SCRANTON — A state police trooper seriously wounded in a 2014 ambush a near a rural barracks in eastern Pennsylvania has put the accused shooter and his parents on notice that he plans to sue them.

Court documents were recently filed on behalf of Trooper Alex Douglass against Eric Frein and his parents, Eugene and Deborah Frein.

Scranton attorney Vincent Cimini filed a writ of summons on behalf of Douglass in Monroe County Court last month, notifying the Freins a lawsuit will be filed.

Cimini’s clerk told the newspaper he can’t comment.

Eric Frein is charged with fatally shooting Cpl. Bryon Dickson II and wounding Douglass outside the Blooming Grove barracks.

He led police on a tense 48-day manhunt before U.S. marshals caught him. He’s pleaded not guilty.
