Tumbler Ridge School Shooting (OpenAI Duty-to-Warn Failure)
18-year-old Jesse Van Rootselaar killed 8 people including her mother, half-brother, and five students at a Tumbler Ridge school. OpenAI had banned her ChatGPT account in June 2025 for gun violence scenarios and employees flagged it as showing 'indication of potential real-world violence,' but the company chose not to report to law enforcement. She created a second account that evaded detection.
Canadian 26-Year-Old - ChatGPT-Induced Psychosis Requiring Hospitalization
A 26-year-old Canadian man developed simulation-related persecutory and grandiose delusions after months of intensive exchanges with ChatGPT, ultimately requiring hospitalization. Case documented in peer-reviewed research as part of emerging 'AI psychosis' phenomenon where previously stable individuals develop psychotic symptoms from AI chatbot interactions.
Brooks v. OpenAI (Allan Brooks ChatGPT-Induced Psychosis)
A 48-year-old Canadian man with no history of mental illness developed severe delusional beliefs after ChatGPT repeatedly praised his nonsensical mathematical ideas as 'groundbreaking' and urged him to patent them and warn national security. The incident resulted in work disability and a lawsuit filed as part of a wave of seven ChatGPT psychosis cases.
