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

• A. Ignoring transfer documentation if the item is digital.
• B. Maintaining an unbroken record of who handled the item, when, and why.
• C. Allowing any individual to access evidence without logs.
• D. Recording custody only after evidence is released to the client.

Answer: (B)

Maintaining a chain of custody ensures an unbroken record of who handled the item, when it was transferred, and why the transfer occurred. This keeps the evidence's integrity intact and supports its authenticity, showing it hasn’t been tampered with or altered from collection to presentation. By documenting every handoff, access, and purpose, it creates accountability and helps prevent disputes about how the evidence was managed.

The description of an unbroken record of handlers, timestamps, and reasons for custody changes is the best fit because it directly captures the ongoing control and provenance of the item. In contrast, ignoring transfer documentation—even for digital items—undermines integrity; allowing anyone to access evidence without logs defeats accountability; and recording custody only after release to the client misses all the important custody during the investigation and prior to final disposition.
