What is a common search pattern used in investigations?

The spiral search pattern is commonly used in investigations, particularly in fire and crime scene investigations. This method involves the investigator starting from a central point and making a continuous outward spiral or an inward spiral toward the center. The primary advantage of the spiral pattern is that it allows for a thorough examination of the area, ensuring no evidence is overlooked while systematically covering the entire scene.

This pattern is especially effective in scenes where there is a specific focal point, such as the origin of a fire. By maintaining a consistent distance from the center, the investigator can ensure that all areas are searched in an organized manner, helping to establish a clear understanding of the scene's layout and potentially revealing crucial evidence. The method is adaptable to different environments, whether it be indoor or outdoor, making it a favored technique in various types of investigations.
