From Evidence to Insight: 3D Scanning Powers Crime Scene Investigation

Limitations of Traditional Crime Scene Documentation

For decades, investigators have relied on manual methods—tape measures, photographs, and hand-drawn sketches—to capture evidence. While standard practice, these methods present significant challenges:

• Time-consuming: Manual measurements and sketches can take hours
• Prone to errors: Missing details or incorrect dimensions can compromise cases
• Risk of contamination: Moving objects or stepping into the scene can destroy trace evidence
• Incomplete data: 2D documentation lacks depth, making reconstruction difficult and subjective

How 3D Scanning Transforms Crime Scene Investigation

3D scanning provides a non-invasive, high-accuracy approach to crime scene documentation. By creating a complete 3D replica of the scene, this technology offers significant advantages over traditional photographs and sketches:

• Preserve micro evidence: Document tiny but crucial details such as blood spatter patterns, bullet trajectories, shell casings, and fingerprints with sub-millimeter accuracy.
• Maintain spatial relationships: Capture the exact positions and distances between objects and evidence, eliminating the risk of errors during manual measurements.
• Virtual scene reconstruction: Investigators can revisit and analyze the scene anytime, even after it has been released, using immersive 3D models.
• Courtroom-ready visualization: High-resolution forensic 3D scanning for evidence preservation enables interactive, measurable evidence presentation.
