Jerry Sandusky, a former defensive coordinator under Joe Paterno at Penn State, was convicted in June 2012 of 45 of 48 counts of molesting 10 boys in a 15-year period. Sandusky was arrested in November 2011 after a grand jury report found that Sandusky, who retired in 1999 but retained access to Penn State's facilities, was seen in 2002 sexually assaulting a 10-year-old boy. The incident allegedly was witnessed by then-graduate assistant Mike McQueary, who reported it to Paterno. Paterno then reported the allegations to Penn State athletic director Tim Curley.

McQueary, Paterno, Curley and Penn State senior vice president Gary Schultz all testified as part of the grand jury investigation into Sandusky. The grand jury found that Curley and Schultz were not credible, and they were charged with perjury and failure to report suspected child abuse. According to the indictment, they failed to inform police of the situation, and they told the grand jury that McQueary never informed them of what he saw.

On Nov. 6, 2011, Sandusky was officially banned from the Penn State campus. Schultz resigned, and Curley took a leave of absence. Three days later, Penn State's board of trustees forced university president Graham Spanier to resign, and Paterno -- who earlier in the day had announced he would retire at the end of the season -- was fired.

Sandusky went on trial on June 5, 2012. The trial, including jury selection, lasted a little more than two weeks. Four of the 52 counts Sandusky originally faced were thrown out during the course of the trial. On June 22, Sandusky was convicted of 45 of the 48 remaining counts. He was sentenced to at least 30 years in prison.
