Mike McQueary, the graduate assistant football coach who allegedly saw Jerry Sandusky sexually abusing a young boy in 2002 and is the one of the key witnesses in the Penn State scandal case, reportedly told a friend in an e-mail that he stopped the act and then went to the police. The e-mail was made available to Associated Press on Tuesday and if true, contradicts his earlier reports.

The comments have further confused a scandal that has resulted in the firing of legendary football coach Joe Paterno, university President Graham Spanier and brought about perjury charges against the athletic director and a senior vice president.

The e-mail, made available on condition of anonymity, stated that McQueary made sure the alleged assault was stopped and even went to the police about it.

I did stop it, not physically ... but made sure it was stopped when I left that locker room ... I did have discussions with police and with the official at the university in charge of police .... no one can imagine my thoughts or wants to be in my shoes for those 30-45 seconds ... trust me, wrote McQueary, who is currently on paid administrative leave.

According to the grand jury indictment, however, McQueary testified that when he witnessed the incident he first consulted his own father and then spoke to Paterno, who said he passed the information onto A.D. Tim Curley and S.V.P. Gary Schultz.

McQueary's latest comments have come less than a day after Sandusky, a longtime defensive coordinator, admitted on NBC News' Rock Center that he showered and horsed around with pre-teen boys. However, he insisted that he was not a pedophile.

Sandusky is charged with 40 counts of sexually abusing eight boys for over a span of 15 years.

Do with this what you want ... but I am getting hammered for handling this the right way ... or what I thought at the time was right ... I had to make tough impacting quick decisions, wrote McQueary in the e-mail.
