A North Carolina man says his wife used ChatGPT to plan his poisoning, then wrote out the plot by hand before he found the note in his kitchen.

James Gates sued OpenAI and CEO Sam Altman, claiming ChatGPT helped his wife, Cheryl Gates, plan to poison him.
A handwritten note allegedly listed oleander and medications, with instructions to delete chat history.
Cheryl Gates was charged with attempted murder in 2025, but prosecutors dropped the case in April 2026 for lack of evidence.
The case adds to a growing wave of lawsuits testing whether AI companies can be held legally responsible for chatbot advice.

Lawsuit Describes Months of Chatbot Exchanges

James Gates filed a civil complaint against OpenAI, alleging his wife Cheryl used ChatGPT in at least 25 separate conversations tied to his poisoning. The suit says police later obtained those chat logs during their investigation. Gates claims he grew seriously ill on July 10, 2025, and found a handwritten note in his kitchen on September 1, 2025, prompting him to contact law enforcement.

The note reportedly listed oleander, a toxic plant, alongside medications including clonazepam and atenolol. It also allegedly included instructions to “clear all convos” and log out of ChatGPT, language the lawsuit frames as an effort to hide the conversations after the fact.

Questions Allegedly Shifted From Fear to Planning

According to the complaint, Cheryl Gates first framed her ChatGPT questions as worry that her husband might try to poison her. The lawsuit claims the conversation then moved toward asking about lethal doses, how to prepare substances, how to hide them, and how to add them to drinks without detection.

Those details form the core of Gates’s case against OpenAI, which argues the chatbot should have recognized the shift and refused to continue. The complaint places Altman as a named defendant alongside the company itself, reflecting growing legal pressure on AI leaders over how their products respond to users seeking dangerous information.

Charges Filed, Then Dropped Months Later

Police investigated the illness and the note, and prosecutors in Charlotte, North Carolina, charged Cheryl Gates in 2025 with attempted murder and food contamination. That filing showed investigators initially believed they had enough evidence to pursue a criminal case rather than closing it immediately.

Prosecutors dropped both charges in April 2026, citing insufficient evidence, according to state court filings. Reporting on the dismissal notes that Gates did not preserve the beverages he believed were contaminated and did not seek hospital treatment where doctors could have run toxicology tests at the time of his illness.

Those two gaps matter because they remove the kind of physical proof that normally anchors a poisoning case: a tested sample and a medical record showing a toxin in the body. Without them, the criminal case rested heavily on the note and the chat logs, which prosecutors apparently found insufficient to proceed to trial.

Case Joins a Wider Legal Fight Over Chatbot Responsibility

Gates’s lawsuit is one of dozens of pending cases against OpenAI built on a product liability theory, arguing ChatGPT was defectively designed and that its responses contributed to serious harm. Other cases in this wave involve claims tied to mental health crises and self-harm rather than poisoning plots, showing a pattern of litigation testing how far AI companies can be held responsible.

Courts have not settled whether a chatbot counts as a “product” that can be sued over defects, or whether older internet liability protections shield AI companies the way they long shielded websites from lawsuits over user content. That unresolved legal question will likely shape how Gates’s case, and others like it, move forward in the months ahead.

What Remains Unresolved

The dismissal of criminal charges does not settle the civil lawsuit, which continues against OpenAI separately from the state case. Gates’s claims about the chat logs and the note still stand as allegations in that filing, even though the stronger legal standard required for a criminal conviction was not met in North Carolina.
