Forensic and Investigative Sciences

This webinar provided details and guidance for potential applicants to NIJ’s solicitation, “Research and Evaluation for the Testing and Interpretation of Physical Evidence in Publicly Funded Forensic Laboratories.”

NIJ Office of Investigative and Forensic Sciences Director Gerald LaPorte and Deputy Director Heather Waltke, along with Heather LaSalle, Forensic Examiner, DNA Casework Unit, and Tina Delgado, Chief, Biometrics Division from the FBI Laboratory discuss how scientific advances can help jurisdictions process a large number of previously unsubmitted sexual assault kits.

Brian Cerchiai discusses a NIJ-supported a study conducted by the Miami-Dade Police Department on the accuracy of fingerprint examiners. The study found that fingerprint examiners make extremely few errors. Even when examiners did not get an independent second opinion about their decisions, they were remarkably accurate. But when decisions were verified by an independent reviewers, examiners had a 0% false positive, or incorrect identification, rate and a 3% false negative, or missed identification, rate.

The NIJ-sponsored Expert Working Group on Human Factors in Latent Print Analysis is clarifying potential sources of error in pattern recognition analysis. It will develop best practices to remove or minimize these sources. NIJ is addressing recommendations in the 2009 National Academy of Sciences' report titled "Strengthening Forensic Science in the United States: A Path Forward." Specifically, the panelists focus on recommendation 5, which encourages research programs on human observer bias and sources of human error in forensic examinations.
