Abstract

The article examines the technical foundations of forensic residuography and its medico-legal and criminalistic application. The exposition conceptualizes residuography and forensic residuograms, distinguishes the non-metallic and metallic types and analyzes the chemical composition of ammunition cartridges, with emphasis on the initiating and propelling charges and on the alloys of projectiles and jacket coatings. The investigation examines residuographic tests of criminalistic interest, the estimation of shooting distance and angle, the differential diagnosis between homicide and suicide and the techniques for removing particles. The text concludes that expert reports require rigorous interpretation and safe conclusions.
