High-ranking officials at Penn State are accused of giving inconsistent testimony to a grand jury as well as not turning over a secret file containing allegations that Jerry Sandusky was acting inappropriately, according to court documents obtained by CNN.

"The file was created, maintained and possessed by Gary Schultz," according to the document.

Penn State's former vice president for finance and business, Gary Schultz, who also oversaw the college's police department, and former Athletic Director Tim Curley face charges including perjury and failure to report abuse in the scandal. The court documents say the file contains information that is inconsistent with Schultz's and Curley's previous statements to grand jury regarding the Sandusky case.

"The commonwealth has come into possession of computer data (again, subpoenaed long ago but not received from PSU until after the charges had been filed in this case) in the form of e-mails between Schultz, Curley and others that contradict their testimony before the Grand Jury,” the document states.

The motion filed by the attorney general accuses Pennsylvania State University officials of keeping a file with previously unknown details about the child sex abuse allegations against Sandusky. The attorney general's office claims the officials also withheld subpoenaed evidence.

CNN's Susan Candiotti reports that the documents bring up questions about what school officials knew about allegations against Sandusky, when they knew it and what they told authorities during their investigation.

The details emerged on the second day of Sandusky's trial, when the the alleged victim whose allegations triggered the criminal investigation is expected to take the stand. He is one of 10 boys who, prosecutors say, were sexually abused by the Nittany Lions' longtime defensive coordinator over a span of 15 years. Sandusky's trial on 52 charges is expected to continue for about three weeks.
