I agree with Shewolf. Physical evidence is so important! This....thing (he isn't a man) needs to be put behind bars. For your daughters sake and for the sake of any other little girls he may have come in contact with in the past or ones he may in the future. Chances are, your baby isn't the first. Sting him up, make him pay. He doesn't deserve any better.
Ugh! I just read the other post and was pissed off at the guy, only to read this?? I can't even call him any names because there isn't one in existance that can sum up what a vile creep he is!
I'm sorry, I can't offer any advice. I'm just disgusted and angry that someone you trusted could do this to a child. -_- And to you, and to the other children. He's just destroyed everything!
