STATE COLLEGE, Pa. (June 30, 2012)—CNN reports that it has seen e-mails that show that Penn State university’s former president Graham Spanier agreed not to take allegations of sex abuse against ex-assistant football coach Jerry Sandusky to authorities but worried they'd be "vulnerable" for failing to report the allegations.

CNN says the e-mails followed a graduate assistant's 2001 report of seeing Sandusky sexually assaulting a boy in a shower.

Spanier hasn't been charged and his attorney didn't immediately return a call Saturday.

The e-mails, first reported by NBC, show that Athletic Director Tim Curley and retired vice president Gary Schultz intended to report the allegation, but then reconsidered.

Spanier responded he was "supportive" but worried that they might "become vulnerable for not having reported it."

Schultz and Curley are awaiting trial on charges they lied to the grand jury.

Sandusky has been convicted of sexually abusing 10 boys and likely will spend the rest of his life in prison.
