(CBS/AP) BELLEFONTE, Pa. - John McQueary, whose son testified Tuesday that he saw Jerry Sandusky engaged in a sex act with a young boy in a Penn State locker room shower, as well as a young man known as "Victim 10" testified in the trial of the former assistant football coach Wednesday morning.
John McQueary told the court that his son "could not wait" and had to tell PSU administration what he saw immediately. McQueary also testified that his son was "very upset and distraught" when he called him to say what he'd seen. McQueary said he told his son to come over and discuss the alleged incident in person.
"We determined that it was imperative that he report this to the authorities at Penn State," testified John McQueary.
McQueary also testified that when he spoke with Gary Schultz, the former PSU vice president for business and finance about the incident, Schultz admitted he had "heard noise about this before."
According to PennLive.com, John McQueary's testimony was cut short after he told the prosecutor he did not recall testifying at a preliminary hearing for two Penn State officials who are charged with perjury and failure to report.
The prosecution then called the man known as "Victim 10." The witness, now 25, testified that he met Sandusky through his charity "The Second Mile." He said he had last seen his own father when he was four-years-old and was living in foster care at the time.
"We were wrestling and the defendant pinned me to the ground, pulled my shorts down and started performing oral sex on me," testified the man about an incident in the basement of the Sandusky home.
"I freaked out. I got nervous. I got scared," he went on. "He told me that if I told nobody that I would never see my family again." Later, the man testified, Sandusky apologized: "He [said he] didn't mean it, and he loved me."
He testified that on another occasion, he was riding in a silver convertible with Sandusky and, "He told me that he wanted me to perform oral sex on him and I told him no. He got displeased with what I told him. He made a threat to me." Again, the witness testified, Sandusky later apologized, said he "didn't mean to say it, and he loved me."
The man said Sandusky assaulted him on other occasions in 1998 and 1999, including another time in the same basement that involved mutual oral sex and once in a swimming pool.
Victim 10's foster mother was the third witness to testify. She told the court she "felt sick" when she learned what her foster son had allegedly endured.
Under cross-examination, the man testified that he was the roommate of another Sandusky accuser at a camp sponsored by The Second Mile.
The alleged victim also acknowledged having spent nearly two years in state prison for a robbery and involvement with drugs and alcohol but said he was doing better now.
"I'm married. I'm expecting a child," he said.
Sandusky is on trial on 52 criminal counts related to the alleged assaults of 10 boys during a 15-year period. Authorities allege Sandusky abused boys at his home and inside the football team's on-campus facilities among other places. Sandusky maintains his innocence.
