How should trace evidence be preserved at a death scene?

• A. Avoid covering the body and restrict access to the area where the body is located.
• B. Cover the body with a sheet to protect it.
• C. Move the body to a secure location.
• D. Dust the area for clues.

Answer: (D)

Preserving trace evidence means keeping the scene exactly as it is and preventing contamination or disturbance of tiny clues. The moment a death scene is secured, the priority is to limit who can enter and to avoid touching or moving items unnecessarily, so fibers, hairs, prints, and other trace materials remain in place for proper collection later. Dusting the area for clues is not a preservation step—it’s an evidence-collection action that can smear, remove, or contaminate trace evidence, undermining the integrity of the scene. The goal is to minimize disturbance and document everything so trained investigators can collect evidence with the correct tools and procedures after the scene is secured. Covering the body with a sheet can be used to protect the scene from environmental factors and help maintain integrity, but the overarching principle is to prevent disturbance and preserve what’s there until proper collection occurs.
