The chilling footage captured a teenager leading his mother across a desolate landscape, unaware of the horrific fate that awaited her. Tristan Roberts, just 17 years old, walked alongside Angela Shellis in the pre-dawn darkness, a sinister calm masking the violence he was about to unleash.
Roberts hadn't simply snapped. Months before the brutal attack, he’d been meticulously planning his mother’s murder. Online searches revealed a disturbing obsession with methods of killing, weapon usage, and the chilling details of concealing a crime – erasing blood, DNA, and even a body.
The recording from that night is harrowing. Roberts, adopting a bizarre American accent, asked his mother to sit on a bench in Coed y Morfa nature reserve. Then came the screams, quickly followed by the sickening thud of a hammer connecting with bone – at least four devastating blows.
Before the violence, Roberts had broadcast his hatred online, posting disturbing messages on Discord. He expressed a deep-seated animosity towards women, claiming abandonment and betrayal, and openly declared his intent to kill his mother for “revenge, justice and vengeance.” He cycled through numerous online aliases, constantly blocked for the disturbing nature of his posts.
After the attack, a chilling detachment settled over Roberts. He recorded himself, breathlessly stating, “Oh God that was terrifying… That felt so crazy.” He then casually messaged friends, detailing the brutality with horrifying clarity – “beat the s* out of her,” and “smashed her skull in so hard with a sledge hammer.”
Angela Shellis’ body was discovered later that morning, hidden in the undergrowth. The discovery shattered her family, leaving her son Ethan in tears during the court proceedings. He simply stated, “All my mum ever did was love Tristan.”
In a poignant impact statement, Angela’s sister, Sarah Gunther, expressed a complex mix of emotions. “There is anger, confusion and heartbreak,” she said, yet remarkably, she still held a flicker of care for her nephew. “For me personally, there is still care for you.”
The court learned that Angela had tirelessly sought help for Tristan, who had been diagnosed with autism and ADHD. She fought for her son, a fiercely supportive mother who never gave up, even when life presented insurmountable challenges. Her love, her family said, was unbreakable.
Detective Superintendent Andrew Gibson, speaking after Roberts’ life sentence with a minimum of 22 years, commended Angela’s bravery. He noted she remained calm and continued to show her love for Tristan even during what must have been a terrifying ordeal. Her unwavering devotion, even in the face of unimaginable horror, is a testament to the enduring power of a mother’s love.
Her sister’s tribute painted a picture of a woman who devoted herself to her sons. She was a fantastic mother, fiercely supportive, and a source of strength for her family. The loss leaves a void that can never truly be filled.
