BELLEFONTE, Pa. — A former Penn State assistant coach who was a central figure in Joe Paterno's downfall testified Tuesday he heard a "skin-on-skin smacking sound" in a campus locker room one night in 2001 and saw something that was "more than my brain could handle."

Jerry Sandusky was standing naked in the showers behind a boy, moving his hips, Mike McQueary told the jury.

McQueary, one of the star witnesses in the child sexual abuse case against ex-Penn State defensive coordinator Sandusky, said he had no doubt he was witnessing anal sex. He testified he slammed his locker shut loudly, as if to say, "Someone's here! Break it up!"

Sandusky, 68, is on trial on charges he molested 10 boys over a 15-year period. Authorities say he abused them in hotels, at his home and inside the football team's quarters. Sandusky, founder of The Second Mile youth charity, has denied the allegations.

Paterno was fired last fall, shortly after Sandusky's arrest, when it became known McQueary had told the coach about the shower episode a decade ago. Two months after his dismissal, Paterno died of lung cancer at 85.

The 37-year-old McQueary, testifying on the second day of Sandusky's trial, walked into the support-staff locker room one night in 2001 and said he saw Sandusky "standing behind a boy who was propped up against a wall." He estimated the boy to be 10 to 12 years old. He said the boy's hands were up on the wall and "the defendant's midsection was moving" subtly.

McQueary, a former Penn State quarterback, said he wasn't sure whether Sandusky saw him. After slamming his locker to make noise, he left.

"It was more than my brain could handle," he said. "I was making decisions on the fly. I picked up the phone and called my father to get advice from the person I trusted most in my life, because I just saw something ridiculous."

McQueary said he went to Paterno's house the next day to relay what he had seen, but did not describe the act explicitly out of respect for the coach and his own embarrassment.

He said Penn State administrator Tim Curley called him a week later, and McQueary met with him and another school official, Gary Schultz. They "just listened to what I had said," McQueary testified. A week or two later, he said, Curley called him to say they had looked into it.

Suspect in killings

surrenders

MONTGOMERY, Ala. — A man accused of killing three people at a party near Auburn University turned himself in after a three-day manhunt that included a fruitless search of a Montgomery home by police tactical units.

A Montgomery defense attorney, Susan James, said she arranged for Desmonte Leonard to surrender after getting word his family wanted her help.

Leonard, 22, is charged with three counts of capital murder in a shooting Saturday after a fight over a woman. He is accused of wounding three others.

The dead included two former Auburn football players — Edward Christian and Ladarious Phillips — and a current Tigers player, offensive lineman Eric Mack, was among the injured.

Court records showed police had arrested Leonard on two previous charges involving guns.
