Physical evidence has the potential of linking the crime and the victim or the perpetrator. It plays of identification, it determines the physical and chemical identity of a substance with certainty as far as analytical method would permit. It also plays the role of comparison, it compares a standard and suspect samples from a crime scene and determines if they all have a common origin. It provides the main elements of the crime and it proves the theoretical aspects of the case. It can also be used during interrogations of suspects (Brandl, 2014).
