Spanier, who remains a PSU faculty member, was forced to step down as president after Sandusky, an ex football coach, was arrested and charged with sexually assaulting boys, some of them on campus.

The NBC report, citing unnamed sources, said investigators have 2001 emails among Spanier, school official Gary Schultz and athletic director Tim Curley that allegedly show they opted not to contact authorities about abuse allegations related to Sandusky. The emails reportedly say officials thought that would be the "humane" way to handle the situation.

. They have left their Penn State posts.

UPDATE: A statement today from Schultz and Curley attorneys: "The information confirms that as they testified at the grand jury, Tim Curley and Gary Schultz conscientiously considered Mike McQueary's reports of observing inappropriate conduct, reported it to the University President Graham Spanier, and deliberated about how to responsibly deal with the conduct and handle the situation properly."

UPDATE: David La Torre, PSU spokesman, said, "In the course of former FBI Director Louis Freeh's independent investigation, emails were discovered and immediately turned over to the state attorney general. In deference to the legal process, the university cannot comment further on specifics of the ongoing legal case as it unfolds. We continue to work with the state attorney general, the U.S. attorney and Judge Freeh in their investigations into this matter. We will continue to cooperate fully with all legal processes to determine what happened and ensure personal accountability."

Sandusky, 68, faces 52 counts that he sexually abused 10 boys over 15 years, allegations he has denied. His trial started this morning in the Centre County Courthouse.
