how can she get a ppo order or a no harrasment order?

basically, my neighbors 10 year old daughter was raped by her boyfriends 18 year old son. He was arrested, charged, and released until the trial date. However, the boys mother is consistently harrassing the mother of the little girl and the girl via phone. She has called and left messages like "you and your whore of a daughter will pay" "your daughter is a ****" "she didn't say no, so that means it wasnt rape" and on and on. I told her that there has to be something she can do or some protective order she can get to keep this woman from harrassing her. She said she went to the magistrate and was told by him that since her boyfriend has custody of their younger son, there is nothing that can prevent the mother from calling. Something like because they still share a child in common. I think its crap. Her boyfriend wants nothing to do with his 18 year old son and has been very suppotive of his girlfriend. Its the ex-wife who won't stop calling and harrassing.

Please! what can my friend do to get some type of order for protecting herself and her daughter.

Also, the exwife is posting information on facebook about the case and consistently calls the ten year all types of names via facebook. because of the rape and harrasment the child is undergoing counseling.

I'm just trying to help my friend. Please, only appropriate comments or suggestions.
