Former Penn State President Graham Spanier on Thursday became the latest high-ranking school official to face charges in the child sex-abuse scandal involving former assistant football coach Jerry Sandusky.

Spanier faces charges of perjury, endangering the welfare of children, conspiracy, obstruction of justice and failure to report suspected child abuse, Pa. Attorney General Linda Kelly announced in a news conference Thursday.

Additional charges were also filed against two other school officials already charged in the case.

Gary Schultz, former PSU senior vice president faces additional charges of endangering the welfare of children, conspiracy, and obstruction of justice.

Tim Curley, former PSU director of athletics, faces additional charges of endangering the welfare of children, conspiracy, and obstruction of justice.

“This is not a mistake, an oversight or a misjudgment.  This was a conspiracy of silence by top officials at Penn State, working to actively conceal the truth, with total disregard to the suffering of children,” Kelly said.

Schultz and Curley each already face charges of perjury and failure to report suspected child abuse.
