Sleeping Grandson Killed...

I would of never thought that something like this would be possible. I know that most people say that there's always a first but come on now, I'm curious as to what went down that triggered her to shoot the man and then set the house on fire. I have had many arguments with my mom and grandmother but I would never get in a heavy argument if I knew that sleeping would be a sign of weakness. Someone has to file some sort of appeal to get her to say what happened that day. Just when you thought you saw it all.
