BELLEFONTE, Pa. — Allegations that a beloved icon of Penn State's football team has secretly been a serial molester are getting their first legal test in a central Pennsylvania courtroom.

State prosecutors will have to prove Tuesday they have enough evidence to advance the case against Jerry Sandusky to Centre County court for trial.

Young men who've said Sandusky sexually abused them when they were boys are expected to testify in his preliminary hearing on more than 50 criminal counts. The hearing is expected to last a day or more.

Sandusky, 67, denies the allegations against him. He can waive the preliminary hearing, but his lawyer says he wants to lock witnesses into testimony and learn more details about the government's case.
