South Korea: A 20-year-old beauty uses ChatGPT to plan a series of murders—Instagram followers surge 50x! Confession of remorse exposed

South Korea has recently been shaken by the shocking “Gangbuk-gu car motel serial murder case,” and 20-year-old Kim So-young has been charged with attacking multiple men by putting drugs into their drinks, resulting in 2 deaths and 4 injuries. As the case moves into the trial stage, the suspect, Kim So-young, submitted an apology letter before the hearing. The details of the case and the motive for the crime continue to draw public attention. The public is also paying attention to the fact that, during the course of the crime, the suspect is suspected of having searched for and planned related information using AI tools such as ChatGPT.

South Korea’s beauty plans the Gangbuk car motel serial killing case using ChatGPT

The case can be traced back to December 2025. At the time, Kim So-young first attacked her then-boyfriend, added a benzodiazepine-class drug to his drink, causing him to lose consciousness and be taken to the hospital, where he ultimately recovered. Crime experts believe that this was very likely her “test” before committing the series of murders.

After that, using the same method, Kim So-young carried out attacks in succession at car motels around the Gangbuk-gu area of Seoul against two men in their 20s, ultimately resulting in the deaths of both. Police investigations show that after her first “test,” she had already grasped the drug’s effects and duration of action, and in subsequent crimes she increased the dosage, making the outcome far more lethal.

It is worth noting that after police obtained Kim So-young’s phone, they found that in the process of planning the case and learning about drug dosages, she relied heavily on AI tools such as ChatGPT. Even more astonishingly, the case ended up drawing public attention to the woman’s striking appearance. After the case details were revealed, her IG following surged by 50 times.

Kim So-young was arrested in February of this year near her residence, and in the same month on the 19th she was transferred to prosecutors, who detained and indicted her. Prosecutors, through the adjudication process, have publicly released her name, age, and appearance information. Before the first hearing, on April 1, Kim So-young submitted an apology letter to the court. Although the contents have not yet been made public, outside speculation suggests that she may continue her claims from the investigative stage, denying that her crime involved intent to kill, and trying to reduce the charge from “murder” to “causing death” in order to seek a lighter sentence.

However, because this case involves multiple victims, the criminal method is highly planned, and no meaningful compensation has been made yet, legal circles generally believe that the apology letter will have limited impact on sentencing. During future proceedings, whether she had intent to kill will become a key focus of contention.

In addition, a prior assessment of psychopathy (PCL-R) conducted by police showed that Kim So-young scored 25 out of a possible 40 points, classifying her as psychopathic. The prosecution has also characterized this case as an “abnormal-motive crime” and a “premeditated, planned crime.”
