Event
2018 Impression, Pattern and Trace Evidence Symposium
Date & Time
January 22nd – 25th, 2018
Location
Renaissance Hotel, Arlington, VA
Overview
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.
Funding for the 2018 Impression Pattern and Trace Evidence Symposium is provided through a cooperative agreement with the National Institute of Justice [2016-MU-BX-K110], Office of Justice Programs, US Department of Justice.
Workshop In-Brief Reports
The FTCOE hosted 13 interactive workshops spanning several topics, including firearm and tool mark examinations, probabilities and likelihood ratios in pattern evidence, and applied polarized light microscopy. Short in-brief reports were compiled on three of the workshops to summarize the purpose of the class, the lecture material, and the exercises completed. Click each title below to view the in-briefs.
