Call around to Appellate Lawyers to see who will look at the case to see if you have grounds for appeal....contact the local Bar association for a list of attornies who deal in "post conviction" or appellate matters. The local chapter of the National Association of Criminal Defense Lawyers might also be able to provide some names... With what you've told us, it certainly sounds like the DA inflated the charges...even if what the girl said is true and someone gave her a "wedgie", at most that is simple assault not a sexual crime, so there is a chance that a good lawyer can get that conviction overturned or the charge reduced on appeal...Good luck.
