Cosby faces up to 10 years in prison for each count.
But in the end, it was the years-old account of one of Cosby's very first accusers that now threatens to send him to prison, potentially for the rest of his life.
Like many of Cosby's other accusers, Constand said she was drugged and violated while unable to defend herself.
Cosby then left the courthouse with his lawyers and publicist. "We are so happy that finally we can say women are believed".
"I feel like my faith in humanity is restored", Bernard said.
As the verdict was read, Cosby looked down with a sad expression. "We don't think Mr. Cosby's guilty of anything and the fight is not over", he said.
"Yes, you did hear about a con", Feden said, her voice rising as she moved toward Cosby and pointed at him.
The alternate jurors are being kept away from the main panel of seven men and five women deliberating Cosby's fate. He is not allowed to leave the state of Pennsylvania.

Ethics and legal experts point out that the legal threshold prosecutors must reach in order to convict a public official of bribery is high.
The case is the first celebrity sexual assault trial since the #MeToo movement began last fall, and as such, it represents a test of how the cultural movement will translate into a courtroom arena.
After the verdict was handed down, District Attorney Kevin Steele asked the judge to revoke bail, prompting an angry outcry from Cosby. "It was the right thing to do". Cosby's lawyers slammed #MeToo, calling Cosby its victim and likening it to a witch hunt or a lynching. Cosby claimed the encounter was consensual.
Cosby didn't take the stand in his retrial, just as he hadn't in his first trial.
Cosby gave the deposition more than a decade ago as part of Constand's civil suit against him, which he settled in 2006 for almost $3.4 million.
Cosby was convicted Thursday of drugging and molesting a woman 14 years ago.
His retrial began April 9. It was the only criminal case to arise from a barrage of allegations from more than 60 women who said the former TV star drugged and molested them over a span of five decades.
Constand testified she went to Cosby's house to discuss a potential career change when he gave her three blue pills he said would relax her. Jackson's testimony bolstered Cosby's efforts to show Constand made up the allegations against him to extort a big civil settlement. The defense team continued its line of attack on Cosby's accusers, saying they fabricated their stories for money and fame.
Constand faced withering questions from Mesereau on cross-examination, as part of a multipronged defense focused on shaking her credibility and that of the other witnesses. His portrayal of the sweater-loving Cliff Huxtable on "The Cosby Show" was one of the first mainstream TV shows to feature a black upper-middle class family.
