This webinar provides an overview of the National Institute of Standards and Technology (NIST) National Software Reference Library (NSRL) Reference Data Set (RDS). The NSRL hash set changes to a new format beginning March 2023, bringing several new capabilities into the hands of digital evidence practitioners. Examples shown enable the creation of case-specific hash sets and searches for notable files. A new update process is also demonstrated.

This webinar describes a simple and systematic method for comparing fracture fits using standardized qualitative and quantitative criteria. An extensive database of nearly 9,000 samples of duct tapes, automotive polymers, and textiles is used to estimate performance rates and strengthen the scientific foundations of fracture fit determinations. Also, the consistency of results from inter-laboratory studies shows the utility and reliability of the proposed approach.

This presentation introduces scoring procedures for dental morphological traits of the molars that can be employed in population affinity estimates for forensic anthropological casework. While common traits, such as shoveling and Carabelli’s trait, are briefly discussed, the focus on molar morphology promotes a greater understanding of informative, less commonly utilized traits that often preserve better in forensic case settings.

The Phoenix Police Department (PPD) made a department-wide cultural change in evidence handling, screening, and processing strategies in support of Crime Gun Intelligence Center goals. In addition, the Firearms Section of the PPD Crime Laboratory has validated and implemented a 3D topographical Virtual Comparison Microscopy (VCM) system. The presenters will discuss how the addition of 3D VCM technology in the laboratory and the incorporation of 3D technologies into the NIBIN system has bolstered their ability to provide the best results possible to our customers.

This webinar provides a high-level overview of the Dominance, Influence, Steadiness, and Conscientiousness (DiSC) Personality Assessment tool and its application in workplace settings. Attendees learn how DiSC helps identify individual behavioral styles—Dominance, Influence, Steadiness, and Conscientiousness—and fosters better communication, teamwork, and productivity. The presentation explores practical insights into understanding colleagues' unique preferences and adapting your communication strategies for a more effective workplace.

Effective leadership communication plays a vital role in promoting meaningful change within an organization. This presentation explores key principles such as “modeling the way”, “inspiring a shared vision”, and “start with why”. Vision-driven communication requires crime laboratory supervisors to utilize various communication tools while they act as a driving force within the organization, leading their teams to success.
