In 2019, the Offender Database recorded that 74-year-old John McKno died in custody while serving a 14-year sentence for a campaign of non-recent child sexual abuse. Following an inquest at Norfolk Coroner’s Court, it was reported that the former maths teacher died at HMP Norwich on 29 September 2019. The cause of death was established as cardiac failure after choking on food. McKno, formerly of Alby in Norfolk, had been jailed in 2016 after admitting to a series of gross indecency, indecent assault, and serious sexual assaults against five pupils.
The investigation established that McKno used his position as a teacher to target vulnerable boys at boarding schools across Suffolk, Devon, and Worcestershire during the 1970s and 1980s. Suffolk Police and Devon and Cornwall Police reported that his offences took place at Beam College in Great Torrington, St Michael’s College in Tenbury Wells, and Kesgrave Hall School near Ipswich. The prosecution reported that four of his victims were boys under the age of 16, while one was a boy under the age of 14.
Judicial Findings and Investigative Detail
The court reported that McKno’s abuse had a devastating and long-lasting impact on his survivors, some of whom carried the trauma for over 40 years. Ipswich Crown Court heard harrowing testimony from victims, including one pupil at Kesgrave Hall who recalled sleeping with one eye open due to the fear McKno instilled. The investigation established that the defendant had been a trusted member of the teaching staff at several prestigious institutions, a status he exploited to isolate and abuse his victims.
Judge Martyn Levett presided over the 2016 sentencing, where he handed McKno a 14-year custodial term, noting that the defendant had finally been held accountable for decades of predatory behavior. For his actions in Suffolk, Devon, and Worcestershire, McKno was required to serve a significant portion of his life behind bars. The 2019 inquest confirmed that while his death was accidental, it occurred while he was a category 1 high-risk offender within the prison system.

Monitoring and Public Protection
Prior to his death, McKno was managed as a high-risk Category 1 predator within the national prison estate. Due to the nature of his conduct, which involved the systemic abuse of children in a residential school environment and a total breach of professional trust, his management was a maximum priority for the Multi-Agency Public Protection Arrangements (MAPPA). Authorities state that his history of targeting multiple young boys across three different counties required the highest level of institutional monitoring.
As a registered sex offender until his death, McKno’s details were permanently logged on the national police database. Authorities state that his behavior demonstrated a predatory focus on young boys that spanned his entire teaching career. While the legal proceedings concluded with his death in 2019, the police continue to offer support to any survivors of historic abuse at the institutions where he worked. Any further information regarding his conduct in Suffolk, Devon, or Worcestershire remains an interest to the public protection units in those areas.
