Pennsylvania state troopers are defending themselves against complaints they've unfairly denied residents access to their homes during the manhunt for a suspected killer.

In a statement Tuesday, the police force says it's been "diligent in respecting the rights of the public" while working to keep residents and law enforcement officers safe.

But some people in the village of Canadensis have ended up sleeping in their cars because police cordoned off entire neighborhoods looking for 31-year-old Eric Frein (freen).

Authorities say Frein ambushed the state police barracks in Blooming Grove on Sept 12. He is charged with fatally shooting Cpl. Bryon Dickson and wounding another trooper.

While police search, residents say they've been kept away from their homes for more than 24 hours, leaving elderly relatives unattended and pets unfed.
