Murder book

A murder book is a collection of information about a crime, like a book that tells the story of the crime. It includes all the things that the police find out about what happened, like who was there, what happened, when it happened, and how it happened. The police use the murder book to keep track of all the evidence they have collected, like fingerprints and DNA. They also use it to keep track of all the people they have talked to, like witnesses and suspects. The murder book helps the police to solve the crime by keeping all the information in one place and making sure that nothing important gets forgotten.
