(CBS/AP) BELLEFONTE, Pa. - The young man known as "Victim 1" testified Tuesday that a school guidance counselor initially didn't believe his claims of abuse by Jerry Sandusky. The witness claimed his counselor said the former Penn State assistant football coach had a "a heart of gold."
But a social worker who met with the young man testified that she had enough information after her second meeting with the teen to determine he had abused the boy.
Clinton County Children & Youth Services caseworker Jessica Dershem testified Tuesday that the teen was initially uncomfortable talking to her. But she says he soon began to give her detailed accounts of sexual encounters involving Sandusky.
Dershem says she also met with Sandusky. She says he denied having sexual contact with the boy but did acknowledge lying on top of him and blowing "raspberries" on the boy's stomach.
The teen, now 18, tearfully recounted repeated instances of Sandusky kissing him, fondling him and performing oral sex, mostly in the basement of Sandusky's State College home during sleepovers while Sandusky's wife was upstairs. He also testified that he went to church with the Sandusky's - dressed in clothes Sandusky had bought him - on a morning after Sandusky had performed oral sex on him.
He said he stayed quiet about the abuse, in part because his mother thought Sandusky was a positive influence in his life. But eventually he asked his mother if there was a website used to track sex offenders.
"I wanted to see if Jerry was on there," he testified.
That ultimately led to a meeting with a guidance counselor where he said he'd been abused. At first, the counselor didn't believe him and questioned the wisdom of going to authorities, the witness said.
"They said we needed to think about it and he has a heart of gold and he wouldn't do something like that. So they didn't believe me," he said.
On cross-examination, Sandusky's attorney, Joe Amendola, pressed the accuser about his initial statements to a counselor and later the grand jury that were less detailed than later testimony.
The teen, who graduated from high school last week, responded that it was an embarrassing subject to talk about.
"I don't believe anybody would want to talk about it," he said.
Sandusky didn't visibly react to the teen's account and looked straight ahead during his testimony.
