My heart hurts for you. What a beautiful girl, I am so sorry for your loss. I don't know what the answer is, to fix our broken legal system. I've been there with my 2 teenage daughters, where the police and school either can't or won't help. That doesn't seem like justice for you. Being a juvenile isn't an excuse. Yes their brains aren't fully formed, but you do know right and wrong by 12. That's been established by science too. I hope with time you can be at peace, sending you love 💔💓
