Which crime scene search pattern uses the grid approach to ensure area coverage?

• A. Grid
• B. Spiral
• C. Zone
• D. Line

Answer: (A)

Systematic coverage of a crime scene is achieved with a grid search pattern. In this approach, the area is overlaid with a grid, and investigators sweep each cell in one direction, then again in a perpendicular direction. This two-direction search creates overlap, reducing the chance of missing evidence and giving clear documentation of which portions were searched. It’s especially effective for larger or more complex scenes where thoroughness matters, because every section is examined methodically.

Other patterns—spiral, zone, and line—have different strengths: spiral starts at a center or edge and winds outward or inward; zone divides the area into defined sections searched sequentially; line uses parallel sweeps ideal for long, narrow spaces. The grid pattern best fits the goal of ensuring comprehensive area coverage through systematic, cross-direction searches.
