Overview of the Incident
Tristan Roberts, an 18-year-old from Prestatyn, Wales, has been sentenced to life imprisonment for the murder of his mother, Angela Shellis, a 45-year-old teaching assistant. The crime occurred on October 24, 2025, when Roberts bludgeoned his mother to death with a hammer, recording the attack on a dictaphone. He was sentenced to a minimum of 22 years and six months in prison at Mold Crown Court.
Details of the Crime
The attack was premeditated, with evidence showing that Roberts had expressed violent intentions online prior to the murder. He had a history of troubling behavior, including previous convictions for possessing a knife. On the night of the murder, he lured his mother from their home under the pretense of seeking medical help, forcing her to wear a balaclava. Surveillance footage captured them leaving their home at 3:19 AM, and shortly thereafter, Roberts attacked her at Coed y Morfa nature reserve.
During the attack, Roberts recorded himself, stating, “This is Tristan Roberts. Tonight I’m going to murder my mother with a sledgehammer.” The recording captured Angela's screams as she was struck multiple times. Following the murder, Roberts attempted to conceal the crime by dragging her body and disposing of evidence, including her crutch and a blood-soaked balaclava.
Background and Context
Roberts had a documented history of mental health issues, including autism and ADHD, which his mother had sought help for in the months leading up to the murder. Angela Shellis had expressed concerns about her son’s behavior, including messages to social workers about his possession of weapons. Despite her efforts to obtain support, the family struggled to find adequate resources.
Official Statements & Responses
Judge Rhys Rowlands, during sentencing, remarked on the calculated nature of Roberts' actions and noted that he appeared to revel in the control he exerted over his mother. He stated, “It was made all the more dreadful by the fact her attacker was her own son, someone who it is clear she both cared for and, indeed, worried about in the weeks leading up to her death.”
In a statement, Angela’s sister, Sarah Gunther, expressed the family's heartbreak and confusion, stating, “It is incredibly hard to express our feelings towards you now. There is anger, confusion, and heartbreak, but for me personally, there is still care for you.”

The case has raised concerns regarding the adequacy of mental health support for young individuals like Roberts. Critics have pointed to systemic failures in addressing the needs of families dealing with severe behavioral issues.
