A man known as Victim 6, whose allegations against convicted child molester Jerry Sandusky first launched an investigation in 1998 that resulted in no charges, has sued Sandusky, his charity and Penn State in federal court.

A six-count complaint filed Tuesday in the U.S. District Court for the Eastern District of Pennsylvania alleges Penn State and The Second Mile, Sandusky’s now-embattled charity for struggling youths, concealed Sandusky’s inappropriate pattern of behavior with young boys and failed to provide reasonable supervision for the plaintiff, identified in the filing as John Doe 6.
