Despite that modern tools provide 3D reconstruction of real crime scenes, the analysis of the events is often a result of manual measurements from experienced personnel. In this study, AI and Computer vision-based methods, integrated in a 3D VR crime scene, are introduced to automatically determine the trajectory of bullets and the origin of bloodstains. These methods enable the precise analysis of bullet holes and bloodstain patterns on surfaces, providing essential insights for forensic investigation. This innovative approach combines practical, hands-on experience with advanced analytical methods, offering a comprehensive tool for analyzing crime scenes and supporting law enforcement personnel in their duty.
