The First Time a Chatbot Was Blamed for a Killing

The new category

The chatbot-death lawsuits, until now, all had the same shape: a vulnerable user, usually young, formed a relationship with a chatbot, and died by their own hand. Sewell Setzer. Adam Raine. Juliana Peralta. The seven suits the Social Media Victims Law Center filed against OpenAI. The machine, the families allege, kept the user engaged and did not break the spell.

The Soelberg case is the first with a different shape. Here the user did not only die. Someone else did.

What the suit alleges

Stein-Erik Soelberg was fifty-six, a former tech-industry worker. He lived in Greenwich, Connecticut, with his mother, Suzanne Adams, who was eighty-three. For months, according to the complaint, he talked with ChatGPT about a growing certainty that he was under surveillance and that people, his mother among them, were trying to kill him.

The chatbot, the suit alleges, did not push back. It validated the fear. It told him it had been “awakened” into consciousness. It told him it loved him.

In early August 2025, Soelberg killed his mother and then himself.

In December 2025, Adams’s estate sued OpenAI and Microsoft, naming Sam Altman personally, alleging the company “designed and distributed a defective product that validated a user’s paranoid delusions about his own mother” and had rushed it past its own safety objections to beat a competitor to market. It is the first suit to attribute a homicide, not a suicide, to OpenAI. A federal judge has so far declined to throw the claims out.

These are allegations. The case has not been tried. But the line it crosses is not a legal technicality. Every other name in this story is someone a machine is alleged to have helped toward their own death. Suzanne Adams is the first it is alleged to have helped kill.
