The internal probe of a possible sex abuse cover-up at Penn State is wrapping up, with the results to be released Thursday.

FOX News Radio's Lisa Brady reports:

Penn State's trustees ordered the internal investigation after Jerry Sandusky's arrest, billing it as the search for who knew what, when, about the child sex abuse allegations against the former assistant coach, who's since been convicted on 45 counts.

While he awaits sentencing, criminal cases continue against two school administrators - one now retired, the other on leave.  The school's conduct, also under NCAA review.  Former FBI Director Louis Freeh led the Penn State investigation, which includes coach Joe Paterno's response.
