What is the proper approach to preserving a crime scene?

• A. Secure the area, limit access, document conditions, and prevent contamination or alteration
• B. Document background
• C. Interview witnesses
• D. Post signs

Answer: (A)

Preserving a crime scene means keeping evidence in the same condition it was found so its integrity remains intact for investigation and court use. The best approach is to secure the area, limit access to essential personnel, document the scene’s initial conditions, and prevent contamination or alteration. Securing and restricting entry prevents additional changes and new evidence from being introduced, while recording how the scene looked at first ensures you have an accurate baseline for later analysis. Handling evidence carefully and following proper collection procedures further protects its integrity.

Other tasks like documenting background information or interviewing witnesses are important parts of the investigation, but they should occur after the scene has been secured and preserved. Posting signs alone helps with general control but does not properly preserve the scene if access isn’t still limited or conditions aren’t documented.
