(AP) — The suspect in the deadly ambush at a state police barracks in a remote part of northeastern Pennsylvania remained at large for a ninth day Sunday as police appeared to have narrowed their search, largely shutting down the area where he lived with his parents but leaving neighbors with few answers about what's going on just outside their front doors. With a helicopter flying overhead, law enforcement officers wearing bulletproof vests and armed with rifles continued their hunt for Eric Frein, 31, now on the FBI's Most Wanted list. Police released few details about their search of the heavily wooded community in the Pocono Mountains, saying only that they were exercising extreme caution. Late Saturday night, authorities lifted a shelter in place order but urged residents who didn't make it home Friday before the barricades went up to use caution returning home and to stay out of the dense, boggy woodlands where the search was underway. Authorities say Frein used a high-powered rifle to open fire from the woods near a state police barracks on Sept.
