A paramedic called to treat a notorious criminal gunned down in his garden in Essex raised doubts about the cause of his fatal injuries, a report said.
John "Goldfinger" Palmer, who previously ran a jewellery business in Bristol and lived in Bath, was initially thought to have died from natural causes in 2015. It took a week to establish he had been shot six times.
A case review revealed a paramedic told police he doubted the conman's wounds were from recent keyhole chest surgery.
But police officers at the scene were "not concerned", the report said.
