Corpus Christi teen kills burglar in home, police say

CORPUS CHRISTI — A 14-year-old boy shot and killed a man who broke into his family's home today and threatened to kill him and his mother, Police Chief Bryan Smith said.

Smith said the man, whose name was not immediately known, confronted a woman as she was carrying groceries into her home shortly before 1 p.m.

The man forced her inside and tied up her and her son. Smith said the woman was able to loosen the binding and free her son, who got his father's revolver from a security box beneath a bed.

As the man tried to break into the room where the two were and threatened to kill them both, the teen fired a shot through the door and hit the intruder in the head, Smith said.

Yet another example of how home defense shootings involve barrier penetration. Still think that .22LR, 20ga birdshot, or 40gr ballistic tip .223 varmint load is a good choice?
