Which of the following is not a listed search pattern?

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

Answer: (C)

In systematic crime scene searches, investigators use predefined patterns to cover the area without gaps. Grid/strip and line are straight-line approaches that sweep the space in organized directions, ensuring thorough coverage. Zone divides the scene into defined areas so teams can work methodically in each section. Spiral is a circular approach that starts at a point and moves outward (or inward) to ensure complete coverage around a center.

Circle, as a standalone pattern, isn’t a standard listed pattern because it doesn’t by itself guarantee full coverage. When a circular path is used, it’s typically described as a spiral search, which actually provides the intended expanding or contracting coverage. Therefore, circle is not a listed search pattern.
