"If after further deliberations, you are still deadlocked on some or all the charges, you should report that to me", said Judge O'Neill.
The jurors did not speak with reporters, but their inability to reach a verdict, after more than 100 hours of testimony and deliberations in this suburban Philadelphia courtroom, brought home how divided opinions are about Cosby - and about a lot more. "A mistrial is merely the justice system at work". Prosecutors reopened a criminal probe and filed charges in 2015 after Cosby's deposition in the woman's 2005 lawsuit was unsealed, and they realized the 12-year statute of limitations for felony sexual assault had not yet expired.
A conviction could send Cosby to prison for the rest of his life, but the case has already helped demolish Cosby's nice-guy image, cultivated during his eight-year run as Dr. Cliff Huxtable on "The Cosby Show", the top-rated 1980s and '90s sitcom.
In a strongly-worded statement read by an aide, Bill Cosby's wife, Camille, took aim at the prosecutor, who she called "heinously and exploitatively ambitious", and the judge who she described as "overtly arrogant".
Bill Cosby stood silently as his spokespeople and attorneys spoke in the rain outside the courthouse, then waved to the crowd as he was led to a waiting SUV. "He remains on bail and accused on all counts".
On Friday, the jury asked to review multiple pieces of evidence, including Cosby's decade-old deposition testimony about quaaludes.
Some of the many women who accused Mr Cosby of drugging and assaulting them over a 40-year time span were present in court last week awaiting the verdict.
"Mr. Cosby's power is back".
Legal experts had always warned that the "he said, she said" nature of the case was going to be hard to prove in court, not least because it happened so long ago and lacked physical evidence.
Cosby plans to spend the weekend with his family, "enjoying this moment", Wyatt said.
Mattel unveils diverse line of Ken dolls
With Barbie approaching her 60th birthday, Mattel have launched a new phalanx of on-trend Ken dolls fit for the 21st century. The iconic toy became available in new sizes (tall, curvy and petite) with different skin tones and fashion ensembles.
The trial jury was not able to come to a unanimous, or even majority, decision regarding the case involving the alleged victim, Andrea Constand.
McMonagle, in his closing argument, pointed out that Constand telephoned Cosby dozens of times after the alleged assault.
Constand testified that the pills, which Cosby did not identify at the time, left her disoriented and unable to resist. He said the encounter occurred in 1990, while Johnson insists it was 1996.
Constand "has shown such courage through this, and we are in awe of what she has done", Steele said.
A few of Cosby's accusers sat behind her and some sobbed as the judge declared the case a mistrial.
Cosby was the first black actor to star in a network show, I Spy, in the 1960s and created The Cosby Show two decades later.
But it was his reputation as a public moralist who urged young people to pull up their saggy trousers and start acting responsibly that prompted a federal judge to unseal portions of an explosive deposition he gave more than a decade ago as part of Constand's civil lawsuit against him. The 79-year-old TV star said in a 2006 deposition that he got seven prescriptions for the powerful sedative in the 1970s for the goal of giving them to women before sex.
Cosby has said he gave Constand the cold and allergy medicine Benadryl before their sexual encounter at his home in 2004.
Constand was the Temple University women's basketball team manager, and Cosby was a significant donor to the school, as well as a member of the board of trustees. "Why are we running from the truth of this case - this relationship?"
After a lunch break, jurors are expected to rehear testimony from accuser Andrea Constand and her mother about phone calls with Cosby.
