According to the "Roles and responsibilities of SOC officers" which includes a scientific pathologist -Craig, who appeared to have done nothing more and nothing less than the basic requirements, was a GP - who carries out the post mortem, the medical attendant isn't required to give cause of death. He noted gun shot wounds in all victims. He didn't count them. Such was not in his remit. Such fell within the remit of a scientific pathologist, the services of whom, in this case -for some unknown reason- were dispensed with. PV found this oversight odd, perhaps even insulting?
