STATE COLLEGE, Pa. (AP) — Three former administrators at Penn State are waiving their right to a formal arraignment on criminal charges in an alleged cover-up of reports about Jerry Sandusky’s behavior with boys.

Dauphin County court officials said Monday that Graham Spanier, Tim Curley and Gary Schultz signed the waiver paperwork last week, after a district judge ruled following a preliminary hearing that there was enough evidence to advance the case to county court.

The documents say all three men are pleading not guilty to the charges against them. Waiving formal arraignment is routine.

Spanier is the school’s former president, Curley is retired from the position of athletic director and Schultz is a retired vice president.

Sandusky is serving a decades-long state prison sentence for sexual abuse of 10 boys and is pursuing appeals.
