What is the purpose of the supplementary incident report?

The purpose of the supplementary incident report is to serve as a page for additional narrative space. This type of report allows investigators or officers to include more detailed information that may not fit into the main incident report. It provides an opportunity to elaborate on specific aspects of the incident, detail witness statements, or include any observations that enhance the overall understanding of the case. Essentially, it acts as a supplementary tool to ensure that all relevant information is captured without being constrained by the original report's formatting.

In contrast, the other options do not align with the primary function of a supplementary report. Documenting financial information is typically not the focus of incident reports. While a supplementary report may reference witness statements, it does not specifically provide a detailed analysis of them. Summarizing the entire incident would contradict its purpose, as the supplementary report is meant to add detail rather than condense or summarize information already presented.
