An attorney representing former Penn State athletic director Tim Curley argued Thursday that prosecutors had lodged an “unorthodox” perjury case against her client regarding a conclusion he made about allegations involving convicted serial child-sex abuser Jerry Sandusky.

At an hour-long pretrial motions hearing in Harrisburg, attorney Caroline Roberto said Curley simply drew an earnest conclusion about statements former graduate assistant Mike McQueary made to Curley regarding the 2001 shower incident between Sandusky and a boy known as Victim 2, and conveyed that to a grand jury.
