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.”

The National Missing and Unidentified Persons System (NamUs) provides technology, forensic services and investigative support to resolve missing persons cases.

Learn about the NIJ National Sexual Assault Policy Symposium held in September 2016 from its audience members and organizers. The Symposium focused on how the nation is moving forward and finding solutions to the complex issues that arise in sexual assault cases and in testing sexual assault evidence.

This seminar provides the first set of estimates from a national large-scale survey of violence against women and men who identified themselves as American Indian or Alaska Native using detailed behaviorally specific questions on psychological aggression, coercive control and entrapment, physical violence, stalking, and sexual violence. These results are expected to raise awareness and understanding of violence experienced by American Indian and Alaska Native people.

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.
