TikTok's operator said the voice was a generic male voice that the poster said came from AI trained on a friend's voice. The poster deleted the account in May 2026.

The AI system communicated with the user whose planned attack injured the children; that is why communicated_with is recorded although the children themselves did not use the system. No source quotes the prompts or ChatGPT's replies, so nothing is recorded about what the model answered or whether it refused or warned. The court attributed the planning and the attack to the accused; this record makes no causal claim about the model.","status":"supported"},"person_relations":["communicated_with"]},"name":"Zurich-Oerlikon, Switzerland: a student who researched killing methods, anatomy and where to find children with ChatGPT stabbed three five-year-olds walking to their daycare; sentenced on 18 September 2026 to 15 years for multiple attempted murder","summary":"At midday on 1 October 2024 a Chinese master's student, then 23, attacked a group of five-year-old kindergarten children walking with a daycare worker to their after-school Hort near Berninaplatz in Zurich-Oerlikon with a kitchen knife. Two boys suffered life-threatening neck and chest wounds (one had the jugular vein severed, one the pericardium and aorta cut); a third was wounded in the ear and the shoulder or lung. The daycare worker held the attacker's arms until he dropped the knife. The indictment and the court's oral reasoning, as reported by NZZ, Keystone-SDA/ATS and CH Media, describe weeks of preparation from summer 2024: he discussed ways of killing and their legal consequences with ChatGPT, studied anatomy, bought raw beef to practise stabbing, and used ChatGPT to find out where and when children could be encountered in Zurich. No source quotes the prompts or ChatGPT's replies. On 18 September 2026 the Zurich District Court convicted him of multiple attempted murder and imposed 15 years' imprisonment, treatment during custody, a 15-year expulsion from Switzerland and CHF 106,000 in moral damages to the three boys; it accepted that he was psychotic but found diminished, not absent, criminal responsibility. His lawyer announced an appeal. The parents of one boy described nightmares, self-blame and scars 23 months on.","incidentDate":"2024-10-01","incidentKind":"single_event","incidentDatePrecision":"day","exposurePattern":"repeated_interactions","reportedDate":"2024-10-02","aiSystem":"ChatGPT (OpenAI)","aiProduct":"ChatGPT","aiCompany":"OpenAI","severity":"high","verificationStatus":"credible","harmCategories":[],"harmOutcomes":["physical_injury","hospitalization","psychological_distress","harm_to_others"],"harmOutcomeSummary":"Three five-year-old boys were stabbed, two with life-threatening wounds requiring emergency surgery; one boy's parents describe persistent nightmares, self-blame and visible scars nearly two years later.
