(CNN) - 1977 - Penn State football defensive coordinator Jerry Sandusky founds the Second Mile, a charity to help troubled youths.
1994-97 - According to the grand jury report, Sandusky allegedly engages in inappropriate conduct with three different boys he met separately through the Second Mile program. One boy was 7 or 8, another was 10, and the third was 12 or 13 at the time. According to the grand jury report, the now-adult men said Sandusky engaged in inappropriate conduct ranging from touching to outright sexual encounters, including several incidents during the nights before Penn State football home games, when the team, staff and boys Sandusky had allegedly invited were staying at a hotel.
1998 - Penn State police and the Pennsylvania Department of Public Welfare investigate an incident in which the mother of an 11-year-old boy reported that Sandusky had showered with her son and may have had inappropriate conduct with him. In a June 1, 1998, interview with investigators from both agencies, Sandusky admits showering naked with the boy, admitting that it was wrong and promising not to do it again, according to the grand jury report. The district attorney advises investigators that no charges will be filed and the university police chief instructs that the case be closed, according to the testimony included in the grand jury report from the police detective who investigated the incident.
