I wonder if she was worried about getting blood on her floor.
Lot less messy if he’s outside the house.
I would’ve shot him while he was still under the bed.
Her statement about if she "...sees a boy in my house I will put a hole in his ass...” is problematic for her defense as that implies forethought, and even worse, shooting him outside the house. If his daughter is saying that she said that, it might be judged hearsay in some way or contrived by the daughter and thus inadmissible, but..I am no lawyer.
We may or may not agree with her putting a bullet in that full grown man statutorily raping her daughter, but she has made the defense of her very difficult by shooting the man outside the house.
