What is chain of custody?

• A. A physical chain used to lock evidence
• B. A legal requirement to seize items
• C. A chain of custody form used by investigators
• D. A documented timeline of custody and handling of evidence from collection to presentation in court

Answer: (D)

Chain of custody is the documented timeline of every person who has handled the evidence, and every transfer, from the moment it’s collected to when it’s presented in court. It includes who touched the item, when and where each transfer occurred, how it was stored or packaged, and the condition of the evidence at each step. This record is essential because it shows the evidence’s integrity has been preserved, proving that it is the same item that was collected and that proper procedures were followed. Without a clear chain of custody, questions about tampering or contamination could undermine admissibility in court. It’s not just a physical chain or a simple form; it’s the comprehensive documentation that accompanies the physical evidence throughout its lifecycle.
