Lisalee,
With the facts you report and the injuries logged he will be looking at a long sentence, however you went to him - did any other people witness or hear what happened?
It appears his mother is the only witness, what will she say - you came round shouting the odds - wheres my money etc etc.
The court case can be very involved but contact witness care and find out whos dealing with the case.
Contact the police officer in charge and make sure they keep you informed as to the progress regularly
BEST OF LUCK
