Highly toxic, synthetic drugs introduce significant health hazards to the forensic laboratory.  Understanding current knowledge and best practices will help laboratories manage their liability. This presenter covered topics such as known risks of handling hazardous drugs, creating a practical framework for the assessment, development, and improvement of safety systems, and additional research needed regarding exposure risks.

Molecular identification is advantageous for medicolegal death investigations involving entomological activity. This enables species-level identification of immature specimens necessary for estimating post-mortem interval and may be performed without specialized training or resources. The presenter describes a strategy effective for relevant species and demonstrates analysis of casework-type samples.

In this study, firearms examiners were asked to use traditional microscopic methods to identify unknown bullets to the appropriate barrels. Additionally, 3D scans of these bullets were used in a matching algorithm to find similarity scores between bullets. Error rates were determined and the potential for subclass carry-over among the barrels was evaluated.

This webinar will expand examiners' awareness of additional areas of interest for identification purposes. Two previously undocumented toolmarks were observed in Glock pistols and could potentially be used for other make/model pistols. These new toolmarks will expand an examiner’s ability to compare fired and unfired ammunition components to each other or to a suspect firearm.

This study assesses the production of subclass characteristics during the manufacturing of breech faces. Observations on how well subclass characteristics persist on manufactured breech faces with and without any finishing methods as well as the effect of the primer on the quality/quantity of the breech face impressions will be discussed.

The Overdose Detection Mapping Application Program (ODMAP) is a near real-time suspected overdose event surveillance platform developed by the Washington/Baltimore High Intensity Drug Trafficking Area (W/B HIDTA). The platform allows participating agencies to develop and implement response strategies that are tailored to their communities to help save lives.

The role of a death certificate has evolved from a legal record of death to a document used extensively by public and private entities to monitor the health of our nation. As the public health usage of death certificates continues to grow, it has become increasingly important to complete death certificates in a clear and consistent manner. This webinar will cover best practices for filling out death certificates in drug-related deaths.

With the increased prevalence of DART-MS in forensic laboratories comes an increased need for tools and resources. This webinar will highlight the new NIST/NIJ DART-MS Data Interpretation Tool (DIT), a freely available software tool that allows users to interpret DART-MS data resulting in improved presumptive screening of seized drug evidence. Other resources to assist with adoption and implementation of the DART-MS DIT will also be discussed.

Sam Quinones is a Los Angeles-based freelance journalist and an international award-winning author of four books of narrative nonfiction. Quinones’ latest book, The Least of Us: True Tales of America and Hope in the Time of Fentanyl and Meth, will be featured in this FTCoE webinar celebrating National Forensic Science Week.

This webinar will provide an opportunity to discuss some of the post-SWGTREAD considerations for articulating findings (interpretations, limitations, opinions, and results) as well as a platform to exchange thoughts, consider suggested conclusion structures, and observe examples related to articulating footwear evidence conclusions.
