Abstract

In criminal cases, the biological residues on bullets should be examined. In many cases, they may constitute a precious evidence. The aim of this study is to show how it is possible to gather evidence from biological residues. In order to achieve this purpose, we planned to fire test shots at animal tissues and examine the bullets for residues belonging to the target. 50 test shots were fired with a 7.65 mm semi-automatic pistol. In some of these test shots, calf spleens were used as targets. The bullets obtained were coded. Subsequently, the bullets were examined without knowledge of whether they had hit the mark or not. The aim was to correctly guess those that had hit the mark. To this end, a commercial kit named Bluestar, which is a Luminol derivative, was used. After the application of Luminol, all the bullets showed blue luminescence in a dark environment. False positivities could have resulted from gunpowder remnants or the metal of the bullet. In order to eliminate the false positivities, the study should be repeated with equipment capable of measuring the emission intensity and spectrum of Luminol or with tests other than the Luminol test.
