Personally, I think a night in jail would do him good. Abuse is abuse -- and any child who is being abused NEEDS HELP. If this young person is being abused, then the police NEED to be called! If you really want to help her, make SURE she calls the police next time. He needs to be prosecuted!!! He cannot keep beating her, her brother and/or her mother! Someone is going to get badly hurt or KILLED. This isn't a movie -- this is real life you're looking at.
Forget the tuition for now -- there is always help available. If she gets killed she won't need it, will she!
So he's going to keep on abusing because he thinks no one is going to call the police, huh? Well next time MAKE her call the police, or YOU do it for her! He has GOT to go to jail and be punished for abuse! This man is dangerous!! And the mother has GOT to sign a complaint! Make the girl call the police PLEASE. And like I said -- forget the tuition. She can get help with that later.
God bless and please take care of YOU AND YOUR FRIEND. Hugs, Lee
