http://www.nytimes.com/2011/11/17/s...sandusky-investigators.html?pagewanted=1&_r=1 Working off the brief mention on an Internet forum where people chatted about Penn State athletics, according to the two people with knowledge of the case, investigators narrowed their list of coaches likely to have seen something to Mike McQueary, then an assistant coach and the football program’s recruiting coordinator.
State College is a close-knit community. Word would get around that a Penn State coach had met with investigators. So investigators set up a meeting in an out-of-the-way parking lot, according to those with knowledge of the case.
There, one day a little over a year ago, McQueary unburdened himself, the two people said. He needed little prompting.
He told of a horrific scene he had stumbled upon as a graduate assistant one Friday night in March 2002: a naked boy, about 10, hands pressed against the locker room wall of the Lasch Football Building, being raped by Sandusky. McQueary was explicit and unequivocal, the people said. He had told Paterno, the team’s longtime and widely beloved head coach, about the incident the next day, but he was filled with regret that nothing had happened.
“This had been weighing on him for a very long time, and our guys felt he was relieved to get it off his chest,” one law enforcement official said. “When he had the opportunity to make it right, he told the truth.”
