Which elements should be captured in a chain-of-custody log for an evidence item, and who should sign routinely?

• A. Item ID, description, date/time, custodian, transfer recipient, purpose; signatures from all custodians.
• B. Item name, color, location found; signatures from the laboratory supervisor.
• C. Date/time of receipt, chain-of-custody form number; signatures from the forensic analyst only.
• D. Only the final disposition and analyst initials.

Answer: (A)

Maintaining a chain-of-custody log is about creating a complete, auditable record of every handling and transfer of an evidence item to preserve its integrity. The best answer includes a unique item ID and description, the date and time of each event, who is currently responsible (custodian), who is receiving the item, and the purpose of the transfer, with signatures from every custodian involved in each transfer. This ensures there is a continuous, verifiable trail from collection to presentation in court, so any doubt about tampering or mishandling can be ruled out. Other approaches fall short because they omit key elements. Merely listing descriptive details like item name, color, or where it was found doesn’t document movements or accountability, and having only a lab supervisor sign leaves gaps where other custodians handled the item. Recording just the date/time of receipt or a form number tracks limited activity, not the full chain or purpose. Focusing only on final disposition and analyst initials loses the history of handling entirely, making it impossible to prove a continuous chain of custody.
