Bill Cosby, 83, Is Shown Grinning in New Mugshot Comedian/Actor Billy Cosby has been serving time since September 2018 in the State Correctional Institution in Phoenix, PA for sexual assault, which happened in 2004. Periodically, the prison takes new pics of inmates since their appearance changes. Cosby was up for a new shot on September 4. The new mugshot shows Cosby disheveled with a smile and wearing a facial mask around his neck. The comic has changed a lot in two years. Do you think prison has taken a toll on Cosby’s appearance? Or do you think it’s just old age or stress?
