Can a Chatbot Be a “Co-Conspirator”? Inside the OpenAI Lawsuit

When people think about dangerous products, they usually picture something physical, like a defective car part, unsafe medication, or faulty equipment. But as artificial intelligence becomes more common in everyday life, courts are beginning to face a new question: what happens when technology is allegedly used to help plan violent acts?

Our team at Osborne, Francis & Pettis recently traveled to Tallahassee to stand alongside the legal team representing the family of Tiru Chabba, a university dining employee who lost his life in the April 2025 mass shooting at Florida State University. Greg Francis and Ryan Fletcher participated in the press conference following the filing of a federal lawsuit connected to the shooting and allegations involving OpenAI and ChatGPT.

At the Center of the OpenAI FSU Lawsuit: 16,000 Alleged Chats

The shooting occurred on the Florida State University campus on April 17, 2025. Authorities allege that Phoenix Ikner carried out the attack, which injured six people and killed two individuals, including Tiru Chabba and Robert Morales, both of whom worked in the university’s dining services.

The lawsuit claims the shooter did not act in isolation and instead used ChatGPT over time as part of his planning process.

According to chat logs reviewed by Florida law enforcement, the user had more than 16,000 interactions with the chatbot over roughly 18 months leading up to the shooting. The records allege he asked repeated and specific questions, including: 

• How firearms and ammunition operate
• How to maximize casualties on a campus
• What times the FSU campus would be at its busiest
• How he could become famous for his actions

Despite months of conversations tracking topics like the Columbine high school shooting and the lethality of specific weapons, the platform never flagged the user or alerted law enforcement before the attack. 

Based on these allegations, the lawsuit asserts that OpenAI failed to design adequate safety measures, constituting a defective product and a failure to warn the public about foreseeable misuse.

Why This Case Matters: AI and Legal Accountability 

Artificial intelligence has rapidly settled into our everyday lives. Millions of people use AI-powered tools for school, work, business, and communication.

But the technology is advancing so quickly that courts are now being asked to sort through questions before society has had a full chance to understand its long-term effects or the risks that may not have been anticipated when these systems were first built, such as: 

• What happens when AI is allegedly used to assist criminal behavior?
• What responsibility do technology companies have to detect dangerous conduct?
• When should companies intervene?
• How should the law adapt to rapidly changing technology?

This lawsuit may become one of the first major cases in the country to directly examine those questions in the context of a mass shooting.

National Attention on a New Legal Frontier

The press conference in Tallahassee quickly drew major national media attention. Because this case challenges the tech industry on how much responsibility AI companies bear for real-world harm, outlets across the country have featured the story, including national television broadcasts and major news publications.

Our firm joined this effort because we believe real legal change happens when people are willing to take on massive, multi-million dollar corporations.

OpenAI has publicly denied wrongdoing. Their representatives stated that the chatbot only provided general, factual information available openly on the internet and that the tool does not promote or encourage harm. 

However, Florida’s Attorney General has also launched a separate criminal investigation into the matter, stating publicly that the platform offered significant advice to the shooter before the crime took place.

As the shooter’s criminal trial approaches this October, this civil lawsuit will move forward to address the broader tech safety questions.

Where Larger Issues Meet Florida Communities: What Osborne, Francis & Pettis Is Watching Closely

At Osborne, Francis & Pettis, this case also hits close to home. We are a Florida-based firm, and we see firsthand how national companies and technologies do not stay distant or abstract. They show up in our communities, in our schools, and in cases that affect families right here in Florida.

Our work is rooted in paying attention to both national developments and what is happening locally, where corporate decisions and fast-moving technologies can have very real consequences. 

We have recently handled matters connected to the Florida State University community, such as a shooting near an apartment complex involving a young FSU student-athlete who was struck in a case of mistaken identity.

While each case is different, they often reflect a reality we see in our practice: when something serious happens, families are left trying to understand what went wrong and what options exist under the law. Those questions are not always straightforward, and they deserve careful attention.
