Which search method involves moving in a circular fashion?

The spiral search method is characterized by its circular pattern, making it particularly effective in confined spaces, such as a room or a small outdoor area. This technique involves an investigator moving in a gradually expanding or contracting spiral pathway, allowing them to cover the entire area systematically. The method can be inward, starting from the outer edge and moving towards the center, or outward, beginning in the center and working towards the edges.

The spiral search is advantageous because it ensures thorough coverage without missing any evidence, as the investigator can adjust their path based on findings as they advance. This approach works well in situations where the search area is relatively small, and the investigator can maintain a constant distance from the center, increasing the likelihood of detecting hidden or subtle evidence. Ultimately, the efficiency and thoroughness of the spiral search method make it particularly suitable for many crime scene investigations.
