Which statement best describes the spiral search method used by investigators?

• A. A continuous motion outward from a central point
• B. A grid-based, line-by-line sweep
• C. A vertical scan of the ceiling to floor
• D. A random wandering pattern

Answer: (A)

A spiral search method starts at a central point and moves outward in a continuous outward curve, tracing a widening circle around the center. This creates systematic coverage so every area near the center is revisited and the outer edges are reached without leaving gaps, making it efficient for locating evidence around a focal point without retracing large sections. It differs from a grid-based line-by-line sweep, which follows straight strips and can be slower and may miss spots between lines if not executed perfectly. It isn’t a vertical ceiling-to-floor scan, which focuses on height rather than planar area, and it isn’t random wandering, which lacks a predictable path and can miss relevant spots.
