GREENSBURG (KDKA/AP) -- Some local state troopers are now heading to northeastern Pennsylvania to help in the intensive manhunt for the suspect accused in a deadly ambush at a state police barracks.
Troopers from the state police barracks in Greensburg, Westmoreland County, have been called in to help with the search for 31-year-old Eric Frein of Canadensis, Pa.
They will be relieving law enforcement officials there who have been working round the clock.
"Each station is trying to send a handful of people to head up to Pike County and relieve the people that are there," said Trooper Steve Limani, of the Greensburg State Police Barracks.
Frein is charged with killing Cpl. Bryon Dickson and wounding Trooper Alex Douglass outside of the state police barracks in Blooming Grove on Sept. 12.
Law enforcement officials are now searching the rural area where Frein grew up and his parents still live.
"We know that Frein has prepared and planned extensively for months and maybe years. He planned his attack and his retreat," said Lt. Col. George Bivens, of state police.
The search for Frein is in some of the most dense, rugged terrain in the Commonwealth. For law enforcement, it's mentally and physically taxing work looking for a person who is looking to kill them.
"We're doing our best to try and keep our men and women fresh," said Trooper Limani.
As tough and as dangerous as it is, it's more than an assignment.
"There's not a shortage of people who want to go out there from our end of the state, from all over the state to go out and help find this person that shot and killed one of our brothers and injured another one," added Trooper Limani.
Meanwhile, Gov. Tom Corbett said Monday that he's confident Frein will be caught.
"My fervent wish is that we conclude this as quickly as possible. This is a very dangerous individual," he said.
Authorities have called Frein a self-taught survivalist with a vendetta against law enforcement. State police have followed up on hundreds of tips and reported sightings. None have panned out. But police officials insist they are hot on his trail.
Schools in the Poconos reopened Tuesday, but officials have added extra security.
Investigators have said they do not think Frein will attack any civilians, only law enforcement officials.
They believe Frein acted alone.
