On Thursday, Judge John Cleland directed state prosecutors to turn over materials that are not in dispute before a pretrial hearing on Wednesday in Bellefonte, and to say in writing by Monday if there are remaining discovery disputes.
Additionally, ex-FBI director Louis Freeh and his team have conducted more than 400 interviews in the internal investigation spurred by the charges against Sandusky, Penn State trustee Kenneth Frazier said Friday.
Frazier said the investigation includes current and former employees from numerous departments across the university, which employs more than 18,000 at its main campus in State College.
The school still hopes the investigation will be completed by the time the next academic year begins in late August. The board still intends to make the full findings and recommendations public, Frazier said.
But, he added the time of the report timing "will be dictated by how long it takes to complete a thorough investigation."
School officials said nearly all of the trustees have now been interviewed.
And in Harrisburg, two Penn State administrators charged with lying to the grand jury investigating Jerry Sandusky filed court documents Friday that argued prosecutors have not produced enough evidence to support the perjury charges against them.
Athletic director Tim Curley, now on leave, and retired vice president for business Gary Schultz outlined the reasons they believe charges should be thrown out. Curley's filing cited what he called "a shifting sand approach" by prosecutors and said the court record so far did not include the basic elements needed for a perjury case to proceed.
Schultz's reply called the case "unprovable, unfounded and untimely" and said prosecutors acted prematurely with an exaggerated grand jury presentment to tarnish them with the child sexual abuse allegations against Sandusky. The attorney general's office declined to comment.
