When processing a crime scene, in what order should layers be searched?

From bottom to top
In random order
In a systematic order from surface to deeper layers
By size of the evidence collected

The correct answer is: In a systematic order from surface to deeper layers

The correct approach to processing a crime scene is to conduct a systematic search from the surface to deeper layers. This method is essential because evidence may be layered or concealed under other materials, such as dirt, debris, or vegetation. By starting at the surface, investigators can collect evidence that might have fallen or been left on top before disturbing any underlying layers. This careful and methodical approach helps ensure that crucial evidence is not overlooked or contaminated, which could hinder an investigation. In addition, searching systematically allows for a thorough examination of each layer, making it easier to document findings accurately and maintain the integrity of the evidence. This is important not only for the investigation but for subsequent legal proceedings, as it demonstrates adherence to proper forensic procedures.
