My DGF had heart failure and was discharged from the cardiologist around 92 or 93 as there was nothing further he could do. He went to his GP after a "funny turn" and was advised to pack a bag and go to hospital. He - presumably - had a massive heart attack whilst packing: the person with him called an ambulance, but he was pronounced dead at the hospital. He was 96.
My parents arrived at the hospital to find the police waiting for them, and the police subsequently asked for access to his home. My DGF was also sent for PM.
They were told that this was routine, but it was my impression that when a very elderly person with an extensive medical history has seen the GP on the day of their death, there's usually no PM. Although DGF died suddenly, his death wasn't unexpected, based on what the cardiologist had told him about his prognosis several years earlier, and of course, because of his age.
Is it normal that police would be in attendance in A and E in this type of case? And normal to check the home and order a PM?
DF was asked to be present by the police whilst they looked at DGF's body. It all just seemed a bit odd. DM (his daughter) was devastated, of course, so I didn't mention that it seemed unusual - but in your experience, do you do a lot of PMs on the very elderly who die in similar circumstances?
I agree with you that it seems unusual for your grandfather to need a post mortem in these circumstances (given his past medical history), but is up to the individual GP as to whether they are willing to issue a death certificate. If a death is referred to the Coroner then the information required will be gathered by police officers, that is the reason why they were in attendance. They hopefully act sensitively in that situation and would explain that they were acting for the Coroner and that there was no criminality involved. Sorry you've had an upsetting experience.
In Scotland your grandfather would be a good candidate for a 'view and grant', where the pathologist reads the history, examines the body externally to look for injuries and if satisfied can issue a death certificate, but this is not included in the laws of England and Wales and all cases proceed to full post mortem examination.
