Quadrant/zone search: A search method in which the crime scene is divided into smaller sections (zones or quadrants) and team members are assigned to search each section. Each of these sections can be subdivided into smaller sections for smaller teams to search thoroughly.
What is zone method?
The zone method breaks the crime scene area into squares. For example, a living room can be divided into four equal sections and examined by an individual investigator. In many cases, those squares are further divided into additional, smaller squares to facilitate evidence location.
