From the information I have seen, the woman has not taken the abuser back for 15 years and has a lifetime protection order granted 15 years ago.
The Murderer did violate the order, but, apparently the woman never invited or permitted contact for 15 years.
Still investigating.
Was he already a violent offender when she first started dating him?
When you willingly bring people like this into your life, it sometimes takes more than a piece of paper to keep them away.
One of the cases I’m aware of, the woman had a protective order but was still meeting the man for sex. And, yes, he beat her severely. Don’t know what happened after that as I moved away. But I wouldn’t be surprised if she kept doing it.
