BELLEFONTE, Pennsylvania (CNN) — The prosecution is expected to call more witnesses Thursday in the case against former Penn State coach Jerry Sandusky, who is accused of sexually abusing boys over a 15-year period.
“Things are moving along quicker than anticipated,” Pennsylvania judge John Cleland said before ending Wednesday’s proceedings.
The prosecution could be finished calling witnesses by Friday, he said.
Jurors on Wednesday heard graphic testimony from three alleged victims, the father of a then-graduate assistant who said he witnessed Sandusky raping a boy, and a janitor who testified that he saw two pairs of legs in a shower, believed to be the ex-coach and a child.
After he saw the legs, Ron Petrosky said another janitor, who suffers from dementia and isn’t able to testify, said he witnessed the boy performing oral sex on the former coach. Defense attorney Joe Amendola sought to make that testimony inadmissible.
The men spoke on the third day of the case against the former assistant football coach, who’s pleaded not guilty to the 52 criminal counts and has denied his interactions with the children were sexual.
Five of 10 alleged victims have so far testified, and two of those are not expected to take the stand.
Among those who testified Wednesday was a 25-year-old man identified as “Alleged Victim No. 10” who said that as a boy, Sandusky abused him on at least five occasions in the basement of Sandusky’s Pennsylvania home.
Sandusky sat expressionless during the trial that was initially expected to continue for three weeks but has since progressed more rapidly than expected.
John McQueary, the father of a then-graduate assistant who says he witnessed a rape, also took the stand Wednesday.
“I knew there was something wrong,” the elder McQueary said, describing a phone conversation with his son following the alleged incident.
“I said, ‘What’s the matter?,'” McQueary recalled. His son, Mike, then told him: ‘Coach Sandusky (was) in the shower with a young boy,'” he testified.
The former coach “was positioned behind the young man, and I believe he said up against the shower wall,” the elder McQueary said. “He said, ‘It didn’t take a rocket scientist to figure out what was going on.’ “
A day before, Mike McQueary testified that he saw what appeared to be Sandusky having anal sex with the boy.
He said he had informed university officials, though didn’t use the words “anal sex” because he “didn’t feel comfortable.”
Defense attorney Karl Rominger cross-examined the younger McQueary on Tuesday, asking him about angles of his view and the reported date of the alleged incident, which prosecutors had to adjust from 2002 to 2001.
The elder McQueary also testified Wednesday that he met with Gary Schultz, the former Penn State vice president who oversaw campus police, to follow up on what his son had told authorities.
Prosecutors said Schultz held a secret file that detailed alleged incidents pertinent to the Sandusky investigation, which was initially not made available to the grand jury investigation.
Schultz and Tim Curley, Penn State’s former athletic director, have pleaded not guilty to charges of perjury and failing to report an alleged sexual assault of a child.
The file allegedly shows inconsistencies with what Schultz and Curley told a grand jury, according to court documents filed by prosecutors.
They say e-mails from Schultz, Curley and others further contradict their testimony, though CNN cannot independently confirm that account.
The university responded Tuesday saying that it had received “several subpoenas and gathered documents from many sources across the institution.”
In opening statements, defense lawyer Amendola suggested his client would take the stand and say he routinely “got showers with kids” after working out.
Men identified as Alleged Victims No. 5 and 7 also testified Wednesday, telling jurors that they both attended college football games with Sandusky after joining his Second Mile camp.
