Which of the following is NOT a method used in crime scene searches?

The approach used in crime scene searches is critical to ensuring that evidence is collected methodically and comprehensively. A grid search, spiral search, and zone search represent systematic methods employed to cover an area thoroughly and efficiently.

The grid search involves creating a grid over the area to be searched, allowing multiple teams to work independently along parallel lines. The spiral search consists of a single person starting from a central point and moving outward in a spiral pattern, which is especially useful in smaller crime scenes. The zone search divides the area into smaller zones, with each team assigned a specific zone to search, ensuring that no area is overlooked and that all potential evidence is gathered.

In contrast, a random search does not provide a structured framework for searching, which can lead to missing critical evidence or discrepancies in the search methodology. Random searching is chaotic and lacks systematic coverage, making it unsuitable for gathering evidence at a crime scene. Thus, labeling random search as not a recognized method aligns with the need for precision and thoroughness in forensics.
