The mother of one of Bill Cosby’s accusers wrote a letter to his wife, Camille, over the string of sexual assault allegations against the comedian, urging her to speak the truth. Thirty women have so far come forward with sexual assault and rape allegations against the 77-year-old comedian.

Jennifer Kaya Thompson was introduced to Cosby by her parents in the late 1980s, The Associated Press (AP) reported. Thompson’s parents were reportedly looking for guidance for their daughter’s aspiring modeling career. However, Cosby's unwanted sexual advances made her lose focus on her career, Thompson, who was 17 when she met Cosby, told AP. In a video interview with AP, Thompson’s mother, Judy, talks about the letter she wrote to Cosby’s wife, believing that Camille, a mother of three daughters, would be understanding.

Judy has not yet received a response from the actor's wife, and Cosby’s spokesman also did not respond to comments regarding the letter, AP reported. Earlier this month, two more women -- Linda Brown and Lise-Lotte Lublin -- publicly accused Cosby of drugging them when they met him years ago.

On Monday, Cosby released a brief video message to his fans -- his first since the sexual assault allegations resurfaced -- mentioning an upcoming show. Cosby has been criticized by many for not addressing the scandal directly.

Meanwhile, Cosby's lawyers are seeking to dismiss defamation lawsuits filed against the actor. The lawsuits claim that the actor's representatives publicly called his accusers “liars,” but Cosby's lawyers have denied the allegations. The first lawsuit was filed by Tamara Green followed by Therese Serignese and Linda Traitz.
