Highly unusual for a woman to use firearms as a means to do this. Mothers who do this sort of thing more typically take a more hands-on approach, using pills, poison, drowning, suffocation, etc. to murder their children. It’s typically men who use firearms in crimes of passion or insanity.
Either way, absolutely horrible outcome. Mental health really is something we need to get better about addressing in this country. The guns were never an issue here; the woman willing to use a gun or whatever other tool was available to murder her children: THAT was the issue.
In re mental health the article said she had no history of issues and cps had never been called out.
Also while I am all for mental health there is no evidence that our current style of encouraging nutty behavior and medicating is healing anybody.
