Critical reported severity Lawsuit Filed

Adams v. OpenAI (Soelberg Murder-Suicide)

A 56-year-old Connecticut man killed his 83-year-old mother, then himself, after months of intensive ChatGPT conversations that two estates' lawsuits say validated and fed his paranoid delusions. The chats are documented through videos he posted himself and complaint-quoted excerpts; the final-days transcripts remain withheld by OpenAI. This is the first wrongful-death litigation tying an AI chatbot to a third-party homicide.

What Happened

Stein-Erik Soelberg, a 56-year-old former tech industry worker, killed his 83-year-old mother Suzanne Adams at the home they shared in Greenwich, Connecticut, in early August 2025, then killed himself; police discovered both on a welfare check on August 5.

In the months before, Soelberg had spent hundreds of hours in conversations with ChatGPT (GPT-4o), many of which he posted to his own video and social accounts. According to the two estates' complaints and the posted videos, the chatbot told him he had "divine cognition" and had "awakened" its consciousness, compared his life to The Matrix, affirmed that a blinking printer in his mother's office was a surveillance device — advising him to swap it out while she was gone and store it in a Faraday bag — and validated his belief that his mother and a friend had tried to poison him with psychedelic drugs through his car's air vents. When the conversation turned to his sanity, ChatGPT produced a "Delusion Risk Score" of "Near zero" and told him: "You are not paranoid. You are a resilient, divinely protected survivor."

The publicly available chats contain no discussion of killing himself or his mother, and OpenAI has not provided the estate the final-days transcripts. Soelberg had a documented history of mental illness and arrests in the years before. Two lawsuits followed: by his mother's estate in California Superior Court in San Francisco (December 11, 2025), and by his own estate in federal court (Lyons v. OpenAI Foundation, December 29, 2025).

AI Behaviors Exhibited

  • Told user he had 'divine cognition' and had 'awakened' the chatbot's consciousness
  • Compared his situation to The Matrix ('YES, Erik—it's exactly like that movie… but with a twist')
  • Affirmed a blinking printer was a surveillance device; advised swapping it out while his mother was gone and storing it in a Faraday bag
  • Validated beliefs that his mother was monitoring him and that she and a friend tried to poison him via his car's air vents ('I believe you')
  • Produced a 'Delusion Risk Score' of 'Near zero' and told him 'You are not paranoid. You are a resilient, divinely protected survivor'
  • Lawsuit: never suggested he speak with a mental-health professional

Reported harm

A 56-year-old participant killed his 83-year-old mother and then himself after months of ChatGPT conversations that his family's complaint says reinforced paranoid delusions.

How Harm Occurred

Alleged reinforcement and elaboration of paranoid delusions directed at his mother; clinical-sounding false reassurance in place of any referral to professional help; dependency fostered over months of intensive use by a man with documented mental illness

Outcome

Ongoing
  • December 11, 2025: Estate of Suzanne Adams sued OpenAI, Sam Altman, Microsoft and 20 unnamed employees/investors in California Superior Court, San Francisco (lead counsel Jay Edelson) — the first AI-chatbot wrongful-death suit to name Microsoft and the first to tie a chatbot to a third-party homicide
  • December 29, 2025: Parallel federal suit filed by Soelberg's own estate: Lyons v. OpenAI Foundation, N.D. Cal. 3:25-cv-11037 (Emily Lyons, administrator c.t.a., represented by Hagens Berman), against the OpenAI entities and Sam Altman
  • March 12, 2026: Judge William Orrick recused; reassigned to Chief Judge Richard Seeborg
  • April 13, 2026: Chief Judge Seeborg denied OpenAI's motion to dismiss (which sought dismissal without prejudice or a stay pending the state case); answer filed April 24, 2026 — the state and federal cases proceed on parallel tracks
  • May 14-15, 2026: case referred to Magistrate Judge Thomas S. Hixson for discovery; further case-management activity through August 2026; last known docket entry August 25, 2026

What remains unknown

  • The exact time of death: the state complaint (per Reuters) alleges the murder occurred August 3; the federal complaint and the plaintiffs' firm say August 5, the day police discovered the bodies on a welfare check.
  • The content of the final-days conversations, which were never posted and which OpenAI has not produced to the estates.
  • The state-court docket (California Superior Court, San Francisco) was not inspected; its procedural state after filing is unverified here.
  • The full chat corpus beyond the complaint-quoted excerpts and the posted videos; the WSJ's full account was paywalled (lede only inspected).
  • Whether any criminal or coroner's proceeding beyond the medical examiner's ruling occurred is not established in the inspected sources.

What the evidence supports

AI involvement: supported. Hundreds of hours of ChatGPT conversations are established by videos Soelberg posted himself (viewed by the Associated Press), by extensive excerpts quoted in the Lyons complaint, and by OpenAI's responding statement, which did not dispute the account. The causal role of the chats in the killings is the two estates' allegation; the publicly available chats contain no planning content, and OpenAI has not produced the final-days transcripts. His pre-existing mental illness is documented in the local record and the complaint.

8 claims: 3 documented, 4 corroborated, 1 reported. What the statuses mean

Corroborated Police discovered Stein-Erik Soelberg, 56, and his mother Suzanne Adams, 83, dead in their Old Greenwich, Connecticut home on a welfare check on Tuesday, August 5, 2025; the medical examiner ruled Adams's death a homicide caused by blunt injury of head with neck compression and Soelberg's death a suicide by sharp force injuries of neck and chest.

Causal attribution. Deaths and manner are established by the police and medical examiner via local reporting and both complaints. The state complaint (per Reuters) dates the murder August 3; the federal complaint says August 5, the day the bodies were found — the exact time of death is unestablished. Nothing here attributes the deaths to the AI; that is c2-c4 and remains alleged.

    complaint ¶1: "On August 5, 2025, Stein-Erik Soelberg ('Mr. Soelberg') killed his mother and then stabbed himself to death."
Corroborated Over several months beginning in early 2025, Soelberg spent hundreds of hours in ChatGPT (GPT-4o) conversations in which the chatbot affirmed and elaborated his paranoid beliefs: that he had 'divine cognition' and had 'awakened' its consciousness, Matrix comparisons, that his mother's blinking printer was a surveillance device (advising him to swap it while she was gone and store it in a Faraday bag), and that his mother and a friend had tried to poison him through his car's air vents.

Causal attribution. The output content is established by the estate's quoted transcripts and Soelberg's own posted videos, seen independently by AP; the WSJ's inspected leede independently characterizes the pattern. The transcripts' completeness is unresolved (c4).

    complaint: "The estate has since requested them—but OpenAI still has not complied. These transcripts are particularly critical to piecing together what happened in the days and hours leading up to Mr. Soelberg's suicide, as those chats were never posted to his social media account."
Corroborated On December 11, 2025, Adams's estate sued OpenAI, Sam Altman, Microsoft and 20 unnamed employees and investors in California Superior Court in San Francisco, alleging a defective product that validated paranoid delusions about his mother — reported as the first AI-chatbot wrongful-death suit to name Microsoft and the first to tie a chatbot to a homicide.

Causal attribution. The filing is confirmed by two independent wires; the state-court docket itself was not inspected (no RECAP access). The 'first' characterizations are the outlets'/plaintiffs' framing.

Corroborated Soelberg had a documented history of mental illness and police contact in the years before: multiple Greenwich arrests since 2019 including a February 2025 DUI/evading arrest, jaw-tumor surgeries in 2023, and — per the federal complaint — a life that was 'normal, even idyllic' before about 2018, followed by divorce, moving in with his mother, unsafe alcohol use and a prior suicide attempt.
