Abstract: In this work we concern with identification Visible evidence that can only be observed with the naked eye and required for experiment of forensic scientist. the search details include many visible of physical properties that could be depend to explained many unknowns in crime scene which means critical truth for different cases. The details include appearance phenomena such color, smell, general shape, size, nature of material and predicted properties depending on general form.  The properties which mentions in the total work were reported here that could be enhance by using specific portable apparatus that could give very important information about the structure and nature with properties of evidence in crime scene.
