British Columbia filed a lawsuit in California against OpenAI and CEO Sam Altman for negligence. The province alleges the company’s failure to report alarming ChatGPT activity contributed to a mass shooting in Tumbler Ridge.

The shooter used the AI platform to plan an attack that killed nine people. Six children were among the victims of the deadly incident.

The lawsuit claims OpenAI leadership overruled internal safety recommendations to alert law enforcement. Plaintiffs argue the company designed an unsafe product and seek damages alongside mandatory protocol changes.

This legal action follows dozens of similar lawsuits from survivors and victims' families.
