Pirštų ir pėdų odos papiliarinių linijų raštų charakteristikos daktiloskopijos tyrimo kontekste

Abstract

The material world is characterized by the interconnectioness and conditionality of phenomena. Every crime affects various objects in the external world and causes changes in the environment. In criminology, all these material influences and changes are called “crime traces”. Since crime traces are not homogeneous, they are investigated by several branches of forensic science techniques. An important part of the trace investigation belongs to the field of trassology. The trassology branch which studies the structure and properties of the papillary ridge patterns and the use of its traces in evidence is called dactyloscopy. When examining an object or a crime scene, investigators often find fingerprints, sometimes palm prints, and less frequently barefoot prints, which display papillary ridge patterns. The author hypothesizes that the papillary loop and whorl ridge pattern on the corresponding toes and fingers of the same-sided hand and foot pairs have statistically significant similarities. If matching patterns are detected, the number of papillary lines from the delta to the center of the same type of papillary patterns will be counted. This process involves an examination of the general characteristics that are part of the trace verification process when identifying a person. The general features characterize both the external and internal features of the ridge pattern. The lines in the center of the trace indicate the classification type, species, or special category to which the trace belongs. This knowledge is important both for crime scene investigators working at the scene of a crime and for experts in the field conducting forensic examinations.
