We just had a similar incident happen about 3 miles up the road.
Intruder broke in an couple's home in the early morning hours, the husband fired a warning shot and he didn't back off, so he killed him.
Ex is supposed to teach me how to shoot a pistol this spring (I've been left with 2 since mom passed away). He wants me to get a permit to carry since I'm always roaming, not sure about that yet, but I do want to get myself used to them.
