Overview

• Peniston was convicted last year of murdering 16-year-old Kennie Carter in Stretford and received the youth equivalent of a life sentence with a minimum term of 17 years after a jury rejected his self‑defence claim.
• The killing was described in court as a revenge attack the day after an altercation, with CCTV showing Peniston minutes later miming the stabbing to others.
• Media could not identify him during proceedings; a bid to lift restrictions after conviction was refused, but publication became lawful once he turned 18.
• Three other teenagers were convicted of manslaughter, with Latif Ferguson sentenced to five years’ detention and two others to four years, while six defendants were cleared.
• Court material disclosed an escalating history of knife offending from age 13, including a 2022 violent disorder involving a machete and a 2023 machete wounding in Leeds, alongside findings of childhood trauma and a referral indicating reasonable grounds for criminal exploitation.
