Which criminal justice professional is responsible for collecting evidence from a crime scene?

• A. Detective
• B. Paralegal
• C. Forensic scientist
• D. Private investigator or detective

Answer: (D)

Collecting evidence at the scene is done by investigators who are trained to secure the area, document the scene, gather physical traces, and preserve a proper chain of custody for court use. In practice, this on-site role is handled by detectives or crime scene investigators within law enforcement. The option that includes private investigator or detective reflects this real-world duty—the detective is the traditional on-scene investigator who collects and preserves evidence. Private investigators may conduct field work as well, but they typically operate privately and lack official authority on crime scenes in many jurisdictions. Paralegals support legal teams and do not collect crime-scene evidence, while forensic scientists focus on analyzing evidence in the lab rather than collecting it at the scene. So, the choice that encompasses the on-site investigator role best matches who is responsible for collecting evidence from a crime scene.
