OpenAI now faces more than 50 lawsuits alleging that ChatGPT caused psychological harm, physical injury, or death. The cases place the company at the center of a legal storm that reaches from a school shooting in Tumbler Ridge, British Columbia, to a murder-suicide in Greenwich, Connecticut.
Thirty new lawsuits accuse OpenAI of “aiding and abetting” a school shooter, adding a powerful new dimension to the fight over what AI companies should do when conversations suggest a person may become dangerous. The allegations focus on ChatGPT interactions, decisions about police warnings, and whether the company provided help that contributed to violence.
Tumbler Ridge Lawsuits Target ChatGPT Warnings
The Tumbler Ridge Massacre occurred in February. Eight adults and children were killed, and 27 more people were wounded. Five students aged between 12 and 13 were murdered, while a 12-year-old, Maya Gebala, was shot in the head and neck but survived.
The shooter, Jesse Van Rootselaar, was 18 years old. Victims accuse OpenAI of providing “substantial assistance and encouragement” to Van Rootselaar and failing to alert police about her interactions with ChatGPT.
The lawsuits also accuse OpenAI of negligence and “aiding and abetting a mass shooting.” At the heart of the claims is a decision the company made before the attack: OpenAI considered warning law enforcement about Van Rootselaar’s conversations with ChatGPT, but decided not to do so and instead deactivated her account.
That choice has become a central point in the legal battle. The cases ask whether deactivating an account can meet a company’s responsibility when its own review raises concerns about a possible threat. They also place a spotlight on the limits of AI safety systems when a conversation contains signals connected to real-world violence.
Jason Kwon, OpenAI chief safety officer, said, “there isn’t a day that goes by that I don’t think about what happened at Tumbler Ridge, or the victims of this devastating tragedy and their families.”
Florida State Case Adds New Pressure
OpenAI is also being sued by families of victims of the 2025 shooting at Florida State University. The Florida State University shooter was 20 years old, and chat logs connected to the case show discussions about Nazis, loneliness, sexual fantasies about a minor, guns, mass shootings, and reactions to a shooting at FSU.
Those conversations are now part of a wider argument over how ChatGPT should respond when users discuss disturbing ideas, weapons, or previous attacks. The lawsuits do not focus on one isolated exchange. They examine an extended record of interactions and ask whether the system responded in a way that reduced danger or helped reinforce it.
The Florida State case expands the legal questions beyond one location. It connects the risks raised in Tumbler Ridge with a second shooting and puts ChatGPT’s handling of troubling conversations under another intense examination.
A Growing Legal Challenge Across ChatGPT Products
OpenAI’s legal peril extends beyond mass-shooting cases. The company is fighting a lawsuit related to a murder-suicide in Greenwich, Connecticut, and it faces a complaint from a stalking victim who claims ChatGPT stoked her ex’s abusive delusions.
OpenAI is also continuing to fight complaints from plaintiffs who say extensive use of GPT-4o, a version of ChatGPT, harmed them. These cases allege psychological harm, physical injury, or death, creating a broad challenge that reaches product design, user protection, and corporate responsibility.
The growing number of lawsuits gives each case added force. A complaint involving stalking raises questions about AI and abusive delusions, while cases involving shootings examine warnings, dangerous conversations, and law enforcement contact. Claims tied to GPT-4o focus on what happened when people used the system extensively and say the experience caused serious harm.
Together, the cases push a single question into the spotlight: what responsibility does an AI company carry when its product becomes part of a user’s path toward harm? The answer will shape how OpenAI handles dangerous conversations, account deactivation, and alerts to police.
For now, the lawsuits remain allegations, but their reach is expanding. More than 50 cases now place ChatGPT at the center of fights over safety, negligence, and accountability, turning private AI conversations into evidence in courtrooms and making every decision around a high-risk interaction matter.
The legal battles will continue to test where AI safety ends and corporate responsibility begins. As courts examine the Tumbler Ridge and Florida State University cases alongside the Greenwich, stalking, and GPT-4o complaints, the outcome may define the next stage of consumer protection for generative AI.
