postmortem

The postmortem report cited cardiorespiratory shock from electrical current at multiple sites as the cause of death, occurring 36 to 72 hours before the autopsy conducted on 1 May.

The coroner's office in Surrey told the BBC that after a postmortem, it had determined that Kapur died of natural causes.

Any postmortem needs to examine not just the message, but also the medium.

A postmortem of Mr Rickards' body showed he had been strangled weeks before his death and was also recovering from recent rib fractures, according to the CPS.

The department said that specialist postmortem examinations are not always required, but where they are, this is mostly carried out in Dublin with some regional services in Cork and Galway.
