South Korea lady serial killer becomes social media star after killing two men, leaving one in coma

A 20-year-old woman from South Korea, identified by her surname Kim, has become the focus of intense public and media attention after her she allegedly killed two men by putting sleeping pills in their drinks and leaving one in a coma.

Meanwhile, Kim has become a social media star in South Korea because of her looks. It is hard to believe that the beautiful woman is a ‘serial killer’.  Police detained Kim on Feb 19 and charged her with murder, causing bodily injury, and violating narcotics laws after investigating a string of incidents in and around Seoul’s Gangbuk District.

Giving Sleeping Pills

Authorities say she allegedly spiked the drinks of three men on three different occasions, leading to the death of two men, while another survived.

The first known incident happened in December 2025, when Kim allegedly gave a drug-laced hangover drink to a man in Namyangju, causing him to lose consciousness but later recover in the hospital.

Kim Denies Killing Victims

Following this, evidence suggests she increased the potency of the sedative mixture after the first victim survived. Later, two subsequent alleged attacks occurred at motels in Seoul’s Suyu-dong area on Jan. 28 and Feb. 9, where the victims consumed similar drinks and died due to the increased potency of the sedative mixtures.

Investigators say Kim utilized social media to lure victims. However, Kim has denied intending to kill her victims, asserting that her aim was merely to put them to sleep. However, law enforcement and forensic experts contend her behaviour, including upping the dosage after an initial failure and not seeking help for victims, indicates a more deliberate pattern.

Prosecutors have since upgraded the charges to murder and are investigating whether additional victims may exist.
