Woman who posed as sex worker to drug men admits manslaughter

Woman who posed as sex worker to drug men admits manslaughter Adina Mihai and Madalin Dumitru, both formerly of Ilford, Essex, were arrested on July 31 last year - Bookmark A woman who posed as a sex worker and drugged men unconscious to steal from them has pleaded guilty to the manslaughter of two men. Adina Mihai, 31, and Madalin Dumitru, 30, arranged to meet men seeking sexual services at their homes and drugged them with gamma-butyrolactone (GBL) in order to steal from them between August 2024 and July 2025. Mihai and male defendant Dumitru took financial deposits from the victims before Mihai met them at their homes, Thames Valley Police said. The pair pleaded guilty at Oxford Crown Court on Wednesday via video-link to the manslaughter of Malcolm King, 80, in Bagendon, Gloucestershire, on August 20 2024 and Gary Mouat, 37, in Banbury, Oxfordshire, on July 12 2025. They also pleaded guilty to unlawfully and maliciously administering poison in the form of GBL to a man on July 13 2025 and another man on July 22 2025 – both men’s identities are protected by a reporting restriction. The court heard that the pair committed the offences following an agreement to “render the individuals unconscious in order to steal property from them” by secretly spiking their drinks with GBL – a substance that converts into GHB when in the body. Thames Valley Police said once detectives discovered Mihai had poisoned Mr Mouat, the force issued a national bulletin to all other police forces to share the intelligence in case any other unexplained deaths in the country were linked. Forensic links led to Gloucestershire Constabulary discovering Mr King had also been poisoned, after initially believing his death was not suspicious because of a pre-existing health condition. Mihai and Dumitru, both formerly of Ilford, Essex, were arrested on July 31 last year and their guilty pleas meant a trial, due to open on Wednesday, will not take place. Mrs Justice Brunner KC told the pair she would be passing “substantial sentences of imprisonment” on them. The judge added that she would sentence the pair at “some point in late July or early August” at Oxford Crown Court and remanded them in custody. Police said “no other deaths, poisonings or thefts have been linked to the investigation, at this time” but they are “keeping an open mind about the possibility of other victims”. Prosecutor Julian Evans KC told the court: “The offences were committed pursuant to an agreement between the defendants to render the individuals unconscious in order to steal property from them should such property be identified within their respective addresses. “The pleas are acceptable to the prosecution as a means of resolving the indictment in this case.” Mr Evans said the decision to accept the manslaughter pleas followed “contact with families of the deceased men” and consultation with “police forces who have investigated these matters over the course of many, many months”. Thames Valley Police senior investigating officer Detective Inspector Michael Roddy said it had been an “extremely complex and resource‑intensive investigation”. The police officer added: “Adina Mihai and Madalin Dumitru used drugs to incapacitate men who had been seeking sexual services, before stealing from them. “For Gary Mouat, these actions had fatal consequences so I am pleased to have got answers for his family and would like to thank them for their support throughout our investigation.” Gloucestershire Constabulary’s senior investigating officer, Detective Inspector Adam Stacey, said: “Tragically for Mr King, Mihai and Dumitru’s callous and calculated actions had fatal consequences. “The tireless work of all those involved in the joint investigation left Mihai and Dumitru with little choice but to plead guilty to manslaughter and administering poison in the face of overwhelming evidence.”
