Crime Scene Documentation

General Information

We provide technical support for the following:

  • Crime scene survey
  • Crime scene documentation
  • Demonstrative court presentation
  • Three-dimensional physical models
  • Crime scene photography

We support FBI operations by providing accurate and timely technical, photographic, and structural services for counterterrorism, counterintelligence, criminal investigative, and forensic investigations and prosecutions.

Highly-trained visual information specialists and scientific and technical photographers from the FBI Laboratory’s Operational Projects Unit use high-end computer aided design (CAD), three-dimensional (3D) modeling, and computer animation functionality in their daily applications which enhance the unit’s field investigative support. Unit personnel can travel both domestically and internationally to provide crime scene support.

Survey, Documentation, and Photography

Unit personnel can provide detailed and accurate on site documentation for:

  • Crime scenes
  • Bullet trajectory
  • Accident reconstruction
  • Bombings
  • Plane crashes, and more

Types of Survey and Documentation

  • Traditional measuring methods
  • Total station survey
  • Tripod or roof mounted laser scanner with digital camera and GPS options

3D Laser scanning technology can also be utilized for on-going, “real time” operations such as hostage situations requiring immediate on-site measurements or for major planning.

Three-Dimensional Physical Models

The data collected from these methods, by OPU or any agency, will enable OPU to prepare concise (to scale) 2D or 3D demonstrative evidence. In addition, the scan system will also be used for the high resolution scanning and documentation of objects such as bomb components, bomb fragments, firearms, vehicle interiors, etc.

Operational Projects Unit personnel create two- and three-dimensional crime scene diagrams, three-dimensional digital and physical models, computer animation, digitally interactive scene, scenario reconstructions, and scientific and technical photography.
