Family of FSU Shooting Victim Sues OpenAI Over ChatGPT Use

Lawsuit Filed Against OpenAI

The family of Tiru Chabba, a victim of a shooting at Florida State University (FSU) in April 2025, has filed a federal lawsuit against OpenAI, the creator of the ChatGPT chatbot. The lawsuit, filed by Chabba's widow, alleges that the suspect who carried out the attack used ChatGPT to plan and prepare for the shooting.

According to the legal filing, the alleged gunman engaged in extensive conversations with the chatbot over a period of several months. Attorneys for the family claim that the suspect carried out the attack using "input and information" provided during these interactions with ChatGPT.

Lawyers representing the family asserted that OpenAI has "put the dollar above the every day human". The lawsuit cites specific chat logs between the alleged shooter, identified as Phoenix Ikner, and the AI tool leading up to the event.

State Criminal Investigation

In addition to the civil lawsuit, the state of Florida has initiated a criminal investigation into OpenAI. Florida Attorney General James Uthmeier announced the probe after reviewing conversation logs between ChatGPT and the FSU student accused of the killings.

The investigation aims to determine if the generative AI chatbot could bear legal responsibility for the mass shooting. The probe follows claims that the accused gunman consulted the AI chatbot before killing two people.

Background of the Incident

The shooting occurred in April 2025 at Florida State University. The attack resulted in the deaths of two people. Phoenix Ikner has been identified as the suspect in the case.

The legal actions follow a review of the digital interactions between the suspect and the AI, with both the civil plaintiffs and the state attorney general focusing on the nature of the information provided by the chatbot during the months preceding the violence.
