Which evidence is often found in environments like snow or sand?

Impression evidence is commonly found in environments like snow or sand because these materials can easily retain and display the unique patterns and shapes that objects leave behind when they make contact with the surface. When a footstep, tire track, or tool mark is pressed into the soft surface of snow or sand, the impressions capture detailed characteristics that can be used for identification purposes.

This type of evidence plays a crucial role in criminal investigations, as it can link a suspect to a crime scene or provide insights into the actions that took place. The ability to collect and analyze these impressions is essential for law enforcement agencies to establish a connection between the scene and the individuals involved.

In contrast, the other types of evidence listed do not typically pertain to the characteristics associated with environments like snow or sand. Documentary evidence involves written records and is not affected by environmental conditions in the same way. Digital evidence is concerned with information stored on electronic devices, which would not be present in natural settings like snow or sand. Latent fingerprint evidence requires non-porous surfaces to collect distinct finger patterns, making its presence in snow or sand unlikely. Thus, the focus on impression evidence is key when considering the types of evidence that can be effectively gathered in such environments.
