As they pored over Cosby's words, the jurors appeared to struggle with some language in one of the charges against him: "without her knowledge". It was read to them by the judge.
On Monday, the defense moved through its case - quickly, reports Laura Benshoff of member station WHYY. Lawyer Gloria Allred represented a second accuser who told jurors that she too had been drugged and sexually assaulted by Cosby.
The jury asked to hear the context of Cosby's deposition testimony about the pills, and then resumed deliberations. McMonagle asked. "This is why this case got thrown in the trash can". They've been deliberating for two hours, and have had dinner brought in. She says they left her semi-conscious.
Schaffer also said that local police officers believe that Cosby suffers from vision impairment, adding credence to the comedian's claims that he is blind.
"I would suggest to you that Andrea Constand is a real victim", he said.
But they didn't come up with a verdict, leaving them exhausted and spent after a long day in the jury room. Constand did make a brief call to Cosby at 9:45 p.m. March 16, 2004, he said. He could face up to 10 years in prison for each charge.
Roughly 60 women have come forward to accuse Bill Cosby of sexually assaulting and/or drugging them in the last several years. Constand said on the witness stand she did not know Jackson. He says the encounter was consensual. According to Constand, she was suffering the effects of a significant trauma when she first reported the sexual assault to law enforcement.
Some of these women, including Constand, have received cash payouts from Cosby in civil trials, but for numerous allegations the statute of limitations for criminal prosecution had lapsed.
Defense lawyer Brian McMonagle said Cosby and Ms Constand were lovers who had enjoyed secret "romantic interludes", insisting the 2004 encounter was consensual.
Steele also reminded jurors about a telephone conversation in which Cosby apologized to Constand's mother and described himself as a "sick man". Cosby did not take the stand. Constand took a seat in the front row on the opposite side of the courtroom.
Prosecutors are poised to give their closing argument Monday afternoon.
The Associated Press does not typically identify people who say they are victims of sexual assault unless they grant permission, which Constand has done.
For the prosecution's closing statement, Steele argued that Cosby's own statements showed his guilt.
" 'We're not flawless, are we?' he said, pausing and looking at Camille Cosby, 73".
Count 1 alleges that Cosby didn't have consent when he penetrated Constand's genitals with his fingers. He just testified for six minutes and the lawyers immediately started their closing arguments. Cosby, as expected, waived his right to testify.
In a sworn statement without the jury present, Cosby told Judge Steven O'Neill that he did not plan to testify in his own defense.
Prosecutors called 12 witnesses over a week of testimony, and Constand was chief among them.
A veteran of the Philadelphia legal scene, he made his name in the district attorney's office prosecuting high-profile murder cases before moving into private practice in the early 1990s.
At the time, Constand was the director of team operations for the Temple University women's basketball team.
Cosby's wife of 53 years, Camille, was in the courtroom for the first time in the trial.
Monday's closing arguments finished out Day 6 of Cosby's criminal trial. The couple also has four daughters.
The defence opens it case Monday. Cosby raised his hand when the judge said he couldn't see the entertainer.
He showed jurors copies of deposition transcripts and police interviews in which Cosby admitted to giving Constand a dose of Benadryl, an over-the-counter allergy medication he uses as a sleep aid, and discussing his sexual preferences. Minutes later, his testimony filed, the 79-year-old Cosby's lawyers drew their defence to a close.
