Tristan Roberts

Tristan Roberts lived in Prestatyn, Denbighshire, Wales, and resided on Coniston Drive with his mother, Angela Shellis, at the time of the offence.

Little verified information has been publicly released regarding his childhood, education, or employment. Public reporting has focused primarily on the homicide investigation and subsequent court proceedings.

Before the murder, Roberts had no comparable nationally reported criminal profile.

In October 2025, Roberts murdered his mother, Angela Shellis.

The killing occurred at Coed y Morfa nature reserve near Prestatyn, where investigators later established that Angela had been fatally attacked. Following the murder, Roberts attempted to conceal aspects of the crime before police launched an extensive investigation into her disappearance.

Detectives gathered forensic evidence and reconstructed Roberts' movements, ultimately identifying him as the person responsible for Angela Shellis' death.

Investigators determined that Roberts acted alone in murdering his mother.

The prosecution relied upon forensic evidence, witness testimony, digital evidence, and Roberts' actions following the killing to demonstrate his responsibility. The investigation also examined efforts made after the murder to conceal the offence.

The evidence presented at trial established Roberts' involvement beyond reasonable doubt.

Following Angela Shellis' disappearance, North Wales Police launched a major investigation involving searches, forensic examinations, and witness interviews.

As evidence accumulated, detectives arrested Tristan Roberts and charged him with murder.

The investigation continued through to trial, with prosecutors presenting extensive forensic and circumstantial evidence linking Roberts to the crime.

Tristan Roberts stood trial at Mold Crown Court.

On 25 March 2026, he was convicted of the murder of Angela Shellis.

The court sentenced Roberts to life imprisonment with a minimum term before he becomes eligible to apply for parole.

He remains incarcerated within the prison system serving his life sentence.

The murder of Angela Shellis had a profound impact on her family and the local community in North Wales.

The investigation highlighted the extensive work undertaken by North Wales Police, forensic specialists, and prosecutors in reconstructing the events leading to Angela's death and securing Roberts' conviction.

The case remains one of the most significant homicide investigations in North Wales during 2025.
