in an interview last night with nbc's bob costas, he admitted to showering with young boys from his second mile charity in the team's locker room. >> okay, we were showering and horsing around and he actually turned all the showers on and was actual lly sliding across t floor. and we were, as i recall, possibly, like, snapping a towel, horseplay. >> reporter: he hesitated when asked if he was sexually attracted to young boys. >> am i sexually attracted to underage boys? sexually attracted, you know, no, i enjoy young people. i love to be around them. i -- i -- but no, i'm not sexually attracted to young boys. >> reporter: tonight, in an abc news exclusive, the mother of one of sandusky's alleged victims spoke out, saying she's disgusted and outraged by sandusky's denials. >> it sickened me that he would

be on tv, trying to downplay his charges and he's just -- i think he made himself look even more guilty. >> reporter: today, the key witness against sandusky, former assistant coach mike mcqueary, was seen shopping in state college, as he prepared to testify that he witnessed a 10-year-old pinned to the team's locker room shower wall in march of 2002, raped by then-coach sandusky. a claim sandusky denied last night. >> i would say that that's false. >> what would be his motive to lie? >> you'd have to ask him that. >> reporter: we did ask him, but he repeatedly declined to comment. >> what is your response -- >> no, sir. >> so what mr. sandusky said last night? >> no thank you. >> reporter: but an e-mail sent to his friends this week, mcqueary for the first time says he told joe paterno about the attack, he told police. according to the associated press, he wrote, "i did stop it. not physically, but made sure it was stopped when i left that locker room.

i did have discussions with police and with the official at the university in charge of police." . sandusky's attorney told abc news today his client wanted to tell the world he's not a pedophile and while he regrets showering with the boys, he's just a jock horsing around in the locker room. >> i think it's important for people to hear jerry sandusky say, i did not assault kids. >> reporter: but speaking publicly may have done more harm than good. >> if he or his lawyer thought that by going public and suggesting, well, it was just showers, it wasn't sexual assault, that was going to somehow help him in the court of public opinion -- they were either crazy or totally deluding themselves. >> reporter: tonight, another allegation of sexual abuse by a penn state faculty member, and again, accusations that the university protected its own, rather than protect the children. paul mclachlan was just 11 years old when he alleges that the

then-penn state childhood development professor sexually abused him over a period of four years, between 1976 and 1980. zbl . >> unfortunately, with predators, that's what they do. they specialize in areas where children, where they have access to children. >> reporter: he says he repressed his memories of the alleged abuse, but in 2002, decided to confront the professor. he claims he recorded conversations where he admitted to performing oral sex on mclachlan. he says when he went to the university about his complaints, he was turned away. >> i was treated with hostility, denials. i was told that my complaints with heresay, despite the fact that i offered them tape-recorded evidence. >> reporter: mclachlan said the penn state authorities refused to even investigation his claim. >> they said they wouldn't be investigating anything of that nature, that this was a respected and important part of penn state and basically how

dare you make such an accusation. >> reporter: he finaled a civil lawsuit, which was settled for an undisclosed amount. the professor retired in 2002 but remained affiliated with the university. penn state officials declined to comment, but it could be a legal nightmare for the school. >> if a plaintiff's lawyer can argue that there was a pattern, that sexual abuse or assault complaints were made to the university and they just sort of disappeared, well, that's a classic civil lawsuit. >> reporter: legend fall and a community reels as police say more victims are coming forward with claims of sexual abuse and cries for help, allegedly ignored. for "nightline," i'm jim avila in state college, pennsylvania. >> what a disturbing and sad story. we'll keep up posted on it. thanks to jim avila. just ahead, we're going to shift gears altogether, take you inside the house that shaq

built. he lets us in on his secret plans for life after basketball.

i think i'm a wise old man right now. >> reporter: well, he has always been something of a wise guy. but he became savvy after magic johnson game him some priceless advice. >> magic pucks me aside and says, you need to start owning things. so, i called my mother, she said, what do you think he's talking about? you ain't going to be able to play ball forever. >> reporter: shaq took that advice to heart and instead of spending his money, he began investing it. in everything from his own shoe line to the five guys burger chain. he's now valued at over $250 million. and he's done it all by being humble. admitting he doesn't always know it all. >> see, i'm big on team work. one thing i've been doing is, i've been teaming up with great people, rather than trying to go make burgers and make fries. if i was in there -- it wouldn't do well. >> reporter: it's all about team work when it comes to shaq. and he's played with them all.

and my father gave him the food. so, when he got back in the car, i'm like, why did you give him my food? and he said, son, if you ever make it, if you ever can help those in need, you'll be all right. >> reporter: the ones in need right now are the workers affected by the nba lockout. >> the president said it the best, said it would be a shame, that if rich people cause regular people to lose their jobs. they're the ones that's going to really be struggling. >> reporter: he's been hired to work as a commentator when and if the basketball season starts. but in the meantime, he's spending his days with his girlfriend, a reality contestant from "flavor of love." >> i think he's on drugs. >> wasn't really taught how to be in a relationship. and now, you know, we're sort of teaching each other. we're learning. we both have a lot of past mistakes we can gol off.
