Erickson answered questions from alumni unhappy about how the school handled a child sex abuse scandal, the firing of longtime football coach Joe Paterno and a lack of transparency over the case.

KING OF PRUSSIA, Pa. — Penn State University alumni are still grieving over the firing of longtime coach Joe Paterno, even though the university's president says the school's crisis can be blamed on former football assistant coach Jerry Sandusky.

At the second of three town hall meetings with alumni Thursday night, sometimes heated exchanges took place between the 650 alumni and university president Rodney Erickson. The final alumni session will be held Friday in New York.

Erickson says, "We're not going to let what one individual did destroy the reputation of this university." But some alumni called for the university's board of trustees to resign over their treatment of Paterno.

"I'm a big Joe Pa fan, and I think he was treated unjustly," says John Lagana of the Class of '62.
