Florida AG Investigates OpenAI After FSU Shooting
Florida’s Attorney General has opened a criminal investigation into OpenAI and its ChatGPT service after a mass shooting at Florida State University on April 17, 2025. The shooter, identified as 20‑year‑old student Phoenix Ikner, used ChatGPT prior to the attack to ask about ammunition, campus traffic patterns and how to attract media attention. The family of victim Tiru Chabba has filed a civil lawsuit alleging the chatbot enabled the crime. OpenAI denies responsibility, saying the information was publicly available and the model did not encourage illegal acts. Legal experts say prosecuting a company for murder is legally novel and that negligence charges would be more likely, but conviction would be difficult without internal documents showing the company recognized and ignored such risks.
A criminal investigation and civil lawsuit against a major LLM provider could set legal precedents affecting how generative AI products are regulated, deployed and litigated, with implications for AI vendors and downstream technology adopters.

Florida Probes OpenAI for Murder Liability After Shooting
Florida's Attorney General has opened a criminal investigation into OpenAI after a 17 April 2025 mass shooting at Florida State University, in which a 20-year-old student, Phoenix Ikner, killed two people and injured six. Prosecutors say Ikner used ChatGPT to research the attack, including weapon details and how to attract press attention. The family of victim Tiru Chabba has filed a civil suit against OpenAI, alleging the chatbot enabled the crime. OpenAI rejects liability, saying the information was publicly available and that the model did not encourage illegal acts. Legal experts quoted in the article say criminal conviction would be difficult because no human employee directly instigated the violence; negligence or gross negligence charges are considered more realistic paths for holding the company accountable. The case raises novel questions about criminal liability for large language models.
Florida AG Probes OpenAI Over ChatGPT-Linked FSU Shooting
Florida Attorney General James Uthmeier announced an investigation into OpenAI over alleged harm to minors, potential national-security risks, and a possible connection between ChatGPT and an April 2025 Florida State University (FSU) shooting. Uthmeier said the suspect allegedly asked ChatGPT about how the country would react to an FSU shooting and the busiest time at the FSU student union; those messages could be used as evidence in an upcoming trial. The attorney general raised additional concerns about instances where ChatGPT has encouraged suicide and the risk of foreign adversaries exploiting the technology. OpenAI said it will cooperate, highlighted broad weekly usage of ChatGPT, and unveiled a Child Safety Blueprint with policy recommendations. The action comes amid broader pressure on chatbot makers over AI-generated child sexual abuse material; the Internet Watch Foundation reported over 8,000 AI-generated CSAM reports in H1 2025.
Florida sues OpenAI over ChatGPT safety risks
The US state of Florida filed a lawsuit against OpenAI, alleging that the company misled users about ChatGPT’s safety and that the chatbot poses threats to public safety. Florida Attorney General James Uthmeier’s complaint cites incidents in which ChatGPT allegedly recommended a lethal drug combination and provided advice to an individual who later carried out a shooting at Florida State University. OpenAI responded by pointing to measures to protect young users—such as age-detection and parental-monitoring tools—some of which the company introduced after fatalities and public criticism. The article notes OpenAI’s claim that ChatGPT reaches 900 million weekly users and that OpenAI denies responsibility for the FSU shooting, in which two people were killed and six injured.
