him. hers by birth, his first as a foster child and at age 18, adopted as an adult. after a relationship that began when matt was just 10 years old. >> when it first started, you could see that he was, like, excited to see jerry show up. and as it progressed, it got to the point where he would look out the window, see jerry pull in and hide behind a bedroom door. >> reporter: matt has said publicly he was never molested and to this day has aligned with his adopted father. but his mother does not believe it and says coach sandusky stole her son's affections from her with the same predatory skills prosecutors say he used on eight alleged victims of sexual assault. meeting her son at the children's charity, second mile, mentoring him. a mom giving insight into what she and prosecutors contend are sandusky's grooming techniques. >> it was jerry sandusky. any 10-year-old kid is going to be impressed by penn state

football. it's a game here or a picnic there. penn state jackets and athletic wear and shorts and money. every -- >> reporter: trips? >> yeah, everybody that a kid would dream of. >> reporter: but for this mother, watching her child slip away, sent to sandusky's foster care after a boy vandalized a garage, not sure what was happening to him. it was a different kind of dream. how scary is it for a mom? >> oh, it's a nightmare. nobody even wants to think that somebody would do that to their child. and then so many adults knew about it and did nothing. how is that right? >> reporter: it is the same method this mother says sandusky used with her son. but her boy, alleged victim number one, says he was molested by sandusky and abc news has learned that he, along with another of the eight alleged victims, identified in the indictment paperwork, are now prepared to testify against sandusky in court.

is your son anxious to testify against him? >> he's scared but he's anxious. he's ready. he wants to do it. he wants him to go to jail and he wants him to pay for what he's done. >> reporter: the other boy ready to testify is represented by ben an dree owe si. >> he's not going anywhere. he intends to testify. >> reporter: the attorney says until sandusky tried to minimize his conduct on national tv this week, his client was only on the fence about testifying. but now -- >> when he's called upon by the attorney general's office to testify in the criminal case, he'll be prepared. >> reporter: those two alleged victims will join coach mike mcqueary as the key witnesses against sandusky. mcqueary says he interrupted a brutal attack by sandusky on a 10-year-old in the penn state locker room shower area. mcqueary already testified in front of a grand jury and that panel found his credible. >> in this circumstance, you have a group, again, a group of

jurors that are were unequivocal in saying mcyear rip's testimony was very credible. the prosecutors are hoching that when they present that testimony to a, what we call a pettitte jury, that they will feel the same way. >> reporter: the former d.a. has a brother-in-law adopted by jerry sandusky. so when the charges first came to his office in 2009, he saw that they were serious and turned the file over to the state attorney general, claiming conflict of interest. and even now he is shocked at what he sees as a pattern of ape abuse that was allowed to go on at one of america's finest institutions. you look at what happened in this case, where officials were informed and they didn't go to police, that surprise you? >> yes, it does. my visceral reaction to that is, how can you know what we now know is alleged you were told and not have done something more

with it? indeed, how can you know in 2000 or 2002, you're away of three incidents and not have done something about it. >> reporter: eight cases and perhaps more to come, in over a decade of time, by a man prosecutors contend used his position, power and the attraction of big-time college football, in what many are now calling the biggest scandal in sports history. that pe at penn state university, i'm jim avila for "nightline." >> a tragedy that just keeps going. just ahead, what does justin bieber and hallie berry have in common? we sniff out an answer.

world that they see around them and want something else to be there. i'm really sort of baffled. i don't get it. >> reporter: is their search for something, anything, inevitable in an increasingly godless society? or, as some say, are we reading too many spooky novels? watching too many ghostly carto cartoons, tv shows? >> got a slight increase in the elect electromagnetic field around here. >> reporter: no one can prove ghosts don't exist. >> we've gathered paranormal evidence here in terms of, again, temperature pluck raxs, people have been touched. >> reporter: but not even barri has proved that ghosts do exist. >> i don't think i'm going to find ultimate proof even before i die. i'm just going to carry on. when inpass away, i'm going to come back and get proof. >> reporter: i'm nick watt for "nightline" in the hell fire caves, england.
