MILFORD, Pa. (AP) — A Pennsylvania prosecutor is formally notifying the court he’s seeking the death penalty for a man accused of killing one state trooper and wounding another in a barracks ambush.

Pike County District Attorney Ray Tonkin filed a document Tuesday listing aggravating circumstances that could send Eric Frein to the state’s death row.
