On this edition of Hero of the Day, Cam Edwards shares a story from Indianapolis, Indiana where a homeowner had to defend himself against a man with a knife. The homeowner answered a knock at the door only to find the suspect with a large knife demanding to know where the homeowner's sister was. When the homeowner did not comply, the suspect raised the weapon over his head and tried to enter the house. That is when the homeowner shot him with a legally owned gun, causing the would-be intruder to flee. Originally aired 10/7/2010.
