Forensic sciences

This workshop explores the impact inconsistent drug analysis reporting has on public health and public trust. The value and implementation of the Global Uniform Analysis and Reporting of Drug-Related Substances (GUARDS) innovative methodology in over 200 instruments across United States Drug Enforcement Administration (DEA) laboratories are presented, as well as the efforts of other labs of the U.S. Customs and Border Protection (CBP) and Illinois State Police.

Misconceptions abound regarding the role of medicolegal death investigation (MDI) professionals, particularly the pervasive belief that they solely work with and for the deceased. This perception often leads to a public reluctance in engaging with medical examiner and coroner (MEC) systems, especially from stakeholders who hold the proverbial purse strings. The reality is, MDI data impacts the living, from assisting grieving families to influencing public health at regional and even national levels.

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.

Following a multi-month course of data collection using simulated human gravesites, Ground-Penetrating Radar (GPR) researcher Jordan Mullikin will discuss the advantages and disadvantages of GPR for the detection of unmarked graves. Additionally, this webinar will explore Light Detection and Ranging (LiDAR) technology for the same purpose and investigate the potential integration of both technologies for optimal detection of clandestine graves within the law enforcement and forensic communities.

Numerous crime laboratories have witnessed a surge in gun-related evidence submissions, leading to an increased demand for DNA testing and entry into the National Integrated Ballistic Information Network (NIBIN) for firearms-related investigations. Simultaneously, the forensic value of firearms analysis has substantially grown, owing to advancements in DNA technology and the expansion of the NIBIN database. Consequently, several forensic labs have established dedicated units specifically focused on comprehensive firearms analysis.

This presentation describes the nature of the merge of the e-cigarette and cannabis industries. Quality assurance issues as a result of the absence of regulation and oversight is described. Cases of self-reported adverse events and the challenges of cannabis product analysis are also discussed.

With the passage of the 2018 Agricultural Improvement Act (Farm Bill), forensic laboratories have been tasked with differentiating seized cannabis samples as either hemp or marijuana. The new legislation declassified hemp as a Schedule 1 drug substance and defined it as cannabis containing 0.3 % or less of decarboxylated-Δ9-THC (total Δ9-THC). The National Institute of Standards and Technology (NIST) has been working to help forensic laboratories with these challenging measurements through the development of extraction protocols and analytical methods.

The reauthorization of hemp due to the Agriculture Improvement Act of 2018 (Farm Bill) has caused a proliferation of products that contain cannabidiol (CBD). While CBD is considered ‘legal’ under the Farm-Bill, there are concerns that the labeling of CBD products is inaccurate, and that the products may contain other cannabinoids, including Δ9-tetrahydrocannabinol (THC), the main psychoactive compound in marijuana. Other concerns include the potential for conversion of CBD to other cannabinoids during analysis of biological matrices and in acidic foods and beverages.

Dr. Julie L. Valentine provides background information on the challenges in tracking prosecution outcomes in sexual assault cases of adult victims. Research utilizing the National Institute of Justice Sexual Assault Nurse Examiner Practitioner Toolkit in two Utah counties is presented. Variables predicting prosecution are be explored. Participants are invited to consider societal, structural, and legislative barriers to prosecution of adult sexual assault cases faced in their jurisdiction to encourage multidisciplinary collaboration.

Dr. Julie L. Valentine introduces the application of touch DNA in sexual assault cases through a case study. A literature review on touch DNA is summarized to provide contextual information and research on touch DNA analysis findings in groping sexual assault cases is discussed. The webinar concludes with recommendations for multidisciplinary partners to collect, submit, and analyze evidence in sexual assault cases for touch DNA.

Dr. Julie Valentine shares background information on dating app usage and user demographics to provide context for research findings on dating apps and sexual assault. Research findings are presented on sexual assaults committed at the first in-person meeting when the victim and assailant met on a dating app compared to other sexual assaults not associated with dating apps. Practice and policy recommendations are shared to improve dating app safety.

One of the biggest challenges that Forensic Laboratories face is hiring and retaining great employees. The loss of one person has a domino effect on the operations of the laboratory and has a direct impact on the departments they serve. This presentation outlines some of the ways that the Mesa Forensic Services Laboratory and the Texas Department of Public Safety Crime Laboratory Division have been able to hire and retain great employees.

Change can be intimidating and making a transition to a paperless system can be daunting task. This presentation discusses two perspectives on how laboratories embraced technology for administrative and casework processes, the lessons learned, and the vision for additional growth.

This webinar presents laboratory managers with a discussion on case management in forensic science laboratories. All forensic science laboratories struggle with caseloads and backlogs in some way and to varying extremes. The answer to this struggle is a process to manage caseloads through evidence triage, case information management, and communication. A discussion on the challenges involved in case management is followed by practical experiences in writing and implementing case management policies.
