Wales (Wales Times) October 28, 2026 – A man with a history of mental health difficulties died after being allowed to leave a Welsh psychiatric unit despite a warning message about self-harm that was not shared with the doctor responsible for his care, an inquest has found.

Liam Griffith Williams, aged 40, had been receiving treatment at the Hergest Unit at Ysbyty Gwynedd when he was granted leave from the ward. He was later found in a storage facility in Star, near Gaerwen, before being returned to hospital. He died on October 8, 2025, three days after the events that led to the inquest.

The inquest, held in Caernarfon and reported by WalesOnline, examined whether opportunities existed to intervene before Mr Williams left the unit. Assistant coroner Sarah Riley concluded that critical information concerning his welfare had not reached the attending doctor, leaving that clinician without information that could have shaped the decision to allow him leave.

Why was the warning message not passed on?

According to evidence heard at the inquest, Mr Williams sent a message to his wife on October 4, 2025, indicating that he intended to harm himself. That message was communicated to a call handler at the Hergest Unit and recorded in the ward log.

However, as reported by WalesOnline, the information was not relayed to a doctor. The coroner found that this meant the message was “unavailable” to the attending doctor when decisions were being made about Mr Williams’ care and possible leave from the unit.

The doctor told the inquest that, had he been made aware of the self-harm message, he would have engaged further with Mr Williams about it. The clinician also indicated that the decision to allow Mr Williams to leave depended on his response during discussions.

What did the coroner find?

Assistant coroner Sarah Riley determined that Mr Williams was permitted four hours’ leave on October 4, 2025. The following day, October 5, a registered mental health nurse reported that he appeared well presented and was “looking forward” to seeing his family. She said she had no concerns, and he was subsequently allowed unescorted leave.

Mr Williams was later found in a storage facility in Star, near Gaerwen. He was returned to Ysbyty Gwynedd for treatment but died three days later, on October 8, 2025.

Ms Riley recorded that the cause of death was a hypoxic brain injury due to hanging. In a narrative conclusion, she said there had been missed opportunities for the health board to review and escalate Mr Williams’ situation.

As reported by WalesOnline, the coroner said Mr Williams’ death occurred in the context of missed opportunities for the health board to review and escalate concerns. She also found that Betsi Cadwaladr University Health Board did not share important information about Mr Williams’ comments to his wife, meaning the attending doctor did not have access to it.

What did the health board say?

Teresa Owen, director of health professionals and health science at Betsi Cadwaladr University Health Board, acknowledged the inquest’s findings and recommendations. She offered condolences to Mr Williams’ family on behalf of the health board.

“We accept the coroner’s conclusions and recommendations and recognise the necessity of learning from this case,” Ms Owen said, as reported by WalesOnline.

She said that, since the incidents, the health board had strengthened its procedures relating to risk assessment, communication between clinical teams, care planning and clinical oversight. Ms Owen also said measures had been taken to improve the involvement of families and carers in care planning, so that their concerns are properly considered.

“We will continue to monitor these improvements to ensure they are effectively integrated into practice,” she said.

What does the narrative conclusion mean?

A narrative conclusion is a form of coroner’s finding used when the circumstances of a death do not fit neatly into a single standard category. Rather than recording a simple conclusion such as suicide or accident, the coroner sets out the relevant facts and circumstances surrounding the death.

In this case, Ms Riley’s narrative conclusion recorded that Mr Williams died from a hypoxic brain injury caused by hanging, while also identifying missed opportunities by the health board to review and escalate his situation. The finding did not, according to the reporting, amount to a finding of unlawful killing; it focused on failures in the sharing and escalation of risk information.

Why was the information significant?

The inquest heard that the message from Mr Williams to his wife was recorded by a call handler and entered into the ward log. The central issue was therefore not whether the concern had been received, but whether it reached the clinician making decisions about his care.

The attending doctor’s evidence, as reported by WalesOnline, indicated that knowledge of the message would have led to further engagement with Mr Williams. This made the failure to pass the information on a significant part of the coroner’s findings.

The case highlights the importance of communication between call handlers, ward staff, nursing teams and doctors, particularly where a patient has a known history of mental health difficulties and has raised concerns about self-harm.

What changes has the health board made?

Betsi Cadwaladr University Health Board said it had made changes after the events surrounding Mr Williams’ death. According to Ms Owen’s statement, these changes concern four main areas:

• Risk assessment procedures.
• Communication among clinical teams.
• Care planning.
• Clinical oversight.

The health board also said it had taken steps to improve family and carer engagement in care planning. Ms Owen said the board would continue monitoring the changes to ensure they are embedded in day-to-day practice.

Background of the development

The Hergest Unit is a mental health facility at Ysbyty Gwynedd in uk/local/bangor/">Bangor, operated by Betsi Cadwaladr University Health Board. Mr Williams, who lived in Llanfairpwll on Anglesey, had a background of mental health challenges and was being treated at the unit before his death.

The events began on October 4, 2025, when Mr Williams sent his wife a message indicating that he planned to harm himself. The concern was received by a call handler at the Hergest Unit and logged, but was not passed to a doctor. He was granted four hours’ leave that day. The next day, nursing staff reported no concerns and he was allowed unescorted leave.

He was later found in a storage facility in Star, near Gaerwen, and returned to Ysbyty Gwynedd. He died on October 8, 2025. The inquest in Caernarfon, reported by WalesOnline, concluded that there were missed opportunities to review and escalate his care, and that the health board had not ensured the relevant information was available to the attending doctor.

How could this affect mental health patients and families?

For patients receiving mental health care in Wales, the case may increase scrutiny of how concerns raised by relatives are recorded, escalated and communicated to responsible clinicians. Families and carers may expect clearer confirmation that urgent welfare messages have reached the clinical team responsible for a patient’s care.

For health boards, the coroner’s findings and the health board’s response may reinforce the need for robust handover systems, clear escalation routes and documented follow-up when self-harm concerns are reported. The health board’s stated reforms—covering risk assessment, clinical communication, care planning, oversight and family involvement—will likely be monitored for effectiveness.

For people in North West Wales who use mental health services or support relatives in hospital, the development underlines the importance of raising concerns promptly and asking for confirmation that they have been passed to the appropriate clinician. It also shows that inquests can lead to formal recommendations and institutional changes intended to reduce the risk of similar communication failures.
