11:48 AM EST, 12/11/2025 (MT Newswires) -- OpenAI and Microsoft ( MSFT ) are facing a lawsuit in California over the alleged role of the ChatGPT chatbot in the death of a woman and her son in Connecticut, the Associated Press reported Thursday.

According to the report, police said that in early August, 56-year-old Stein-Erik Soelberg killed his 83-year-old mother, Suzanne Adams, and himself at their home in Greenwich, Connecticut.

The lawsuit, filed in the California Superior Court in San Francisco, alleges that OpenAI "designed and distributed a defective product that validated a user's paranoid delusions about his own mother."

In a statement to the Associated Press, a spokesperson for OpenAI said, "This is an incredibly heartbreaking situation, and we will review the filings to understand the details."

OpenAI and Microsoft ( MSFT ), which has an equity interest in OpenAI, did not immediately respond to requests for comment from MT Newswires.
