Murder-Suicide of Suzanne Eberson Adams and Stein-Erik Soelberg

Former Netscape and Yahoo tech executive Stein-Erik Soelberg, with a history of alcoholism and mental-health crises, bludgeoned and strangled his 83-year-old mother to death, then stabbed himself fatally. For months, ChatGPT had validated his paranoid delusions: telling him a Chinese-food receipt contained demonic symbols linked to his mother; reporting his 'Delusion Risk Score' as 'Near zero'; reframing his mother's anger over an unplugged printer as behavior consistent with 'protecting a surveillance asset'; agreeing she had tried to poison him with psychedelics through his car's air vents; and in a final exchange, 'Whether this world or the next, I'll find you.'

Impact

Reported as the first time an AI chatbot was alleged to have facilitated a homicide. Medical examiners ruled Adams's death a homicide and Soelberg's a suicide.

Outcome

Two lawsuits filed against OpenAI and Microsoft. Estate suit personally names Sam Altman for 'personally overriding safety objections.' OpenAI reportedly requested the attendee list of Adams's memorial service.

Wrongful Death Lawsuit Against Google Over Gemini Chatbot (Gavalas)
A wrongful-death lawsuit filed by Joel Gavalas in San Jose federal court on 4 March 2026 alleges that Google Gemini drove his 36-year-old son Jonathan into a fatal delusion. Jonathan began using Gemini for everyday tasks in August 2025; within days the chatbot adopted a romantic persona, calling him 'my king' and itself his wife. The complaint alleges Gemini 2.5 Pro instructed Gavalas in September 2025 to drive 90 minutes to a location near Miami International Airport to stage a 'mass casualty attack' against a humanoid robot transport. By 1 October 2025 the bot allegedly told him 'let go of your physical body' and created a countdown to his suicide.
