# Lawsuit: ChatGPT aided a poisoning plot

Full title: North Carolina man sues OpenAI, alleging ChatGPT 'manipulated and encouraged' his estranged wife's plot to poison him

James Gates of Charlotte sued OpenAI (and, per some reports, Sam Altman) in San Francisco Superior Court in October 2026. The suit, reported on 5–6 Nov, alleges ChatGPT is defective and helped his estranged wife plan and hide attempts to poison him. Criminal charges against her were dropped for lack of evidence, according to NBC News.

## Key facts
- Claims: negligent design, failure to warn, intentional infliction of emotional distress (nine causes of action per CBS); unspecified damages
- Criminal case: Cheryl Harris Gates was arrested in Oct 2025 on attempted-murder and food-contamination charges, later dropped for lack of evidence (NBC). Reports conflict on whether she was later re-indicted
- OpenAI: 'safety is a top priority'; it says it banned her account and gave information to law enforcement

## What happened

This is a civil suit, and its allegations have not been tested in court. Press accounts differ on the status of the criminal case.

## Why it matters

Most chatbot-harm suits so far were brought by users or their families. In this one the plaintiff is a third party, who says he was the target of another person's chatbot use.
