Which statement about circle or spiral search patterns is accurate?

• A. They include a shrinking circle and expanding circle
• B. They only apply to indoor scenes
• C. They are used only for documentation
• D. They are described as narrowing circle and widening circle

Answer: (D)

Circle or spiral search patterns are described by how the search area is progressed. The accurate description is that they involve a narrowing circle and a widening circle, which captures the idea of moving toward a center or outward from a center in a systematic sweep. This approach ensures thorough coverage of the scene and provides a clear, repeatable method that can be documented for reconstruction. These patterns are applicable to both indoor and outdoor scenes and are about locating and recovering evidence, not just documenting it. While shrinking/expanding convey a similar idea, the standard terminology emphasizes narrowing and widening to describe the direction of the search progression.
