The Advanced Crime Scene Reconstruction: Using Graphic and Virtual Models as Analytical Tools course provides instruction in visualizing the context in which events took place in order to create a comprehensive and accurate scene reconstruction.  Graphics and virtual models, often used as demonstrative court exhibits, are valuable tools for analyzing available data, evaluating scenarios, and determining the truth about what did or did not happen during the event.  

Course Description:
This 5-day (40 hour) Advanced Crime Scene Reconstruction: Using Graphics and Virtual Models as Analytical Tools course is designed by veteran field experts for detectives, crime scene investigators, crime scene technicians, and others involved in crime scene analysis.  Through lecture and practical exercises, investigators expand their reconstruction skill sets by using organizational tools, open source design, animation and image editing software, and reconstruction methodology to test and analyze scenarios in the context of the scene.

Classroom instruction and practical exercises include:
  • Methods for electronically organizing evidence and analysis for reconstruction
  • Techniques for detailed analysis of images
  • Building realistic 2D and 3D crime scene models from scene measurements or scanner data   
  • Correlating images to the crime scene through interactive documents
  • Interpreting and transposing autopsy data to virtual models to test scenarios in a virtual scene based on the data collected
  • Incorporating interoperable data sources into a scene model
  • Implementing reconstruction methodology to reconstruct the events of a crime scene
  • Exploring the power of PowerPoint to prepare reconstruction presentations or reports
  • Developing a case presentation using graphics and virtual models (Students will apply concepts in the analysis of historically based case scenarios)

Class Requirements:
Prior investigative or crime scene experience and previous training in crime scene reconstruction is preferred.   Familiarity with basic bloodstain patterns is helpful.   Course materials are provided in electronic format.  Attendees should bring a laptop computer with USB connection with capability of installing course information and software, including office suite, image editing, and computer-assisted drawing programs.  Attendees should bring a current or closed case; students will practice techniques on both instructor-provided case and their own case.

This course has been approved for 40 hours of certification/re-certification training credit by the IAI Crime Scene Certification Board.
