Woman Who Pretended to Be a Sex Worker and Drugged Men Admits Manslaughter of Two Victims
Crime and Consequence: A Dangerous Scheme Unveiled
Woman who posed as sex worker – In a case that has shaken local communities, a woman who orchestrated a deadly scheme involving sedation and theft has entered a guilty plea for the deaths of two men. Adina Mihai, 30, and her partner Madalin Dumitru, 29, admitted to causing the deaths of Malcolm King, 80, and Gary Mouat, 37, through the administration of a potent drug known as gamma-butyrolactone (GBL). The pair targeted individuals seeking sexual services, luring them into their homes under false pretenses before incapacitating them with the substance.
Malcolm King was found dead at his residence in Bagendon, near Cirencester, in August 2024, while Gary Mouat succumbed to his injuries in July 2025. The timeline of events revealed a pattern of calculated crime spanning over a year. According to Thames Valley Police, the duo met victims in their homes, where they would administer GBL to render them unconscious, enabling the theft of valuables and personal belongings.
Before executing the plan, Mihai and Dumitru would collect financial deposits from their victims. This step ensured they had access to the homes, allowing them to exploit the situation. The police confirmed that the pair had previously planned to “render individuals unconscious to facilitate the theft of property,” as outlined in their confession. The drug, GBL, is known to convert into gamma-hydroxybutyric acid (GHB) in the body, which can lead to severe sedation or even coma.
Discovery of the Crime: A National Investigation Unfolds
The case took a tragic turn when investigators uncovered a link between the deaths of King and Mouat. Initially, King’s death was attributed to a pre-existing health condition, but forensic analysis later revealed poisoning. Thames Valley Police had issued a national alert after identifying that Mihai had administered GBL to Mouat on 12 July last year, prompting other forces to scrutinize similar incidents.
“Once we established that Adina Mihai had poisoned Mr. Mouat, we knew we had to act quickly,” said Detective Inspector Michael Roddy, the lead investigator. “This alert helped us connect the dots and uncover the second victim, Malcolm King.” The police force emphasized the complexity of the investigation, which involved cross-referencing evidence across multiple jurisdictions and analyzing the effects of GBL on the victims’ systems.
During the trial at Oxford Crown Court, the prosecution presented evidence showing the pair’s premeditated approach. They had targeted men seeking sexual services, luring them with the promise of intimacy before drugging them. The court heard that the duo’s actions were not only reckless but also deliberate, as they aimed to steal from their victims without resistance.
Guilty Pleas and Legal Implications
Despite initially denying 19 charges, Mihai and Dumitru eventually accepted responsibility for their crimes. Their guilty pleas included two counts of manslaughter and two charges of administering poison with the intent to injure, agrieve, or annoy. This admission came during the first day of their trial, which had been postponed due to the complexity of the case.
“The pleas are acceptable to the prosecution as a means of resolving the indictment,” stated Julian Evans KC, the prosecutor. “This case demonstrates how a single scheme can lead to multiple fatalities, and the defendants’ actions have had devastating consequences.” Evans highlighted the meticulous planning involved, noting that the pair had devised a method to exploit the trust of their victims while ensuring their own safety.
Thames Valley Police described the investigation as “extremely complex and resource-intensive.” The process required linking forensic evidence to the victims’ medical records, confirming that the drug had played a critical role in their deaths. “Adina Mihai and Madalin Dumitru used drugs to incapacitate men seeking sexual services, before stealing from them,” said Roddy. “For Gary Mouat, these actions had fatal consequences, and we are grateful to his family for their support throughout this ordeal.”
Gloucestershire Constabulary’s senior investigating officer, Detective Inspector Adam Stacey, added: “Tragically, Mr. King’s death was a direct result of the pair’s callous and calculated actions. The joint effort of all involved in this case led to the discovery of the link between the two deaths, and we are pleased that the defendants have taken responsibility.”
While the current investigation has not linked other deaths or incidents to the case, authorities remain vigilant. “We are keeping an open mind about the possibility of additional victims,” said Stacey. “This case serves as a reminder of the dangers posed by individuals who exploit trust for personal gain.”
Impact and Future Steps
The case has sparked discussions about the risks associated with GBL and the need for increased awareness among the public. Police officers emphasized that the drug’s effects can be unpredictable, especially when combined with other substances. “This case underscores the importance of checking for signs of poisoning, particularly in individuals who appear to be in a vulnerable state,” said a spokesperson for Thames Valley Police.
As the legal proceedings continue, the focus remains on the pair’s actions and their consequences. The guilty pleas mark a significant step in the case, but the trial will now delve into the details of their motivations and the extent of their involvement. With the potential for more victims still under investigation, the case is far from closed, though the defendants have taken responsibility for the lives they took.
“The victims’ families have been through immense emotional turmoil,” said Evans. “Their support was crucial in bringing this case to light, and we hope the guilty verdicts provide some measure of justice.” The trial will now proceed to determine the appropriate sentencing for Mihai and Dumitru, with the possibility of further charges if additional evidence emerges.
“The tireless work of all those involved in the joint investigation left Mihai and Dumitru with little choice but to plead guilty,” said Stacey. “We are committed to ensuring that justice is served for both victims and their families.”
With the guilty pleas accepted, the next phase of the trial will address the severity of the crimes and the defendants’ intent. The case has highlighted the dangers of premeditated crime and the need for vigilance in identifying potential threats. As the court continues its work, the public is reminded of the importance of staying alert and informed about the risks of drug-facilitated offenses.
