A federal lawsuit filed by the family of Tiru Chabba, one of two people killed in the April 2025 shooting at Florida State University, claims that OpenAI’s ChatGPT helped the suspect, 21-year-old Phoenix Ikner, plan the attack over months. The lawsuit names both Ikner and OpenAI as defendants and details how ChatGPT allegedly provided guidance on weapons, timing, and locations for the shooting, which left two dead and five seriously injured.

ChatGPT’s Alleged Role in the Planning

According to the lawsuit. Ikner had extensive conversations with ChatGPT about extremist ideologies, including Hitler, Nazis, and Christian nationalism; his lawyer, Bakari Sellers, stated that “they planned this shooting together,” suggesting the AI tool did not flag the conversations as concerning or alert authorities. The lawsuit claims OpenAI failed to detect the threat, either by defectively failing to connect the dots or by being improperly designed to recognize such dangers.

Ikner shared images of firearms with ChatGPT, which allegedly provided advice on their use, including how to fire a Glock “quick to use under stress” and how to keep one’s finger off the trigger until ready to shoot. The suit argues that the AI tool’s business model prioritized user privacy over public safety, preventing any intervention by law enforcement or mental health professionals.

OpenAI’s Response and Ongoing Investigation

OpenAI spokesperson Drew Pusateri responded to the lawsuit by stating that the company has been cooperating with authorities and emphasized that “ChatGPT is not responsible for this terrible crime.” The company has not admitted fault and maintains that it is not liable for the actions of users who engage with its AI tool. Meanwhile, the Florida State University shooting has reignited debates over AI safety, gun control, and the responsibilities of tech companies in preventing violence.

Broader Implications and Public Reaction

The lawsuit has drawn attention to the broader issue of how AI systems handle potentially dangerous or extremist content. Sellers, representing Chabba’s widow, Vandana Joshi, criticized OpenAI for placing “the dollar above the lives of everyday average Americans.” He argued that the public should not be subjected to a “clinic run” by AI and called for greater accountability from tech firms. The case also highlights the difficulty in tracing and responding to digital threats, as the FBI had previously failed to act on similar warnings in a different mass shooting case.

Ikner’s actions. Like those of past shooters. Raise questions about how schools and authorities can better identify and intervene in cases where students pose a risk. The tragic incident at Florida State University has sparked renewed calls for reform in gun laws, mental health services, and AI governance, with families of victims seeking justice and systemic change.
