A man who shot his wife’s lover in a cold-blooded murder has been jailed for life.

Andrew Jones, 52, lured Michael O’Leary, 55, to a farm in Carmarthenshire, south Wales, after discovering they had been having an affair.

Jones used a “secret” mobile phone belonging to wife Rhianon, 51, and asked to meet up for a cuddle.

Mr O’Leary turned up at Cyncoed Farm in January and was shot in the face with a .22 Colt rifle.

He begged "Please don't do it, Jones", but his pleas for mercy were ignored.

Jones made the dad-of-three's disappearance look like suicide and burnt his remains in a rusty oil drum – even holding a funeral service for his friend of 25 years.

He then drove his victim's Nissan Navara to a riverside car park where he sent messages purporting to be from Mr O'Leary to his wife and children, saying "I am so sorry x", before cycling back to the farm.

Jones used a forklift truck to load Mr O'Leary's body into his wife's car and took it home to Camarthen where he destroyed it.

The site manager's body has never been found, and forensic scientists have only ever recovered a small piece of his intestine from the oil drum in a yard adjacent to his home.

Dyfed-Powys Police were alerted by Mr O'Leary's worried family after receiving the text messages.

They launched a missing person inquiry and arrested the self-employed builder after he admitted luring his love rival to the farm.

The shooting was a culmination of a deteriorating relationship between the married couple, as the increasingly paranoid dad-of-three used his own teenage daughter to spy on her mum – having learnt the affair was not over.

Today, October 19, he was handed a 30-year sentence at Swansea Crown Court, having been convicted of murder by a jury with a majority 11 to one verdict.

Jones must serve a minimum term of 30 years before he can be considered for parole.

Judge Mrs Justice Jefford told the killer: “Michael O’Leary did something wrong but he did not deserve to pay for that with his life. All accounts of him is of a man who lit up the room and played a central role in the lives of his family.

“Your family stands by you. You are more than fortunate in that. The impact of your actions in their lives has also been devastating. They feel ostracised from the community from where they live.

“Your wife still talks about you as the love of her life and your children talk about you in glowing terms.”
