I'm in Ireland and believe the process may be similar.
There will have to be an autopsy and there will be a public inquest done even though the death may be obvious. Regardless of the wishes
Depending on how busy the coroner is will determine how long before the body is returned to family
The police will be called to the scene and will remove evidence, such as a note, phone etc
Any items removed will be returned to family at a later stage, normally once the inquest has been completed.
with regards to bank accounts etc it would be much easier to lift money out and have cash in a drawer.
The next of kin is normally the one tasked to inform the likes of banks, dentists and so on of the death.
Also once the next of kin receives the death certificate, there is a slip which can be filled in which stops mail arriving for the deceased.
in the case of my brother, the police were extremely compassionate and any organisation that we had to deal with were also the same.
I hope this info helps you.
