The case against Sandusky has has roiled the Penn State campus. Football coach Joe Paterno and the university's president have both been fired, two other top officials have been charged with perjury and failure to report sex abuse, and a coach who allegedly witnessed a 2002 rape in a locker room shower has been put on leave.
Sandusky is fighting back. His lawyer told ABC News Tuesday that the boy who was allegedly raped in the shower has said he never molested.
"The kid is... now grown up, he's in his 20s. He's adamant that nothing sexual occurred," lawyer Joe Amendola said.
Amendola said he expects other boys among the eight in the grand jury report will also contest those claims.
On the same day, however, an assistant coach who the report states saw the rape sent an email to a friend suggesting he did witness a sexual act and that he intervened to stop it.
"I did stop it, not physically ... but made sure it was stopped when I left that locker room," Mike McQueary wrote in his email.
McQueary also wrote that he spoke to police about the alleged assault. The grand jury report states that no one at the school ever notified police about the rape allegation.
McQueary is refusing to react publicly to Sandusky calling his testimony about what he says he witnessed in the shower a lie. When ABC News asked if he would be willing to make a statement about Sandusky's allegations, McQueary simply said "no sir."
