Sixten-year-old Caleb Gordley was grounded for not cleaning his room. But, you know, he was 16, so he snuck out of his house to attend a party.

When he left the party about 2 a.m., Caleb needed to sneak home. His friends dropped him off and helped hoist him through a back window. But Caleb had been drinking and had gone to the wrong house. The brick homes on his street are similar, and Caleb was two doors down from his own.

The homeowner heard his burglar alarm sound, grabbed his gun and went to investigate. When the two met on the stairs inside the house, the man said he told the teen to leave and fired a warning shot, according to a law enforcement official with knowledge of the investigation.

Caleb didn’t stop, and the home-owner fired again, striking and killing the teen, the official said.

If only Gordley had cleaned his room like he'd been told, this tragedy never would have happened. But we're all safer for the fact that his neighbor owns a gun.
