What is a primary purpose of chain of custody in investigative documentation?

• A. To authenticate evidence
• B. To speed up the process
• C. To obscure the source
• D. To satisfy formatting guidelines

Answer: (A)

Chain of custody is about proving evidence remains authentic and unaltered from the moment it’s collected to when it’s used or presented. It creates a clear, dated, signed trail of every person who handled the item, where it was stored, and any transfers or changes in condition, often including seal numbers and storage details. This documented history shows the evidence is the same object and has not been tampered with, which is essential for its reliability and admissibility in court. It isn’t about speeding things up, obscuring sources, or meeting formatting rules—all of that is secondary to ensuring the evidence can be trusted.
