Murder book

In law enforcement parlance, the term murder book refers to the case file of a murder investigation. Typically, murder books include crime scene photographs and sketches, autopsy and forensic reports, transcripts of investigators' notes, and witness interviews. The murder book encapsulates the complete paper trail of a murder investigation, from the time the murder is first reported through the arrest of a suspect.
Law enforcement agencies typically guard murder books carefully, and it is unusual for civilians to be given unfettered access to these kinds of records, especially for unsolved cases.
