 The Investigative and Prosecutive Graphic Unit plans, designs, coordinates, and produces investigative aids and demonstrative evidence in support of FBI investigations. This support is provided in four general program areas:

  • Crime Scene Survey and Documentation—Provides two- and three-dimensional crime scene reconstructions and computer-animated modeling depicting bullet trajectory, line-of-sight, and vehicular and human movement analysis.

  • Forensic Facial Imaging—Provides composite drawings, two- and three-dimensional facial reconstructions from skeletal remains, facial age progressions, postmortem reconstructions, digital photographic manipulations/retouches, and wanted flyers.

  • Demonstrative Evidence—Provides charts, maps, diagrams, link-analyses, flow and check kite chartings, time lines, and technical renderings.

  • Administrative Support—Provides support to the Director's Office for congressional testimony and press briefings and to FBI Laboratory and Headquarters personnel.
