Former medicolegal death investigators highlight the mental health challenges faced by medicolegal death investigation professionals, particularly the effects of indirect trauma. By sharing personal experiences, research data, and practical strategies, they aim to raise awareness about early signs of PTSD, stress, and burnout. Emphasizing the importance of resilience, community support, and vulnerability, the presentation encourages fostering trauma-informed workplaces and prioritizing wellness, including practical strategies.

Forensic science research is developing essential knowledge to fill in the holes in death investigations, creating new ways to identify challenging skeletal remains. These methods inform cause of death, time of death, and familial relationships to guide investigations, identify suspects, support prosecutions, and bring justice to families.

In 2014, NIJ established the Law Enforcement Advancing Data and Science (LEADS) Scholars Program to support research-minded, mid-career sworn law enforcement officers working to integrate research into agency policy and practice. The LEADS Scholars Program helps participants develop independent research and provides support to identify current evidence on priority issues.

The National Missing and Unidentified Persons System (NamUs) is a national centralized repository and resource center for missing, unidentified, and unclaimed person cases across the United States. NamUs helps investigators match long-term missing persons with unidentified remains to resolve cases and bring resolution to families.

The National Missing and Unidentified Persons System (NamUs) is a national centralized repository and resource center for missing, unidentified, and unclaimed person cases across the United States. NamUs recognizes the need for additional support for tribal communities and has dedicated resources to address missing and unidentified Indigenous persons cases.

This video is one of four from the Virtual Workshop Series: 3D Firearm Imaging, hosted by the NIJ Forensic Technology Center of Excellence from August 21 to September 11, 2024. This series is intended for firearm examiners or soon-to-be firearm examiners working in laboratories that have recently adopted 3D Firearm Imaging or are considering its adoption soon.

This video includes two presentations -

Plastic bags are present in many criminal cases. Analyzing these bags in a forensic case can sometimes identify the manufacturer. More importantly, forensic comparison of bags from a known box or other known source can determine whether the bag could have originated from that source. This webinar discusses the manufacturing process, class and randomly acquired characteristics, examination techniques, and comparisons between questioned and known bags. The final segment includes a discussion of recent research in this area, followed by a question-and-answer period.

Identification of novel psychoactive substances (NPS) based on comparisons of electron-ionization (EI) mass spectra continues to pose challenges in seized drug analysis. In this webinar, a method to statistically compare EI mass spectra is described, and an application of the method to distinguish several structural and positional isomers of NPS analogs are demonstrated.

This webinar was hosted by the NIJ Forensic Technology Center of Excellence on July 25, 2024. 

In this fireside chat, session six of the the Foundational Statistics for Forensic Toxicology series, panelists include practitioners and experts in forensic toxicology, and subject matter experts for the application of statistics in forensic toxicology. Join us in a dynamic and engaging session to explore common frustrations and challenges experienced in the laboratory, providing participants with valuable insights and practical solutions.

Session five of the Foundational Statistics for Forensic Toxicology series will incorporate concepts from earlier sessions and focus on the practical application of control data in estimating Measurement Uncertainty (MU). Rather than a discussion about how to calculate the MU, this session provides practical examples to demonstrate the key elements of the statistical process. Participants will learn how to incorporate control data into MU estimation by leveraging statistical techniques aimed at quantifying the uncertainty associated with measurement processes.

Of recent, forensic toxicology laboratories have been grappling with the emergence of tetrahydrocannabinol isomers within biological specimens. Traditional methodologies are often inadequate in the separation of Δ9-tetrahydrocannabinol and Δ8-tetrahydrocannabinol, which are the most common isomers identified in forensic testing.
