He needs to make a motion to have his public defender changed due to ineffective counsel. You should also consider championing his cause by speaking with this attorney's supervisor, explaining that while they all have large dockets, he is not zealously advocating for his client and this is ineffective counsel. You want a new lawyer assigned immediately with the goal of getting him out of jail and dealing with these charges while he is out. Further, he needs to bring this motion to court and see if that can get the ball rolling. After this is all done, he may wish to file a complaint against this public defender through the Pennsylvania state bar.
