"Significant failings in care " contributed to the death of a 'lovely, vibrant' teenager, a Senior Coroner has concluded.

Locket Williams, described by their family as "a lovely person with a huge character", was just 15 years old when they tragically killed themselves in September 2021.

Senior Coroner Richard Travers concluded that there were a number of key failures by Surrey and Borders Partnership (SABP) NHS Foundation Trust’s Children and Adolescent Mental Health Services (CAMHS) which contributed to the death of the vulnerable teenager, who goes by they/them pronouns. The three-week inquest concluded Friday 31 May.

Locket’s older sister, Emily, said: “Hearing the coroner recognize what we have believed for three long years—that failures by CAMHS contributed to Locket’s death and ultimately meant Locket lost all hope—is heartbreaking.

“We’re thankful for the Coroner’s respect for Locket’s identity, which was so important to them, and we sincerely hope this process will help prevent more tragic deaths like Locket’s in the future.”

Described by their family as “vibrant” with a “massive heart”, Locket “brought colour to everything they participated in” their family said.

They had a long history of mental health difficulties, resulting in self-harming behaviours and three previous suicide attempts throughout within seven months of 2021.

Evidence heard at the inquest highlighted “illogical conclusions” that Locket was deemed “low risk” by clinicians, despite their ongoing suicidal ideation and three suicide attempts in close succession, the family's lawyers reported having heard in court from the coroner.

Coroner Travers found that Locket’s high risk of suicide was “underestimated” by clinicians, as there was an “insufficient account” of Locket’s long-running risk, which meant Locket did not receive the treatment they needed.

Commenting on the Coroner's findings, the family’s solicitor, Elle Gauld from Simpson Millar’s public law team, said: "Given Locket’s three suicide attempts and deteriorating mental health, CAMHS’ approach repeatedly defied logic and palpable evidence of suicidality, bypassing the patient's express wishes and placing an unrealistic burden on a family already in crisis. Treatment was not commenced in a timely manner”

Long waiting lists for Cognitive Behavioural Therapy (CBT) and a shortage of therapists meant that, although clinicians all agreed CBT was necessary, Locket remained at home. Without access to the required support and treatment, their mental health continued to deteriorate, the lawyers for the family said.

Coroner Travers said there was a ‘failure’ to assess the likelihood Locket could be kept safe while waiting eight months for Cognitive Behavioural Therapy (‘CBT’), a treatment she was ready and willing to engage in.

Failures in communication between social services and CAMHS were also identified, leading to crucial information being missed in Locket's assessment and care. CAMHS failed to attend Core Groups meetings held by social services to protect Locket, as a vulnerable child.

Locket was passed from service to service, with no continuous care from the same clinicians or who was responsible for Locket’s care, lawyers said.

Speaking of the family’s loss, Locket’s mother, Hazel Williams, said: “We hope the lessons learned from their death highlight the urgent need for change and prevent future tragedies. We are grateful for the thoroughness of this inquest and the potential for positive changes in managing mental health services for young people."

SABP has 56 days to respond to the senior coroner’s findings. Coroner Tavers has asked the NHS Trust to report whether there is now a system in place to ensure that young people referred to CAMHS are seen and treated promptly, and that clinicians are acting in accordance with the Trust’s guidelines.

A Surrey and Borders Partnership NHS Foundation Trust spokesperson said: “We are extremely saddened by the tragic death of Locket Williams and our deepest sympathies go to their family and friends.

“We are carefully reflecting on the Coroner’s findings and the questions we have been asked and will respond within the given timeframe.”
