But McQueary added, "There's no question in my mind that I conveyed to (university officials) that I saw Jerry with a boy in the shower and that it was severe sexual acts going on and that it was wrong and over the line."
He further testified he did not alert police, saying that he instead told Curley and Schultz.
"In my mind, that is the police," McQueary said. "I want to make that clear."
When pressed about why he went to university officials and not police, McQueary said it was "because it was delicate in nature and I tried to use my best judgment."
Sandusky, who was Penn State's defensive coordinator when he retired in 1998, met his accusers through a youth charity he founded, the Second Mile. According to prosecutors, he would hug, tickle and wrestle with the boys before allegedly crossing the line and sexually abusing them.
In November, the summary of a grand jury report was released contending that Sandusky sexually abused the boys in the basement of his home, hotel rooms, a high school wrestling room and -- based on McQueary's account -- the locker room for Penn State's football team.
Sandusky waived his right to a preliminary hearing Tuesday in Centre County, a two-hour drive from Harrisburg. From the courthouse's steps, his attorney, Joseph Amendola, took shots at McQueary's credibility during a long talk with reporters.
He suggested that had McQueary told Paterno, Curley and Schultz that he had seen Sandusky raping a boy in the showers, they would have done more than order him to stop bringing Second Mile children on campus.
