Common search patterns include the spiral, strip/line, grid, zone/quadrant, and pie/ wheel. The spiral search is used most often for outdoor crime scenes, is conducted by one person, and is done by walking in a circle from the outermost point of the inner perimeter toward the center of the circle.
What is Zone search 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.
What type of crime scene search pattern should be used to properly search inside the house?

When this type of search pattern is used, an investigator is able to comb the area for blood spatter origins and directionality patterns.

What are four steps used to analyze a crime scene?
What are the 4 steps to analyze a crime scene?
- Approach the Scene.
- Secure and Protect the Scene.
- Initiate Preliminary Survey.
- Evaluate Physical Evidence Possibilities.
- Prepare a Narrative of the Scene.

What is quadrant or zone search?
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 the zone pattern?
The zone search: In a zone search, the CSI in charge divides the crime scene into sectors, and each team member takes one sector. Team members may then switch sectors and search again to ensure complete coverage.
What is quadrant or zone method?
The Zone or Quadrant search is a method in which the crime scene is divided into smaller sections and team members are assigned to search each section. Those sections can be subdivided into smaller sections for smaller teams to search thoroughly.
