A man from Cwm Cou near Newcastle Emlyn has been sentenced to 35 years in prison after admitting the attempted murder of his infant daughter. The attack happened on 15 January 2025, when he was left alone with the baby for less than half an hour at a house in Y Ferwig.
Attack happened in minutes after father was left alone with baby
Police told Swansea Crown Court that Rhydian Lyn Rhys Jamieson “snapped” before throwing the child at a TV, placing her under a blanket and fleeing the house. He then sent a series of disturbing Snapchat messages and voice notes to friends and the baby’s mother, claiming he had killed the child and saying he was “finished”.
The baby’s mother rushed home after receiving the messages and found her daughter face‑down on a bed under a blanket. The child was breathing but had visible injuries and was taken to hospital for emergency treatment.
Officers who searched the room found the TV on the floor, blood stains on bedding and the baby’s clothing discarded nearby. Jamieson was arrested less than 30 minutes after the first 999 call. While being taken into custody, he told officers he could not believe he had tried to kill his daughter.
He later pleaded guilty to attempted murder and was sentenced today at Swansea Crown Court.
Mother describes ‘unimaginable’ impact on her daughter’s future
The baby’s mother said:
“What has happened has completely changed my life and my daughter’s life forever, as well as having a huge impact on my whole family.”
She told the court she now lived with daily fear about her daughter’s long‑term health, with medical experts still unable to say whether the child will ever walk, talk or live independently.
She added:
“Instead of enjoying my daughter’s first year of life, I now spend every day worrying about what the future holds. I feel robbed of the chance to just be a normal young mum.”
Police condemn ‘appalling act of violence’
Detective Chief Inspector Gary Williams, Dyfed‑Powys Police, said:
“This was an appalling act of violence towards a defenceless baby – his own daughter – who had been left in Jamieson’s care.”
He said the family had shown “remarkable strength” throughout the investigation and praised the officers who worked on the case.
Jamieson will serve 35 years in prison.
