Overview of the Crime
On October 25, 2025, 45-year-old Angela Shellis was brutally murdered by her 18-year-old son, Tristan Roberts, in a premeditated attack fueled by his violent obsessions and misogynistic beliefs. Roberts, who had been planning the murder for weeks, used weapons he purchased online, including hammers and knives, to carry out the crime. He recorded the attack on a Dictaphone, detailing his intentions and the violence inflicted upon his mother.
Details of the Attack
Roberts lured Shellis from their home in Prestatyn, Denbighshire, under the pretense of seeking medical help. Surveillance footage captured the pair walking to Morfa Nature Reserve, where Roberts attacked her, striking her multiple times with a hammer. The attack lasted several hours, during which Shellis pleaded for her life. After the murder, Roberts attempted to conceal the crime by cleaning the scene and misled family members about her whereabouts.
Background and Context
Tristan Roberts had a history of behavioral issues, including diagnoses of autism and ADHD. His mental health deteriorated after moving in with his mother in 2021, and he exhibited increasingly violent tendencies. Angela Shellis had sought help for her son, expressing concerns for her safety in the weeks leading up to the murder. Despite her efforts, Roberts' violent fantasies, which included a fascination with serial killers, escalated unchecked.
Official Statements & Responses
During the sentencing at Mold Crown Court, Judge Rhys Rowlands emphasized the severity of the crime, stating, "You not only ended your mother’s life - you caused dreadful anguish to the whole family." He noted that medical experts found Roberts was aware of his actions and capable of self-control at the time of the murder. Angela's sister, Sarah Gunther, expressed her heartbreak, stating, "The impact of your actions in taking Angela from us all is something we now have to live with every single day."
Sentencing and Legal Proceedings
Tristan Roberts pleaded guilty to murder and was sentenced to life imprisonment with a minimum term of 22 years and six months. The court heard that he had previously been flagged for abusive behavior on social media platforms, including Discord, where he had multiple accounts and had been banned for violating community guidelines. His online activities included posting graphic content about violence and expressing hatred towards women.
Criticism & Opposition
The case has raised questions about the adequacy of mental health support for individuals like Roberts, as well as the responsibilities of social services in addressing the concerns raised by Shellis. Denbighshire County Council stated that the case has been referred to the North Wales Safeguarding Board, but declined to comment further on the support provided to Shellis.
Conclusion
The tragic murder of Angela Shellis by her son Tristan Roberts highlights the complexities of mental health issues, familial relationships, and the potential for violence when such issues are inadequately addressed. The case serves as a somber reminder of the devastating impact of unchecked mental health problems and the importance of timely intervention.
