BACKGROUND:
Accurately documenting a crime scene or fatal traffic accident takes a significant amount of time and is currently accomplished using traditional mapping methods with tape measures, measuring wheels, cameras, video cameras, and total stations to capture physical evidence. Using these techniques can take hours, or even days, to capture relevant parts of a scene.
A laser scanner can digitally capture the surrounding environment, as well as the shape of physical objects, using a line of laser light. This tool captures the environment, frozen at a moment in time, to include the conditions of the scene and the exact size and shape of items within. The result is a complete digital three-dimensional representation.
The scanning process captures up to two million points per second with scene details down to the millimeter. The laser scanner is more precise than a measuring tape or total station and helps reduce the amount of time to clear a scene while still recording a large amount of data.
Clearing a scene quickly allows staff to process crime scenes faster and with fewer people. Plus, most importantly, the laser scanner captures and preserves the scene as-is which allows officers to not only virtually revisit it but also the ability to create a virtual 3D model for investigators and court personnel.
Crime Scene Unit
The Crime Scene Unit logged almost 1,850 hours processing 16 major scenes since 2019. In 2022, the Crime Scene Unit processed over 600 crime scenes of which approximately 50 could have benefited from the use of a laser scanner.
