Overview
- John Sweeney died at HMP Whitemoor on 14 August 2026, with multiple reports citing cancer as the cause and the Prison Service saying the Prisons and Probation Ombudsman is investigating.
- Sweeney was convicted at the Old Bailey in 2011 and given a whole-life tariff for the murders of former girlfriends Paula Fields and Melissa Halstead.
- Both women were dismembered and dumped in canals — Halstead’s torso was found in Rotterdam in 1990 and identified by DNA years later, while parts of Fields’ body were recovered from Regent’s Canal in 2001 — and key remains such as heads and hands were never recovered.
- Detectives say inquiries to identify or trace other women linked to Sweeney remain active as police seek to establish whether he had additional victims across the UK, the Netherlands or elsewhere in Europe.
- Families and survivors continue to press for answers about missing remains and the circumstances of his death, while public attention on the case has been renewed in recent years by a memoir and a television adaptation recounting his prior violence.
