Two people who plotted an armed hit on a caravan in Carmarthenshire have been found guilty of conspiracy to murder following a two-week trial.
Swansea Crown Court has heard how Michelle Mills and Geraint Berry planned to kill Christopher Mills so they could continue their affair.
A third person – Steven Thomas – who was alleged to have been recruited by Berry to assist with the conspiracy, was found not guilty of conspiracy to murder. He had previously admitted a charge of possessing a firearm with intent to cause Christopher Mills to believe that unlawful violence would be used against him or another person.
Dyfed-Powys Police received a 999 call shortly after 11.30pm on September 20, 2024, reporting that two masked men wielding guns had entered a caravan in Cenarth, Ceredigion, and assaulted Mr Mills.
Despite being badly beaten, the victim was able to fight the two men off, and the intruders fled the caravan.
Making the emergency call, Michelle Mills, aged 46, said her husband had sustained a head injury in the attack, and claimed the two men, who were dressed all in black with their faces covered, were unknown to her.
The court heard that Mills and Berry had intended to murder Mills’ husband and make it look like a suicide.
Mills was arrested and charged with conspiracy to murder her husband. On arrest, she told officers ‘I’m going to prison for this, aren’t I?’.
Berry and Thomas, of Clos Coffa in Clydach, faced the same charge, which all three denied.
After a two-week trial, Michelle Mills and Geraint Berry found guilty of conspiracy to murder by a jury.
Steven Thomas was found not guilty of the charge. He had previously pleaded guilty to possessing a firearm with intent to cause Christopher Mills to believe that unlawful violence would be used against him or another person.
DI Sam Gregory, from Dyfed-Powys Police, said: “I am pleased that Michelle Mills and Geraint Berry have now been found guilty of conspiracy to murder, and that they will be suitably sentenced for their part in their plans to kill Mr Mills.
“While this case has all the makings of a TV drama, at the heart of it was a very real conspiracy to take someone’s life, and there were potentially fatal consequences to the planned attack on September 20.
“Mills and Barry had plotted not one, not two, but three attempts to take Mr Mills’ life, and I have no doubt that they would have continued to come up with these plans had they not been caught that night.
“They will now face the consequences of their actions.
“I would like to thank all the officers and staff who worked on this investigation, and gathered strong evidence to secure these convictions, as well as Mr Mills for his integrity and cooperation throughout the criminal justice process.”
Michelle Mills, Geraint Berry and Steven Thomas will be sentenced on December 19.
