The investigation into the alleged sexual abuse of children by retired
assistant football coach
began in 2009 with the first report of allegations to law enforcement. But allegations and eyewitness accounts, some known to university officials, date back as far as 1994.
Here's the timeline of events, compiled from the grand jury report, the Pennsylvania attorney general's office and a statement from The Second Mile, a charity founded by Sandusky to help troubled youth:
: According to the grand jury report, Sandusky engages in inappropriate conduct with three boys he met separately through The Second Mile. One boy was 7 or 8, another was 10 and the third was 12 or 13. According to the report, the now-grown men said Sandusky engaged in inappropriate conduct ranging from touching to outright sexual encounters.
: Penn State police and the state Department of Public Welfare investigate an incident in which the mother of an 11-year-old boy reported Sandusky had showered with her son and may have had inappropriate contact with him. In a June 1, 1998, interview with investigators, Sandusky admits showering naked with the boy, admitting it was wrong and promising not to do it again, the grand jury report says. The district attorney decides no charges will be filed and the university police chief closes the case, according to the grand jury.
: Sandusky retires from Penn State after coaching there for 32 years, but retains full access to the campus and football facilities.
Sandusky showers with a young boy and tries to touch his genitals during overnight stays at the coach's house, according to the now 24-year-old man's testimony in the grand jury report.
: Tim Calhoun, a janitor at the Lasch Football Building on the Penn State campus, tells his supervisor and another janitor he saw Sandusky performing oral sex on a young boy, according to the grand jury report. A second janitor reports he saw Sandusky and a boy leave a shower room and walk out of the building hand in hand. No one reports the incident to university officials or law enforcement, according to the grand jury.
March 2, 2002
: According to the grand jury report, a graduate assistant tells coach
he saw Sandusky in the locker room shower the night before, performing a sex act on a young boy he estimated to be 10 years old.
March 3, 2002
: Paterno reports the incident to Athletic Director
, saying the graduate assistant had seen Sandusky "fondling or doing something of a sexual nature to a young boy," according to the grand jury. Later, the assistant is summoned to a meeting with Curley and Senior Vice President for Finance and Business
. The assistant later tells the grand jury he told Curley and Schultz he saw Sandusky and the boy engaged in a sex act, but Curley and Schultz told the grand jury they had not been told of such an allegation. Instead, Curley said he had the impression the conduct amounted to non-sexual "horsing around." Schultz said he couldn't remember details, but seemed to recall that "Sandusky might have inappropriately grabbed the young boy's genitals while wrestling," according to the grand jury. Sandusky's locker room keys are confiscated, he is told not to bring his Second Mile participants to campus and the incident is reported to the charity, but no law enforcement investigation is launched, according to the grand jury.
: The Second Mile learns of the shower incident. Curley tells the charity that "the information had been internally reviewed and that there was no finding of wrongdoing," The Second Mile said in a statement Monday.
2005 or 2006
: Sandusky allegedly befriends another Second Mile participant whose allegations would form the foundation of the multiyear grand jury investigation.
2006 or 2007
: A wrestling coach at the high school where Sandusky was volunteering allegedly surprises Sandusky and the boy "lying on their sides, in physical contact, face to face on a wrestling mat." Sandusky tells the coach the two were working on wrestling moves, the coach tells the grand jury. Sandusky allegedly begins to spend more time with the boy, taking him to sporting events and giving him gifts, including golf clubs, a computer, cash and clothes. During this period, according to the grand jury report, Sandusky performs oral sex on the boy more than 20 times, and the boy performs oral sex on him once.
: The boy's mother calls the high school to report her son had been sexually assaulted, and the principal bars Sandusky from campus and reports the incident to police. The investigation reveals 118 calls from Sandusky's home and cellphone numbers to the boy's home.
: Sandusky informs The Second Mile he is under investigation and he is removed from all program activities involving children, according to the charity.
: Sandusky retires from The Second Mile, according to the grand jury.
: Sandusky is arrested on 40 counts of sexual abuse of children and freed on $100,000 bail. Curley, 57, and Schultz, 62, are each charged with one count of felony perjury and one count of failure to report abuse allegations.
: Curley takes administrative leave to deal with charges. Schultz retires. Penn State President
issues a statement declaring his "unconditional" support of both Curley and Schultz.
: Curley and Schultz are arraigned, remain free on $75,000 bail. Assistant coach
is identified as the graduate assistant who told Paterno about Sandusky's alleged actions. State Police Commissioner Frank Noonan says Paterno and university officials didn't do enough to stop the alleged sexual abuse of children.
: Penn State cancels Paterno's weekly news conference, but he continues to coach. The board of trustees issues a statement saying it is "outraged by the horrifying details" in the grand jury report. The board says it will appoint a committee to investigate the scandal. A crowd of students gathers outside Paterno's home in a show of support. Students outside of Old Main call for Spanier's dismissal.
: Paterno announces in the morning that he will retire at the end of the season and the board of trustees should not spend time discussing his future. The board meets behind closed doors throughout evening and announces at a 10 p.m. news conference that Paterno and Spanier are out. Defensive coordinator
is named interim head coach. Students storm downtown State College, tearing down lampposts and knocking over a news van in protest of Paterno's firing. Police confirm that two people are injured. University sends a text alert demanding students evacuate areas of Old Main and downtown streets.
: Bradley holds his first news conference as head coach, saying he accepted the job with mixed emotions. He says McQueary will be allowed to coach on Saturday. A university spokesman confirms that Spanier was allowed to resign.
