Robin Williams was one of the funniest and most gifted comedians of his generation. He burst to prominence in 1978 in the hit TV sitcom Mork & Mindy and won an Oscar for Good Will Hunting in 1997. But just before midday on 11th August 2014, he’s found hanging from a belt secured to a closet door in his home in Tiburon, California. Now, Dr Richard Shepherd is piecing together the events of Robin Williams’ last hours and evidence from the autopsy report to uncover what triggered this suicide.
