John Allen Martin Henderson was found dead in his bunk at HMP Rochester on 27 May 2021. The inquest recorded natural causes, namely ischaemic heart disease, following a fatal haemorrhage into the wall of the left circumflex artery. Concerns included delayed medical investigations, the absence of a welfare check at the start of the day, and a lack of a clear process for sharing relevant medical information with front-line prison staff.
