What is the primary purpose of preserving evidence at a crime scene?

• A. To expedite the investigation.
• B. To weaken integrity and allow contamination.
• C. To maintain integrity and prevent deterioration or contamination.
• D. To confuse witnesses.

Answer: (C)

Preserving evidence at a crime scene is about keeping it in its original, untampered condition so it can be accurately analyzed later and the sequence of events can be reconstructed. This means protecting its integrity, preventing deterioration, and avoiding contamination, while also maintaining a clear chain of custody and proper documentation. If evidence is altered, damaged, or contaminated, forensic results may be unreliable and the investigation compromised. Expediting the process or attempting to contaminate the scene would undermine the value of the evidence, and confusing witnesses isn’t the aim.
