The new charges came almost exactly a year after details of the case against Sandusky sent a maelstrom through State College, toppling longtime head coach Joe Paterno and eventually leading to severe NCAA sanctions against the football team.
Sandusky, 68, vigorously contested the charges but was convicted in June of 45 counts of abuse of boys, including violent sexual attacks inside campus facilities. He was sentenced last month to 30 to 60 years in prison.
A grand jury report alleged Spanier testified falsely that he did not know of a 1998 complaint against Sandusky, made by a mother and investigated by university police.
It also claimed Spanier lied about a 2001 instance of abuse witnessed by a graduate assistant, when he testified that Curley and Schultz described it only as horseplay. Email traffic among the men, jurors wrote, "make clear they are discussing an event that involves the abuse of a child."
The grand jury report described how he addressed the growing scandal last year with the board of trustees, and how he put out statements supportive of Curley and Schultz after their arrest. The report said investigators were immediately able to get important records from the university after Spanier was replaced as president.
Spanier's lawyers put out a statement law week that accused Gov. Tom Corbett, who was attorney general when the investigation began, of orchestrating the charges to divert attention from questions about why it took three years to bring charges against Sandusky. They said there was no factual basis for the Spanier charges and said the grand jury report was "a politically motivated frame-up of an innocent man."
