In 1998, the Penn State campus police and local law enforcement authorities investigated an allegation that Jerry Sandusky, then a prominent coach with the university’s football team, had engaged in inappropriate and perhaps sexual conduct with a boy in the football facility’s showers.

A lengthy police report was generated, state prosecutors said. The boy was interviewed. A second potential victim was identified. Child welfare authorities were brought in. Sandusky confessed to showering with one or both of the children. The local district attorney was given material to consider prosecution.

In the end, no prosecution was undertaken. The child welfare agency did not take action. And, according to prosecutors, the commander of the university’s campus police force told his detective, Ronald Schreffler, to close the case.

“Sandusky admitted showering naked with Victim 6, admitted to hugging Victim 6 while in the shower and admitted that it was wrong,” said the report issued last weekend by the Pennsylvania attorney general. “Detective Schreffler advised Sandusky not to shower with any child again and Sandusky said that he would not.”
