What is chain of custody in evidence handling?

• A. A list of witnesses who testified at trial.
• B. A method to authenticate documents through notarization.
• C. A chain of custody only applies to blood tests.
• D. A documented, unbroken record of who has had possession of an item from acquisition to presentation in court.

Answer: (D)

Chain of custody is the documented, unbroken record of every person who has had possession of an item of evidence from the moment it is collected until it is presented in court. This continuous trail shows who collected the item, how it was stored, every transfer or handling event, and the times these events occurred. Keeping a complete chain of custody helps prove the evidence hasn’t been tampered with or altered, ensuring its integrity and making it more likely to be admitted and trusted by the court. Without this ongoing documentation, questions could arise about authenticity or reliability.

The other options miss the point: a list of witnesses pertains to who testified, not how physical evidence is tracked; notarization authenticates documents but doesn’t document the handling of evidence itself; and chain of custody applies to all kinds of evidence, not just blood tests.
