Types of searching when scanning a crime scene include:

• A. Grid
• B. Spiral
• C. Zone
• D. All of the above

Answer: (D)

When scanning a crime scene, investigators use systematic search patterns to cover the area thoroughly. A grid search involves moving in parallel lines across the scene with overlapping passes, providing dense coverage and clear documentation of what was checked. A spiral search starts at a point and proceeds in a continuous spiral outward (or inward), which is useful for concentrating on a central area or avoiding backtracking in cluttered spaces. A zone search divides the scene into defined sectors, with a team member responsible for each zone, helping manage large or complex areas and maintain organization and evidence custody. Because each pattern serves different scene characteristics and investigative needs, all of these methods are valid approaches. The correct takeaway is that all of the above are types of searching used when scanning a crime scene.
