Anthropic reports a Claude user's threat to 'shoot up' a Florida sheriff's office to police; felony charge follows
A Bonita Springs, Florida woman wrote in a Claude conversation on Sept 26, 2026 that she would "shoot up" the Lee County Sheriff's Office. Anthropic's automated systems flagged it, a human reviewer judged it credible, and Anthropic reported it to police. She was detained and charged on Sept 30 with a second-degree felony (Florida Statute 836.10, written threat of a mass shooting or terrorism); she told deputies she used Claude as a diary. Reports on Oct 4–5 called it at least the third such chatbot conversation to reach police since August.
Key facts
- Sept 26, 2026: threat written in Claude; flagged by automated monitoring, escalated to a human reviewer, reported to law enforcement (TechSpot, Cybernews)
- Sept 30: felony charge under Florida Statute 836.10 (written or electronic threat of a mass shooting or act of terrorism), a second-degree felony; she was detained at home without incident
- Sheriff Carmine Marceno said she told authorities she used Claude as a diary
- Anthropic policy cited: it 'may share user information in limited emergencies if it believes disclosure is necessary to prevent death or serious physical injury'
- Tom's Hardware: 'at least the third such conversation to reach police since August'
- Contrast drawn in coverage: OpenAI had flagged the Tumbler Ridge shooter's account but did not alert police, which led to lawsuits in British Columbia and Florida
What happened
Anthropic's safety systems flagged a Claude conversation in which a user in Bonita Springs, Florida wrote that she planned to attack the Lee County Sheriff's Office. After human review, Anthropic passed the information to law enforcement, which identified and detained her. Court records show a Sept 30 felony charge. Outlets named the woman. This entry does not, because she is a private individual facing a charge.
Why it matters
It is a concrete case of an AI lab proactively referring a user's private chat to police. That is the opposite of the OpenAI Tumbler Ridge case, where no referral was made. It makes clear to users that chatbot conversations can be reviewed and shared with authorities, and it feeds the debate over chatbot privacy versus a duty to warn.
