On this edition of Hero of the Day, Cam Edwards shares a story from Western Pennsylvania where Bill Miller, the owner of a Dormont auto repair shop, and a deliveryman were attacked by Lonzy Westbrook, 39. Westbrook entered the shop and forced the two victims to kneel at gunpoint while he robbed them. When he walked outside with the goods, Miller retrieved his firearm. Westbrook returned, pointed his weapon at Miller's chest, and that is when Miller shot him fatally. Miller is a firearms instructor and a Vietnam veteran. Originally aired 8/19/2011.
