Convicted Teen Killer Jay Stewart Reportedly Boasts About Murder From Prison Cell

The profanity-filled verses in the video contain numerous references to the killing of 'KM' or 'Kayden'. Stewart explicitly states, 'Everyone knows my scheme is violent, big plan for future ahead.'

A fellow inmate reportedly held the phone, laughing and whooping in the background as Stewart performed.

Paul Moy, Kayden's father, expressed profound devastation upon viewing the video. He stated, "Today my family was devastated by a leaked video from inside Polmont showing Jay Stewart convicted of killing my son singing, laughing, and appearing to boast about taking my son's life."

Moy added, "Nothing will ever prepare a parent for something like this." The family's ongoing suffering remains palpable.

He further articulated the family's ongoing pain, saying, "We live every day with the heartbreak of losing Kayden while the person responsible appears to show no remorse and no respect."

The Scottish Prison Service acknowledged the distress such videos cause. A spokesperson stated, "We understand the lasting impact this kind of offending has on families and the significant distress such videos can cause."

The spokesperson affirmed the service's commitment to security. They noted, "Our staff work hard to keep prisons safe and secure, using all available technology and intelligence to prevent illicit items, including mobile phones, entering our establishments."

They added, "While we do not comment on individuals, we continue to work with Police Scotland, and other partners, to take action against those who attempt to breach our security."

Police Scotland has initiated inquiries into the matter. A spokesperson confirmed, "Inquiries are ongoing following a report of an online communication offence from HM YOI Polmont on Tuesday July 28 2026."

This investigation follows a report of an online communication offence originating from HM YOI Polmont on Tuesday, July 28, 2026. The date marks a specific point of official action against the breach.

The alleged boasting from within the prison system starkly contrasts with the initial aftermath of the crime. Teenagers were filmed celebrating the attack after the fatal wound was inflicted, revealing a pattern of callous disregard.

Historically, the issue of illicit mobile phones in Scottish prisons has plagued authorities for years. Incidents involving social media posts from inside establishments, including HMP Barlinnie and HMP Shotts, have surfaced repeatedly since 2015, demonstrating a persistent security challenge.

Stakeholders, including victims' rights advocates and political figures, exert immense pressure on the Scottish Prison Service. Public outcry over such videos demands immediate and decisive action, impacting public trust in the justice system.

Economically, the cost of implementing advanced jamming technology and increasing staff to combat phone smuggling runs into millions of pounds annually. This financial burden diverts resources from other critical rehabilitation programs.

The landscape of prison security faces a future shaped by rapidly evolving technology. The proliferation of miniature devices and encrypted communication methods presents an escalating challenge for detection and prevention.

Societal shifts towards instant online sharing mean that even isolated incidents can quickly go viral, amplifying their impact. This digital reality forces prison services to adapt their security protocols at an unprecedented pace.

The future demands a multi-faceted approach, integrating cutting-edge technology with enhanced intelligence gathering and robust legal frameworks. Without such measures, the cycle of illicit communications and the distress they cause will continue.

This incident at Polmont highlights the ongoing struggle to maintain order and security within correctional facilities.
