AI Incident Database: ChatGPT Was Reportedly Used in Planning School Stabbing in Pirkkala, Finland, That Injured Three Pupils

In May 2025, a 16-year-old boy stabbed three 14-year-old girls at Vähäjärvi School in Pirkkala, Finland. Same-day reporting said a manifesto attributed to the suspect claimed he used ChatGPT while planning the attack. Later court reporting said police found hundreds of pre-attack searches or queries described as involving AI, including topics related to stabbing, anatomy, school attacks, police procedures, evidence concealment, and manifestos.
