Police Officer James Holmes said Saturday that the teen and his brothers and sisters were at home alone when a woman rang the doorbell Friday. The teen didn't open the door because he didn't recognize her.
Soon after, the teen heard a bang on the door, rushed his siblings upstairs and got a handgun from his parent's bedroom. When he got to the top of the stairs, he saw a man breaking through the front door and point a gun at him.
The boy shot the 37-year-old man, who is in critical condition but expected to survive and be booked into jail.
