Which of the following is NOT a crime scene search pattern?

The option identified suggests that the circular search pattern is not recognized as a standard crime scene search pattern. In crime scene investigation, search patterns are crucial for ensuring thorough and systematic evidence collection. The most commonly used patterns include zone (or grid), stripe (or line), and spiral, each serving distinct advantages depending on the scene's layout and the investigators' goals.

The zone search pattern involves dividing the crime scene into specific sections or zones that can be searched thoroughly, ensuring that every area is covered without overlap. The stripe or line pattern organizes investigators into a straight line to move across the scene in one direction, which is particularly effective in large outdoor areas. The spiral method, whether inward or outward, allows investigators to start from a central point and search systematically toward the perimeter or vice versa, making it suitable for smaller or more confined environments.

The circle search pattern is less conventional and not widely recognized in the same way as the others. It may lack the systematic coverage that the other established methods provide. Consequently, it is seen as an option that does not fit within the standard practices of crime scene investigation, thereby justifying its selection as the response that identifies a non-existent crime scene search pattern.
