This first webinar is an introduction to NMDID. Attendees will learn about the history of the database and the team that developed it. There will be a tour of the website, including data use agreement, “how to use” videos, descriptions of basic data types, and an introduction to the data dictionary.

This webinar was presented by the NIJ Forensic Technology Center of Excellence on October 7, 2020.

Many working with genomic DNA can afford to lose large portions of it during its extraction without negatively impacting downstream analysis. However, with work targeting highly degraded DNA sources, retention of every molecule can be key to successful analyses. This webinar addressed the insufficient documentation of absolute efficiencies of extraction methods and the nature of DNA loss associated with the study of low copy number and degraded DNA samples.

This webinar will provide an evaluation of the DEPArray™, a system that enables the identification, separation, and recovery of single cells or groups of cells from heterogeneous mixtures. The workflow described in this webinar will highlight the impact this instrument, with standard forensic processes, will have on processing sexual assault evidence and improving the success of single cell analyses. We will present results of the NIJ funded study—An automated dielectrophoretic-based single cell separation technique to improve laboratory efficiency, mixture deconvolution and combat sample inhibition, (2015-NE-BX-K002)—and provide new data on the viability of single cell analysis.

This webinar focused on the use of PACE™, a method developed by Syracuse University, to perform artifact management and probabilistically predict the number of contributors (NOC) in forensic DNA samples. This is performed using a combination of biological modeling and machine learning, permitting high accuracy NOC calls (greater than 90%) of complex mixtures. It does so rapidly (seconds to minutes) without the need for high performance computing resources. We discussed the design and development of the PACE system, how to interpret the output, and provided recommendations on how to implement the system in a forensic laboratory. This included a full demonstration of the software and how to navigate the interface and read reports. Finally, we discussed a current project funded by the NIJ that seeks to develop PACE for sequencing-based analyses.

Residential structure fires are predominantly fueled by synthetic contents and commonly become ventilation-limited. Therefore accounting for the impact of ventilation on fire is important. Examining flow paths within the structure can aide in fire pattern analysis.

Using a typical OEM paint system, the PDQ Maintenance Team will walk through the best practices to efficiently use the database and spectral libraries to identify the most likely source of an unknown paint system. Details gathered from this process include manufacturing plant, year range, and models.

The Royal Canadian Mounted Police Paint Data Query (PDQ) program is an international OEM automotive paint database used to help identify possible suspect vehicles involved in hit and run incidents based on paint evidence left at the scene of a crime. Paint systems on an automobile typically have three or four layers: a clear coat over a topcoat over one or more undercoats. Each paint layer contains pigments, fillers, and binders. Automotive manufacturing plants often use unique combinations of paint layers, which allow forensic scientists to determine the most likely manufacturing plant, make/model, and year range for the vehicle from which the paint chip originated.
