Richard Pryor's shockingly honest, no holds barred performances revolutionised American comedy. And his no holds barred attitude continued off screen with his monstrous appetite for drink, drugs and sex. But during the last part of his life Pryor was struck down with a debilitating illness which left him paralysed and unable to speak. Then, on December 10th, 2005, Richard Pryor dies from a cardiac arrest. But what killed him? Was it his wild past catching up with him? His debilitating illness? Or something else all together? Forensic Pathologist Dr. Michael Hunter will be examining Richard's medical records to determine precisely was caused the death of this much loved comedian.
