The indictment also cited a 1998 incident in which an 11-year-old boy's mother called university police to complain after learning that her son had showered with Sandusky. A state Department of Public Welfare investigator told the grand jury that Sandusky said he showered naked with the youth and hugged him, "admitted that it was wrong," and promised not to shower with any child again.
Kelly would not say whether Paterno or the university president knew of that investigation.
"All I can say is that investigation was handled by Penn State University's police department," Kelly said. Penn State police said they were not releasing any information about the 1998 case.
Sandusky retired in 1999 after learning that he would not be Paterno's successor as head coach.
Kelly and Noonan encouraged anyone who would accuse Sandusky of sexual assault to step forward and talk to police, with Kelly specifically asking that the child reportedly assaulted by Sandusky on March 1, 2002, call detectives.
Paterno has long had an image as a leader who does things by the book and runs a program that has seen far fewer off-field troubles than other major college football teams. Doubts about his judgment in handling the Sandusky matter quickly began to emerge.
Facebook users, including those on a newly created group called "Joe Paterno should resign," expressed outrage and disappointment in Paterno. Many said Paterno should have gone to police after the 2002 incident.
At Rinaldo's Barber Shop in State College, hair cutter Lori Schope said she believes Paterno shares responsibility.
"He passed the buck," she said. "Anybody that says they knew about it and didn't do anything about it is complicit."
Advocates for priest-abuse victims saw parallels in how the university and the Roman Catholic church handled similar problems.
"Here we are again," said John Salveson, former president of the Pennsylvania chapter of the Survivors Network of those Abused by Priests. "When an institution discovers abuse of a kid ... their first reaction was to protect the reputation of the institution and the perpetrator."
"They didn't even try to find out the identity of the kid that was being raped in the shower," he said. "Their solution to this was to not let Sandusky into the shower anymore. It's just stunning to me that no one called the police."
Sandusky was described by Keith "Kip" Richeal, co-author of his autobiography "Touched: The Jerry Sandusky Story," as a loving father of six adopted children
"I hope to God it's not true because I admire the man very much," Richeal said. "All I saw was Jerry was kind to kids of all ages, including the students he dealt with."
Sandusky has maintained his innocence, his lawyer said Saturday.
At Sandusky's two-story brick house at end of a cul-de-sac about five minutes from campus, a State College police car was parked in the driveway for a time Monday. An officer said police had been asked to keep people off the property, which included a neatly trimmed lawn with a pumpkin at the front.
Schultz, 62, and Curley, 57, are innocent and will seek to have the charges dismissed, their lawyers said. Curley's lawyer, Caroline Roberto, called the case weak, while Schultz's lawyer, Tom Farrell, said the men did what they were supposed to do by informing their superiors of the accusations.
"You folks may have seen Mr. Paterno's statement," Farrell told reporters. "Mr. Paterno's statement matches their statement. They were given a general allegation of inappropriate conduct. That's what Mr. Paterno told them, that's what Mr. Paterno told you folks yesterday, that's what he testified to in the grand jury, and that's what these gentlemen testified to in the grand jury."
Sandusky continued to use the school's facilities after retirement for his work with The Second Mile, a foundation he established in 1977 to help at-risk kids. The charges against him cover the period from 1994 to 2009.
