A Penn State investigation into whether university officials helped cover up that Jerry Sandusky was molesting children will be released Thursday.

The review is being led by former FBI director and federal judge Louis Freeh. Freeh on Tuesday announced the timeframe for the release of the report.

The report was commissioned by university trustees in November, about two weeks after the former assistant football coach was arrested on molestation charges.

The study is expected to disclose what occurred within the university, including any role longtime head coach Joe Paterno may have played when school officials fielded complaints about Sandusky in 1998 and 2001. Paterno was fired in the wake of his former assistant's arrest and died in January.

Trustee Ken Frazier has said the goal was to find out "who knew what, when," and to make recommendations for policy and procedural changes.
