Who Is Kim So-young, the 'Most Beautiful Killer'? Why Are South Korean Prosecuters Seeking Death Penalty for Her?
South Korean prosecutors have requested the death penalty for 20-year-old Kim So-young, accused of murdering two men by spiking their drinks with psychiatric drugs at motels. Cited for premeditation and lack of remorse, Kim faces a final verdict on August 27. Her defence claims the acts were defensive, a narrative rejected by victims' families and authorities.
South Korean prosecutors have demanded the death penalty for 20-year-old Kim So-young, the defendant in a high-profile series of motel poisoning and murder cases. Kim is accused of killing two men and injuring four others by giving them laced drinks. During the final sentencing hearing at the Seoul Northern District Court, authorities cited the extremely heinous nature of the crimes, premeditated actions, and a complete lack of remorse as the primary reasons for seeking capital punishment.
Who Is Kim So-Young?
Kim So-young is a 20-year-old South Korean woman who became the centre of public attention following her arrest and subsequent identity disclosure, reports The Korea Herald. Arrested and indicted earlier in the year, she was accused of targeting men in their 20s by luring them to motels in northern Seoul and other districts.

Investigators revealed that Kim systematically administered drinks laced with benzodiazepine-based psychiatric drugs - often hidden inside hangover relief beverages - to incapacitate her victims. While social media and local media commentary frequently sensationalised her appearance with monikers like the "most beautiful killer", criminal psychologists and law enforcement noted her chilling premeditation, scoring high on psychopathy assessments.
The Charges and Investigation
The case spans multiple incidents investigated between late 2025 and early 2026. Prosecutors state that Kim targeted multiple men, resulting in the deaths of two victims and severe medical complications, including toxic encephalopathy, for several others. Digital forensic evidence played a critical role in establishing premeditation. Investigators recovered search history from Kim's mobile device showing multiple queries made to generative AI services regarding the lethal limits of combining sleeping pills with alcohol. Police also discovered that she attempted to construct false alibis by messaging unconscious victims via KakaoTalk after administering the drugs.
Defence Arguments and Final Statements
During the trial proceedings, Kim's defence team argued for an acquittal, claiming there was insufficient direct evidence linking her administration of the drugs to the deaths and asserting there was no risk of recidivism. In her final statement to the court, Kim expressed remorse for administering substances out of fear of unwanted sexual advances, but maintained she had no intent to kill or seriously harm the victims. v
Legal representatives for the bereaved families strongly rejected these claims, calling the defence's narrative regarding sexual assault allegations an insulting attempt at secondary victimisation. The court is scheduled to deliver its final verdict and sentence on August 27.
