University Park , Pennsylvania -LRB- CNN -RRB- -- The Penn State football coach who alerted head coach Joe Paterno in 2002 that he 'd seen a former defensive coordinator sexually assault a boy -- an allegation authorities did n't learn of until years later -- was placed Friday on indefinite leave , the school 's interim president said . With that , Mike McQueary became the latest casualty in a scandal that began with last week 's arrest of the man he allegedly witnessed commit the crime . The arrest set off a chain of events , including the ouster of the university 's president and of longtime coach Paterno , a move that sparked on-campus riots after it was announced Wednesday . McQueary in recent months told a grand jury that , when he was a graduate assistant , he saw Jerry Sandusky , now 67 , sexually assault a young boy at the campus ' football complex . He said he reported the incident to Paterno , who alerted Athletic Director Timothy Curley , Pennsylvania Attorney General Linda Kelly said earlier this week . Neither Paterno , 84 , nor McQueary is criminally charged . Kelly has said that the alleged failure of Curley and Gary Schultz , the university 's senior vice president for finance and business , to tell authorities about McQueary 's abuse claim `` likely allowed a child predator to continue to victimize children for many , many years . '' On Friday , acting President Rodney Erickson announced that he and newly named Athletic Director Mark Sherburne had decided to put McQueary on administrative leave . A day earlier , the school athletic department said McQueary would not coach in Saturday 's game against Nebraska due to `` multiple threats '' against him . `` It became clear that Coach McQueary could not function in this role , under these circumstances , '' Erickson said of the decision . Sandusky , the football team 's defensive coordinator between 1977 and 1999 , was taken into custody Saturday for allegedly sexually assaulting children . Sandusky , who is free on $ 100,000 bail , disputes the 23-page grand jury summary of graphic testimony describing the alleged crimes between 1994 and 2009 , his attorney , Joseph Amendola , has said . On Friday , the lawyer told CNN that a rock had been thrown through a window at Sandusky 's home . The scandal has stirred an uproar and a flurry of action over how Penn State athletic and administrative officials handled the matter . Erickson said Friday that he 'll appoint an ethics officer to report directly to him . He added that he wants to encourage openness and dialogue among the school 's 96,000 students so that they do not hesitate to report such allegations . `` Never again should anyone at Penn State -- regardless of their position -- feel scared to do the right thing , '' he said . Earlier , he announced the creation of a committee to review sexual abuse allegations at the school -- an inquiry that its chairman , Kenneth Frazier , promised Friday would be `` rigorous , objective and impartial . '' State Education Secretary Ronald Tomalis will serve as vice chairman , it was announced at a board meeting . Erickson 's predecessor was Graham Spanier , who initially had voiced support for Curley and Schultz and later was removed from office by a unanimous vote of the board of trustees . A senior Navy official told CNN on Friday that , `` based on the events this week at Penn State , Navy officials are reviewing '' Spanier 's membership on the board of advisers at the Naval Postgraduate School in Monterey , California . The 18 members of the federal advisory committee are nominated to four-year terms . A recommendation to renominate Spanier had been in the works , but will likely be pulled back , the Navy official said . Meanwhile , students held a candlelight vigil Friday night on the University Park campus -- the same place where , two days earlier , others rioted after the university 's trustees fired Paterno . The vigil is one of several efforts aimed at bringing attention to child sexual abuse . `` We are just as horrified , if not more , than a lot of people , '' said senior Kyle Harris , 21 , a vigil organizer . `` We want to make an impact . We want to show these kids we care . '' Friday 's event , which began at 9:30 p.m. , included comments from a sex abuse victim , musical performances and a moment of silence as the clock struck 10 p.m. at the campus ' Old Main building . The Foundation to Abolish Child Abuse is planning its own vigil between 4 and 6 p.m. Saturday in support of victims/survivors of childhood sexual abuse . Warning signs of sexual abuse Michael Gillum , the psychologist for the person referred to as `` Victim 1 '' in the Pennsylvania grand jury report , told CNN 's Anderson Cooper on Friday night he was `` stunned '' that so many individuals , after witnessing or hearing allegations about Sandusky , did not come forward sooner . The report says that Gillum 's patient 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 . Gillum said that people should understand `` the powerful differential between the victim and the perpetrator , '' adding that `` the more status the perpetrator has ... the more difficult it is for the victim to come forward , and , in particular , expect to be believed . '' Anxiety , depression and fear of being found out are common among sex abuse victims , especially when the cases go public , the psychologist said . `` Even though he 's a hero -LRB- for speaking up -RRB- , it 's not necessarily something that everyone understands and appreciates , '' Gillum said . The victim 's mother told ABC 's `` Good Morning America '' earlier Friday that she first got an inkling that something had happened when her `` son started acting out '' -- behavior that school counselors had dismissed as a `` puberty thing . '' Eventually , he told her he wanted to look up information on sexual `` weirdos . '' She said she asked him why , and he told her he wanted to see if Sandusky was mentioned . `` I said , ` Well , why would you look him up ? ' And he said , ' I do n'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 did n't indicate anything . '' Read the grand jury presentment . Warning : graphic content -LRB- PDF -RRB- Years later , when they had a `` heart-to-heart '' conversation , the woman said her son said he `` did n't know what to do . '' `` You just ca n't tell Jerry no , '' the boy said , according to the mother . The accusations may extend beyond Pennsylvania . Authorities in San Antonio , Texas , said they are investigating the possibility that Sandusky may have committed sex crimes in 1999 when Penn State played in the Alamo Bowl . `` Victim 4 '' in the grand jury report was identified as a member of Sandusky 's family party for the bowl game . Opinion : Ethical lesson of Penn State scandal Sandusky 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 , the charity he founded , 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 and oral and anal sex with boys over at least 15 years , the grand jury 's summary of testimony says . Curley and Schultz are criminally charged for failing to report the alleged abuse . Instead of reporting the 2002 shower incident to authorities , Curley and Schultz banned Sandusky from having children from The Second Mile visit the football building , Kelly said . With a record of 8-1 , Penn State is ranked atop the Big Ten and is ranked No. 12 in the country , potentially in position to play in a premier Bowl Championship Series contest . The team faces the 19th-ranked Cornhuskers in a game set to begin at noon Saturday at Beaver Stadium . Erickson said Friday that it would `` not be fair '' to cancel Saturday 's game , given that `` our student-athletes were n't involved in this situation '' and thus do n't deserve to be penalized . On Friday night , the school issued a statement urging attendees not only to wear blue to raise awareness of child abuse , but to donate to Prevent Child Abuse Pennsylvania and the Pennsylvania Coalition Against Rape . Erickson said Friday that extra security would be in place for the contest , which the school said would mean `` strict '' enforcement on policies regarding bags being taken into the stadium . `` I hope and I believe we will see the best of our students tomorrow , '' Erickson said . `` They understand that Penn State is really in the spotlight .
