Police must secure which type of evidence?

• A. Digital evidence only.
• B. Eyewitness testimony.
• C. Circumstantial evidence.
• D. Physical evidence due to the serious nature of the crime.

Answer: (D)

Securing physical evidence at a crime scene is essential because tangible items can be scientifically tested and linked to events or people in objective ways that memories or statements cannot. Officers protect the scene, limit access, and maintain a strict chain of custody to prevent contamination and ensure the evidence remains admissible in court. While digital evidence, eyewitness accounts, and circumstantial evidence all have roles, physical evidence is the foundation of most investigations, especially for serious crimes, because it yields concrete, verifiable data such as fingerprints, DNA, weapons, and trace materials.
