What does the Theory of Transfer state?

• A. It describes how evidence never moves
• B. It states that weather affects evidence only
• C. No one can enter a location without bringing something into the area and leaving some trace behind, and no one can exit a location without taking some trace away.
• D. It only concerns digital evidence

Answer: (C)

The Theory of Transfer is about exchange that occurs when people come into contact with a location. When someone enters a scene, they bring in materials from outside and leave behind traces from the scene already there. When they leave, they take traces with them. This idea—that contact results in a measurable transfer of material—underpins how investigators search for and interpret trace evidence like fibers, hairs, skin cells, footprints, and other clues. It applies to all types of evidence, not just digital. The other options don’t fit because evidence can move, weather isn’t the defining factor, and the theory isn’t limited to digital evidence.
