On the night of 22 March 2017 Mr Day was discovered collapsed in a cubicle in the toilet block of the prison wing where he was placed. There was cold water gushing over him from a broken pipe to the toilet cistern which had likely broken during his collapse. The attending prison officers could not detect a pulse or breathing. The senior officer also believed him to be in a state of rigor mortis and considered he was dead. Factors cited by the officer for the belief that rigor mortis was present were: cold body temperature; pallor; the neck and wrist appearing firm when a pulse was felt for. However, it is not apparent that those were good reasons to consider rigor mortis was present as Mr Day was not moved and had been exposed to cold running water, and it was very unlikely that there had been sufficient time for this to have occurred.  

No CPR was attempted, and Mr Day was left in-situ, without being moved at all until an attending paramedic, who had arrived approximately 15 minutes after the officers first attended Mr Day, pulled him into the corridor and began CPR and subsequent advanced life – support, after which there was a return of spontaneous circulation. Mr Day was taken to hospital but went into a further cardiac arrest and died in the early hours of the morning of 23 March.

On the post-mortem and circumstantial evidence Mr Day’s cause of death was found to be 1a Toxic Effects of Synthetic Cannabinoids.[REDACTED]

The jury found and recorded that:  
Prison staff who attended Mr Day on the night of 22 March 2017 when he was found collapsed in the toilet cubicle should have performed CPR on him because: –
 
CPR should be attempted in all situations excluding certain extreme circumstances.
 
Staff were unqualified to recognise the signs of rigour mortis which was one of the exclusions.
 
Preservation of life should always be the primary goal.
 
Although the jury finds that the prison staff should have performed CPR, the jury does not find on the evidence that this omission contributed to Mr Day’s death.
 
The first bullet-pointed reason given by the jury relates to the HMP Sudbury Staff Information Notice at the time (the current Notice is the same), Guidance to support the decision-making process of whether to perform CPR in prisons. The guidance stated that: Resuscitation MUST be started on all people who are found not breathing and/or pulseless unless one of the following reasons/circumstances applies: Hypostasis/Lividity; Rigor Mortis; Decapitation; Massive Cranial and Cerebral Destruction; Incineration; Traumatic Hemicorporectomy; Decomposition/Putrefaction.
 
Three of the four prison staff who attended Mr Day were first aid trained, this included training in performing CPR. The training did not and still does not include assessing for and identifying rigor mortis, or verification of death.
 
HMP Sudbury is an open prison and does not have seven day a week 24-hour healthcare staff presence.
 
On the evidence it was quite possible that Mr Day had reached a point, by the time the prison officers attended him, where CPR would not have prevented his death, notwithstanding the clear opportunity for this to have been attempted.

The current CPR guidance does not appear to be appropriate for those prisons without 24-hour healthcare staffing, and in my view presents the real risk that future deaths could occur unless action is taken.
