REGULATION 28: REPORT TO PREVENT FUTURE DEATHS

REGULATION 28 REPORT TO PREVENT FUTURE DEATHS

THIS REPORT IS BEING SENT TO:

1. 

, Chief Constable, Devon & Cornwall Police.

1

CORONER

I am Alison Longhorn, Area Coroner for the coroner area of the County of Devon,
Plymouth & Torbay.

2

CORONER’S LEGAL POWERS

I make this report under paragraph 7, Schedule 5, of the Coroners and Justice Act 2009
and Regulations 28 and 29 of the Coroners (Investigations) Regulations 2013.

INVESTIGATION and INQUEST

A coronial investigation was commenced on 9th March 2023 into the death of David John
Thompson, aged 46. The investigation concluded at the end of the inquest on 3rd
February 2026. The conclusion of the inquest was suicide, and the medical cause of
death was recorded as 1a) hanging.

CIRCUMSTANCES OF THE DEATH

On 6th March 2023, David Thompson went missing from his home address. He had a
history of low mood, had expressed thoughts of suicide previously, and had been
experiencing a number of challenging life events in the weeks before. His partner
reported him missing to the police and he was graded as a ‘medium risk’ missing
person. He was located the following morning,

CORONER’S CONCERNS

During the course of the inquest the evidence revealed matters giving rise to concern. In
my opinion there is a risk that future deaths could occur unless action is taken. In the
circumstances it is my statutory duty to report to you.

The MATTERS OF CONCERN are as follows.  –

(1) The inquest heard that when Mr. Thompson’s partner reported him missing to the
police, she was repeatedly asked (by both the 999 call handler and the attending police
officers) whether he had demonstrated any ‘suicidal ideation’. It was clear that she did
not fully understand what that meant, and as a result information which would have been
relevant to the consideration of the level of risk presented by Mr. Thompson going
missing was not recorded by the police.

(2) Furthermore, I heard evidence that the term ‘suicidal ideation’ was still being widely
used by the constabulary when asking questions of members of the public who were
reporting missing persons, and I am concerned that a member of the public may not
understand what is being asked of them and may not therefore respond appropriately.

(3) During the course of the inquest I heard evidence from 5 police officers and 2
members of police staff. When asked what their understanding of the term ‘suicidal

 ideation’ was, their answers were vague and inconsistent. There therefore appears to be
a lack of understanding by those employed by the police as to what the term means,
creating a danger that the risk posed by a missing person is not fully appreciated by staff
responding to a missing person report.

ACTION SHOULD BE TAKEN

In my opinion, action should be taken to prevent future deaths, and I believe you and
your organisation have the power to take such action.

Subject: Death of David John Thompson (ref: 15607320) 

Dear HM Coroner 

PREVENTION OF FUTURE DEATH RESPONSE FOLLOWING THE INQUEST 
INTO THE DEATH OF DAVID THOMPSON 

MATTERS OF CONCERN: USE AND UNDERSTANDING OF THE TERM 
“SUICIDAL IDEATION”  

I am writing in response to the Regulation 28 report into the prevention of future 
deaths notice, that was issued on 10 February 2026 and sent to the Chief Constable 
of Devon & Cornwall Police, James Vaughan. 

The Chief Constable has asked me to respond to this notice, as the matters of 
concern raised therein fall within my area of policing responsibility. Please therefore 
treat this correspondence as the Chief Constable’s formal response to the 
Regulation 28 Notice. 

The Chief Constable and myself want to take this opportunity to express our 
condolences to Mr Thompson’s family and friends. We are sincerely very sorry for 
their loss. 

Additionally, the Chief Constable and I also want to thank you for bringing the 
matters of concern set out in the Regulation 28 Notice to our attention. We welcome 
opportunities to give serious consideration to any matters of concern such as this 
with a view to improving the service that we provide the public, and to assist you and 
your coronial colleagues in your investigations. 

Devon & Cornwall Constabulary acknowledges the concerns raised regarding the 
use and understanding of the term ‘suicidal ideation’ within operational decision-
making and communications with members of the public.  

As a Force, we will continue to deliver refresher training to Control Room Staff to 
further strengthen their understanding of suicidality, associated risks, and the 
dynamic and fluctuating nature of such incidents.  

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 Guidance issued in 2024 clarified that the term ‘suicidal ideation’ refers to thoughts 
of suicide (with reference to publications within the Lancet, and commentary 
provided in open-source by the Samaritans within which ‘ideation’ relates primarily to 
‘thinking about suicide or could be making a plan to take their own life. This can 
range from a passing thought to a detailed plan’). This clarification has been further 
reinforced and incorporated into training and operational guidance that is being 
issued and delivered throughout 2026 – with specific emphasis on the wide variety of 
incidents and risks that the term encompasses.  

Training for Control Room supervisors and staff continue as part of ongoing 
refresher programmes. With greater focus, these sessions explore the definitions, 
meanings, and associated risks linked to suicidality. Staff are reminded that 
language used when assessing and communicating risks must remain clear, 
concise, and understood within its basic meaning.  

Whilst ‘suicidal ideation’ may be considered a clinical term in some contexts, the 
Force recognises that in emergency situations and when communicating with 
members of the public, it is often more appropriate to use plain language that is not 
prescribed or confined to a single definition. Accordingly, operational practice 
encourages the use of straightforward terminology such as ‘thoughts or feelings 
about suicide’ when discussing potential suicide risk.  

Officers and staff are also reminded that suicide risk can fluctuate rapidly, particularly 
where factors such as intoxication, significant trigger events, or access to means 
change (this list is not exhaustive). The Force recognises that over-reliance on rigid 
definitions, structured terminology, or scripted questions, may create false 
reassurance and could potentially increase risks. For this reason, operational 
messaging within Control Room refresher training and frontline operational guides 
prioritises the use of clear, accessible language and encourages open questioning to 
fully understand the circumstances being reported and avoid ‘language-driven 
information loss’.  

Control Room teams are therefore encouraged to use plain language and to ask 
broader exploratory questions, rather than relying on a single question relating 
specifically to ‘ideation’, when assessing risk.  

Consequently, the following actions have been taken: - 

1.  Continued emphasis on the use of plain language throughout Control Room 

refresher training which will continue to be delivered throughout 2026. 
2.  Formal clarification within 2024 guidance that the term ‘suicidal ideation’ 
simply means ‘thoughts or feelings of suicide’ – this continued to be 
reinforced. 

3.  Reinforcement of the above approach to frontline officers and staff through 
the introduction of operational guidance (Op Guides) relating to incidents 
involving Article 2 risks and suicidality.  

 
 
 
 
 
 
 4.  Recognition that ‘suicidal ideation’ is not a nationally standardised policing 

term; therefore, communications and training have been undertaken to ensure 
staff understand the broad spectrum of risk that the term may encompass. 

We have also undertaken some work with other Forces and have become aware of a 
‘Ovenstone criteria’ (A criteria formed in 1973 by Dr. Irene Ovenstone) Whilst 
predominantly an investigative method to assist in determining whether a death was 
likely to be suicide, it is also useful for determining suicidal risk and provides some 
evidence of suspected pre-suicidal criteria and we are actively exploring this use.  

Devon & Cornwall Constabulary remains committed to ensuring that officers and 
staff are equipped with the knowledge, language, and operational guidance 
necessary to identify and respond appropriately to individuals presenting with suicide 
risk.  

Yours sincerely,  

Assistant Chief Constable 
29th March 2026
