I feel as though we are running out of time
On a Sunday afternoon in Merthyr Tydfil, a 51-year-old man in the grip of a rare and dangerous medical crisis slipped away from the hospital meant to hold him safe, and the people who love him have been searching ever since. Carwyn Thomas suffers from thyroid storm, a condition that does not pause for absence or distance, and every hour without treatment narrows the margin between recovery and catastrophe. His disappearance from Prince Charles Hospital is not merely a missing persons case — it is a race between human effort and biological urgency, played out across the streets and hills of south Wales.
- A man in active medical psychosis walked out of a Welsh hospital unaccompanied, and his family only learned he was gone when silence replaced the call they were waiting for.
- Thyroid storm does not relent — without medication and clinical care, Carwyn Thomas's heart, temperature, and mind remain under siege from his own body.
- His sister Della Jones has been out in the dark, taping posters to walls, translating private terror into a public plea because no other option remains.
- Police have issued a formal appeal, asking anyone who spots a man in grey clothing — grey jumper, grey jogging bottoms — to call 101 or Crimestoppers on 0800 555111, quoting occurrence 2600139178.
- The family's message is unambiguous: time is running out, the risk of serious harm is real, and they are doing everything they can to make a missing man visible before his condition becomes irreversible.
Carwyn Thomas left Prince Charles Hospital in Merthyr Tydfil on Sunday, May 3rd, and has not been seen by his family since. The 51-year-old from Ystradgynlais walked out through the maternity ward exit while in the grip of thyroid storm — a rare and life-threatening emergency in which the thyroid floods the body with excess hormone, driving fever, a racing heart, severe agitation, and in Thomas's case, full psychosis.
He had been brought to hospital by paramedics after police responded to reports of disturbing behaviour in Brecon town centre. He arrived alone, and his family received no further word. His sister Della Jones has since been out late into the night, posting appeals around the town. "We are frantic, so worried," she said. "He is at a high risk of serious harm and he is vulnerable in this state. I feel as though we are running out of time."
The urgency is medical as much as it is emotional. Thomas suffers from Graves' disease, an autoimmune condition that has turned his own immune system against his heart. Without the stabilising care of a hospital, his body remains in active danger — a danger that compounds with every passing hour.
South Wales Police are appealing for information. Thomas, who goes by Carwyn, was last seen wearing a grey jumper and grey jogging bottoms. Anyone with information is asked to call 101 or contact Crimestoppers anonymously on 0800 555111, quoting occurrence number 2600139178. The search continues.
Carwyn Thomas walked out of the Prince Charles Hospital in Merthyr Tydfil on Sunday afternoon, May 3rd, and his family has not seen him since. The 51-year-old man from Ystradgynlais left through the maternity ward exit, and within hours his sister Della Jones was putting up posters around the town late into the night, her voice tight with fear.
Thomas arrived at the hospital after police responded to reports of disturbing behavior in Brecon town centre. He was in the grip of thyroid storm—a rare, life-threatening medical emergency where the thyroid floods the body with excess hormone, forcing metabolism into overdrive. The condition produces a cascade of symptoms: fever, a racing heart, severe agitation, delirium. When paramedics found him, he was in psychosis. They transported him to hospital alone, and that was the last his family heard from him.
Thyroid storm is not something a person can simply walk off. Graves' disease, the underlying condition Thomas suffers from, means his own immune system has turned against his heart. Without treatment, without medication, without the stabilizing care of a hospital, his body is in active danger. His sister knows this. She knows the clock is running.
"The ambulance came and a paramedic said he was in psychosis," Della Jones said. "They took him to hospital unaccompanied and we have not seen him since. We are frantic, so worried, that goes without saying. He is at a high risk of serious harm and he is vulnerable in this state. I feel as though we are running out of time, we are doing everything we can to get the message out."
South Wales Police have issued an appeal for information. Thomas was last seen wearing a grey jumper and grey jogging bottoms. He is 51 years old. His full name is David Carwyn Thomas, though he goes by Carwyn. Police are asking anyone who may have spotted him to come forward—to call 101, or to contact Crimestoppers anonymously on 0800 555111, quoting occurrence number 2600139178.
For his family, the urgency is not abstract. Every hour that passes is an hour their brother is without the medical intervention his body desperately needs. Della Jones and others have been out in the evening darkness, taping posters to walls, trying to turn a missing person into a visible presence in the community. They are doing what families do when the system has failed them: they are taking to the streets themselves, asking strangers to look, to remember, to call.
The search continues. The appeal is active. And somewhere in south Wales, a vulnerable man with a life-threatening condition remains unaccounted for.

A Conversa do Hearth Outra perspectiva sobre a história
Why did he leave the hospital? Was he trying to escape, or did something else happen?
We don't know. The source doesn't say whether he left of his own volition or if there was a gap in supervision. What we do know is that he arrived unaccompanied after the police found him in crisis, and then he was gone. That's the gap.
Thyroid storm sounds serious. How serious are we talking?
It's a medical emergency. High fever, heart racing, the mind breaking apart into delirium. Without treatment it can be fatal. He needs medication, monitoring, stabilization. Walking around in that state is walking around in active danger.
His sister said they took him unaccompanied. Is that normal procedure?
That's the question nobody's answering in this story. It seems unusual, but the reporting doesn't explain the hospital's protocol or reasoning. What's clear is that the family sees it as a failure—he arrived in crisis, alone, and then disappeared.
What does thyroid storm actually do to a person's mind?
It floods the system with hormones. The metabolism goes into overdrive. The brain can't regulate itself properly. You get severe agitation, delirium, psychosis—which is exactly what the paramedic observed when they found him in Brecon. He wasn't thinking clearly. He still isn't, if he's untreated.
Why is the family's fear so palpable in this story?
Because they understand the timeline. Every hour without treatment is an hour the condition worsens. They're not just looking for a missing person—they're racing against a medical clock. And they're doing it alone, with posters and phone calls, because the hospital didn't keep him safe.
