Cosby was in court Tuesday for a pretrial hearing. He was charged with three counts of sexual assault surrounding an alleged encounter with former Temple University basketball player Andrea Constand in 2004.

Constand claims that Cosby gave her pills that he said were an "herbal supplement" and proceeded to fondle her breasts and penetrate her vagina with her fingers, after she was rendered incapacitated by the drugs.

Though Cosby is only being tried for assaulting Constand, he could be greeted by 13 other women who claim that he attacked them in a similar manner.

Hours before the Tuesday pretrial hearing in Pennsylvania, Montgomery County District Attorney Kevin Steele filed a motion to include the testimonies of these 13 women. The motion describes incidents dating back to the late 1960s.

Steele's motion intends to use the testimonies of 13 women identified as prior victims to establish a larger pattern of abuse.

Steele's motion cites Pennsylvania’s Evidence of Prior Bad Acts rule, which can permit testimonies that illustrate a "common plan or scheme," the motion (PDF) explains.

“We spent a lot of time talking to people all over the country and outside the country,” Steele told reporters, according to the Los Angeles Times. “They have indicated they are willing to testify.”

“During the course of this case, the Commonwealth investigated nearly 50 women allegedly victimized by defendant,” the motion reads. “What became clear was that defendant has engaged, over the course of his lifetime, in a pattern of serial sexual abuse.”

"An individual who, over the course of decades, intoxicates women in a singular fashion with the intention of sexually assaulting them cannot be mistaken about whether or not those women are consenting to the sexual abuse," the motion continues. "And that is because the answer is so clear: they are not."

The motion goes on to detail thirteen alleged encounters.

Here's how the second and third victims described what happened, according to the motion:

Each alleged victim claims that she was sexually assaulted by Cosby after being drugged. There are other common threads: many of the accounts included in the motion are from women who were significantly younger than Cosby at the time the incidents allegedly occurred.

The eleventh alleged victim said she developed a friendship with Cosby leading up to the incident and felt that her trust was violated.

The thirteenth victim claimed to have met him professionally and said he offered to mentor her in a professional capacity — as did four of the other victims described in the motion.

At the pretrial conference, Judge Steven T. O'Neill said he would decide on Steele's motion at a future hearing and set a trial date for June 5, 2017, the Los Angeles Times reports.

The court may consider Pennsylvania's statute of limitations — 12 years — in making its decision.

Cosby's lawyers also claimed Tuesday that Steele — who promised to prosecute Cosby during his 2015 campaign to be elected as D.A. — is biased, and requested the trial be relocated elsewhere, Vanity Fair reports.

“Where would you go?” Judge O'Neil responded, according to the Los Angeles Times.

Cosby previously faced his accusers in the court of public opinion.

Thirty-five women accused Cosby of sexual assault in interviews with New York Magazine and he is facing 60 accusations total, the Washington Post reports.

Cosby could spend ten years in prison and face millions in fines if convicted.
