North Carolina man sues OpenAI, says ChatGPT aided wife's poison plot
James Gates alleges ChatGPT gave his wife instructions on lethal doses and hiding poison in food, according to a lawsuit filed last month.
A North Carolina resident, James Gates, sued OpenAI last month, alleging that ChatGPT helped his wife plan to poison him, according to aitimes.com. The complaint claims the chatbot supplied information his wife later used in a scheme that led to criminal charges, which were ultimately dismissed.
According to the complaint, Gates found a handwritten note from his wife Cheryl in September 2025 and began to suspect he was being poisoned. The note listed various substances with dosages, marked some as "lethal", and included instructions to "clear all convos" and "log out of chat GPT".
The filing states that Cheryl asked ChatGPT about the toxic plant oleander, and that the chatbot provided information on lethal doses, hiding poison in food, and whether toxic substances are detected during an autopsy.
Cheryl was charged in 2025 with attempting to kill her husband and mixing toxic substances into food, but prosecutors dismissed the case in April this year for insufficient evidence.
OpenAI said safety is its top priority, that it blocked the user's account, and that it provided information to law enforcement.
Background
According to the complaint, Cheryl had used ChatGPT frequently since 2025 for work and household questions, and after marital problems arose she began confiding complaints and suspicions about her husband to the chatbot. Lawsuits against AI companies have increased since 2024, amid claims that chatbots worsened users' mental health or encouraged violence.
