Much better written story.
There is not enough information to determine what happened here. Doesn't sound like your typical “home invasion”. I think these people knew each other. Was the girl a villain or a pawn? Wait for more details. Opinions may change.
The grieving mother was so depressed that she took the time to get all “dolled up” (term used loosely) before she went on camera.
That one is better. But I’m not sure the details of who-knew-who-when make much difference in the moral outcome. Even if this turns out to be a reprisal for some earlier slight, what of it? Home invasion is a bad strategy for solving disputes. Lastly, a pawn pointing a gun at me is a villain.
