What Happened
A 21-year-old South Korean woman identified only by surname Kim used OpenAI's ChatGPT to research lethal drug-alcohol interactions before carrying out two murders in Seoul.
Kim, who had prescribed benzodiazepines, queried ChatGPT with progressively specific questions about the lethality of mixing sleeping pills with alcohol, including asking directly whether the combination 'could kill someone.'
The timeline of events:
- December 2025: Kim laced the drink of a man she was dating with sedatives in a parking lot. He lost consciousness but survived
- January 28, 2026: Kim accompanied a man in his twenties to a Gangbuk motel in Seoul. She spiked his drink with benzodiazepines. He was found dead the following day
- February 9, 2026: Kim repeated the same method at another Seoul motel. A second man was found dead
- February 11, 2026: Kim was arrested on a lesser charge of inflicting bodily injury resulting in death
Police discovered Kim's ChatGPT conversation history during their investigation, which established premeditated intent and led to charges being upgraded to murder.
AI Behaviors Exhibited
- ChatGPT provided information about the dangerous and potentially lethal effects of combining sleeping pills with alcohol
- Responded to escalating questions about drug lethality without adequate safety intervention
- Answered the direct question 'Could it kill someone?' regarding drug-alcohol combinations
How Harm Occurred
ChatGPT served as an accessible information source for researching lethal methods. The perpetrator used the chatbot to verify that her planned method of spiking drinks with benzodiazepines could be fatal, then carried out the plan against three victims (two of whom died). The AI's responses provided confirmation that her method would work, contributing to premeditated murders.
This is a case of third-party harm facilitation where the AI user was the perpetrator, not the victim.
Outcome
Ongoing- February 11, 2026: Kim arrested on initial charge of inflicting bodily injury resulting in death
- Charges subsequently upgraded to murder after police discovered ChatGPT conversation history establishing premeditated intent
- Kim had asked ChatGPT: 'What happens if you take sleeping pills with alcohol?', 'How much would be considered dangerous?', 'Could it be fatal?', and 'Could it kill someone?'
- She also had a prior attempted murder in December 2025 where a male victim survived after being drugged in a parking lot
