BELLEFONTE, Pennsylvania (CNN) — The jury considering the fate of Jerry Sandusky on Friday pored over transcripts of testimony in the high-profile child rape case as the second day of deliberations got under way.

The statements of prosecution witness Mike McQueary, who testified that he saw Sandusky apparently sodomizing a boy, and defense witness Dr. Jonathan Dranov, who said McQueary’s initial account differs from what he said on the stand, were read back to jurors.

Dranov, an acquaintance of McQueary, told jurors that McQueary, a former graduate assistant and assistant coach at Penn State, told him that he heard “sexual sounds” and saw the boy in the shower when an arm reached around him, but did not actually see a sexual encounter.

Soon after, Sandusky, the team’s longtime defensive coordinator, emerged from the shower area, he said.

McQueary testified that he saw Sandusky pressing against the boy in the university shower and that it seemed obvious he was raping him.

Jurors deliberated until about 9:30 p.m. Thursday before breaking off, and began reviewing testimony from the two witnesses when they resumed their duties Friday morning.

Sandusky, 68, is charged with dozens of counts of child sexual abuse involving 10 alleged victims over a 15-year period.

As the case went to the jury, new revelations came to light.

Matt Sandusky, one of six adopted children of Jerry Sandusky, said through his attorney Thursday that he was sexually abused by the former coach, and added that he had been prepared to testify against him.

The new accusation could lead to additional charges, including incest, even though Matt Sandusky was adopted, according to Marci Hamilton, a professor at Yeshiva University’s Cardozo Law School who has represented victims and written on sexual abuse cases.

“At Matt’s request, we immediately arranged a meeting between him and the prosecutors and investigators,” attorneys Andrew Shubin and Justine Andronici said in a statement. “This has been an extremely painful experience for Matt, and he has asked us to convey his request that the media respect his privacy.”

The jurors will decide Jerry Sandusky’s fate without having heard from him on the witness stand.

During closing arguments, his defense sought to poke holes in the prosecution’s case, reminding jurors of the lack of physical evidence. Defense attorney Joe Amendola accused the alleged victims of conspiring for financial gain while blaming the media for what he described as biased coverage.

During the arguments, Sandusky’s wife, Dottie, quietly wept.

Lead prosecutor Joseph McGettigan rebuffed the defense’s account of a coordinated action among Sandusky’s accusers allegedly bent on financial windfall.

“The commonwealth has overwhelming evidence against Mr. Sandusky,” he said.

Judge John Cleland on Thursday dropped three more of the counts against Sandusky, cutting the total number of charges to 48.

He told jurors that the three counts all pertained to “alleged victim 4,” while the defense further petitioned to have all counts related to “alleged victim 8” dismissed as well.

Cleland said one count of involuntary deviate sexual intercourse duplicated another charge. Two other counts — one of involuntary deviate sexual intercourse and another of aggravated indecent assault — were not supported by testimony and the evidence presented, Cleland found.

Prosecutors dropped one of the original 52 counts earlier this week because the statute on which that charge was based wasn’t in effect on the date of the alleged incident.

Dr. Elliot Atkins testified that he diagnosed Sandusky with histrionic personality disorder, part of a class of conditions called dramatic personality disorders that are marked by unstable emotions and distorted self-images. But a second psychologist, prosecution witness Dr. John O’Brien, disputed those findings, saying that the “personality profile Mr. Sandusky exhibited was within normal limits.”

During the trial, Matt Sandusky’s name came up in the testimony of one of Sandusky’s accusers, who talked about what occurred after he played racquetball once with Jerry and Matt Sandusky.

“Matt went into the shower, and then me and Jerry came in. … He started pumping his hand full of soap, like he was going to throw it. Matt got out. … He went to another shower” area.

According to some of the accusers, Jerry Sandusky would often use shower “soap fights” as a prelude to inappropriate sexual contact.

In his 2001 autobiography, “Touched,” Jerry Sandusky wrote about his relationship with Matt Sandusky, whom he met through Second Mile when the youth was 7 or 8.

Sandusky detailed the youth’s discipline problems and struggles before he ultimately became close to his new family.

Meanwhile, a man who claims he was repeatedly sexually abused by Sandusky while a child spoke out Thursday.

“He (once) told me if I ever said anything, that nobody was going to believe me and he would get my dad fired from Penn State,” Travis Weaver, 30, said on NBC’s “Rock Center with Brian Williams.”

Weaver did not testify in Sandusky’s trial, but has filed a civil action against the former coach.
