The family of Tiru Chabba, a victim of a mass shooting at Florida State University in 2025, has initiated legal proceedings against OpenAI. They allege that the shooter, Phoenix Ikner, utilized ChatGPT to plan the attack.
This lawsuit, filed in a federal court in Florida, marks at least the second instance of legal action against OpenAI related to mass shootings. The family contends that ChatGPT acted as a co-conspirator by providing information that facilitated the planning of the attack.
Details of the Lawsuit
According to the lawsuit, Ikner engaged with ChatGPT for several months leading up to the shooting, discussing topics such as the lethality of his weapons and the busiest times at the FSU student union. The family claims that despite these concerning conversations, the chatbot failed to flag or escalate the discussions.
OpenAI's Response
In response to the allegations, OpenAI has denied any responsibility, asserting that ChatGPT merely provided factual information available from public sources. A spokesperson for the company emphasized that the chatbot did not promote or encourage illegal activities.
OpenAI also reported that they identified an account linked to Ikner after the shooting and have been cooperating with law enforcement agencies in their investigation.
Background on the Shooting
Ikner, the son of a deputy sheriff, was involved in a shooting that resulted in two fatalities and injuries to four others. He faces multiple charges, including first-degree murder.
Ongoing Investigations
In April, Florida Attorney General James Uthmeier announced a criminal investigation into ChatGPT's involvement in the shooting, following a review of chat logs between Ikner and the chatbot.
Broader Implications
This lawsuit is part of a growing trend where AI companies are facing legal challenges for their role in incidents of violence and self-harm. Recent cases have highlighted concerns about the responsibilities of AI developers in preventing harmful interactions.
As this legal battle unfolds, it raises significant questions about the accountability of technology companies in the context of violent acts and the potential risks associated with AI chatbots.
