Stalking? That poor child doesn't know the meaning of the word stalking :-(
Your husband sounds like he has a good attorney. Have a therapist check out those voice mail tapes. A neutral party could maybe get somewhere with her. I don't know, my youngest 2 are a couple of tough nuts to crack. I've given up on therapy for them. Haha, by the time we get out of here, I'm going to need it.
