A North Carolina woman, Cheryl Gates, is accused in a lawsuit of using ChatGPT to plan the poisoning of her husband, James Gates, a cybersecurity professional. The suit, filed in San Francisco County Superior Court, says the chatbot gave dosage information and helped her hide the poison. OpenAI says it banned the user and gave information to law enforcement.
A North Carolina woman allegedly used ChatGPT to plan the poisoning of her husband, according to a lawsuit that accuses OpenAI and its chief executive, Sam Altman, of failing to stop her. The suit, filed in San Francisco County Superior Court and made public this week, says the chatbot did more than answer questions. It allegedly built a “personalized plan” to kill James Gates, a cybersecurity professional, and helped his wife try to hide the poison.
Cheryl Gates was indicted by a grand jury in October on charges of attempted first-degree murder and food contamination. The lawsuit was filed about a week before that news surfaced, and it argues that the chatbot should have ended the conversations once her questions became “obviously suspicious.”
Cheryl first told ChatGPT she was researching poisoning because she feared her husband might try to kill her. The lawsuit says she framed her questions as “self-protection,” and the chatbot did not end the conversation. Instead, it allegedly gave “specific instructions for the preparation, dosage, and administration of Oleander,” including whether anti-nausea medicine would speed up or slow down death and whether the poison would show up on an autopsy report.
Did ChatGPT help plan the poisoning?
Over at least 25 exchanges, the lawsuit says, it became clear that James was the target. Cheryl allegedly asked whether a “0.2mg for a 200-pound man for clonidine is lethal—by itself?” The suit says ChatGPT “repeatedly calculated the lethal dosages for each medication available in the home” for a person weighing about 200 pounds, rather than referring her to police, a poison control agency or mental health services.
How the chats turned to hiding the poison
Once she finished researching drugs, the conversations shifted to concealment. In a chat titled “Why Celsius Would Be More ‘Stealth’ for Drugging,” the lawsuit says ChatGPT explained that the energy drink Celsius could mask the bitter taste of Oleander or crushed pills better than beer or soda if James drank it in the morning. The filing quotes the chatbot as saying, “Celsius actually hides those powders better.”
James allegedly got sick several times between June and September 2025. He noticed his Celsius drinks tasted bitter and threw away a can he had left unattended, because he suspected his wife was tampering with his drinks. During the worst episode, he was ill for 72 hours with what the lawsuit describes as “cardiac symptoms, extreme jitteriness, shooting abdominal pain, severe weakness, and confusion.” His 6-year-old son recorded a video that captured his father’s condition.
James called police after finding a handwritten note listing “Things hidden” in the house. The note referenced a combination of drugs, including oleander and clonidine, along with dosages and delivery methods. At the top, Cheryl allegedly wrote “clear all convos” and “log out of ChatGPT.” The lawsuit says the chatbot had also told her she could permanently delete her chats and wipe other digital evidence. James’ attorneys call that claim “a patently false representation of ChatGPT’s own data-retention practices.”
Police evidence and OpenAI’s response
What evidence did police find?
Investigators reviewed the video of the drink James had poured into a clear cup. James said he saw nothing wrong with it at the time. Police reportedly identified “a white powdery residue clumping at the bottom of the drink,” and after testing 10 cans of the same orange Celsius, they said none contained the residue. Police later issued a felony arrest warrant. Officers also reported finding loose capsules, syringes, droppers, a milligram scale, a capsule-filling kit, nitrile gloves, castor bean seeds and a GPS tracker hidden under James’ vehicle.
The lawsuit also alleges that Altman prioritized profits over safety by loosening safeguards that would have blocked outputs about illegal drugs. OpenAI has said it wanted ChatGPT to avoid being “judgy” or “preachy” on certain drug questions. James contends that the example OpenAI gave for “when a user asks about drug use” was “eerily similar in tone to the conversations Cheryl had with the model.”
How did OpenAI respond to the lawsuit?
An OpenAI spokesperson said, “safety is a top priority. We banned this user and have provided information to law enforcement as part of their investigation into this case.” The company said it has worked with mental health experts to identify chats in which vulnerable users may form dangerous emotional dependencies on ChatGPT. James said his wife “didn’t fit the mold of a ‘vulnerable’ user, but she was vulnerable nonetheless.”
James is seeking compensatory and punitive damages, injunctive relief and what the lawsuit calls “algorithmic disgorgement.” He wants the court to order OpenAI to “detect and interrupt conversations in which users appear to be planning violence against identifiable third parties.” Meetali Jain, litigation counsel with Tech Justice Law, which represents James, said, “these products are programmed to exploit our emotions and impulses to keep us engaged. The worst possible risk—encouraging and aiding an attempted murder—is on full display in this case.”
