I feel so bad for your daughter and the other players. I deal with these types of cases too often. I can tell you from my professional experience that most victims feel better when word spreads, even if they aren't personally identified. Getting it to the media can be cathartic, and spread the word more broadly.
Please find a way to reach out to law enforcement, and spread as many documented details as you can (redacted texts, etc), to make this widely know in the local media.
Assuming what you have described is accurate, there must be many, many, many more victims.
