In the following main forms of trace evidence is that most forensic scientist; center on such as fiber, hair, glass, condom, shoe and tire impressions will be covered and discussed in how they may give help to both investigators and prosecutors.
Edmond Locard, one of French scientist of the early pioneers in forensic science that strongly believed that individuals could not enter an area without taking dust particles with them from the scene. “Locard believed that crimes could be solved by inspecting the
