Defense attorney Karl Rominger declined to say why his client did not take the stand, citing the gag order imposed by the court.
"We can't talk," he said.
Sandusky sat quietly as the defense ended its case and attorneys gathered up books and folders. He has shown virtually no emotion during the trial.
In interviews, attorneys for two of the victims were incredulous that Sandusky did not testify, particularly after he granted interviews to two national news organizations.
"While an accused has the right not to testify, it cannot possibly escape the jury's attention that the same man who gave an interview to a national television audience would not come into the courtroom and look them in the eyes and face cross-examination," said Thomas Kline, who represents Victim 5. "Mr. Sandusky gave up the opportunity to confront all of the charges, which were left almost unrefuted at the close of the evidence."
Slade McLaughlin, who represents Victim 1, wondered what Sandusky was thinking.
"What does he have to lose at this point? It's fourth and long, and he's way down on the scoreboard," McLaughlin said.
Earlier in the day, the defense made some of its only headway. A family friend of prosecution witness Mike McQueary contradicted the former Penn State assistant football coach, saying McQueary never expressly said he saw Sandusky sodomizing a boy in the locker-room showers.
"Each time I would ask, 'What did you see, what did you see?' testified John Dranov of Boalsburg. "And he kept coming back to the sounds."
Both men, McQueary last week and Dranov on Wednesday, testified that McQueary's father, John, had called Dranov to his house late on a Friday in 2001, after the younger McQueary reported having stumbled onto a traumatic scene.
Mike McQueary swore on the stand that he specifically told his father and the doctor that he had witnessed something sexual, disturbing, and wrong when he arrived in the locker room.
Dranov said McQueary never specifically said he had witnessed a sex act. The younger man, though terribly upset, his voice shaking and hands trembling, said he had heard "sexual sounds," Dranov said.
Dranov said he asked, "Mike, what do you mean?"
"Sexual sounds, you know what they are," McQueary responded.
"No, I don't," Dranov said he answered.
McQueary, the doctor testified, related that he had looked into the showers and seen a boy. A moment later "an arm reached out and pulled the boy back."
A man stepped out of the shower - it was Sandusky, the physician testified.
The testimony cuts in two ways: One, whether McQueary actually saw a sex act, and whether he accurately reported it to others, including revered Penn State coach Joe Paterno. Two, whether the jury can believe McQueary's testimony.
Defense lawyer Rominger asked the doctor: "Did he describe seeing any particular sex act?"
"No," Dranov answered, "he did not. Did he give me any graphic description? He did not."
Still, he said, "it was clear in Mike's mind, this was an incident that should be reported."
Sandusky, accused of molesting 10 boys over 15 years, on Wednesday got support from two former youths in the Sandusky charity the Second Mile who said that they knew him well - and that he never touched them inappropriately.
David Hilton, 21, testified that he grew tired of repeated police interviews and questions about the allegations. He got the impression that the investigators wanted to hear certain answers, warning that he could be prosecuted for not telling the truth, he said.
"They wanted me to say something," Hilton said, "that wasn't true."
