STATE COLLEGE — Penn State’s bill to pay costs associated with the Jerry Sandusky child sex abuse scandal has topped $41 million, including $8.1 million to pay for the internal investigation led by former FBI director Louis Freeh.

The latest disclosure posted Monday on a university website offered more itemization for certain costs including the bill for the Freeh probe. The bill also for the first time includes the $12 million payment to the NCAA — the first of five annual installments of the $60 million fine that’s part of the sanctions.

Penn State also released a copy of its engagement letter with Freeh in December 2011 that details the scope of his responsibilities.
