Bill Cosby has been denied parole as a result of his refusal to participate in sex offender treatment. The Pennsylvania State Parole Board declined Cosby’s parole request on May 11, according to a board letter provided to Oxygen.com. The letter states that Cosby didn’t participate in "a treatment program for sex offenders and violence prevention," and that he failed “to develop a parole release plan.” Spokesperson Laura Treaster told Oxygen.com via email on Friday morning that in order for Cosby to possibly get parole he must “successfully participated in/successfully completed a treatment program for sex offenders and violence prevention,” maintain a “clear conduct record” and receive a “favorable recommendation for parole from the DOC.” “Mr. Cosby is to be reviewed again upon completion of programming as indicated by recent DOC assessment,” Treaster stated. “There is no set timetable for this to take place.” Cosby was convicted in 2018 of drugging and sexually assaulting Andrea Constand in 2004. He is currently behind bars, serving a sentence of three to 10 years. While he was convicted of one assault, more than 50 women had come forward alleging that Cosby had drugged and sexually assaulted them over the course of decades. A statement was released on all Cosby's official social media accounts on Thursday by a representative for the actor who said that the parole board's decision "is not a surprise to Mr. Cosby, his family, his friends and/or his legal team." "It was brought to our attention by Mr. Cosby that over the past months, members of the PA State Parole Board had met with him and empathically stated, 'if he did not participate in SVP [Sexually Violent Predator] courses that his parole would be denied,'' the statement reads. It goes on to state that the 83-year-old has “vehemently proclaimed his innocence and continues to deny all allegations made against him, as being false, without the sheer evidence of any proof.” The statement says that Cosby “continues to remain hopeful that the Pennsylvania State Supreme Court will issue an opinion to vacate his conviction or warrant him a new trial." Cosby’s maximum sentence date is for the fall of 2028, Treaster told Oxygen.com. By that point he would over 90 years old.
