Curley and Schultz have been charged with perjury and failure to report under Pennsylvania’s child protective services law in connection with the investigation into allegations involving former football defensive coordinator Jerry Sandusky, the state attorney general’s office.

PHILADELPHIA — A court hearing in the Penn State child sex-abuse case could become a legal version of whisper-down-the-lane as two university officials fight perjury charges.

Former Vice President Gary Schultz and athletic director Tim Curley are charged with lying to a grand jury and failing to report sex-abuse allegations to police.

Longtime assistant football coach Jerry Sandusky waived his preliminary hearing Tuesday on charges he molested 10 boys. But lawyers for Curley and Schultz insist they will challenge the evidence at Friday's hearing in Harrisburg.

Then-graduate assistant Mike McQueary is at the heart of the administrators' case, and he may testify for the first time in public.

McQueary told the grand jury he saw Sandusky raping a boy. But Curley and Schultz say they remember McQueary reporting only inappropriate conduct.
