CANADENSIS, Pa. - State police are lifting a shelter in place order for the area of northeastern Pennsylvania where a manhunt for the suspect in a trooper ambush is underway.

Homeland Security spokeswoman Maria Finn said in an emailed statement late Saturday that residents should use extreme caution as they move back into their homes in Barrett and Price Townships . She says police strongly recommend that residents stay inside and not enter the dense woods were officers are searching for Eric Frein.

The self-taught survivalist is accused in last week's deadly ambush at a state police barracks.

Officers are trying to flush 31-year-old Frein out of the boggy woodlands near where he lived with his parents.

Residents of the area are nervous about the police search activity near their homes.

"It makes us feel really unsafe," Rachel Rubino of Barrett Township told CBS affiliate WSEE. "Knowing that he's so close to us-- I keep looking out of my back window."

Police weren't offering any more information.

Frein is now the second most wanted man in America. There is a $175,000 reward for his capture, police say.
