For labeling and storage to maintain integrity, which practice is essential?

• A. Use generic identifiers, improper packaging, and unrestricted access.
• B. Use unique identifiers, proper packaging, secure storage, restricted access, and complete chain-of-custody logs.
• C. Store evidence in public areas with minimal labeling.
• D. Skip chain-of-custody logs to save time.

Answer: (B)

Ensuring the integrity of labeled items hinges on precise identification, proper packaging, controlled storage, restricted handling, and a complete chain-of-custody trail. Using unique identifiers prevents mix-ups and makes each item unmistakably trackable from collection to disposition. Proper packaging protects the item from damage, contamination, or tampering during transport and storage. Secure storage and restricted access keep the evidence safe from unauthorized interference, loss, or alteration. A complete chain-of-custody log records every person who handles the item, when, and for what purpose, creating an auditable history that supports admissibility and reliability in any review.

Without these elements, confusion can arise, the physical integrity can be compromised, and the evidentiary trail can be questioned. For example, generic labels or weak packaging increase the risk of misidentification or damage; placing evidence in an unsecure or public area invites tampering; and skipping the custody log eliminates accountability for every hand the item passes through.
