First, some background: Sandusky retired as defensive coordinator in 1999 but was given "emeritus" status within the school, Attorney General Linda Kelly said.
According to the presentment, Sandusky had unfettered access to campus and an office at the Lasch Football Building, even though, as Schultz testified to the grand jury, he had been the subject of a 1998 university police investigation. The investigation included allegations of sexually inappropriate behavior involving Sandusky and young boys in the football building showers.
Sandusky's activities again drew attention in March 2002 when, Kelly said, a graduate assistant football coach "reportedly observed Sandusky sexually assaulting a naked boy who appeared to be about 10 years old."
The graduate assistant told his father, and the two informed Paterno the next day, the presentment stated. Paterno testified to the grand jury that he reported the allegation to Curley, who then handled -- or perhaps mishandled -- the matter in conjunction with Schultz.
