Since she's a minor and they're helping corrupt her, perhaps they could be pressured into cutting off contact with her or face charges. She's not doing this all on her own. There must be someone in her cadre that's over 18 that could be pressured.
It's a very bad situation for you, and I feel for you and your family.
But realistically, unless you can find FL law that clarifies things better, I think Don's suggestion of locking up everything you can is probably the best you can do until she's 18. :-(
Best of luck.
Cheers,
Scott.
