Bill Cosby gestures as he leaves the Montgomery County Courthouse during his sexual assault trial, Friday, June 16, 2017, in Norristown, Pa.
The 79-year-old Cosby is accused of drugging and molesting a Temple University employee in 2004 at his home near Philadelphia. The judge instructed them to keep working, but despite marathon 12-hour sessions, the jury said on Saturday it was at an impasse. "He walked out but the bars were all around him", she said.
"Our plan is to move this case forward as soon as possible", he said.
About 60 women have accused Cosby of sexually assaulting them, effectively ending the long career of the entertainer once known as "America's dad" for his role in the 1980s television hit "The Cosby Show".
Jurors also asked for, and received, a definition of reasonable doubt, the threshold that prosecutors must cross to win a conviction, and reviewed testimony from Constand and her mother about phone conversations they had with Cosby after the encounter. "She spent a lot more time trying to forget what happened than trying to remember that night".
Much has been said and written about the sex scandal that has torpedoed Bill Cosby's legacy - so much so that it can be hard to recall how he reached the point of facing trial on three counts of felony aggravated indecent assault.
Cosby's team immediately went on the attack. She described the prosecutor as "heinously and exploitively ambitious". She accuses Cosby and his team of lawyers and representatives of defaming her and calling her a liar for speaking out about the accusations. How do I describe the judge? Given the manner in which she was dismissed by the previous district attorney, she had no option but to file a civil suit.
Cosby lawyer Brian McMonagle fired back that jurors might be under the assumption they have to deliberate until "the cows come home". "It has been restored".
As news reporters streamed out of the room, several other Cosby accusers, some in tears, waited in line to hug Constand, who smiled broadly and maintained her composure. He also found success with his "Fat Albert" animated TV show and starred in commercials for Jell-O pudding.
About a dozen excerpts from Cosby's deposition testimony in which he talks about obtaining quaaludes to give to women he wanted to have sex with. She said that the star brought her three blue pills, telling her they would help her relax and they were safe.
Prosecutors argued Cosby drugged and sexually assaulted Constand. On Saturday, they came back and told O'Neill they were hopelessly deadlocked.
"I have been nothing but extraordinarily impressed by you all", O'Neill told the jury, adding that declaring a mistrial meant neither a victory nor a loss.
Nearly immediately, the prosecution announced its intention to retry the comedian and former Temple trustee.
"I know the side that I'm on and the side that I'm hoping for, and after that, there's more work to be done", he said.
Throughout the trial, 13 witnesses protested at Montgomery County Courthouse, just outside Philadelphia. Neither the judge nor attorneys said they were aware of how the jury split on Cosby's guilt or innocence.
Prosecutors in Bill Cosby's sexual assault case are praising the accuser and say she's "entitled to a verdict in this case". The judge then declared a mistrial. Cosby was charged shortly before the statute of limitations was set to expire.
