Abstract

From January 22 to 25, 2018, RTI International, the National Institute of Justice (NIJ) and the Forensic Technology Center of Excellence (FTCoE) held the 2018 Impression, Pattern and Trace Evidence Symposium (IPTES) in Arlington, VA, to promote collaboration, enhance knowledge transfer, and share best practices and policies for the impression, pattern, and trace evidence forensic science communities. 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. It’s about becoming part of an essential and historic movement as the forensic sciences continue to advance. 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. The IPTES was designed to bring together practitioners and researchers to enhance information sharing and promote collaboration among impression, pattern, and trace evidence analysts, law enforcement, and legal communities. This set of proceedings comprises abstracts from workshops, general sessions, breakout sessions, and poster presentations.

Highlights

  • On behalf of Reflection transformation imaging (RTI) International, the National Institute of Justice (NIJ) and the Forensic Technology Center of Excellence (FTCoE), we would like to present the proceedings from the 2018 Impression, Pattern and Trace Evidence Symposium (IPTES)

  • Our own past experience with teaching workshops has demonstrated that practitioners can appreciate and understand probability and likelihood ratios (LRs) without needing any particular prerequisite other than logical thinking

  • The hands-on approach was crucial to ensure that the participants understand both the sample preparation techniques and morphological characteristics needed for success in wood characterization

Summary

Introduction

The focus of this work is on developing a fracture mechanics-based analysis with quantified match probabilities for forensic physical matches for a variety of materials Both the National Research Council (NRC) in 2009 and the President’s Council of Advisors on Science and Technology (PCAST) in 2015 urged the forensic science community to put “more science into the forensic science.”. The presentation will discuss the commonalities across disciplines and how the disciplines can be considered as being subsets of the examination of shapes This approach is of particular value today when many law enforcement forensic laboratories, due to staffing shortages, are dropping fire debris analysis as a provided service or are assigning such cases such low priority that they are not analyzed in a reasonable time. Information handled in this way becomes “smart data” and supports extended queries and inference
