Marijuana Analysis in a New Frontier: Two State Laboratory Approaches

March 2020

After the Agriculture Improvement Act of 2018 (Farm Bill) was enacted in December 2018, many states rushed to make changes to their own laws to allow the hemp industry to grow and thrive in their jurisdictions. By removing hemp from the Controlled Substances Act, Cannabis sativa L. plant material with a concentration of delta-9-tetrahydrocannabinol less than 0.3% on a dry weight basis was no longer considered marijuana.

Toxicology: Instrumentation, Methodology and Workflows, ASCLD Train the Director Series

February 2020

Legacy workflows in toxicology generally involve a drug class screen followed by a gas chromatography/mass spectroscopy (GC/MS) and liquid chromatography mass spectroscopy (LC/MS-MS) confirmation analysis. Additional techniques could also be used in workflows, but their applications were focused on specific drugs. In general, analyses were serial, limited, and often required multiple methods depending on the number of drug classes in the samples. Results required lengthy and costly workflows, especially when toxicologists were working with complicated samples.

Investigative Genetic Genealogy: Background and Crime Lab Strategy

January 2020

In this webinar we discussed the theory and development of Investigative Genetic Genealogy, including some ethical and legal considerations raised by this technique.  Additionally, we explored the current status of case investigations, the impact on crime laboratories, implementation strategies, and recommendations for jurisdictions considering applying Investigative Genetic Genealogy to their unsolved cases.

This webinar was presented by the NIJ Forensic Technology Center of Excellence on January 23, 2020. 

Quality Assurance: Beyond Accreditation, ASCLD Train the Director Series

January 2020

In this webinar, we will discuss quality and accreditation, how they fit together, and the ASCLD Accreditation Roadmap and Toolkit.  We will also discuss the concepts of organizational transformation, organizational culture, and the cultivation of a quality culture in your laboratory. Lastly, we will review the various quality initiatives in forensics, including ISO TC 272, the Organization of Scientific Area Committees (OSAC) for Forensic Science, and the scientific and technical working groups (SWG/TWG).

Stress, Vicarious Trauma, and Resiliency for Forensic Science Professionals

June 2020

This webinar presented the findings of the ASCLD/NIJ collaborative Gap Assessment of Stress, Vicarious Trauma and Resiliency for Forensic Science Professionals. The assessment gathered survey responses from forensic and medical examiner laboratories to evaluate vicarious trauma, burnout, job satisfaction, and participants perceptions of their organization’s resiliency efforts.  Our findings inform future directions in research, policy, and practice to better manage stress and increase resiliency among forensic professionals.

Tackling Employee Wellness: The Phoenix Police Department’s Crime Lab Approach

Drug Exposures in the Forensic Laboratory: What We Know, What We Can Learn

June 2020

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 of Insects Relevant to Medicolegal Casework

December 2021

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.

Two-Pronged Study of Bullets Fired by Consecutively Rifled Barrels

December 2021

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.

Glock Pistol Toolmarks: A Literature Review and Introduction of Undocumented Toolmarks

December 2021

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.

Exploration of Breech Face Subclass Characteristics

December 2021

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.

Harnessing Data to Implement Real time, Data Driven Overdose Response Strategies

December 2021

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.

Death Certification by the Medical Examiner/Coroner in Drug Related Deaths

November 2021

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.
