With the jury struggling to find common ground, some of the other women who have accused Cosby of sexual assault confronted sign-waving Cosby supporters gathered on the courthouse steps to await the outcome.
The jury of seven men and five women has been sequestered in a local hotel not far from the Montgomery County Courthouse in Norristown, Pennsylvania.
The trial began on June 5, and the jury began deliberating Monday evening. That prompted O'Neill to ask the comedian on Friday whether he understood that a hung jury would allow prosecutors to retry him. Lawyer Brian McMonagle also anxious that some jurors might compromise "their views and their values" for the sake of reaching a unanimous decision. The jury is set to return for the fifth day of deliberations on Friday at 9 a.m. They attacked the judge, in a letter from Cosby's wife Camille, as "arrogant" and Steele as "heinous" and "ambitious". He hasn't testified at the trial yet.
Judge O'Neill sent the jurors back to continue deliberating. He said he'd let the jurors work as long as they wanted.
Jurors also asked to hear Cosby's police statement and the 2005 civil deposition that, when unsealed by a federal judge, became the impetus for the case against the entertainer to be re-opened in 2015. He told them they had to rely on their collective memory. Some of them looked defeated as the judge sent them back to the jury room.
Prosecutors, meanwhile, used her testimony as well as the words of a second accuser, Kelly Johnson, to portray Cosby as a serial predator. "It doesn't surprise me that this jury is split". I also want to thank the supporters who have been here.
The case has helped demolish Cosby's nice-guy image, cultivated during his eight-year run as Dr. Cliff Huxtable on the top-rated "The Cosby Show" in the 1980s and '90s.
If convicted, Cosby could be sentenced to up to 10 years in prison for each count of aggravated indecent assault he faces. Quaaludes was a highly popular party drug in the 1970s that was banned in the U.S.in 1982.
Constand is a former college basketball star and managed the women's basketball team at Temple University.
In a 2005 deposition, Cosby described giving Constand pills before engaging in sexual contact with her.
Cosby later told police the pills were Benadryl, an over-the-counter cold, and allergy medicine.
Cosby's defense attorneys argued the sexual contact was consensual and worked to highlight inconsistencies in Constand's testimony on cross-examination. One batch of requested testimony hadn't even been transcribed yet.
The 12-member jury informed the court that after almost 30 hours of deliberations, they had been unable to reach a unanimous decision.
"This is an incredible organize that has just acted with incredible dignity and fidelity", O'Neill said. Following the failure to reach a unanimous decision, the judge encouraged the 12 jury members to come to a consensus. The prosecution would then have four months to decide on whether to seek a fresh trial with a new jury.
He did not take the stand in his sexual assault trial.
