Charlotte man sues OpenAI alleging ChatGPT aided wife's poisoning plot

A Charlotte man named James Gates has filed a lawsuit against OpenAI, alleging that the company's chatbot, ChatGPT, played a role in his estranged wife's plan to poison him, according to 943wsc.iheart.com.

Gates, a cybersecurity professional, reported becoming severely ill in July 2025 after consuming sodas and energy drinks at home. He later found a handwritten note from his wife listing prescription drugs labeled as "lethal" and instructions to clear ChatGPT conversations and log out, which led him to contact Charlotte police.

The police investigation included searches of the couple's home and digital records, uncovering evidence that Cheryl Harris Gates used ChatGPT to research lethal drug combinations and methods to administer them without detection. Physical evidence such as syringes and capsule-filling kits was also found.

Chat logs cited in the lawsuit indicate Cheryl Gates treated ChatGPT as a confidant, seeking advice on various matters including marital frustrations. The complaint alleges ChatGPT provided detailed operational guidance for the alleged poisoning attempt, including dosage calculations and concealment methods, and even identified local Charlotte stores where dangerous substances could be purchased anonymously.

Despite the evidence presented, prosecutors dropped attempted murder and food contamination charges against Cheryl Gates in April 2026 due to insufficient evidence, as reported by 943wsc.iheart.com.

The lawsuit was filed in San Francisco Superior Court, and the case highlights concerns about the potential misuse of AI technologies like ChatGPT in criminal activities.
