Stacey v. Altman (Tumbler Ridge failure-to-warn cluster)

The original seven related suits by families of the Tumbler Ridge mass-shooting victims allege that OpenAI's systems flagged the shooter's gun-violence planning, that safety staff urged notifying the RCMP, and that leadership instead deactivated an account the shooter re-registered within minutes. The complaints plead negligence, design defect, failure to warn, UCL violations, wrongful death, and survival claims. All allegations are pleaded, not found.

The September 29, 2026 order in Stacey and all related cases sets an initial case management conference for October 20, 2026, to discuss ADR, with no advance joint statement required; it also sets briefing for dismissal motions. No disposition of those motions is asserted. · Verified September 29, 2026
