Which practice supports the preservation of evidence integrity?

• A. Releasing evidence to the public
• B. Altering records to fit a narrative
• C. Randomly redistributing evidence to confuse investigators
• D. Maintaining proper chain of custody and documenting handling

Answer: (D)

Preserving evidence integrity hinges on maintaining an unbroken chain of custody. This means the item is tracked from collection through storage to presentation, with clear documentation of who handled it, when, where, and how it was stored, and ensuring it remains in the same condition as when found. Proper chain of custody and handling documentation prevents tampering, loss, or misidentification, and supports the reliability and admissibility of evidence in investigations or court. Releasing evidence to the public, altering records, or randomly redistributing evidence would undermine control, create opportunities for tampering or confusion, and expose officers to legal liability. Implementing this practice includes secure storage, tamper-evident seals, restricted access, and detailed log entries.
