Which section of a supplementary report explains any updates on the investigation?

The Outcome section of a supplementary report is specifically designed to convey any updates or developments regarding the investigation. This part of the report summarizes the results of the investigation and details the current status of the case, including any actions taken, conclusions reached, or ongoing efforts. This is crucial for maintaining a clear and comprehensive understanding of the case as it progresses, as well as for informing other law enforcement personnel or stakeholders involved in the investigation.

The other sections serve different purposes: the Summary provides an overarching view of the report’s contents, the Background offers context about the case, and the Facts section presents the evidence and information gathered during the investigation. While all of these contribute to the report's entirety, it is the Outcome that specifically focuses on new developments and updates in the investigation. Thus, the Outcome section is vital for anyone reviewing the report to understand the current state of the case.
