Jerry Sandusky's actions with children were branded those likely to fit a "pedophile's pattern" a psychologist concluded in 1998, a shocking report by NBC News has revealed.

The former Penn State assistant football coach has been charged with raping and otherwise molesting dozens of male children, and it appears the University did not act at all on the psychologist's warning more than a decade before most of the alleged crimes occurred.

Joe Paterno is finally speaking out about the sex abuse scandal that has embroiled Penn State for the last several months, costing him the job of head football coach.

Paterno's former assistant coach Jerry Sandusky is facing more than 50 counts of sexually abusing minor boys, with the allegations ranging from rape to inappropriate touching.

The university's athletic director and vice president have also been charged with lying to the grand jury investigating the allegations again Sandusky,

In a blockbuster exclusive with The Washington Post Paterno said he first learned there was a problem with Sandusky a decade ago when a young assistant, Mike McQueary, told him he'd witnessed Sandusky abusing a young boy in a shower.

“He was very upset and I said why, and he was very reluctant to get into it,” Paterno told The Post in his first interview about the case.

"He told me what he saw, and I said, what? He said it, well, looked like inappropriate, or fondling, I’m not quite sure exactly how he put it. I said you did what you had to do. It’s my job now to figure out what we want to do. So I sat around. It was a Saturday. Waited till Sunday because I wanted to make sure I knew what I was doing. And then I called my superiors and I said: ‘Hey, we got a problem, I think. Would you guys look into it?’ Cause I didn’t know, you know. We never had, until that point, 58 years I think, I had never had to deal with something like that. And I didn’t feel adequate.”

Paterno, who is now 85 and battling cancer, added that he didn't know what university procedure was in a situation like this. “So I backed away and turned it over to some other people, people I thought would have a little more expertise than I did. It didn’t work out that way.”

Paterno insisted that McQueary was unclear with him about the nature of what he saw, and added that even if McQueary had been more graphic, he’s not sure he would have understood.

“You know, he didn’t want to get specific,” Paterno told The Post. “And to be frank with you I don’t know that it would have done any good, because I never heard of, of, rape and a man. So I just did what I thought was best. I talked to people that I thought would be, if there was a problem, that would be following up on it.”

Paterno has not been charged with any crime, and now admits, "I wish I had done more."

Penn State assistant football coach Mike McQueary testified Friday in a Pennsylvania courtroom that he saw Jerry Sandusky acting “extremely sexual” with a boy in a shower in a Penn State locker room one evening back in 2002.

McQueary spoke publicly for the first time about the incident at the preliminary hearing for two Penn State officials, Tim Curley, 57, and Gary Schultz, 62, who are accused of covering up Sandusky’s crimes.

In court, McQueary said he believes Sandusky, also an assistant coach at the time, was sexually molesting the boy, but said he wasn't 100 percent sure it was intercourse.

In graphic detail, McQueary, 27, testified that he saw Sandusky, 67, with his hands around the boy's waist. He said the boy was facing a wall, with his hands on it.

Claims made by a key witness in the Penn State sex abuse scandal are being disputed by police investigating the shocking case, RadarOnline.com has learned.

Mike McQueary told a friend that he had informed the police about Jerry Sandusky's assaults on young boys, but both the university's campus police and the State College police department say they never received reports from the then-Penn State graduate assistant, reported CBSNews.com on Wednesday.

In an e-mail written by McQueary on November 8, he said he had discussions with police after he said he witnessed a 10 or 11-year-old boy being raped in the Penn State locker room in 2002. McQueary testified in a grand jury investigation that led to authorities charging Sandusky with abusing eight boys over 15 years.
