3D Laser Scanning in Crime Scene Investigations

In a shocking incident, Charlie Kirk, founder of the organization “Turning Point USA,” was killed after being shot while speaking at Utah Valley University. Authorities arrested a suspect named Tyler Robinson after an extensive manhunt. This incident highlighted the use of modern technology in criminal investigations, specifically 3D laser scanning technology.

The Importance of Preserving the Crime Scene

Preserving the crime scene is a crucial step to ensure that investigations proceed correctly. Elements of a crime scene can change quickly, with furniture or vehicles being moved or misplaced. This underscores the importance of using modern techniques such as 3D laser scanning, which allows for precise documentation of everything.

This technology is routinely used in major crime scenes, scanning everything in the area using light to create a 3D map of every object present. This accurate record enables investigators to revisit the crime scene repeatedly to examine measurements, angles, and distances, contributing to strong evidence in trials.

The History of Laser Scanning Technology

One of the early experts to use this technology in crime investigations was Michael Haag, who worked as a shooting incident reconstructionist for the Albuquerque Police Department in New Mexico. Haag began using 3D laser scanning in the early 2000s, with his expertise in chemistry and physics helping to develop this technology for use in criminal investigations.

Haag and his private company use this technology to provide training services in shooting incident reconstruction globally. He also testifies in courts about how 3D laser scanning is used to document and analyze crime scenes.

How 3D Laser Scanning Works

3D laser scanning is a highly advanced and effective engineering tool. The basic method involves placing the scanner on a stable tripod that rotates 360 degrees horizontally and moves vertically. The device emits millions of light “bullets” to measure distances with high accuracy down to a few millimeters.

The device is then moved from one location to another to build a spherical 3D data set that is merged to create a complete image of the crime scene. This data is used to display the scene in 3D, allowing judges, juries, and investigators to view the scene exactly as it was at the time of the crime.

Applications of Laser Scanning in Investigations

In the case of the shooting of Charlie Kirk, laser scanning is used to determine potential shooting locations by analyzing angles and distances and identifying possible bullet trajectories. While some scenes may not be as complex as others, laser scanning provides an accurate understanding of the actual location of different elements in the crime scene.

In addition to preserving the scene for future purposes, this data can be used to create virtual presentations that show potential perpetrator locations and display the angles from which shots could have been fired.

Conclusion

3D laser scanning technology demonstrates the importance of modern technology in crime investigations. By documenting crime scenes with exceptional precision, investigators can present strong and reliable evidence in trials. These technologies also contribute to a better understanding of complex events, increasing the likelihood of achieving justice for victims. Ultimately, using these technologies is a step toward a safer and more effective future in criminal investigations.
