Under cross-examination, the accuser said he and a friend went to a football game in autumn 2011, accompanied by Sandusky, because the friend of the teen had never been to a football game.

Earlier, a police officer testified that he investigated after a woman reported Sandusky had showered with her son in 1998. He said he felt charges should have been filed against Sandusky then, but prosecutors at the time did not agree.

Ronald Schreffler, a former Penn State police investigator who now works for the Department of Homeland Security, said he was among officers hiding in the woman's home when she confronted Sandusky about her suspicions regarding inappropriate behavior with her son, identified as Alleged Victim 6.

He testified he heard Sandusky tell her: "I wish I could ask forgiveness. I know I can't get it from you. I wish I were dead."

Another witnesses, Anthony Sassano, an agent with the state attorney general's office, testified photos of some of the accusers were found in a photo album during a June 2011 search of the defendant's house. A list of those who participated in camps put on by Second Mile also was found in the residence, according to Sassano.

Sassano said he found in Sandusky's abandoned Penn State office lists of Second Mile children with notations next to the names of some of the alleged victims.

Sandusky, longtime defensive coordinator for the Nittany Lions, faces 52 counts tied to what prosecutors say was his systematic abuse of at least 10 boys over a span of 15 years. Now 68, Sandusky has been under house arrest in the days leading up to his trial. He has pleaded not guilty and has maintained his contact with children was not sexual.

Another witness, Alleged Victim 3, testified Thursday that Sandusky would touch him inappropriately during showers and overnight stays at the former Penn State coach's home.

He testified that he was part of Second Mile and that he stayed overnight at Sandusky's home "more than 50 times." Sandusky often came downstairs where he was sleeping, he said.

"He would ask me why I would want to sleep with all my clothes on, so eventually I'd be stripped down to my underwear," said the man, now 25. "He'd jump into bed with me, start tickling me, blowing on my stomach and pelvis. He would also, at times, touch my penis."

Asked if he told Sandusky to stop, he said, "No. I was enjoying the things I was getting too much," referencing trips to football games and favors from Sandusky. "He made me feel like I was part of something, like a family," he said. "He gave me things that I had never had before. ... I loved him."

He said he never told anyone about his experiences. Eventually, he said, he was sent to group homes, then foster care.

"He never contacted me," he said of Sandusky, saying he was angry "because he could just forget about me, like I was nothing, after all that."

By 1999, as a 12-year-old, he testified, he was uncomfortable with the contact. "I would roll over (in bed) and try to get away from him," he said. "That's pretty much where it would stop; I wouldn't let it go any further."

Alleged Victim 6 testified about the 1998 incident, when he was 11, that triggered a police investigation. After working out with Sandusky at Penn State, he told jurors he recalled feeling uncomfortable while showering with Sandusky.

He said that when both were naked, he started to shower across the room from Sandusky. "I didn't want to be right next to him in the shower. I felt really awkward with that situation." But, he said, Sandusky told him to come over next to him, then began tickling him.

"I believe at one point he grabbed me from behind and gave me a big bear hug. ... He said, 'I'm going to squeeze your guts out.' I remember seeing his chest hair right in my face, and thinking, 'This is icky.' "

He remembered Sandusky helped wash him and told him, " 'Let me help you with your back, where you can't reach.' ... It was just escalating, the uncomfortableness of it."

He testified that he cannot remember anything, even the trip home, after Sandusky lifted him up to the shower head to get the shampoo out of his hair. "It's just kind of black," he said.

When he got home, he said he told his mother: "'By the way, if you see my hair is wet, it's because we took a shower," adding, "She knew who I took a shower with. I told her bits and pieces, but not about everything that happened."
