Two baby triplets found dead 'with carbon monoxide poisoning', third brother survives

Two baby triplets that died in their sleep in the UK were reportedly poisoned accidentally by carbon monoxide, it has been claimed.

Sarah Owners, 29 and a single mother, found two of her five-month-old boys not breathing when she checked on them over the weekend, the Mirror reports.

The two triplets - Charlie and Noah - were pronounced dead at hospital while the third, Ethan, was unharmed.

Nieghbours claim they were told by the boys' grandfather that the possibility they died by carbon monoxide poisoning, maybe due to a faulty heater, had been ruled out.

A GoFundMe page was set up for the family to help "take the financial stress" off Ms Owens.

A friend of Ms Owen said "she loved those boys".

"They had a difficult start because they were very light but they were doing very well. She's just devastated."

Neighbour Anne Way, 64, told The Sun "It was awful".

"I saw a firemen carrying one of the babies out in his arms. The poor little thing was grey in the face, I would say he was already dead."

The babies were born prematurely but were said to be "doing so well".

Police have so far refused to comment on the claim they died from carbon monoxide poisoining.

"At 10.05am emergency services attended an address in the Wildmill area of Bridgend to a report of two young children, two of triplets, who were found not breathing," a South Wales Police spokesperon said.

"The five month old children were conveyed to hospital where tragically they were later pronounced deceased.

"There are no suspicious circumstances surrounding the deaths which are being treated as a tragic accident."

It is believed one line of inquiry is whether sudden infant death syndrome (SIDS), also known as cot death, was involved, The Sun reports.

A Home Office pathologist has been called in to carry out a post mortem examination on the two babies.
