Tristan Thomas Roberts, 18, of Coniston Drive, Prestatyn, murdered his mother Angela Shellis, 45, on October 24, 2025. He planned the attack for at least three weeks, purchasing hammers, knives, and protective clothing online, and researching murders. The attack began at their shared home around 11pm on October 23, 2025, where he strangled her while she was conscious and pleading for help, recording the assault. He then deceived her into wearing a balaclava and led her through a railway line to an isolated area at Prestatyn's Morfa nature reserve, where he bludgeoned her to death with a lump hammer, inflicting multiple blows to the head causing severe blunt force injuries. He dragged her body about 100 metres into undergrowth, returned home, and boasted about the murder on Discord using graphic language. Her body was discovered later that morning by a member of the public.

Defendant diagnosed with autism and ADHD, showed signs of emerging personality disorder, but no abnormality of functioning at the time of the crime.
