Good news either way:
If he is a juvenile he will continue doing the same and in a western small state is in for an awakening when he turns 21( or 18 ). They take adults doing that kind of thing far more seriously, and repeated slaps on the wrist end with becoming an adult.
When he turns an adult he will find:
1) judges realize that pedophiles have a 100 % recidivism rate when released. That's because the rest die in prison.
2) They have a name "shorteyes" in prisons for his type. Even cons dislike shorteyes. Really dislike them. Believe me on this - I sent 30 odd people back to prison to await the following month's Parole Board revocation hearings.
His odds of dying in bed in his 70's are not good. That's even if there is neither God nor Karma, which I wouldn't bet against even at 100 to 1 odds.
In the meantime get her a 20 ga. auto ( or pump ) youth model, and either get/give her lessons or show her as soon as she's big enough. And start her on 22 pistols/Jframe S&W's as appropriate.
( Addition on edit: get her a nice rifle. A paratrooper SKS or Saiga 10 round or M1 Carbine if auto in intermediate caliber, a 357 or 44 mag or 30-30 lever with light loads like 22 accelerators with power to increase with her expertise, or a lightweight youth bolt, say in 243, 250 Savage. )
I regret I don't have a spare castrating knife. Try calling a working cattle ranch and ask for the two of you to be invited to the nest rocky mountain oyster harvest... who knows, you may get a chance for some hands on practice...
( Edit again: She has her own khuk already, right? If not email UB about the occasional 9" like Yangdu had - or the CBKC size that comes in once in a blue moon. In the meantime, Yangdu can be on the lookout for the right 12" Sirupati. Get her her own tactical folder to clip in he pocket the first thing on home from school, and the last thing off on her way out the door to school. )
The next time you hit a town with a bookstore, especially if it's got an "X"tian bookstore, look ( ask if you have to ) for a book by Richard Foster, ( a Quaker who's written several books ) for a book called "Prayers From the Heart." Thin, small EXCELLENT book, and I'd give you the ISBN # but both of my copies are loned out. It has a multipart prayer in several consecutive parts for anger, leading up to FINALLY asking for God's forgiveness for the attacker - to be prayed by you for your own sake, and for your daughter to be prayed by her for hers. I think it cones in five or six parts, and it may take a week of more on each before movinge to the next step. If you and your daughter can accomplish that prayer it will release the hate, for both of your best interests.
Foster has written several absolutely excellent books on mechanics of untalked about disciplines in the Chistian church. One is "Celebration of Discipline" ( for some reason priests/ministers don't think the laity need to be taught about the various spiritual disciplines - nonsense! everyone involved in spiritual matters needs them ). Another is "Prayer", a much longer book than the "Prayers From the Heart". Foster (IIRC) does a comprehensive breakdown by chapter of each of the 7 inward forms of prayer ( for willingness to prepare for change ), upward forms of prayer ( for change, empowerment ), and outward, to bring newfound knowlege to action. All books are pretty nonsectarian. I should reread them myself, if I can get them back.
I keep them lent out so I don't have to feel guilty about doing the prayer for release for hatred myself. For my own good. I'll live a longer and happier life if I turn justice over to the "Occupant Upstairs", whomever s/he might be.
PS: If it looks like it's becoming increasingly possible, send me an email and I'll loan you my Primble castrating knife. To be returned later of course.
