Forensic science involves many different disciplines including alcohol, anthropology, chemistry, document identification and forgery, entomology, fingerprints, firearms, trace evidence, odontology, biology and pathology (to name a few). Professionals in these fields use the latest technology and research to assist the legal system to determine a suspect’s guilt or innocence.

A piece of evidence found at the scene of a crime will often be analyzed by several different methods to get the most information from it. For example, a shoe may be examined for bloodstains (studied by biology, DNA analysis), trace evidence (broken glass or similar type of dirt found on suspects shoe and crime scene), gunshot residue (may be on suspect’s clothes or hands as well) etc. A person or persons at the scene when a crime is committed will almost always leave something behind and take something away with them.
