Overview
- The defendants, Adina Mihai and Madalin Dumitru, changed pleas on Wednesday, June 24, 2026 and admitted two counts of manslaughter and multiple counts of administering the date‑rape chemical GBL.
- Prosecutors say the pair posed as an escort, took deposits, secretly spiked drinks with GBL to render men unconscious, and then stole property from victims’ homes.
- The prosecutions link two deaths by poisoning: Malcolm King, who died after an incident in August 2024, and Gary Mouat, who died in July 2025, plus two other men who survived but whose identities are subject to reporting restrictions.
- Thames Valley Police and Gloucestershire Constabulary say forensic evidence and a national police intelligence bulletin prompted the cross‑force inquiry that identified the pattern of attacks.
- Mrs Justice Brunner warned the pair they face substantial prison terms and remanded them in custody ahead of sentencing; police say they are keeping an open mind about further victims and encourage those affected to contact investigators.
