A murder trial at the High Court in Glasgow has revealed new details about the fatal stabbing of 16-year-old Kayden Moy, who died from a 19-centimeter knife wound to his body. Pathologist Gillian Wilson, who conducted the post-mortem examination, testified about the severity of the injuries, which also included a non-fatal wound to his thigh.

Kayden Moy was killed on May 17, 2025, at Irvine beach. The court is hearing the case against two defendants: a 15-year-old boy and Jay Stewart, 18, both charged with Moy’s murder. Another defendant, Cole Turley, 18, entered a guilty plea prior to the commencement of the trial.

Prosecutors allege that Stewart and the 15-year-old held previous animosity against Moy, whose social affiliations were also scrutinized during proceedings. Testimony and evidence presented link the accused to gang rivalries; Turley, Stewart, and the 15-year-old are reported members of The Murray Boys gang based in East Kilbride, while Moy and his friends were associated with the rival Himshie gang.

The court heard from the 15-year-old defendant, who initially gave a police statement as a witness rather than a suspect. According to notes read to the jury, he denied any involvement in a feud with Moy and claimed no knowledge of conflicts between Turley and Stewart. He maintained he did not witness the stabbing or observe any weapons being brandished or used during the incident.

Forensic evidence introduced includes fingerprints linking the accused to items recovered from the scene and nearby locations. Catherine Boyle, a senior fingerprint examiner, testified that Turley’s print was identified on a lock-back knife found by police, while Stewart’s fingerprint was detected on a baton recovered during the investigation. The 15-year-old’s print was located on a window frame at the residence of Fraser Wallace, 19, who testified that the group had visited his home on the night of the stabbing but left before police arrived.

The trial is set to resume on Monday as the court continues to evaluate witness testimonies and forensic evidence in the case.
