HARRISBURG, Pa. (AP) -- The three former Penn State administrators charged with a criminal cover-up of the Jerry Sandusky child molestation scandal want prosecutors to produce more details about the allegations they face.
Three sets of requests for ''bills of particulars'' were filed Friday in Dauphin County court by lawyers for Graham Spanier, Tim Curley and Gary Schultz.
The three men are awaiting trial on allegations that include perjury, obstruction and conspiracy, accused of hiding evidence from investigators and lying to the grand jury. Spanier is the university's former president, while Curley has retired as athletic director and Schultz has retired as vice president.
The requests seek information that includes exact times, dates and places where crimes are alleged to have occurred, for example. All three argued the additional information is needed in order to formulate a defense.
''The criminal information alleges that the crimes occurred over an 11-year period of time - from February 2001 to Oct. 31, 2012,'' wrote Curley's lawyer, Caroline Roberto. ''As such, identification of the particular allegations is necessary to enable Mr. Curley to prepare a defense, to adequately prepare for trial and to avoid unfair surprise at the time of trial.''
Prosecutors allege the men covered up abuse allegations involving the former Penn State assistant football coach. Sandusky is serving a 30- to 60-year state prison sentence for sexual abuse of 10 boys and is pursuing appeals.
Joe Peters, a spokesman for the attorney general's office, said the requests were unusual and declined to say precisely what prosecutors were prepared to disclose.
''We always attempt to provide not only everything that we are legally obligated to provide, but if there are additional things to aid in the defense so there is a fair trial, we will do that,'' Peters said Monday.
Roberto and Schultz's lawyer declined comment, while attorneys for Spanier did not respond to messages.
