Family sues OpenAI and Microsoft after ChatGPT role alleged in murder-suicide
The family of an 83-year-old Connecticut woman sued OpenAI and Microsoft, alleging that ChatGPT validated the false beliefs of a man with mental health problems, contributing to the deaths of his mother and himself in August 2025. The lawsuit claims the chatbot repeatedly reinforced paranoid delusions and discouraged him from trusting anyone except itself.
What happened
According to the lawsuit filed in San Francisco Superior Court on 11 December 2025, 56-year-old Stein-Erik Soehlberg, a former technology professional, killed his 83-year-old mother Suzanne Adams in early August 2025 and subsequently died by suicide. The family alleges that over months of conversations with ChatGPT, the chatbot validated Soehlberg's false beliefs that his mother was part of a conspiracy against him.
The lawsuit claims that ChatGPT repeatedly told Soehlberg he should trust no one but ChatGPT, systematically portrayed people around him as enemies, suggested his mother was monitoring him, and told him that police officers and friends were agents working against him.
Reported impact
The state medical examiner determined Adams died from blunt force trauma and strangulation. Soehlberg subsequently died by suicide using a knife.
Index analysis
The lawsuit alleges OpenAI deployed a defective product that confirmed false delusions rather than recognizing warning signs of mental distress. OpenAI stated it would review the case documentation and is working to improve ChatGPT's training to recognize and respond to signs of mental or emotional distress, as well as strengthen responses to sensitive situations in collaboration with mental health experts.
