One of the last witnesses called was Dr. Jonathan Dranov, a physician summoned to the home of Mike McQueary's father in February 2001 to hear McQueary's account of seeing Sandusky sexually assaulting a boy in the campus showers. The boy, known only as Victim 2, has never been identified and isn't known to prosecutors.
Dranov testified that McQueary told of hearing "sexual sounds" and seeing a boy in the shower before an arm reached around to pull him out of view. McQueary said he made eye contact with the boy and Sandusky later emerged from the showers, Dranov said.
That account is different from what McQueary told a grand jury and testified to at a preliminary hearing and at the trial. He has said he saw Sandusky directly behind the boy's back, moving his midsection enough to convince McQueary it was a sex act.
Dranov told the jury that McQueary described hearing sounds he considered sexual in nature but did not provide him with a graphic description of what he saw.
"It just seemed to make him upset so I backed off that," Dranov said.
Asked to describe McQueary's demeanor, Dranov said: "His voice was trembling. His hands were shaking. He was visibly shaken," Dranov said.
McQueary's report to his superiors and Penn State officials' failure to go to outside law enforcement led to the firing of Paterno, who died of cancer in January.
McQueary had testified earlier in the trial that he wasn't "over-descriptive" in his conversation with Dranov, saying he told the doctor that what he saw was sexual, wrong and perverse.
David Hilton, who met Sandusky through a summer camp of his charity, testified Wednesday he felt like investigators were trying to coach him into accusing Sandusky.
"When it got to the second or third time I felt like they wanted me to say something that isn't true," he said.
During cross examination, lead prosecutor Joe McGettigan told Hilton that Hilton's uncle had contacted authorities out of concern after hearing of the initial charges against Sandusky.
Prosecutors allege that Sandusky met his alleged victims through The Second Mile charity. Sandusky founded the organization that once was lauded for its efforts to help at-risk children.
Sandusky didn't take the stand after his lawyer suggested in opening statements that he might and a day after his wife, Dottie, testified. In interviews Sandusky did shortly after his arrest in November, with the support and presence of defense attorney Joe Amendola, his responses were halting and uncertain, raising doubts about how he might stand up to cross-examination.
Criminal defendants in Pennsylvania, in serious crimes, generally are required to waive their right to testify on their own behalf, although that does not always happen in open court.
One of the jurors was excused from the case Wednesday with an illness; the female juror was replaced by an alternate, also a woman.
Sandusky attorney Karl Rominger also asked Cleland to dismiss five counts related to so-called Victim 8, the other boy never identified by investigators. Rominger argued that the timing of the charges had not been proven by the testimony of a janitor's co-worker, who said the janitor had told him he saw Sandusky molest the boy in a shower. The Penn State janitor himself was ruled not medically competent to testify.
The judge didn't immediately rule on the motion.
