have found two pipe bombs at a campsite used by Frein and have found 90 rounds from a rifle of the type used in the ambush. They've also found tuna fish, ramen noodles and other food and clothing.
