A massive manhunt is continuing for an eighth day to find suspected cop killer Eric Frein.

The 31-year-old "survivalist" is wanted as the primary suspect in the murder of one Pennsylvania state trooper and the wounding of another in a targeted attack last Friday at a police barracks.

Frein is presumed to be hiding in the rugged terrain and heavily wooded areas near the police barracks and his parents home in rural Pennsylvania, where, last night, gunfire erupted.

Bryan Llenas joined Uma Pemmaraju on America's News Headquarters from Price Township, Pennsylvania, and reported that it has not been confirmed if those shots fired were exchanged directly with Frein or not.

Llenas said that authorities are methodically searching cabins, campsites and vacation homes, in addition to miles and miles of dense woods.

The fact that Frein is a local who knows the area well, not to mention a self-taught survivalist, only makes the ongoing manhunt more dangerous.

FoxNews.com reported:

Authorities closed roads in the wooded neighborhood where the suspect, Eric Frein, 31, lived with his parents.  They told residents to stay in their homes as the manhunt continued Saturday morning.

Police have been largely silent about the details of their search, including how big of an area they are combing, whether they have the suspected shooter surrounded or how much longer it will be before residents can move about freely.

Police have charged Frein with ambushing Cpl;. Bryon Dickson outside a state police barracks in northeastern Pennsylvania on Sept. 12. Frein, a self-described survivalist with a grudge against law enforcement and government, is also accused of wounding another trooper.

As state police appeared to undergo a shift change, an unmarked helicopter flew overhead early Saturday, its lights off.

Frein was placed on the FBI's 10 most wanted list, and hundreds of law enforcement officials have been searching for him in the dense woodlands surrounding his home in Canadensis. Schools in the area were closed again Friday.

Canadensis resident Richard Barry couldn't get home from work Friday night before the roadblocks went up. Barry said Saturday morning that he heard from family members who were at home and they told him police were going through their yard and the dog was barking.

Worried about his family, he said he preferred to wait it out at the police line in hopes of hearing something rather than staying overnight at the firehouse.

"I'm hoping that sooner or later he (Frein) just says 'I give up. You win,'" Barry said.

The mountain forest canopy provides cover for anyone who doesn't want to be found and a suspect has his pick of places to break into and steal food. Pike County, where the barracks are located, boasts more than 14,000 seasonal or recreational homes.
