Camille Cosby Claims Disgraced Husband Was Sent to Prison on 'Falsified Evidence'

Bill Cosby‘s wife, Camille, claims her husband’s three-to-10-year prison sentence for sexual assault is the result of “falsified” evidence that “denied his right to a fair trial.”

As she did following her husband’s convictionlast April on three felony charges of aggravated indecent assault against Andrea Constand in 2004, Camille Cosby on Tuesday claimed the outcome was the result of improper conduct by the Pennsylvania prosecutor, Kevin Steele.

“We have now learned and will prove that Bill Cosby was denied his right to a fair trial because the DA of Montgomery County, Kevin Steele, used falsified evidence against him,” she said in a statement released to PEOPLE through Bill Cosby’s publicist.

She claims that Constand’s mother, Gianna Constand, “surreptitiously and illegally” recorded a 2005 phone call between herself and Cosby “without his knowledge or consent,” and that the recording of that conversation played for jurors during Cosby’s trial was altered, according to a private forensic analysis of the recording that was obtained by the defense team.

She did not elaborate on the specific statements made in the recording, but said an unnamed online publication reported that the original recording “contained information that would exonerate Mr. Cosby.”

“Mr. Cosby’s defense team will be filing a motion seeking immediate relief for the prosecution’s use of this falsified evidence,” said her statement. “The DA’s use of this falsified audio clip at trial is deeply prejudicial, yet it represents just one of many issues that resulted in the denial of Mr. Cosby’s right to a fair trial.”

In response, Steele said, “If that’s what they’ve got, it’s beyond a Hail Mary,” according to the Associated Press.
