Forensic and Investigative Sciences

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.

Awareness of how to provide culturally appropriate and trauma informed services to the American Indian/Alaska Native (AI/AN) community is important for forensic examiners. This webinar discussed includes jurisdictional factors affecting examinations, pertinent laws to consider, and health care services that may be available to AI/AN populations.

This webinar was presented by the NIJ Forensic Technology Center of Excellence on February 27, 2020.
 

Attendees will hear from experts in agricultural policy, hemp industry analytical testing, and the DEA Special Testing and Research laboratory to obtain a better understanding of the issues that have developed for forensic drug testing since the signing of the 2018 Farm Bill.  This webinar will provide a history of the Farm Bill as it relates to the legalities of hemp and tetrahydrocannabinol (THC).  Information on farming and quality testing used by the hemp industry will be presented.

Given the vital role of medical examiners and coroners (ME/C) in recognizing emerging trends in drug overdose deaths, partnering epidemiologists with ME/C offices can greatly enhance the utility of the significant volume of data generated by medicolegal death investigation. Epidemiologists from three unique ME jurisdictions—North Carolina, New Mexico and Virginia—share their experiences with monitoring drug overdose deaths, trends observed, and how best to utilize ME/C data to inform public health policy.

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.

This webinar built on the concepts presented in the webinar “The Time to Collect is Now: DNA Evidence in Groping Sexual Assault Cases” presented by Dr. Julie Valentine.

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.

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).

The results of a bloodstain pattern analysis are communicated through written reports and courtroom testimony.  Principles of communication science will be discussed and explained to develop the audience’s ability to transfer meaning through writing and verbal testimony.

The United Nations Office on Drugs and Crime (UNODC) Early Warning Advisory (EWA) on new psychoactive substances (NPS) was launched in June 2013 as a response to the emergence of NPS at the global level. The EWA aims to monitor, analyse, and report trends on NPS as a basis for effective evidence-based policy responses. It also serves as a repository for information/data on these substances and a platform for providing technical assistance, tools, and relevant analytical information for national drug testing and toxicology laboratories in member states.
