Forensic DNA analysis can be a useful tool in aiding forensic identification because DNA is found in almost all cells of our bodies except mature red blood cells. Deoxyribonucleic acid is located in two different places of the cell, the nucleus; which is inherited from both parents, and the mitochondria; inherited maternally.
Body identification is a subfield of forensic science that uses a variety of scientific and non-scientific methods to identify a body. Forensic purposes are served by rigorous scientific forensic identification techniques, but these are generally preceded by formal identification. [ 1 ]
The case would be decided in favor of the individual with the best argument and delivery. This origin is the source of the two modern usages of the word forensic—as a form of legal evidence; and as a category of public presentation. [6] In modern use, the term forensics is often used in place of "forensic science."
DNA marking is a type of forensic identification. It is a method to mark items in a way that is undetectable to the naked eye. A unique DNA marker is applied to the item, and can be recovered to identify the item. In suspected thefts, the suspect can also be tested for traces of the DNA marking. [1]
Developed in 1991, [10] DQ alpha testing was the first forensic DNA technique that utilized the polymerase chain reaction. [11] This technique allowed for the use of far fewer cells than RFLP analysis making it more useful for crime scenes that did not have the large amounts of DNA material that was previously required.

Brian E. Dalrymple is a Canadian fingerprint scientist known for introducing the use of lasers (with colleagues Duff and Menzel) as a forensic light source for fingerprints and other evidence detection, using the Argon Ion Lasers to detect the inherent fluorescence of the latent fingerprints and finding fluorescing evidence.

The International Fingerprint Research Group (IFRG) is forensic identification researcher group that gather together to exchange scientific knowledge in forensic identification. The IFRG is regrouping the most active researchers in the world in the forensic identification field and was founded in September 1974.
