You have not provided enough informatino to tell for certain what occurred. However, odds are that he waived the preliminary hearing. This is not in any way a plea of guilty - it only means that the case will be bound over to court for further proceedings. The first stage in a felony charge is a preliminary hearing in front of a District Justice, sort of a mini-trial. It is not unusual for defendants to waive this step, which changes nothing except the opportunity to perhaps obtain dismissal at the District Justice level. I used to be a District Justice in Pennsylvania, and did at times determine that the prosecution did not meet its burden for a bind-over, so never understood why a defendant would waive this step, but many do.
