The testimony came on what was a truncated day in a trial that has moved at a brisk pace since testimony began last week. Judge John Cleland told jurors that the defence could rest its case by Wednesday, which would mean closing arguments could come Thursday morning.
"This is all very tentative, you understand," he told the 12 jurors and four alternates, adding that since they will be sequestered in a hotel while they deliberate they should "pack appropriately."

It was still unclear how Sandusky's defence team, led by attorney Joe Amendola, would proceed on Tuesday. After the proceedings ended for the day, when asked if he would testify on his own behalf, Sandusky looked an Associated Press reporter in the eye and said nothing.
Cleland told jurors of the possible timeline after three defence witnesses testified that Sandusky was an admired local figure because of his ties to Penn State and the outreach of The Second Mile, the charity for at-risk youth that the defendant founded in 1977.
Former Penn State assistant coach Dick Anderson, who worked with Sandusky for several years, testified that he and other members of the football staff were present when Sandusky brought young boys into the team's showers.
He said he never witnessed anything inappropriate.
"If Jerry would bring someone in with The Second Mile, they had been working out, for whatever reason they came in, it was not uncommon ... with the other coaches in the shower as well," Anderson said.
Anderson, who coached at Penn State from 1970 to 1983 and again from 1990 to 2011, said adults and children often shower together at gyms. He noted, for example, that it's not unusual for him to be in the showers with boys at the YMCA.
Anderson took the stand after prosecutors presented their 21st, and final, witness, a woman whose son said Sandusky raped him in the basement of the coach's home.
The woman said her son, labeled Victim 9 in court records, told her that Sandusky called him late one night after the first round of charges were filed in November, asking if he'd be a character witness. But the next month, prosecutors brought charges against Sandusky, alleging he'd had forced anal sex with the boy.
The woman said her son's laundry would often be short of underwear and he would claim he had thrown it away because he had an accident. Last week, the teen said Sandusky forced him to have anal sex that made him bleed.
"I always wondered why he never had any underwear in the laundry," she said. "There was never any underwear, any socks ... that was odd to me."
Also Monday, prosecutors withdrew one count against Sandusky, saying the statute he was charged under did not apply at the time of the alleged illegal contact.
That leaves 51 counts involving 10 alleged victims over a 15-year span. Sandusky, whose November arrest led to the ouster of Penn State's president and the firing of Hall of Fame football coach Joe Paterno, has denied wrongdoing.
During his testimony, Anderson said Sandusky had a "wonderful reputation" in the community.
"He was well thought of in every regard," Anderson said.
He also testified about the busy schedule Penn State coaches kept.
Another former Penn State coach, Booker Brooks, took the stand to vouch for Sandusky's character, as did a State College area political consultant, Brent Pasquinelli, who raised money for The Second Mile. Brooks said Sandusky's reputation was "exemplary, top-notch," while Pasquinelli called Sandusky "a local hero."
Besides Anderson, Brooks and Pasquinelli, three other witnesses testified for the defence Monday: a woman who ran a golf-related charity that one accuser was recommended for by Sandusky, a young man who knew Sandusky through The Second Mile and vouched for his reputation, and a schoolteacher who said Sandusky seemed genuinely interested in helping one of the alleged victims in the case. Each was on the stand for no more than 10 minutes.
A number of potential witnesses could still testify. Along with Sandusky himself, they include his wife, Dottie; an expert who could discuss whether Sandusky has "histrionic personality disorder," as his lawyers have said in court papers; and a physician who spoke with key prosecution witness Mike McQueary the day he allegedly saw Sandusky attack a child in the shower in 2001.
The defence list of potential witnesses also included members of Paterno's family, but it was unclear how they might fit into the defence case or whether they will be called.
Tom Kline, a Philadelphia lawyer who represents one of the accusers, said he was served a defence subpoena on Monday, ordering him to produce a copy of the fee agreement he has made with Victim 5, along with copies of his interactions with reporters.
Lawyers involved in the criminal case are barred from speaking in detail about the case under a gag order imposed by Cleland.
In their questions to prosecution witnesses, the defence has sought to show how the stories of accusers have changed over time, that they were prodded and coached by investigators and prosecutors, that some are motivated to lie by the hopes of a civil lawsuit jackpot, and to paint Sandusky's interactions with children as misunderstood and part of a lifelong effort to help, not victimize, them.
Amendola pressed the accusers for dates and locations, details of their involvement with the kids' charity Sandusky founded, arrests or drug problems, contacts they had with Sandusky in the years since the alleged abuse ended and the terms of representation deals with civil lawyers. At least six said they told incorrect or incomplete stories in early contacts with police, and three testified that some of the details only came back to them in recent years.
