The recent arrest of influencer Javier Arias in Necoclí, with the discovery of an arsenal and cash, presents a complex criminal scene. In these cases, traditional forensic documentation is crucial, but it has limitations. Scene analysis using 3D technologies emerges as a powerful tool to preserve, analyze, and present evidence in an immutable and accessible way for the entire judicial process.
Forensic documentation with photogrammetry and laser scanning 🔍
The first intervention would be to capture the scene with photogrammetry and 3D laser scanning. This generates an exact digital model, a forensic twin, where each piece of evidence is georeferenced: the position of each pistol, the pile of cartridges, the stacks of money. This measurable point cloud allows for visibility analysis, trajectories, or accesses, and permanently preserves the original spatial context, something that flat photographs cannot achieve.
Virtual reconstruction for justice ⚖️
With the base 3D model, an interactive reconstruction can be developed in a game engine. A prosecutor or expert could virtually walk through the scene, examine objects from any angle, and present a clear narrative to the judge or jury. This digital replica facilitates remote expert examinations, avoids contamination of the real scene, and becomes a robust and understandable documentary proof, strengthening the digital chain of custody.
How can the 3D analysis of the scene from the operation against Javier Arias reconstruct and quantify the spatial distribution of the arsenal and money to validate the case hypothesis?
(PD: In scene analysis, each scale witness is an anonymous little hero.)
