When should a crime scene log be established?

Establishing a crime scene log as soon as possible to enforce the perimeter is crucial for maintaining the integrity of the investigation. The log serves as an official record that documents all individuals who enter and exit the crime scene, including law enforcement personnel, forensic experts, and other authorized individuals. This practice is essential because it helps prevent contamination of the evidence and preserves the chain of custody, which is vital for legal proceedings.

By recording the times of entry and exit, and the identity of personnel at the scene, the log acts as a safeguard against any potential claims of tampering or evidence mishandling. Ensuring that this log is established promptly helps reinforce the security of the scene and protect the integrity of the investigation from the start.
