Stability and Persistence of Touch DNA for Forensic Analysis

Marzo 2021

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.

This webinar was presented by the NIJ Forensic Technology Center of Excellence on March 11, 2021.

Structural Characterization of Emerging Synthetic Drugs by Mass Spectrometry

Marzo 2021

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 was presented by the NIJ Forensic Technology Center of Excellence on March 5, 2021.

Virtual Conference on School Safety - Welcome Message, Overview of CSSI, and a Philadelphia Story

Febrero 2021

On February 16-18, 2021, the National Institute of Justice hosted the Virtual Conference on School Safety: Bridging Research to Practice to Safeguard Our Schools. This video includes a welcome message, an overview of the Comprehensive School Safety Initiative and School Safety Research at NIJ, and the presentation on "A Philadelphia Story: Innovating and Improving in a Large Urban District," by Abigail Gray and Kevin Bethel, School District of Philadelphia.

Novel Synthetic Opioids in Oral Fluid Analytical Methods and Prevalence

Febrero 2021

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.

Preemptive Approach to Combatting and Characterizing Emerging Synthetic Opioids

Febrero 2021

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.

Emerging Methods for Body Fluid Analysis

Enero 2021

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.

Expanding Research to Examine the Impacts of Forensic Science on the Criminal Justice System

Diciembre 2020

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.

Dual System Youth: At the Intersection of Child Maltreatment and Delinquency

Diciembre 2020

Across the country, child welfare and juvenile justice systems now recognize that youth involved in both systems (i.e., dual system youth) are a vulnerable population who often go unrecognized because of challenges in information-sharing and cross system collaboration. In light of these challenges, national incidence rates of dual system youth are not known.
