Técnicas de identificación de revelado en huellas dactilares latentes, dentro del rol perito químico forense en la escena del delito

Abstract

The importance of identifying a person who participates in a criminal act, where latent prints are produced by the pad of the finger stained with ink, sweat, or other liquid on a flat surface, which presents a variety of different images, which provides its use for identification purposes. The forensic chemical expert applies the deductive method, which reaches the knowledge of general truth to a particular one, within the area of the IoT (Technical Ocular Inspection), where the crime scene is predetermined in protecting, observing, searching, fix, lift, to transport the footprint or papillary trace. The objective of this work was to evaluate identification techniques in the development of fingerprints through the scientific contributions applied in fingerprints to use effective methods within the role as forensic chemical expert, to use a methodology that reduces and avoids errors, within his participation as an expert in the revelation of latent prints. In which we conclude that one of the first fields of criminal investigation was lofoscopy, the forensic chemical expert applies the fingerprint identification technique that will scientifically solve the problems derived from crime, being the best known and applied science for the identification of a person, using within the automatic fingerprint identification system, allowing the expert to control the coincidence of the characteristic points between the doubted elements (trace found at the scene of the event), with the undoubted element (trace commissioned in the database).
