OpenAI’s AI chatbot helped police catch a Florida man plotting a murderous revenge spree against his ex‑girlfriend. The suspect posted chilling revenge vows to ChatGPT after a brief breakup.
AI Bot Flags Violent Threats
Darren Zhou, 25, a former Goldman Sachs analyst, posted chilling revenge vows to ChatGPT after a six‑month breakup, court filings show. He believed the bot would keep his threats private.
“I’m gonna kill her by the end of this month. If I can’t have her then nobody can,” he wrote, according to the indictment.
Investigators say Zhou used the bot to draft step‑by‑step plans to stalk, kidnap, rape and murder the 21‑year‑old victim, even describing a gun‑filled attack and a suicide pact. He detailed how he would draw a gun, kill her, then shoot himself.
He claimed he waited at her gym with weapons, sent her photos of zip ties, latex gloves and firearms, and texted threats of sexual assault. He said the images proved his intent to assault her.
OpenAI’s safety system flagged the explicit threats, prompting the company to hand over two months of Zhou’s chat logs to federal agents, who passed them to the Palm Beach County Sheriff’s Office. The firm acted quickly to comply with its safety protocols.
A deputy reviewing the logs said the messages demonstrated a “pattern of rehearsal and planning,” not vague emotional outbursts, the agency reported. Authorities said the content showed clear intent and organized steps.
While Zhou confessed his fantasies online, he terrorized his ex in real life, bombarding her with burner‑app texts and location drop‑ins that identified her gym. She reported the harassment, fearing for her safety.
Deputies arrested Zhou in May; he faced felony charges of aggravated stalking, written threats to kill and illegal cell‑phone use, crimes that carry up to 25 years in prison. The indictment outlined a serious threat to public safety.
In a surprise courtroom outcome, Zhou avoided jail time and a felony record after prosecutors struck a plea deal on August 13, sentencing him to eight years of probation. Judge Scott Suskauer granted the deal because the victim consented.
Judge Scott Suskauer warned that “no one deserves the type of conduct you exposed this lady to” and told Zhou to “get over it and move on.” The judge emphasized the need for accountability.
Zhou’s attorney called the episode a “difficult mental health episode,” insisting his client owned no guns and was “not a violent person.” The lawyer argued the threats were fantasy, not reality.
The court ordered Zhou to wear an ankle monitor for two years and to complete mandated counseling. He must remain under supervision while receiving treatment.
