Where can I find a good criminal lawyer in pa?

My son was charged with a rape he did not commit I know this for sure because he was not there when it happened he was with me and his father and several others. any way the girl that got raped went back into the bar and finished out the night drinking,she than went home took a shower used some type of yeast cream that had to be inserted and than went to sleep for several hours before going to the hospital. what is that called?
