Which crime scene search pattern begins at the perimeter and moves toward the center?

• A. Grid
• B. Parallel
• C. Inward Spiral
• D. Zone / Sector

Answer: (C)

Crime scene search patterns are ways investigators systematically cover an area to ensure all spaces are examined and evidence is documented. The inward spiral starts at the outer boundary and sweeps in toward the center, creating a continuous path that ensures the perimeter is checked first and no area is left unexplored along the edges. This approach helps avoid missing spots on the outer limits and reduces backtracking, which is especially useful when the scene has defined edges or a complex interior. Other patterns work differently: a grid uses overlapping straight passes in two directions for thorough cross-checking; parallel moves investigators along straight, parallel lines, which is efficient for large open areas; and zone or sector divides the scene into defined sections assigned to teams. The inward spiral is chosen specifically because it begins at the outer edge and moves inward, guaranteeing edge coverage before converging on the center.
