CANADENSIS, Pa. (AP) — Roadblocks have been removed outside the northeastern Pennsylvania community where police searched for the suspect in last week's deadly police barracks ambush. But authorities urged residents to remain vigilant as the manhunt reaches its ninth day.

State police said Sunday they've still had no contact with 31-year-old Eric Frein (freen) despite the intensive search of the neighborhood where he lived with his parents in Pennsylvania's Pocono Mountains.

Police lifted a shelter-in-place order Saturday night and eased travel restrictions in the area. But residents were urged to take "extreme caution" as the search continues for a man described as a survivalist with a grudge against police.

Authorities say Frein used a high-powered rifle to open fire from the woods near a state police barracks on Sept. 12, killing one trooper and wounding a second.
