( CNN ) -- Former FBI Director Louis Freeh will lead an independent inquiry for Penn State University into the school 's response to child sex abuse allegations , trustee Kenneth Frazier said Monday . `` No one -- no one -- is above scrutiny , including every member of the administration of the university , every member of our board of trustees , and every employee of the university , '' said Frazier , who was appointed to chair the special investigative committee into the university 's response to allegations involving former assistant football coach Jerry Sandusky . A grand jury reported this month that university officials allegedly knew of allegations of misconduct on Sandusky 's part , but failed to fully act on them . Freeh , who will serve as special investigative counsel , said he extracted pledges of support and non-interference from university officials before taking on the job . `` This assurance is the main condition of my engagement , '' he said . He said will appoint a team of former FBI agents and former federal prosecutors from his law firm to assist . Results of the investigation will be released to trustees and the public at about the same time , he said . It 's unclear how effective Freeh will be , said CNN senior legal analyst Jeffrey Toobin . `` Louis Freeh is an honorable person , but the question is whether he will have the tools to do a thorough investigation . '' Toobin said . With police , the university and even Sandusky 's former charity , The Second Mile , conducting their own investigations , it 's unclear whether witnesses will want to repeat their stories over and over again , he said . At the heart of the scandal are accusations that Sandusky , the retired defensive coordinator for the Penn State football team , sexually abused a boy at the university football complex , and that law enforcement officials were not notified . According to grand jury documents , a graduate assistant told head football coach Joe Paterno in 2002 that he had seen Sandusky performing anal sex on a young boy in a football complex shower . Paterno told athletic director Tim Curley , who told Gary Schultz , a university vice president . Some information about the allegations eventually reached President Graham Spanier , according to the grand jury . Paterno has said he did `` what I was supposed to do . '' But in a later statement , he said `` with the benefit of hindsight , I wish I had done more . '' While it took years for the alleged abuse to become public , school officials moved quickly after prosecutors charged Sandusky , 67 , with 40 counts in the alleged sexual abuse of eight young boys over several years . Authorities also charged Curley and Schultz with misleading the grand jury investigating the allegations and failing to report suspected abuse . Curley and Schultz stepped aside within a day of the charges , and before the week was out , trustees had fired both Paterno -- the winningest football coach in Division I history -- and Spanier . The university 's special committee , created six days after Sandusky 's arrest , empowered Freeh to `` take his team 's work to wherever it leads , '' Frazier said . The NCAA and the U.S. Department of Education are also investigating the university 's response . Freeh said he did not know how much the investigation will cost , or how long it will take , other than that it will be lengthy . Investigators had already begun work reviewing documents in the case , he said . While he does not have the subpoena power he enjoyed as an FBI official , Freeh said he is counting on the cooperation of law enforcement and the Penn State community , which is eager to restore the university 's reputation . `` In my current role , I will encourage everyone to speak to us , '' he said . Frazier said the scandal has caused irreparable harm to the school , but officials are determined to make sure it never happens again . `` Words alone can not express the heartbreak and sorrow we feel for the victims , '' he said .
