A Penn State assistant football coach testified Friday that he believes he saw former assistant coach Jerry Sandusky molesting a boy and that he fully conveyed what he had seen to two Penn State administrators.

Mike McQueary, speaking for the first time in public about the 2002 encounter in a Penn State locker room, said he believes that Sandusky was attacking the child with his hands around the boy’s waist but said he wasn’t 100 percent sure it was intercourse.

McQueary took the stand in a Pennsylvania courtroom during a preliminary hearing for university officials Tim Curley and Gary Schultz, who are accused of lying to a grand jury about what McQueary told them. At the conclusion of the hearing, District Judge William C. Wenner ruled that prosecutors have enough evidence to send their cases to trial.

McQueary’s story is central to the case against Curley and Schultz. They testified to the grand jury that McQueary never relayed the seriousness of what he saw. The officials, and former Penn State coach Joe Paterno, have been criticized for never telling police about the 2002 allegation.

The lawyers for Curley and Schultz say the men are innocent and that uncorroborated testimony from McQueary is not enough on which to hang the case. Curley and Schultz told the grand jury that they remembered McQueary reporting only something inappropriate, like wrestling, but nothing as serious as rape.

McQueary, who was on the stand for about two hours Friday, said he had stopped by a campus football locker room to drop off a pair of sneakers in the spring of 2002 when he heard slapping sounds in a shower and happened upon Sandusky and the boy.

He said Sandusky was behind the boy he estimated to be 10 or 12 years old, with his hands wrapped around the youngster’s waist. He said the boy was facing a wall, with his hands on it.

McQueary, 37, said he has never described what he saw as anal rape or intercourse and couldn’t see Sandusky’s genitals, but that “it was very clear that it looked like there was intercourse going on.”

Under cross examination by an attorney for Curley, McQueary reiterated that he had not seen Sandusky penetrating or fondling the boy but was nearly certain they were having intercourse because the two were standing so close and Sandusky’s arms were wrapped around the youth.

He said he peeked into the shower three times — the first via a mirror, the other two times directly. The last time he looked in, Sandusky and the boy had separated, he said. He said he didn’t say anything, but “I know they saw me. They looked directly in my eye, both of them.”
