Dactylographic and dermatoglyphic characteristic of papillary fingerprint ridge patterns of serial killers who committed acquisitive crime

Abstract

In order to verify the conclusions made by other scholars that based on the traces of papillary ridges of fingers and hands using dermatoglyphic methods in forensics allow composing portrait of a suspect, the authors of the articled analyzed the dactylographic and dermatoglyphic characteristics contained in the accurate dactylographic profiles of the known serial killers who committed acquisitive crimes. Choice of this motive is explained by the fact that both males and females were driven by it. The subject of this research is the types of papillary fingerprint ridges, dactylographic formulas, pattern of ridges, presence or absence of symmetry of the same type of ridge on the same fingers of both hands, and delta index. Research methodology is based on the analysis of modern scientific provisions of dactyloscopy and dermatoglyphics. Considerable attention is given to the use of private scientific methods of cognition: description, comparison of characteristics of papillary fingerprint ridge patterns of serial killers. The application of these methods of cognition allowed concluding on the absence of undisputed evidence of papillary fingerprint ridge patterns of criminal nature, namely an increase in the number of arched ridges in calculating the frequency of ridges on separate fingers. This article is first to analyze not only the accumulated unique empirical material, but also presents the images for getting a fuller representation on the known serial criminals.
