Pennsylvania cop-killer Eric Frein's sister says he was her protector. Tiffany Frein testified that her father physically abused her and her brother made her feel like someone actually loved her. Frein was convicted of murdering Corporal Bryon Dickson in a 2014 ambush outside the Blooming Grove police barracks. The defense rested yesterday with no testimony from the Barrett Township man. Prosecutors are asking for the death penalty. The case is expected to go to the jury today.
