What can be done to exonerate my son in a juvenile case from three years ago?

My son was found delinquent in an attempted , kidnapping case three years ago. The public defender didn't realize the kit was in his file until the prosecutor mentioned it to him at trial. No DNA evidence. The accuser tesitified she feared for her life because he had a pager. She claimed he drug her by her wrist for over 500 feet, at 4 p.m. in an area where there is always an abundance of people around but shesaw no one. The Public defender didn't submit the alibi in time and never utilized the witness list or the witnesses in the court house. I went to the Public defenders office to request an appeal. I was told they would file it but never did. I complained to the Ohio Supreme Court but it concluded the PD did a good job because he got the charge reduced to attempted . I have requested transcripts in Nov. 2006 but have yet to receive an answer. I was not notified of his conviction or sentencing at which the judge told my son "I'm surprised your reporter mother isn't here
