# Couple Jailed for 17 Years for Killing and Drugging Men for Theft

A couple has been sentenced to 17 years in prison for drugging men with a powerful sedative to steal from them, resulting in the deaths of two individuals. The pair admitted to manslaughter and administering poison, with a judge highlighting the extreme risks involved in their actions.

## Key takeaways

- Adina Mihai and Madalin Dumitru were sentenced to 17 years in prison for killing two men and poisoning others.
- The couple used a powerful sedative, GBL, to drug victims before stealing from them.
- Gary Mouat and Malcolm King died as a result of the drugging and theft.
- The court highlighted the defendants' disregard for the severe risks associated with administering GBL.

Adina Mihai and Madalin Dumitru have each received a 17-year prison sentence for manslaughter and administering poison. The couple drugged men they met for sexual services, intending to steal from them. Two men, Gary Mouat and Malcolm King, died as a result of being drugged with gamma-butyrolactone (GBL), a powerful sedative. Two other victims survived the attacks.

Mihai advertised sexual services online, arranging to meet clients at their homes. Dumitru would accompany her, waiting nearby, sometimes armed. The court heard that the pair would spike the victim's alcoholic drinks with GBL. Once the victims lost consciousness, Mihai would steal valuables such as cash, aftershave, and watches. Prosecutors stated the couple acted out of greed.

During sentencing at Oxford Crown Court, Mrs Justice Brunner KC described the GBL dosages as "haphazard" and noted that the defendants could have realised the high risk of serious injury or death with minimal consideration. The judge added that basic research would have revealed GBL's extreme toxicity.
