In criminal cases, the biological residues on bulletsshould be examined. In manycases, they may constitute aprecious evidence. The aim ofthis study is to show how it ispossible to gather evidencefrom biological residues. Inorder to achieve this purpose,we planned to fire test shotsat animal tissues and examine the bullets for residuesbelonging to the target.50 test shots were fired witha 7.65 mm semi-automaticpistol. In some of these testshots, calf spleens wereused as targets. The bulletsobtained were coded. Subsequently, the bullets wereexamined without knowledgeof whether they had hit themark or not. The aim wasto correctly guess those thathad hit the mark. To thisend, a commercial kit namedBluestar, which is a Luminolderivative, was used.After the application of Luminol, all the bullets showedblue luminescence in a darkenvironment. False positivities could have resulted fromgunpowder remnants or themetal of the bullet. In orderto eliminate the false positivities, the study should berepeated with equipment capable of measuring the emission intensity and spectrumof Luminol or with tests otherthan the Luminol test. </p
