A 24-year-old from Caernarfon has been sentenced to five years and seven months in prison for a sustained assault in which he bludgeoned his younger brother with a modified gun, continued attacking him after believing he had killed him, and then turned the weapon on others who tried to step in.
Jamie Williams, of Chapel Street, Caernarfon, appeared at Mold Crown Court where he admitted assault occasioning actual bodily harm, possession of a firearm with intent and without a certificate, possession of ammunition without a certificate, converting an imitation firearm into a useable firearm, and possession of cannabis. The offences all took place on April 18, 2026.
The attack
Prosecutor Emmalyne Downing told the court that Williams and his younger brother had been at the home of the younger brother’s girlfriend on the evening of April 17, 2026. An older brother was also present.
Drunken playfighting between Williams and his younger sibling spiralled into violence. Williams struck his brother with a flurry of punches to the face as the victim struggled to defend himself. When the younger brother tried to walk away, Williams pulled a gun from his waistband – an imitation firearm that had been converted to fire live rounds – and hit him on the head with its handle.
The blow sent the victim to the floor unconscious. Williams then punched him repeatedly and stamped on his head while he lay motionless.
Ms Downing said Williams was described as being “out of control.” On more than one occasion he told those present that he believed he had killed his brother – yet continued the assault regardless.
The victim suffered a swollen face and two black eyes.
The threats
Williams refused to leave when asked. When his younger brother’s girlfriend and the older brother attempted to intervene, he pointed the gun directly at them and threatened to kill them if they contacted police.
He brandished the weapon for an estimated five minutes and at one point was seen trying to load a bullet into it.
The firearms
An ambulance was called for the victim. Police later attended at Williams’ grandmother’s home, where a search uncovered several items hidden beneath the floorboards. These included the converted imitation firearm – confirmed to be useable – two further firearms that were not dangerous, and a box of ammunition.
Sentencing
The court heard Williams had 13 previous convictions for 27 offences, including eight for violence.
Duncan Bould, defending, said his client had entered an early guilty plea and had endured a “chaotic” upbringing, spending considerable time in the care system. He told the court there was no evidence the gun had been used elsewhere. Williams suffered from mental health difficulties and was hoping to learn bricklaying during his sentence, Mr Bould added.
Judge Nicola Jones told Williams: “You carried out a vicious and sustained attack on your brother. You were relentless.”
She noted that he had held the firearm “one foot away from the face” of his younger brother’s girlfriend.
Williams was sentenced to five years and seven months in prison. He will serve half the term in custody, with the remainder on licence. A forfeiture order was made for the destruction of the gun, ammunition, and cannabis, and he must also pay a statutory surcharge.
