Colin Sullivan I attempted to subdue Trooper Barrigan at which time he drew down on me, and I was able to squeeze off one shot...and strike him in the head. At that time I immediately checked the vitals...on both Troopers Brown and Costigan and discovered that they had expired. I just wanna go on record. I'm recommending William Costigan for the Medal of Merit. Billy Costigan There is a rat in your unit, that is a fact. Billy Costigan They knew you had cameras in the building, they knew everything, alright? There is a leak from the inside. It's real, man. Smoke them out!
