Not a listed form of evidence term?

• A. Perishable
• B. Shadow
• C. Impression
• D. Transfer

Answer: (B)

In investigations, certain terms describe the way evidence exists or is collected. Perishable evidence refers to items that decay or lose value quickly, so they require prompt handling and proper preservation. Impression evidence covers physical marks or imprints left by objects, such as footprints, tool marks, or tire treads. Transfer evidence describes material that has moved between surfaces or people through contact, which helps establish connections and support the chain of custody. Shadow, however, is not a recognized form of evidence terminology describing how evidence is categorized or collected. It’s not used to label evidence types in standard practice, so it wouldn’t be listed among formal evidence terms.
