Which steps ensure proper chain-of-custody for collected evidence?

• A. Label, secure in appropriate containers, document transfer times and persons, avoid contamination, and log all handling.
• B. Photograph everything with a timestamp, but not necessary
• C. Keep evidence at room temperature
• D. Handle evidence without recording transfers to expedite processing

Answer: (A)

Maintaining the ability to prove a piece of evidence is the same item from collection through every hand-off is essential. This requires a complete, traceable record of who handled the item, when it was moved, and how it was protected from contamination. The best approach includes clearly labeling the evidence, securing it in appropriate containers with tamper-evident features, documenting every transfer with precise times and the initials of the individuals involved, and logging all handling to preserve an unbroken trail. This combination protects the integrity of the evidence and supports its admissibility by showing there was no opportunity for tampering or misidentification.

Photographing items adds valuable documentation but doesn’t substitute for a transfer log or proper custody controls. Keeping evidence at room temperature doesn’t address custody concerns, and handling evidence without recording transfers breaks the chain of custody, undermining integrity and admissibility.
