BASIC FOOTWEAR AND TIRE TREAD IMPRESSION PROCESSING

Instructor: Kasey Buckner Brager, CCSA, CFWE
Course length: 24 hours


As investigators, we are taught how to document and collect footwear and tire tread impressions at crime scenes but we are not taught how those techniques affect the comparison results. That is where this class is different than your typical basic footwear and tire tread documentation and collection class. This class will teach the proper skills needed and explain how improper techniques will hinder the comparison results.
​
This comprehensive 3-day, 24-hour course is designed to give investigators the knowledge and skills needed to properly document, collect and preserve 3D and 2D footwear and tire tread impressions to ensure the best results from the comparison examination. It is intended for new and experienced crime scene investigators and law enforcement officers. This course is a combination of lectures and hands on activities that will cover basic detection, collection and preservation techniques along with tips and tricks for difficult latent impressions that are often found on crime scenes. The hands-on activities will cover a variety of scene scenarios and enhancement processes that can be used on scenes and in the lab. This course will also discuss the importance of proper detection, collection and preservation techniques and how each will affect the comparison examination if not done correctly.

Course Topics:

  • History of Footwear Impressions
  • Types of Impressions
  • Scene Documentation
  • Photography of 3D and 2D Impressions
  • Secondary Recovery of 3D and 2D Impressions
  • Chemical Enhancement
  • Other Information from Tire Track Evidence
  • Other Information from Footwear Impressions
  • Importance of Proper Techniques
  • Information Needed for Examiner
 
What to Bring to the Course:

Casual attire is suitable and a laptop computer would be highly recommended. Please bring a digital camera with external flash, shutter remote, tripod and polarizing filter. If available, please bring an electrostatic dust lifter with milar film.
