  • โ€ขSeoul's Gangbuk Police Station upgraded charges against 21-year-old suspect Kim from 'inflicting bodily injury resulting in death' to murder after forensic analysis of her phone revealed repeated ChatGPT queries on mixing sleeping pills (benzodiazepines) with alcohol, such as 'What happens if you take sleeping pills with alcohol?' and 'How much is dangerous?'[1][2][3]
  • โ€ขKim allegedly poisoned three men in their 20s: a non-fatal attempt on her then-partner in a Namyangju cafe parking lot in December 2025, causing coma; fatal poisoning of one man on January 28, 2026, in a Suyu-dong motel; and another on February 9, 2026, in a Gangbuk motel, with the first victim surviving after regaining consciousness[1][2][3][4]
  • โ€ขAfter the first surviving victim awoke, Kim doubled the drug dosage in subsequent attempts and ignored ChatGPT warnings about lethality, demonstrating awareness of fatal risks, which police used to prove premeditated intent[1][2][5][6]
  • โ€ขSuspect claimed during interrogation she only intended to make victims sleep after disagreements and mixed her prescribed mental health medication into drinks without expecting death, but evidence including increased doses and ChatGPT searches contradicted this[1][3][6]
  • โ€ขPolice conducted psychological profiling and profiler interviews on Kim, with results pending for prosecutors; they are investigating potential additional victims and noted her efforts to conceal evidence, like removing drug bottles[1][5]

This case marks one of the first instances where AI chatbot query history has been pivotal in proving criminal intent in a murder investigation, potentially setting precedents for digital forensics in courts worldwide and raising debates on user data retention by AI providers for law enforcement.
