How sad for both women, both the killer and victim.
 
It is easy to say 'lock her up' but the extenuating circumstances are extreme and woeful. If I understand correctly "It was the 20th time the local Department of Human Services contacted Hanchett" when she was a child in Arizona, living in extreme abuse.  How can such extreme abuse of children be allowed, even in Arizona?  Why did the State take no action to remove her from such a rotten environment?  We are all to blame!

I believe we can assume Hanchett was an emotional basket case that needed help, long before the crime.  It is understandable that she was in an abusive relationship at 18 years old.  Again, I must reiterate that our 'system' of mental health services is grossly deficient and under funded.  That is not to say that professionals could have 'saved' this poor individual, but at least she may have never gotten into the biker gang and the situation where she felt she had no option but killing another women.
