What action best maintains the chain of custody for evidence?

• A. Declaring ownership of the evidence by the first officer.
• B. Leaving the evidence in a patrol car.
• C. Documenting every transfer of custody and securing the evidence.
• D. Sharing the evidence with any bystander.

Answer: (C)

Maintaining the chain of custody means keeping evidence under control from collection to court, with a clear, verifiable record of every person who handles it and every change in possession. The best action is to document every transfer of custody and secure the evidence, because a detailed log shows who had access and when, and securing the item in proper storage protects it from tampering, damage, or loss. This creates an unbroken, auditable trail of custody that supports the integrity and admissibility of the evidence in legal proceedings. The other options fail because simply declaring ownership doesn’t establish control or track handling; leaving the evidence in a patrol car risks loss, contamination, or tampering; and sharing with a bystander introduces untracked access and undermines the ability to prove a continuous chain of custody.
