Officer say, the homeowner heard a sound at his back door. When he went to look, he saw a man in dark clothing trying to break into his home using a knife.A "prowler," to me anyway, is someone creeping around your back yard. Someone actively trying to break in is at least a burglar, but more like a home invader.
One shot from a rifle sent this guy running like a rabbit. (He dropped his knife.) No blood, so police don't believe he was shot. Sounds like no clues.
Still, someone actively breaking into my home is a threat and will be dealt with accordingly. What would you do? Invite him in for tea?
