'Horrified' mother of Penn State victim wants 'justice'

University Park, Pennsylvania (CNN) -- The mother of one of the alleged sex abuse victims in the Penn State scandal said she was "absolutely horrified" by the developments and wants the perpetrator "to be put away for a long time."

"I want justice," the mother said on ABC's Good Morning America Friday, making reference to Jerry Sandusky, the former Penn State coach accused of sexually abusing youths.

"I want him to be locked up. There's no help for somebody who does this." Sandusky, who is free on bail, disputes the 23-page grand jury summary of graphic testimony, his attorney said.

Penn State remained embroiled Friday over the child sex abuse that led to the firing of legendary football coach Joe Paterno, with the board of trustees convening and a group of students planning a vigil in support of alleged abuse victims.

The developments come ahead of the team's last home game of the season Saturday against Nebraska.

The university's board of trustees plans to meet Friday morning and is expected to discuss creating a special committee to investigate the child rape allegations, which became public last week after a grand jury report on the case was released.

In the evening, a candlelight vigil in support of victims of child abuse will be held at 9:30 p.m.. There will be speakers, including a victim of sex abuse in another case, performances of the Penn State Blue Band, a marching band, and an a cappella group called Nota. There will be a moment of silence when the clock strikes 10 p.m. at the Old Main building on the Penn State campus.

"We are just as horrified if not more than a lot of people," Kyle Harris, a 21-year-old senior who is one of the organizers said. "We want to make an impact. We want to show these kids we care."

But the controversy revolves around Sandusky, the team's former defensive coordinator who is accused of sexually assaulting children. The mother, whose identity was not disclosed and whose voice was altered, is the parent of Victim 1 in the Pennsylvania grand jury report detailing the accusations.

The report says that the victim was "11 or 12 years old when he met Sandusky through The Second Mile Program in 2005 or 2006." The Second Mile is a charity Sandusky founded to help troubled youths.

The youth had been a "houseguest" at Sandusky's home in Centre County, Pennsylvania.

"During the course of the multi-year investigation, the grand jury heard evidence that Sandusky indecently fondled Victim 1 on a number of occasions, performed oral sex on Victim 1 on a number of occasions and had Victim 1 perform oral sex on him on at least one occasion," the report said.

The mother said he got an inkling about problems when her "son started acting out." She said school counselors told her it was a "puberty thing."

Eventually he told her he wanted to look up information on sexual "weirdos." She asked him why and he said he wanted to see if Sandusky was mentioned.

"I said, 'Well, why would you look him up? And he said, I don't know, he's a weirdo. And I preceded to ask him if there was something he needed to tell me and at that point, he didn't indicate anything."

She called her son's school and asked authorities to talk to him.

"And they did. At that point, they called me and said it was very important that I get there immediately. At that point I already had suspicions. I kind of knew what it was about."

The questioner, George Stephanopoulos, pointed out that this was more than a year after the boy spent more time with Sandusky, when prosecutors asserted that Sandusky "began to abuse the boy." Also, she said, administrators Sandusky had been permitted to take the boy out of class "for unsupervised visits."

She said she didn't know he was removed from classes.

Asked why the boy never told her, she attributes that to "a lot of embarrassment."

"He was giving me hints to figure it out," she said. Years later when they had a "heart-to-heart" conversation, she said her son said he "didn't know what to do."

She said her son told her "you just can't tell Jerry no."

She herself had "no idea" of how something could be happening for so long without it being divulged.

Asked whether she thinks Paterno should be fired, she said "they all needed to be gone."

"The students at Penn State are not involved in hiding this or doing anything to him. So he's really, you know -- he's all cheering for the team. But as far as the people who hid it, no , we have no respect for those people."

In another development, authorities in San Antonio, Texas, are investigating the possibility that Sandusky might have committed sex crimes in 1999 when Penn State played in the Alamo Bowl, CNN affiliates reported. Victim 4 in the Pennsylvania grand jury report had been listed as a member of Sandusky's family party for the bowl game.

Opinion: Ethical lesson of Penn State scandal

Questions over how university officials responded to reports of alleged abuse cost coaching legend Paterno and university President Graham Spanier their jobs. Panterno has been criticized for not calling police, but he has not faced any legal charges.

A graduate assistant at the time and now a coach, Mike McQueary told a grand jury he had witnessed Sandusky, now 67, sexually assaulting the boy at the campus football complex in 2002.

According to a grand jury report, the graduate assistant entered a locker room on a Friday night to stow away some sneakers.

"As the graduate student entered the locker room doors, he was surprised to find the lights and showers on," the grand jury report stated. "He then heard rhythmic, slapping sounds."

The assistant looked into the shower and "saw a naked boy ... whose age he estimated to be 10 years old, with his hands up against the wall, being subjected to anal intercourse by a naked Sandusky," the grand jury report stated.

The graduate assistant reported the incident to Paterno, who in turn alerted Athletic Director Timothy Curley, Pennsylvania Attorney General Linda Kelly said earlier this week.

Kelly said the alleged failure of Curley and Gary Schultz, the university's senior vice president for finance and business, to report abuse claims to authorities "likely allowed a child predator to continue to victimize children for many, many years."

Instead of reporting the incident to authorities, Curley and Schultz banned Sandusky from having children from the charity he founded, Second Mile, visit the football building, Kelly said.

Paterno reported the allegations to his boss. Pennsylvania's attorney general said it appeared Paterno had met his obligations under state law, but critics have said the coach should have reported the suspected abuse to police. That perceived lapse led to the coach's downfall.

McQueary won't be at Saturday's Nebraska game because of "multiple threats," the university athletics website said Thursday night.

Sandusky's lawyer told CNN Thursday evening his client has already been tried in the court of public opinion. Sandusky, who faces child rape charges, disputes the 23-page grand jury summary of graphic testimony, said attorney Joseph Amendola.

Paterno's firing prompted a student riot on campus Wednesday night.

Gov. Tom Corbett decried the violence.

"The eyes of the nation are on you," he reminded residents. "Please behave and demonstrate your pride in Penn State. Your actions speak much louder than your words."

Nebraska athletic director Tom Osborne said Thursday that while he expects fans of both teams to be respectful, he wants to be sure the environment for the visiting Cornhuskers is secure.

"When you have more than 100,000 people in a stadium, it's probably impossible to conjure up enough officials, security people to absolutely guarantee what's going to happen," Osborne told Lincoln, Nebraska, radio station KLIN. "I just don't know how you do that. We will visit with them today and probably tomorrow and do everything within our power to make sure that there's adequate safety and security provided."

Nebraska's chancellor, Harvey Perlman, also released a statement, and expressed sympathy for the alleged victims in the Sandusky case.

"Looking ahead to Saturday's game, others will pour many issues into this football game," Perlman said in a statement. "Nebraska's participation in no way condones the conduct that has been alleged or makes a statement about the truth or falsity of the allegations."

Pennsylvania's U.S. senators, Pat Toomey, a Republican, and Bob Casey, a Democrat, announced that they were rescinding their support for the nomination of Paterno for the Presidential Medal of Freedom.

Sandusky, who was arrested Saturday, is accused of sexual offenses, child endangerment and "corruption of a minor" involving eight boys, most or all of whom he met through The Second Mile, prosecutors said.

His involvement with The Second Mile provided him with access to "hundreds of boys, many of whom were vulnerable due to their social situations," the grand jury said. The former coach is said to have engaged in fondling, oral and anal sex with boys over at least 15 years, according to the investigative grand jury's summary of testimony.

Sandusky served 23 years as defensive coordinator for the Nittany Lions football team before retiring in 1999. Free on $100,000 bail, he has been accused of sexually abusing boys between 1994 and 2009.
