One detail that jumped out at me was the hospital gown. He wouldn't have been wearing a gown in prison, if he was found dead, he would be wearing an orange jump suit. So why would a cadaver need a gown ?  Why would a corpse being prepared for an autopsy need a gown ? From the photos it looks like the gown is tied at the back, his arms are through the sleeves. If it is for modesty/privacy, wouldn't a sheet be easier for an autopsy ?
