Intruder enters home in middle of night; shotgun-toting homeowner tells him to get out. When intruder doesn't comply, homeowner shoots him dead.

It was a quick exit for an alleged home intruder in Webster Groves, Missouri, late last week — but he didn't depart the way he came in.

What happened?

Police in the St. Louis suburb were called at 2:51 a.m. Friday for a "burglary in progress" in the 1400 block of Grant Road, the St. Louis Post-Dispatch reported.

A man had entered a home through a back door but was soon confronted by the homeowner, police told the paper.

And the homeowner planned ahead for just such an occasion by exercising his Second Amendment rights. Police noted to the paper that the homeowner was armed with a shotgun.
