ABSTRACT
Every contact leaves a trace. As Agatha Christie pointed out, a crime is revealed by the various actions leading to the crime itself. This is because any action involves some type of contact that leaves traces. In other words, we all have heard that “there is no perfect crime.” It is all a matter of finding that revealing “trace,” which in legal terms is referred to as evidence. So, the generated traces provide the actual evidence that is absolutely required in legal proceedings and without which a criminal may never be charged with the crime, even if guilty. This is why it is essential to define the traces used to generate crime evidence.
