A shooting scene, or any crime scene, stays fresh for only a very short time. For that reason, careful mapping and data collection is critical. The equipment and software options discussed in this article are worth considering while keeping in mind personal preference and budgetary constraints. A reliable and accurate depiction of the crime scene, the diagram that one creates, goes hand-in-hand with mapping and data collection. The diagram, in a comprehensive 3D format, is what keeps the scene and its details fresh in the mind of all who may be called upon to evaluate the events. Crime scenes that results from shooting incidents can be very complex to map and investigate. When the case comes to trial, the event must be carefully and accurately explained to the jury. Meticulous documentation of the crime scene and the evidence presented in a comprehensive 3D format will help the jury understand precisely what happened at the crime scene. A closer look at some of the methods for gathering shooting scene evidence and how best to present the evidence in the courtroom, can help explain why careful, accurate investigations of these particular scenes are so critical.
