PEMBROKESHIRE residents are being drawn back nearly half a century in time with the launch of a new true crime podcast, Crime Next Door: Death on the Farm. This six-part series, produced by BBC Cymru Wales, re-examines one of the county’s most haunting unsolved cases: the brutal slaying of an elderly brother and sister in the quiet village of Llangolman.

In December 1976, the bodies of Griff and Patti Thomas were discovered in their remote farmhouse by a local postman. The violent nature of their deaths shocked the tight-knit community, and a wave of fear swept through the village as residents grappled with the terrifying notion that a killer was in their midst.

At first, suspicions centred on an outsider, a stranger who had invaded their peaceful rural life. But as the days passed, a more unsettling theory emerged, suggesting the possibility of a killer much closer to home. The case, which remains unsolved, has continued to cast a shadow over Llangolman, and the lack of closure has kept the tragedy alive in the memories of those who lived through it.

Crime Next Door: Death on the Farm seeks to answer the burning questions that have lingered for nearly 50 years: Did the police miss crucial evidence? Was justice ever truly served? And why does this case still matter so much to the people of Pembrokeshire?

The podcast features interviews with first-hand witnesses, members of the Llangolman community, and modern-day experts who revisit the evidence with fresh eyes. Narrated by actress Bettrys Jones and produced by Darrell Brown, the series aims to piece together the fragmented story and explore the lasting impact of the murders on the village.

Producer Darrell Brown spoke about the unique connection the community still feels to the case: “It’s unusual to find a case that remains such a topic of conversation for a community, but this one the people of Llangolman refuse to forget. It was a real privilege to tell their story and shine a light on a case that still casts a shadow on the village. We look forward to seeing how audiences respond, and to seeing how the case develops in the coming weeks and months.”

BBC Radio Wales Commissioner Bridget Curnow added: “Hearing the story directly from the voices of the community of Llangolman and their dedication to getting the closure they so want and need is so powerful. The fact that the community is still so dedicated 50 years on shows just how baffling this story is.”

Episode one of Crime Next Door: Death on the Farm is now available on BBC Sounds, with subsequent episodes set to release weekly. However, listeners should be aware that the series contains details that some may find distressing.

For those in Pembrokeshire, this podcast offers more than just a retelling of an old crime—it’s a chance to revisit a story that continues to resonate deeply within our community, and perhaps, to finally find some answers.
