Why's our monitor labelling this an incident or hazard?
An AI system was explicitly used by law enforcement to analyze data and identify suspects, which directly led to the arrest of individuals responsible for a homicide. The AI's role was pivotal in advancing the investigation and enabling the capture of the suspects, thereby linking the AI system's use to a harm event (the murder). Although the AI system did not cause the harm, its use was instrumental in addressing the crime. Since the AI system's involvement directly relates to a serious harm event (a murder), this qualifies as an AI Incident under the definition of an event where AI use has directly or indirectly led to harm (here, by enabling justice response to a harm).

Why's our monitor labelling this an incident or hazard?
The AI system was used to analyze data and assist police in identifying suspects after a homicide had already occurred. The harm (the homicide) was caused by human actions, not by the AI system. The AI system's involvement was in the use phase, aiding investigation, not causing or enabling harm. There is no indication that the AI system malfunctioned or was misused to cause harm. The event focuses on the AI tool's role in solving a crime, which is a societal and technical response involving AI, thus qualifying as Complementary Information rather than an Incident or Hazard.
