What is the purpose of maintaining a chain of custody for evidence?

• A. To document the sequential handling from collection to court, ensuring integrity
• B. To describe which officer collected the evidence
• C. To track the weight of the evidence
• D. To determine the credibility of witnesses

Answer: (C)

The purpose of maintaining a chain of custody for evidence is to document every transfer and handling of the item from the moment it’s collected until it’s presented in court, ensuring its integrity. This record shows who handled the evidence, when and where it moved, how it was stored, and any changes in its condition (such as seals or packaging). By creating an unbroken trail, it helps prove the evidence hasn’t been altered, substituted, or contaminated, which is essential for admissibility in court. The other ideas—describing which officer collected it, tracking its weight, or assessing witness credibility—aren’t the primary aim of the custody record. Weight is a descriptive detail, and credibility of witnesses is evaluated through testimony and other evidence, not the custody log.
