(CBS/AP) HARRISBURG, Pa. -- Penn State assistant football coach Mike McQueary testified Friday he believes he saw former assistant coach Jerry Sandusky sexually molesting a boy but cannot say he is 100 percent sure it was intercourse.
This is the first time McQueary told his story in a public setting since the Penn State football scandal involving ex-coach Sandusky began.
McQueary said he believes that Sandusky was attacking the child, aged 10 or 12, with his hands around the boy's waist. He said the incident occurred in a Penn State locker room in 2002 and that there was no doubt in his mind that he fully conveyed what he had seen to two Penn State administrators.
Those administrators are now accused of lying to a grand jury about what he told them.
Former Penn State coach Jerry Sandusky says he is innocent of more than 50 counts of sexually abusing 10 boys over a 15-year period.
McQueary said in court today that he truly believes what he saw in a Penn State locker room in 2002 was intercourse. He said the boy was facing the wall with his hands against it. He claimed he peeked into the shower several times and the last time he looked in, Sandusky had separated himself from the boy. He said he didn't any anything but he "knew they saw me. They looked directly in my eye, both of them."
McQueary said he reported what he saw to coach Joe Paterno the next day. He claimed he did not give explicit details of what he believed he'd seen, saying he wouldn't have used terms like "sodomy," or "anal intercourse" out of respect for the longtime coach.
Paterno allegedly told him he had "done the right thing" by telling him, and that he appeared shocked and saddened. He then slumped back in his chair.
In his testimony, McQueary said Paterno told him he would tell others about what he had reportedly seen.
CBS Producer Pat Milton reports McQueary said there was no question that nine or ten days later in 2002, he met with school administrators Tim Curley and Gary Schultz and told them he'd seen Sandusky and a boy, naked, in the shower after hearing skin-on-skin slapping sounds.
"I told them that I saw Jerry in the showers with a young boy and that what I had seen was extremely sexual and over the lines and it was wrong," he said. "I would have described that it was extremely sexual and I thought that some kind of intercourse was going on." He said it was "wrong and over the line."
Both men had appeared to take the reportt seriously, McQueary said. When asked why he didn't go to police, he referenced Shultz's position as the vice president at the university who had overseen the campus police.
"I thought I was talking to the head of police, to be frank with you," he said. "It was someone who police reported to and would know what to do with it."
Both Curley and Schultz are charged with lying to a grand jury and failing to properly report what McQueary had told them. Both men say they are innocent and contest the witness's statements.
District Judge William C. Wenner was hearing testimony Friday to help him decide whether state prosecutors have enough evidence against the pair to send their cases to trial.
