The jurors will get back to work Saturday morning. Constand stared straight ahead. "We are looking for reform, uncovering the rape culture in this country where victims are blamed and shamed".
The jurors also listened to the 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.
"Devastated, but more determined", she said.
Since starting deliberations, the jurors have re-examined both Cosby's and Constand's versions of the encounter, with particular focus on the pills he gave her beforehand.
Prosecutors immediately said they would seek a retrial. "It has been restored", said Andrew Wyatt, his spokesman.
And while Montgomery County District Attorney Kevin Steele vowed to retry the famous comedian, Hollywood is up in arms over what some called a flawed justice system.
"As a very special friend once stated, 'Truth can be subdued, but not destroyed, '" she said. "In other words, it's too early to celebrate Mr. Cosby". The jury may be looking at Constand and wondering how she remembers what happened the night she claims she was drugged and assaulted, or even why she voluntarily took pills. "I also felt his hand inside my vagina moving in and out, and I felt him take my hand and place it on his penis and move it back and forth".
Bill Cosby's defense lawyer says he is concerned about the entertainer's health following what he described as an "unfair" aggravated indecent assault trial that ended in a mistrial Saturday.
The jury was made up of four white women, six white men, one black woman and one black man; Cosby is black. Are you surprised by this deadlock today?
In the deposition, released in 2015 at the request of The Associated Press, Cosby said he obtained several prescriptions for quaaludes in the 1970s and offered the now-banned sedatives to women he wanted to have sex with.
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.
He did not testify in his own defense, and so avoided a grilling about those admissions.
Count 1 alleges that Cosby didn't have consent when he penetrated Constand's genitals with his fingers.
Before going on trial, Cosby expressed hope he could eventually resume his career.
The judge, meanwhile, assured the panel members - whose identities remain sealed by court order - that he appreciated their efforts throughout the two-week trial.
Before the trial, Cosby told CNN's Michael Smerconish that he wants to return to comedy and activism.
David Harris, a professor at the University of Pittsburgh School of Law who specialises in criminal justice, said the hung jury did not mean that a civil jury would clear Cosby of liability.
"They've been intimate", he said in his closing statement.
"There was no pause or hesitation about that, and we're moving forward", he told reporters. But that is no crime, he said.
It was the only criminal case to arise from allegations from more than 60 women that cast Cosby as a serial predator who gave drugs to women before violating them.
