Which action is essential to maintain the integrity of DNA evidence during handling of potential sexual assault kits and DNA evidence?

• A. Preserve privacy
• B. Obtain consent when possible
• C. Document chain of custody
• D. Separate storage for evidence and notes

Answer: (C)

Maintaining the integrity of DNA evidence relies on documenting every transfer of possession through a chain of custody. This means keeping a precise, time-stamped, signed record of who handles the evidence, when, where it’s moved, and how it’s stored or sealed. This unbroken log proves that the item collected is the same one that appears in court and that it hasn’t been altered, contaminated, or substituted at any point. While privacy, consent, and separating storage are important considerations in handling sensitive cases, they do not by themselves establish the verifiable, auditable trail needed to demonstrate that the evidence remains unchanged from collection to presentation.
