In forensic ballistics, the perforation of glass by a bullet leaves characteristic marks, such as radial and concentric fractures and cones, which are crucial for reconstructing the bullet's trajectory and the shooting scene. Traditionally, digital forensic photography has been used to document these distinct characteristics. This research compared the ability of experts and trainees to accurately assess the directionality of bullets shot through vehicle windshields using photography and two innovative approaches: l) paper and pencil to create a frottage and 2) latent print powder and gel lift. Two vehicle windshields were shot six times, from the outside and the inside, by two different types of ammunition. The inside and outside of each bullet hole was documented via the three methods. The documentation for each bullet crater was blindly presented to experts and novices to assess their accuracy determining entry versus exit. The two innovative approaches of paper and pencil method and gel lift method produced higher accuracy for both experts and trainees when compared to traditional photography. Furthermore, there was no significant difference in accuracy of the experts and novices. This work aims to contribute to the ongoing refinement of forensic ballistics methodologies, enhancing the precision and reliability of evidence collection in the field.
