Which of the following best describes evidence that is difficult to find in a grid search?

The choice that best describes evidence that is difficult to find in a grid search is evidence that may be hidden and requires thorough inspection. In a grid search, investigators systematically divide a large area into smaller sections to ensure that no evidence is overlooked. However, certain types of evidence, especially those that are small, obscured, or camouflaged within the environment, can easily be missed without careful and detailed examination.

This is particularly true for items that are not readily visible or that blend into their surroundings, making them challenging to locate even with a methodical approach like grid searching. The focus on thorough inspection emphasizes the need for diligence in searching for hidden evidence to ensure a comprehensive investigation.
