The actor's statement was recorded more than a decade ago, as part of a civil suit Constand had filed against him and settled in 2006. "Mr. Cosby admitted to giving these quaaludes to women, young women, in order to have sex with them", Snyder said.
Harrison Snyder, 22, who is the youngest juror in the high-profile case, explained why the jury chose to convict the comedian on three counts of aggravated indecent assault.
Snyder added that while it "wasn't an open and shut case", he had no doubt the jury made the right decision. "He was a free man, but I remember when we met him at Robben Island where he had been in a prison for all of those years", said Cosby.
Snyder also brushed off suggestions the verdict is a reflection of the impact of the #MeToo movement against sexual misconduct, which only hit headlines in October (17), months after the judge declared a mistrial in prosecutors' first attempt at holding Cosby accountable for the 2004 incident.
In the testimony, which was read to jurors at both trials, he described giving quaaludes to women before sex in the 1970s and his encounters with Constand, a Temple University women's basketball administrator.
"I don't think it really necessarily mattered that these five other women were here because he said it himself - that he used drugs for other women", Snyder told "GMA".
Snyder said he believed Constand's testimony, but feels he would've convicted Cosby even if the additional five women hadn't testified, which Judge Steven O'Neill allowed at the second trial. They said race and the #MeToo movement were never discussed.More news: Strong reactions after comedian delivers scathing 'roast' of White House press secretary
"After thoughtful and meticulous consideration of the information and evidence provided to us, we came to our unanimous verdict".
Interestingly enough, the jurors also released an official statement and said the recent #MeToo movement was not an influencing factor as it wasn't discussed at all during the deliberation.
Prosecutors said they are confident Cosby's conviction will stand.
Cosby is facing a maximum sentence of 30 years in prison; ten years for each conviction. He frequently referenced living in prison as "that place", explaining to the publication how he plans to survive his incarceration.

"I only found about it after I got home and looked online to see what everything was", he shared.
He cited the testimony of prosecutors' first witness - Dr Barbara Ziv, an expert in sexual assault victim behaviour - as key to explaining away numerous attacks the defense lobbed at Constand for inconsistencies in the story she told police.
