Abstract

A tanulmány az ujjnyomatszakértői és a nyomszakértői szakterületek kompetenciahatárait és az esetleges egyesített szakvélemények lehetőségét mutatja be. A két szakterület kompetenciáinak normatív és rövid gyakorlati bemutatását követően olyan esettanulmányokat ismertet, ahol a nyomszakértő a daktiloszkópiai azonosításra alkalmatlan nyomokat az azonosítás magasabb szintjeire tudta emelni. A jövőben lehetséges együttműködési területté válhat a daktiloszkópiai nyomok tevékenységszintű értelmezése, illetve a tenyerek redőinek és ráncainak felhasználása az azonosításban. | This study explores the interface and collaborative potential between two branches of forensic science: latent print and pattern evidence analysis. It compares their normative boundaries and practical competencies and introduces real-life case studies where palm or hand prints were deemed unsuitable for ridgeology identification, but were successfully evaluated by mark experts. These examples demonstrate how activity-level interpretation and morphological analysis of palms can complement source-level identifications traditionally performed by fingerprint experts. The paper analyzes differences in methodology and interpretation: while dactyloscopy typically offers categorical conclusions based on the minutiae of the ridges, mark experts use a probabilistic five-tier scale and can perform reconstructions to interpret the mechanism of pattern formation. These different perspectives enrich forensic conclusions, especially in the analysis of complex crime scenes, involving bloodstained or smeared prints. The authors review relevant Hungarian legislation, which defines the forensic expert competence domains, and point out interpretational and procedural ambiguities, such as whether barefoot or gloved palm impressions fall under one or both areas of expertise. Several case examples are discussed where traditional ridgeology methods failed due to poor print quality, but subsequent impression analysis yielded significant evidence – either by narrowing down potential sources or by reconstructing actions at the crime scene. These include violent crimes where palm traces helped validate or refute testimonies or establish victim-suspect positioning and interactions. Particular attention is paid to the structure and forensic utility of major, minor, and secondary palm creases. The study also highlights the significance of expert collaboration and thorough scene documentation in ensuring that latent and seemingly “useless” marks are appropriately interpreted. The authors advocate for a broader forensic awareness of these hybrid cases and suggest that such cross-disciplinary cooperation can improve identification outcomes and the evidentiary value of pattern evidence.
