The sequestered panel deliberated for about four hours late Monday before asking to go back to the hotel.
They'll resume deliberations Tuesday morning. Instead, his defense consisted of a roughly six-minute appearance by Cheltenham Township Police Department Sergeant Richard Schaffer, who led the 2005 investigation into allegations Cosby drugged and sexually assaulted Constand at the comic's suburban Philadelphia home in 2004. It was read to them by the judge.
The jury of seven men and five women was expected to get the case later in the day.
Johnson, who worked at the William Morris talent agency, said that in 1996, Cosby gave her a pill that incapacitated her and then he sexually assaulted her. McMonagle said that while the comedian had been unfaithful to his wife, he didn't commit a crime. He has said the sexual encounter with Constand was consensual.
"Drugging somebody and putting them in a position where you can do what you want with them is not romantic".
During his closing argument, McMonagle flipped between stage-whispered intimacy and earsplitting verbal explosions - as he ran through a long list of possible culprits he says are responsible for landing his client at the center of one of the most high-profile criminal cases in recent American history.
The Cosby defense presentation was startlingly fast: one witness, a police detective, who was on the stand for a total of six minutes.
Cosby, 79, could serve 10 years in prison for the charges of three counts of aggravated indecent assault, making it possible the comedian and alumnus could be in prison for the rest of his life.
Prosecutors will give their closing argument Monday afternoon.
Cosby attorney Brian McMonagle argued that the behavior of Cosby's accuser in the aftermath of her alleged sexual assault raised too many questions for a jury to believe her claim that Cosby assaulted her.
Constand, a 44-year-old former employee of the women's basketball program at Temple, testified last week that Cosby gave her three blue pills and then penetrated her with her fingers against her will as she lay paralyzed and half-conscious.
"This isn't talking to a trustee".
"You know why we're here", McMonagle said scornfully, nodding toward two Cosby accusers in the audience - Victoria Valentino and Linda Kirkpatrick - who did not testify in the case.
In the closing, McMonagle also sought to dismiss Cosby's attempts to pay Constand's tutition not as an attempt to buy her silence for a criminal act but a way to avoid a confrontation with his longtime wife, Camille.
Cosby was painted as a predator and callous manipulator by the prosecution, while the defence portrayed him as a lover and kindly mentor.
She sat in the front row, across the aisle from Constand, who didn't react to McMonagle's two-hour closing but smiled at the end of it. She denied they had a romantic relationship and said she had rebuffed previous advances from him. O'Neill asked Cosby if he discussed the issue with his attorneys and if he understood there is no obligation to testify, as the burden to prove the charges of aggravated indecent sexual assault case lies exclusively with the prosecutors.
"Cosby testified over a decade ago as part of her lawsuit, eventually settling the case for an undisclosed sum". His deposition was sealed for years until a judge released parts in 2015 at the request of The Associated Press, prompting a new set of prosecutors to take a fresh look at the case and charge him.
In his excited and animated closing, McMonagle made emotional appeals to the jury, weaving anecdotes about parenting and patriotism as he argued Cosby's prosecution was "nonsense" driven by lawyers and media attention.
Constand received an unknown amount of money from a civil case she filed.
Steele also reminded jurors about a telephone conversation in which Cosby apologized to Constand's mother and described himself as a "sick man".
"This is where all the fancy lawyering can't get you around your own words", he said.
And all along, they said Constand was a willing romantic partner.
"She said one thing yesterday, another thing today".
It's the first day a family member has accompanied him to court.
Cosby acknowledged that he obtained Quaaludes, a prescription sedative, in the 1970s to give to young women.
Cosby later told police the pills were Benadryl, an over-the-counter cold and allergy medicine. Prosecutors have suggested he drugged her with something stronger - perhaps quaaludes.
Earlier, Judge O'Neill announced in court the defense would call only one witness, Schaffer.
Steele also noted that Cosby, when asked by police, said he never knew Constand to be dishonest.
