Original Release Date: March 12, 2018

In episode six of our 2018 IPTES Season, Just Science interviews Chris Hamburg, from the Oregon State Police Forensic Services Division, and Jeff Jagmin from the WSP Crime Laboratory Division in Seattle. Our guests discuss the process a footwear examiner goes through in order to capture test impressions. Their interactive workshop “Intra- and Inter-variability of Footwear Test Impressions” had attendees go through this footwear examiner process. The attendees could then see for themselves what variations occur on the test impressions depending on the examiner’s physical variations, such as height and weight.

NIJ and FTCOE are committed to improving the practice of forensic science and strengthening its impact through support of research and development, rigorous technology evaluation and adoption, effective knowledge transfer and education, and comprehensive dissemination of best practices and guidelines to agencies dedicated to combating crime. The future of forensic sciences and its contribution to the public and criminal justice community is a motivating topic to gather expertise in a forum to discuss, learn, and share ideas. The IPTES was specifically designed to bring together practitioners and researchers to enhance information-sharing and promote collaboration among the impression, pattern, and trace evidence analysts, law enforcement, and legal communities.
