A 21-year-old woman in South Korea has been charged with the murders of two men, after investigators discovered she had repeatedly asked ChatGPT about the dangers of mixing drugs with alcohol.

Police in Seoul say that through analysis of her mobile phone they found that the suspect, identified only by her surname Kim, had asked ChatGPT "What happens if you take sleeping pills with alcohol?", "How many do you need to take for it to be dangerous?", and "Could it kill someone?"

Kim previously told police that she did mix prescribed sedatives containing benzodiazepines into the drinks but did not know the men would die.

However a police investigator said she was "fully aware that consuming alcohol together with drugs could result in death."

Kim was initially arrested on 11 February on the lesser charge of inflicting bodily injury resulting in death after two men died and another was left unconscious after going to a motel with her.
