The families of victims of a school shooting in a Canadian Rockies town are suing artificial intelligence company OpenAI in U.S. federal court, seeking to hold the ChatGPT maker responsible for failing to alert police to the shooter’s alarming interactions with the chatbot.

A lawsuit filed Wednesday on behalf of 12-year-old Maya Gebala, who was critically injured in the February shooting, is among the first of dozens of cases that families in Tumbler Ridge, British Columbia are planning with claims alleging wrongful death, negligence and product liability.
