What could be a disadvantage of the wheel search method?

The wheel search method is primarily designed for searching smaller areas where a specific object or piece of evidence is believed to be located. This method involves investigators starting from a central point and moving outward in a circular pattern, which can lead to less thorough coverage of the entire area. One of the main disadvantages is that if the object being searched for is located at the outer edges, it may be overlooked since the focus of the search is directed outwards from the center.

In contrast, other search methods, such as grid or zone searches, might provide better overall coverage, ensuring that no areas are missed. Therefore, while the wheel search can be effective in specific scenarios, its inherent design can lead to insufficient coverage, particularly in more complex or cluttered environments. This point underscores the importance of selecting the appropriate search method based on the nature of the scene and the evidence being sought.
