Question

Quizplus · Accepted Answer

The Locard Exchange Principle states that every contact, whether between two people or between a person and an object, leaves a trace. This is a fundamental principle in forensic science and is used to link suspects to a crime scene or to each other. Option A is incorrect because many crimes can be committed by a single person, while option C is not directly related to the Locard Exchange Principle. Option D is somewhat related to the principle, but it is too narrow in scope. The Locard Exchange Principle covers all types of contact, not just the transfer of evidence from the scene to the lab.
