• Abstract:

  The ballistic confrontation exam is one that, when carried out, establishes correlations between ammunition elements and firearms in order to determine whether the projectiles were expelled by them and/or cases detonated by them. In the course of criminal investigation, the production of expert evidence to identify the use of firearms is a determining condition for establishing the means used and indicating probable authorship. A form of ballistic confrontation is one carried out using a computerized system. This in silico ballistic confrontation contributes to the acquisition of optimized results, given the possibility of simultaneously confronting different ammunition elements. The Forensic Ballistics Laboratory of the Criminalistics Institute of the Civil Police of the Federal District uses the EVOFINDER® Computerized Ballistic Indexing System and, in the period from 2020 to 2023, produced 488 hits – exams with positive correlations – of which 273 reports were generated. Expert Intelligence that supported ongoing criminal investigations. Four cases were selected to illustrate the possibilities of the computerized ballistic confrontation tool.
