INTRODUCTION: Often in forensic practice at the crime scene are observed specific traces of biological material (usually blood) from incriminated objects associated with offenders or victims. Sometimes such traces remain of objects with specific shape of the surface, enabling their identification. Therefore a comparison analysis is needed between the object and the traces it had left. We present a case of homicide with a blunt object where two homeless men quarreled, one of them inflicted multiple hits to the other that led to dead and left the crime scene afterwards. MATERIALS AND METHODS: Crime scene investigation. Complete forensic examination of the trace evidence with experimental comparing. RESULTS: The deceased was found on a linoleum floor covered with blood. On the pieces of linoleum from the crime scene provided by the police we discovered numerous traces of blood forming complex line-ups appearing as slurs, elements of wiping, blood splatter, as well as partial prints with specific shape consisted of elements with stable configuration, without superimposing static or dynamic overlays or alterations. DISSCUTION: The analyses of the specific prints on the linoleum led to the conclusion that they were from shoe soles. The shoes of the suspect were analyzed. Crime scene and experimental traces were photographed and with the help of Adobe Photoshop ® the images were superimposed. After unification of their scales and software processing a matching between parts of the grapple pattern of the shoe sole of the left shoe of the suspect and the specific blood prints on the linoleum was discovered.
