Is that a typo? Since she was one??? Threats or not, I can't understand why the parents didn't go the police.
And three murders (+ 1 who lived) on top of that?
This beast needs to be put down. I'm normally against the death penalty, but I'm not even talking about a death penalty. He just needs to be put down like the wild rabid animal that he is.
The parents were probably illegals too.
Who knows what kind of perverts the parents might be.
