Which statement correctly lists the four search patterns described?

• A. Grid/strip, Line, Spiral
• B. Line, Spiral, Zone
• C. Zone, Circle, Grid
• D. Grid/strip, Line, Spiral, Zone

Answer: (D)

The four standard search patterns used at crime scenes are grid/strip, line, spiral, and zone. Grid/strip involves sweeping the area with parallel passes over a two-dimensional space, which maximizes coverage in open areas. Line search has investigators moving along straight lines, making it efficient for long, open or clearly bounded spaces. Spiral search moves in a circular path either from the outside toward the center or the center outward, ensuring continuous coverage around a point of interest. Zone search divides the scene into sections, with each zone searched thoroughly by a team, which helps manage cluttered or complex areas.

The option listing all four patterns—Grid/strip, Line, Spiral, Zone—is the correct one. The other options either omit a pattern or replace one with Circle, which isn’t part of the standard four described here.
