What is the purpose of a crime scene log?

The purpose of a crime scene log primarily focuses on documenting who enters and exits the crime scene. This is crucial for maintaining the integrity of the investigation, as it helps establish a clear record of individuals who have accessed the area, including law enforcement personnel, forensic investigators, and others involved in the case. This log is vital for ensuring that unauthorized personnel do not contaminate evidence and that all interactions with the scene are accounted for, which can be important for the legal proceedings that follow.

Maintaining a log of entries and exits serves to safeguard the evidence collected, as well as to uphold the chain of custody, which is critical in criminal cases. This detailed record allows investigators to track any potential witnesses or suspects who may have been at the scene, thereby aiding in the overall investigation and subsequent prosecution.
