2018 IPTES – Trace Evidence Breakout Day 2 PM

2018 IPTES – Trace Evidence Breakout Day 2 PM


IPTES was 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. This original Live Webinar took place on 01/25/2018.

The National Institute of Justice (NIJ) and the Forensic Technology Center of Excellence (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.
