Which of the following is a key element of the chain of custody?

• A. Weather at collection.
• B. Seals remain intact during every transfer.
• C. The color of the investigator's uniform.
• D. The investigator's personal opinion about value.

Answer: (B)

Preserving the chain of custody means showing an unbroken, documented trail of who handled the evidence and when, so its integrity is never in question. The most critical element is that tamper-evident seals remain intact during every transfer. If a seal is broken, missing, or replaced, it signals potential tampering and breaks the continuity of possession, which can cast doubt on the evidence in court. That’s why keeping seals intact, along with proper labeling and a transfer log that records each person who handles the item, is essential to maintaining the evidence’s credibility from collection to presentation.

Weather at collection doesn’t establish custody or prove who handled the item, and the color of the investigator’s uniform has no bearing on the evidence’s custody. The investigator’s personal opinion about value is irrelevant to whether the chain of custody was properly maintained.
