Forensic science represents the unification of different scientific disciplines with the final outcome of establishing the truth in the sense of the criminal justice. It's application in international investigations of war crimes, crimes against humanity and genocide, as the primary goal in identifying those responsible, is underrepresented. From a historical, legal and humanitarian point of view the contribution is invaluable, yet the large financial resources required for multidisciplinary implementation in investigations of serious human rights violations, which are on the rise in the world, limit its use. Many forensic experts voluntarily join various international organizations to document extrajudicial executions and torture, persecution, genocide, in order to present evidence that the court can use to reveal the identity of those in power who directly or decisively approved the crime committed. Although their task is not to identity the people violating of fundamental human rights, the forensic evidence gathered is of primary importance in the process of establishing responsibility and identifying victims, and thus also serves as a warning in preventing further crimes. Precise and high-quality documentation that is impossible to realize without the involvement of experts in certain disciplines, not only ensures scientifically irrefutable confirmation or challenge of other evidence, but significantly contributes to providing important elements needed to reveal the identity of victims. Ultimately, although a secondary goal, there is no doubt about the importance of the humanitarian part, which ultimately provides the most important thing, the dignity of the deceased.
