Jerry Sandusky's decision Tuesday to waive his preliminary hearing shifts the focus in the child sex-abuse scandal to two Penn State administrators accused of failing to properly report suspected abuse and lying to the grand jury investigating Sandusky.

Tim Curley and Gary Schultz face their own pretrial hearing on Friday in Harrisburg, and although the charges are much different, with far less severe potential penalties, their cases could hinge on a man also expected to be a prime witness against Sandusky: assistant football coach Mike McQueary.

McQueary testified that he happened upon "rhythmic, slapping sounds" in the football team locker room showers in March 2002, and looked in to see a naked boy being sodomized by the former defensive coordinator, according to a grand jury presentment.

McQueary, then a 28-year-old graduate assistant, reported what he saw to then-football coach Joe Paterno, the grand jury said. Paterno called Curley, the university's athletic director, the next day, and a week and a half later McQueary met with Curley and Schultz — who oversaw university police in his position as a vice president.
