What practices help maintain the integrity of physical evidence?

• A. Never document transfers.
• B. Proper packaging, labeling, sealing, securing; maintain chain of custody; document.
• C. Conduct sequential destruction after analysis.
• D. Store items in any container without labeling.

Answer: (B)

Maintaining the integrity of physical evidence depends on how the item is handled from collection to presentation. Proper packaging protects the evidence from damage and cross-contamination, while clear labeling ensures you know exactly what the item is and where it came from. Sealing creates a tamper-evident boundary so you can tell if someone has opened or altered the item after it was collected. Securing the item means placing it in a controlled, access-limited environment to prevent loss or tampering. Crucially, the chain of custody provides a documented trail of every person who handled the item, along with dates, times, and reasons for transfer. This record shows the item’s history and helps establish its authenticity and reliability in court. Finally, thorough documentation ties all the steps together so the evidence can be tracked, defended, and admitted properly. Without these practices, evidence can be contaminated, tampered with, lost, or misidentified, and its admissibility can be jeopardized.
