Two of the three you cite were the sidekicks of violent men. It is extremely unlikely that, had they never met those men, they would ever have killed.
I totally acknowledge that but they were and still are front page news thats my point. Even when they are not the "killer" the women are still front page news for many years after.
Why isn't this woman?
1. Pestered the victim for sex
Unusual yes but not unheard of.
2. Bought a circular saw and used it to dismember the victim into six parts
Very unusual. I agree. Female murders tend to be disposers not dismemberers. Too much mess. Too much clean up. Too much in general.
Historically women are in the moment murderers or throw away murderers as in dump babies in rivers or pretend it was natural. Women very rarely go in for dissection.
I distrust the media so much at the moment I have decided to keep my thoughts to myself on this one.
