Sandusky, who worked with at-risk children through his Second Mile organization, was charged with seven counts of involuntary deviate sexual intercourse; eight counts of corruption of minors, eight counts of endangering the welfare of a child, seven counts of indecent assault and other offenses."It is also a case about high-ranking university officials who allegedly failed to report the sexual assault of a young boy after the information was brought to their attention, and later made false statements to a grand jury," Kelly said.Prosecutors said all of the young men first encountered Sandusky through Second Mile.A grand jury report, which recommended charges, said the first to come to light was a boy who met Sandusky when he was 11 or 12. The boy received expensive gifts and trips to sports events from Sandusky, and physical contact began during his overnight stays at Sandusky's home, jurors said. Sandusky was banned from the child's school district in Clinton County in 2009, after his mother reported alleged sexual assault to his high school. That triggered the state investigation that culminated in charges Saturday.Kelly said that seven years before that incident, in 2002, a graduate assistant saw Sandusky sexually assault a naked boy, estimated to be about 10 years old, in the locker room of the Lasch Football Building on the Penn State campus. The grad student and his father reported the incident to Paterno, who immediately told Curley, prosecutors said.Curley and Schultz met with the graduate assistant about a week and a half later, Kelly said."Despite a powerful eyewitness statement about the sexual assault of a child, this incident was not reported to any law enforcement or child protective agency, as required by Pennsylvania law," Kelly said. "Additionally, there is no indication that anyone from the university ever attempted to learn the identity of the child ... or made any follow-up effort to obtain more information from the person who witnessed the attack."Sandusky, once considered a potential successor to Paterno, drew up the defenses for the Nittany Lions' national-title teams in 1982 and 1986.The jury said Curley lied when he testified repeatedly that he was never told Sandusky had engaged in sexual misconduct with a child, Kelly said, adding that portions of Schultz's testimony also were not deemed credible by the jury.Penn State president Graham Spanier called the allegations against Sandusky "troubling" but said Curley and Schultz had his unconditional support and he predicted they will be exonerated.
