Sections of Pennsylvania’s Pocono Mountains will be temporarily off-limits to hunters and trappers due to the continued manhunt for alleged cop-killer Eric Frein. The ban affects seven municipalities in Pike and Monroe counties that fall within state gaming lands formally called Wildlife Management Unit 3D, as well as any private land in those townships.

According to The Express-Times, the Pennsylvania Game Commission made the announcement just ahead of this weekend’s archery deer season opener. Today marks day 20 in the search for Frein, who is accused of staging an ambush outside the state police barracks in Blooming Grove, Pa. Frein killed one trooper and injured another. On Tuesday, police discovered pipe bombs allegedly left by Frein within the 5-mile area of the search. The Express-Times reports today that two state troopers were injured when they fell through the floor of a wooden treestand they were inspecting.

Law enforcement anticipates cooperation from the hunting community as restrictions have been put into effect for the safety of search personnel and local sportsmen.
