 3D scanning technology has improved the ability of forensic pathologists to reconstruct crime scenes and obtain detailed information about wounds, traffic accidents, bullet trajectory studies, and bloodstain pattern analysis. A retrospective study conducted by the Department of Forensic Pathology at the University of Catania found that using a laser scanner, LS, in crime scene investigations allowed for faster and more accurate reconstruction of crime scenes, clarification of suicidal intent, and differential diagnosis between suicide and homicide. The LS was also useful in planning COVID-19 pathways and areas within a hospital to reduce nosocomial transmission. Overall, the use of the LS made it possible for forensic staff to crystallize the investigative scene and obtain valuable information for judicial purposes.
