In a former place of employment, where beating someone with a bat, 2x4, or rocks, and stabbings were much more common than shootings we had something similar happen.
A guy came in on Mother's Day with a stab wound to the left upper arm and the left side of his neck, the neck one was pretty impressive, but we kept him alive, shipped him off and he lived to go back home. He must have forgotten the flowers for the mother of his children!
Turns out, this had happened before, just not bad enough to need to seek care, plus other forms of violence directed toward him.
On Father's Day the same year (appx 1 month after the neck stabbing) our EMS got a call for an unresponsive male, turned out to be our victim from the Mother's Day stabbing. He had a tiny, bloodless, stab wound just to the left of center chest, between the 4th and 5th ribs. He was dead and was not coming back. Turns out she used one of those cheap, tiny (but large enough), 99 cent paring knifes you can get everywhere. Very thin blade, but good enough to pop his left ventricle.
She was also upset he was dead, she had abused him, including stabbing a few times and he had never died on her!
She went to jail and committed suicide while awaiting trial. I have no idea what happened to the children, but with the culture on the Rez they are probably with a grandparent or other family member.
