I would have thought that if somebody had been shot 6 times there would be some extra holes and probably some gooey mess, even if the guy had just had surgery.
Palmer had recently had surgery and it was initially thought he had suffered a cardiac arrest.
It is thought that this surgery was common knowledge among friends and family and could have been deliberately used to disguise the injuries.
A week later, a post-mortem examination found the convicted conman had been shot in the chest six times, which prompted an investigation by the police watchdog.
