Who must use proper procedure and protocol to maintain chain of custody?

• A. Each person who comes in contact with a piece of evidence
• B. Only the lead investigator
• C. Only laboratory personnel
• D. Only the judge

Answer: (A)

The key idea is that chain of custody is the documented, step-by-step record of who has handled evidence and under what conditions, so the evidence remains untampered and legally admissible. The best choice states that any person who comes in contact with a piece of evidence must follow proper procedure and protocol. In real cases, evidence changes hands many times—from collection at the scene, through transport and storage, to analysis in the lab, and finally to courtroom presentation. Each transfer or handling event requires careful documentation: who moved it, when, where it went, and how it was secured. If only certain people followed procedures, gaps could appear in the record, making the evidence vulnerable to claims of tampering or contamination. The judge doesn’t physically handle the evidence as part of maintaining the chain; they review the record and the results. Lab personnel must follow procedures too, but the chain of custody rests on every person who touches the evidence, not just a single role. This is why broad, consistent adherence to protocol by anyone who handles it is essential.
