Description of William North (Guard):

Using Frank as bait, Harley and the Joker decided to send him into the Intensive Treatment Lobby to face William North alone. North had no reason to suspect Boles, since he was oblivious to the fact that Frank had changed sides. Boles thus rushed into the lobby, urging North and his men to go cover the front entrance of the Intensive Treatment Lobby. As several security guards hurried to comply, one of North's colleagues asked how many inmates were present, before it dawned on them that Frank could not have possibly known this information. In response, Boles raised an assault rifle and began shooting. He shot the guard nearest to him, then fired on the two guards scrambling for the exit.
