Which of the following best describes evidence preservation at the scene?

• A. Move items to base station
• B. Wait for investigators to act
• C. Coordinate with investigators
• D. Avoid moving items unnecessarily; document with photos, maintain chain-of-custody for any collected items

Answer: (D)

Preserving evidence at the scene means keeping items in their original places as much as possible so nothing is altered or contaminated. The best approach is to avoid moving items unnecessarily, document the scene with photographs and notes before touching anything, and maintain a clear chain-of-custody for any items that are collected—recording who handles them, when, and how they’re stored. Coordinating with investigators is important for a coordinated response, but it doesn’t replace the need to prevent disturbance and to create reliable documentation. Waiting passively or moving items to a base station can compromise evidence integrity. So, minimize disturbance, document thoroughly, and ensure proper custody of any evidence.
