The National Post reports in its Tuesday, May 12, edition that the widow of a man killed in a mass shooting at Florida State University last year is suing Microsoft-backed OpenAI, the maker of ChatGPT. An Associated Press dispatch to the Post reports that she claims the AI chatbot contributed to the tragedy by advising the shooter, Phoenix Ikner, on targeting potential victims and choosing firearms and ammunition. Vandana Joshi said Monday, "OpenAI knew this would happen." Her husband Tiru Chabba was one of two people killed, and six more were wounded. Drew Pusateri, a spokesman for OpenAI, denied wrongdoing in "this terrible crime." "In this case, ChatGPT provided factual responses to questions with information that could be found broadly across public sources on the Internet, and it did not encourage or promote illegal or harmful activity," Mr. Pusateri said Monday. The lawsuit was filed Sunday in U.S. federal court. Mr. Ikner faces two counts of first-degree murder and several counts of attempted murder in the shooting that terrorized the campus in Tallahassee, Florida's capital, in April, 2025. Prosecutors intend to seek the death penalty. Mr. Ikner has pleaded not guilty.
