(Milford) -- Lawyers for a survivalist charged with fatally ambushing a Pennsylvania state police trooper outside a rural barracks want his trial to be moved out of the area, citing extensive publicity about the case.

Court papers filed Tuesday say that Eric Frein can't get a fair trial in Pike County, in the Poconos, due to heavy news coverage about the 2014 ambush. His attorneys also say that Pike County District Attorney Ray Tonkin distributed campaign flyers last year that referenced the case and surrounded Frein "with an aura of guilt."

Frein is charged with fatally shooting Cpl. Bryon K. Dickson II and wounding another trooper. He led police on a tense 48-day manhunt before U.S. marshals caught him about 30 miles from the shooting scene. He has pleaded not guilty. Authorities are seeking the death penalty.
