The focus of this project was the application and limitations of technology used for fire investigations. Today’s field-portable GC/MS) systems were found to provide lab-quality data for volatile hydrocarbons but the interpretation of that data proved challenging for field operators. Online access to lab experts is essential.  Evidence sampling is enhanced with the use of sensitive Photoionization Detectors (PID) as a supplement to canine searches.

COVID-19 has had an enormous effect on the workforce, and not just in the areas of operations and logistics.  Workplace schedules have been completely rearranged, work-life balance has been turned on its head from telework, and reduced “in lab” hours have caused strain on an already stressed workforce.  In this webinar, you will hear from three experts in workplace wellness, particularly in forensic science.

This webinar will explore some of the key elements that must be considered to successfully implement a Remote Work program in an operational forensic laboratory. Three leaders from County, State and Private labs will share their respective experiences on how to pivot to this new normal in the middle of a pandemic.

Touch DNA is a potentially powerful sample type for forensic casework, but is challenging to work with due to low quantity, variable deposition amounts, and fundamental questions regarding stability over time. In this webinar we describe best-practices and initial results related to comprehensive studies of the stability of touch DNA after exposure to different environmental conditions.

The primary focus of this presentation is to develop a better understanding of the fragmentation behavior of emerging synthetic drugs in different types of mass spectrometers. The goal is to assist practitioners in seized drugs and forensic toxicology with their understanding of current casework, and to help them more-readily identify new drugs as they emerge.

This webinar will discuss the analytical methodology developed and validated to identify and quantify novel synthetic opioids and traditional opioids in oral fluid. The presenter will also discuss targeted and non-targeted approaches using liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods for detection of fentanyl- and non-fentanyl related novel synthetic opioids. Additionally, this webinar with cover sample preparation techniques for isolating synthetic opioids with various chemistries and structures.

This webinar seeks to describe how preemptive synthesis and characterization of potent psychoactive substances from the literature can aid forensic scientists in the identification of unknowns appearing in samples emerging from illicit markets. Additionally, the presenter seeks to provide understanding of how gaps in pharmacological knowledge of old drugs can be exploited to find new emerging synthetic drugs.

The NIJ Forensic Technology Center of Excellence hosted a panel of subject matter experts to discuss emerging methods for body fluid analysis. This webinar is in three sections: 1) Proteomics and its potential in high-throughput forensic laboratories. 2) Surface Enhanced Raman Spectroscopy and the rapid detection and identification of body fluids. 3) MicroRNA, mRNA, and the development of a microfluidic device used to detect and differentiate body fluids from an unknown sample.

In 2004, the National Institute of Justice created the social science research on forensic sciences (SSRFS) research program to explore the impact of forensic sciences on the criminal justice system and the administration of justice. Much of the early research from the SSRFS program focused on DNA processing and the use of DNA in investigations and prosecutions.

This webinar, presented in four parts, provides a definition for the phrase “death in custody” and will describe all phases of custody. Additionally, the presenter will highlight case studies of deaths, including the five manners of deaths and a special focus on drug-related deaths. Lastly, he will provide a brief overview of the position paper issued in 2017 by the National Association of Medical Examiners (Academic Forensic Pathology, 2017). This paper outlined the best practices for examination, death determination, and manner of death classification.

In recent years, NIJ invested in several research projects to advance understanding and inform prevention of public mass shootings.

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.

This webinar will demonstrate the use of the open source 3D Slicer software platform (https://www.slicer.org/) for visualizing 3D medical imaging datasets and collecting quantitative data from those images, including linear/angular, landmark-based, and volumetric data.

This webinar was presented by the NIJ Forensic Technology Center of Excellence on October 28, 2020.

In the third webinar, participants will learn about the image data included in the New Mexico Decedent Image Database, including how to open and view an image series, the different viewing functions, and how to access detailed information about the images.

Based on the review of various forms of STR typing results and factors that impact the presence or condition of DNA on evidence, instructors in this installment of Probabilistic Genotyping of Evidentiary DNA Typing Results lay a foundation for the interpretation of forensic DNA typing results. The session will begin with background information on forensic DNA analysis, including terminology and mechanisms, to help all participants comprehend the material covered in this series.

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.

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 introduced the importance of network forensics, which included capturing network traffic and reconstructing digital artifacts. Presenters discussed big data challenges, open-source tools, and the new toolkit FileTSAR.

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.

This webinar discussed intact low explosives analysis with a focus on microscopical methods. It covered terminology for explosives, the rationale of low explosives analysis for most crime laboratories, six categories of low explosives, and examples of three analyses using microscopical methods.

This webinar highlighted the results of a full developmental validation of a method that estimates the A Posteriori Probability (APP) of the number of contributors in a DNA sample(NOC), and demonstrated that estimating the APP based on peak heights outperforms methods that rely on binary determinations alone. This presentation focused on including the true NOC in Likelihood Ratio interpretations and on repeatability.
