Abstract

In recent years, advancements in technology have led to the development of more sophisticated techniques for analyzing and comparing bullet striations. These techniques can be used to match a bullet found at a crime scene to a specific firearm with a high degree of accuracy, which can be valuable evidence in criminal investigations. In criminal assault, prevalence or frequencies with which firearms are used has resulted in the development of advanced aspects of criminalistics. Collection of firearms evidence can be classified based on the collection of ammunition, firearms and gunpowder obtained from the scene of crime. Hence for the identification purpose, multipleapproaches are being used such as trace metalcompositionalong with simultaneous comparison or matching of striation marks on bullets. These impressions or striations are like fingerprints of a bullet or a firearm and are unique to the firearm from which it was fired from. Recently, the most reliable instrument used for identification is the comparison microscope, Scanning Electron Microscopy. Once the images of striation are obtained using the SEM, it is then compiled using software like Amira-Avizo or for automated compiling and is transferred to VR. Thus, VR can be used for closer inspection by an expert. The following paper thus goes through the scope, analysis, and the advancements of striation markings on the bullets from traditional to modern techniques and its use in the field of forensic ballistics. This would highly help in increasing the reliability and the accuracy of bullet matching in forensic ballistic cases
