Name four standard crime scene search patterns.

Name four standard crime scene search patterns.

• A. Random search.
• B. Spiral search only.
• C. Grid, strip/line, zone/sector, and circular searches.
• D. Grid, strip/line, spiral, and zone/sector searches.

Answer: (D)

Systematic crime scene searching relies on patterns that ensure thorough, repeatable coverage of the area so nothing is missed. The four standard patterns are grid, strip/line, spiral, and zone/sector. A grid search uses overlapping passes in two directions, usually perpendicular, to maximize coverage and catch tiny or overlooked evidence. A strip or line search moves in parallel passes in a single direction, which is fast and efficient for large, open spaces or outdoor scenes. A spiral search starts at a point and moves outward (or inward) along a continuous spiral, which works well in open interiors where you can follow a single path. A zone or sector search divides the scene into defined areas assigned to teams or individuals, making it practical for large or complex scenes and helping manage time and resources. These patterns collectively provide versatile, structured approaches that adapt to different layouts and conditions, which is why they are the standard set to name four. Random searching and patterns limited to only spiral or other single methods risk gaps in coverage and are not considered standard practice.
