Some bullets, called tracer and API bullets, contain a pyrotechnical charge. The charge in the bottom of a tracer bullet burns in flight and enables the shooter or an observer to see the bullet's trajectory. An Armor Piercing Incendiary (API) bullet contains a hard core and a pyrotechnical charge that ignites on impact with a hard target.

Since the release of the first 3D-printed firearm, "The Liberator," the occurrence of 3D-printed firearms in criminal activities has increased, highlighting the need for forensic research on these weapons. This study presents a technical examination of a 3D-printed firearm received by the National Institute of Criminalistics and Criminology (NICC), focusing on its design, ballistic performance, and its potential for microscopic comparative analysis. The firearm, resembling a 3D-printed pistol Yeet22, is primarily constructed from polymer parts, with the exception of the firing pin, barrel, and various springs and screws.

: Firearm wounds tend to have a precise pattern. Despite this, real-world case presentations can present uncertain elements, sometimes deviating from what is considered standard, and present uncommon features that are difficult for forensic pathologists and ballistic experts to explain. : A retrospective analysis of autopsy reports from the Institute of Legal Medicine, University of Catania, covering 2019-2023, included 348 judicial inspections and 378 autopsies performed as part of the institute's overall activities.

In shooting incident reconstructions, forensic examiners usually deal with scenes involving short-range trajectories, typically ≤30 m. In situations such as this, a linear trajectory reconstruction model is appropriate. However, a forensic expert can also be asked to estimate a shooter's position by reconstructing a long-range trajectory where the bullet's path becomes arced as a result of gravity and the greater time in flight.

Firearm-related scenarios can be highly complex, involving multiple shooters, firearms, types of ammunition, victims, and various impact zones. Obtaining the maximum amount of information to connect each piece of the puzzle is crucial for resolving these cases. Currently, new tools are being developed in the forensic field that facilitate both fieldwork and laboratory analysis, enabling the estimation of trajectories, identification of shooters, and more.
