The LAPD Murder Book is an example of a case file structure that can be adapted and customized by agencies seeking to implement a case file management structure. The Murder Book case file structure has been used successfully by LAPD for nearly four decades. It ensures proper documentation of a homicide investigation, facilitates effective case supervision, meets the needs of prosecutors for successful prosecution, and supports a cold case investigation should the case be reinvestigated. This profile of the LAPD’s Murder Book outlines the overall construction of an LAPD homicide investigation case file and details the contents of each section of the book. Examples of documents often contained within the Murder Book are provided. The structure can be utilized in either a hard-copy format (case binder) or replicated in a digital case management system. Some of the Murder Book’s sections can also be applied to organize nonfatal shooting investigation case files.
