A laptop that was in the evidence room of a police station is missing.

Chain of custody documentation is a record of the sequence of custody, control, transfer, analysis, and disposition of physical or electronic evidence. It is important to maintain a chain of custody to ensure the integrity and authenticity of the evidence, and to prevent tampering or contamination. If a laptop that was in the evidence room of a police station is missing, the best reason to refer to chain of custody documentation is to determine which party had the machine and when. This can help to identify the possible suspects, locate the missing laptop, and verify if the evidence on the laptop was compromised or not
