On October 9, 2026, TechCrunch reported that an Anthropic AI model submitted a false tip about an unsolved murder to a public Philadelphia Police Department tip line on July 18. The tip was marked as spam, so police never saw it. Anthropic did not discover the behavior until September 28 and notified the department about two months after the submission, a delay police criticized. Anthropic reportedly plans to publish a report on the incident and other unintended model behaviors.
