Responded
Description: Before an October 2024 knife attack in Zürich-Oerlikon, Switzerland, a 23-year-old student reportedly used ChatGPT to ask about consequences of killing random stabbing victims, where and when to find children, and human anatomy. He later stabbed three five-year-old boys, seriously injuring them. Prosecutors charged him with attempted murder; the allegations about his AI-assisted planning come from the indictment.
