A grand jury presentment says Sandusky, a retired defensive coach for Pennsylvania State University, performed oral sex on the teen more than 20 times in 2007 and 2008.
The grand jury report identified him only as Victim 1, but residents and his neighbors in Lock Haven quickly figured out who he was, as did members of the media. (The boy's mother declined comment when approached near her home Tuesday by The Inquirer.)
The teen was forced to transfer to a new school, Boni said, but "is doing fine now."
The Sandusky investigation began when the boy's mother told Central Mountain High School officials in 2008 that Sandusky, then a volunteer assistant football coach at the school, had sexually abused her son. School officials alerted local law enforcement, who began a wider probe.
Ultimately, prosecutors charged the retired coach with molesting at least seven other boys since the mid-1990s. They say he met his victims through the Second Mile, the foundation Sandusky started for underprivileged children.
Two former Penn State administrators, athletic director Timothy Curley and former senior vice president Gary Schultz, face trial, charged with covering up an alleged attack on a boy by Sandusky in 2002, then lying to the grand jury about it. On Tuesday, their preliminary hearing was rescheduled for Dec. 16.
Sandusky has denied any wrongdoing. His attorney, Joseph Amendola, has said some of the victims might recant or dispute the claims.
Hearing and reading about Sandusky's denial has been "emotionally devastating" for the Lock Haven teen and his mother, Boni said.
"Both are very warm, nice, earnest people."
The two lawyers have dispatched an investigator to help gather possible evidence for their civil case, he said, but pledged not to interfere with the ongoing criminal matter. He also said they were preparing the teen to be a possible witness at Sandusky's Dec. 13 preliminary hearing.
