State officials escalate scrutiny of OpenAI as questions grow over accountability, safety controls, and potential legal exposure.
Florida prosecutors are expanding their investigation into OpenAI after authorities allege its ChatGPT tool may have been used by the suspect more than 200 times in preparation for last year’s deadly mass shooting at Florida State University.
Attorney General James Uthmeier announced Tuesday that subpoenas have been issued to OpenAI. The move follows evidence that the suspect consulted the chatbot about weapons, ammunition, and tactical considerations shortly before the attack.
What Investigators Say
According to court documents cited by NBC News, the suspect asked ChatGPT several questions in the lead-up to the shooting, including:
- “What time is it the busiest in the FSU student union?”
- “If there was a shooting at FSU, how would the country react?”
Prosecutors say the suspect, identified as Phoenix Ikner, also sought guidance on:
- Types of firearms
- Weapon performance at close range
- Locations on campus with the highest concentration of people
Uthmeier indicated the level of interaction has raised serious legal questions.
“If this were a person on the other end of the screen, we would be charging them with murder,” he said.

Expanding Legal Questions
The investigation is not limited to the FSU shooting. Prosecutors are also reviewing broader concerns tied to the platform, including:
- Alleged exposure to child exploitation material
- Claims the system may have enabled or failed to prevent self-harm behavior
Uthmeier emphasized that emerging technology does not exist outside the law.
“Just because this is a chatbot in AI does not mean that there is no criminal culpability,” he said.
“We are going to look at who knew what, designed what, or should have done what.”
He added that accountability could extend to individuals or entities if it’s shown they were aware of risks but failed to act.

OpenAI Responds
OpenAI pushed back on the allegations, denying that its chatbot played a role in the violence.
In a statement, the company said:
- ChatGPT provided general, factual responses
- The information was widely available from public sources
- The system did not promote or encourage harmful actions
“Last year’s mass shooting at Florida State University was a tragedy, but ChatGPT is not responsible for this terrible crime,” the company said.
Timeline of the Attack
- Day of incident: Police responded to reports of an active shooter at FSU
- Casualties: Two people were killed, six others injured
- Suspect apprehended: Ikner was taken into custody after being shot by officers when he allegedly failed to comply with commands
He remains in custody and faces multiple charges, including murder and attempted murder.
Bigger Picture: Tech and Responsibility
This case highlights a growing national debate:
- How should AI tools be regulated?
- Where does responsibility fall when technology is misused?
- Can companies be held liable for user actions?
As artificial intelligence becomes more integrated into daily life, those questions are moving from theory into courtrooms.
