Though more than 60 women have accused Bill Cosby of sexual assault, it was the testimony of Andrea Constand that resulted in his conviction. Cosby was found guilty in April of drugging and raping Constand in 2004. Now, Constand is speaking out about the incident for the first time. 

In an interview for Dateline with NBC News’ Kate Snow, Constand opened up about the details of her assault. TODAY published a clip of the interview, which will air in its entirety on Friday.

At the time of the assault, Constand was working as operations manager for Temple University women’s basketball program. Cosby had been mentoring her for months, and invited her over to his home to discuss her future plans. 

"Three blue pills. And he put his hand out and I said, 'What are those?' And he said, ‘They'll help you relax,'" she recalled. "And I said, ‘Are they natural? Are they, like, a herbal remedy?' And he said, 'No, they're your friends. Just put them down.'"

Constand told Snow she took the pills because she trusted Cosby. "I trusted that they would maybe just help me feel a little more relaxed," she said.

Within half an hour, Constand found herself unable to walk. Cosby then took her to his couch and assaulted her. "My mind is saying, 'Move your hands. Kick. Can you do anything? I don't want this. Why is this person doing this?' And me not being able to react in any specific way," she said. "So I was limp. I was a limp noodle."

"I was crying out inside, in my throat, in my mind, for this to stop. And I couldn't do anything," she continued.

After the assault Constand eventually came to, and said Cosby gave her breakfast before driving her home.

Years later she came forward with her allegations. The first trial against Cosby in 2017 resulted in a mistrial. But in April of 2018 the once beloved comedian was convicted on three counts of assault. He could face a maximum of 30 years in prison.

The full interview, titled "Bringing Down Bill Cosby: Andrea Constand Speaks," airs Friday at 10 p.m. ET. on NBC.
