1 Strengthening Forensic Science in the Impression and Pattern Evidence Disciplines: The Changing Landscape Seventh Annual Prescription for Criminal Justice Forensics (June 3, 2016) Gerry LaPorte Director National Institute of Justice Office of Investigative and Forensic Sciences

2 Disclaimer Opinions or points of view expressed are those of the presenter and do not necessarily reflect the official position or policies of the U.S. Department of Justice

3 National Institute of Justice: Office of Investigative and Forensic Science Lead federal agency for forensic science research and development as well as the administration of programs to improve laboratory efficiency, reduce backlogs, and provide technical assistance

4 Mission of NIJ’s Office of Investigative and Forensic Sciences To improve the quality and practice of forensic science through innovative solutions that support research and development, testing and evaluation, technology, and information exchange for the criminal justice community

5 National Research Council (NRC) Report (2015) - Support for Forensic Science Research: Improving the Scientific Role of the National Institute of Justice NRC was asked to evaluate NIJ’s role in bolstering the forensic sciences research infrastructure. In September 2015, the NRC issued their report and found:  NIJ has a unique and critical role among the diverse federal agencies working to positively impact the progress of forensic science because, unlike other agencies, NIJ has a mission focus on forensic science research and development.  The efforts of NIJ have: (1) restored authority that is appropriate for a science agency and addressed some previous concerns about NIJ’s independence; and (2) contributed to the building of a research infrastructure necessary to develop and sustain research that advances forensic science methods.

6 Forensic Science Impact Highlights NIJ has supported the forensic science community with over $825 million from 2009-2014 More than 370,000 DNA cases have been funded resulting in over 157,000 CODIS uploads and 62,000 CODIS Hits

7 Forensic Science Impact Highlights More than 42,000 cold cases reviewed resulting in over 2,000 CODIS uploads More than 54,000 postconviction cases reviewed resulting in 27 exonerations More than 1000 research presentations, publications, and final technical reports

8 NIJ Philosophy on Research and Development Accurate and reliable forensic science based on research will make a difference in individual lives, public safety, and in creating a more effective and fair justice system Research must be guided by rigorous peer review Research must be innovative and provide answers to basic research questions as well as practical, applied solutions Forensic science research requires diversified expertise through partnerships and collaborations 8

9 9 Collaboration with Federal Agencies

10 NIJ Data: Forensic Science Research Culture is Changing The number of scientific publications resulting from NIJ supported research and development increased over 300% from projects awarded in 2007 compared to those awarded in 2012. The number of scientific presentations resulting from NIJ supported research and development increased over 400% from projects awarded in 2007 compared to those awarded in 2012.

11 Impression and Pattern Evidence Disciplines Friction Ridge Analysis (Latent Prints) Firearm & Tool Mark Examinations (FTE) Shoeprint and Tire Tread Evidence Questioned Documents/Handwriting Examinations Bloodstain Pattern Analysis (BPA) Misnomer: IPE Disciplines are ‘Comparison’ or ’Experienced-Based’ Disciplines

12 Other disciplines compare and rely on experience for interpretation
