Study of the Influence of External Conditions and Materials on the Preservation of Hidden Prints under Water

Concealment of a crime involves a number of processes that the guilty person performs to destroy their own fingerprints, including immersing or flooding the objects of illegal acts. That is why the expression of the influence of the water environment, its features and external conditions on the preservation of evidence of a crime is an urgent issue. The purpose of the article was to study temperature, time, chemical features of water resources and other factors for the possibility of qualitative detection and research of human fingerprints on various types of materials. In the work, the author independently conducted an experiment that formed its methodological basis. As a result of the conducted research, it was established that the examination of evidence, including fingerprints under water, was an important component of the investigation of the crime.
