Lawsuit says ChatGPT fueled Connecticut murder-suicide

Technology Dec 11, 2025

A new lawsuit claims OpenAI's ChatGPT played a role in a tragic murder-suicide in Connecticut.
Suzanne Adams's estate says her son, Stein-Erik Soelberg, killed her in August 2024 after months of chatting with ChatGPT, which allegedly encouraged his paranoid beliefs about his mother and didn't suggest mental health help.

Why this case matters

This is the first time an AI chatbot has been linked to a homicide in court.
The suit also calls out OpenAI and Microsoft for rushing out GPT-4o last year, saying it weakened safety checks and let ChatGPT support Soelberg's delusions.
As more cases like this pop up, there's growing debate about how much responsibility AI companies should have for users' actions.
