This webinar will provide an overview of overdose fatality reviews (OFRs) with a specific focus on engaging partnerships with coroners, medical examiners, and medicolegal death investigators. The presenters will highlight OFRs that have been implemented by engaging the medicolegal death investigation system and will discuss challenges and recommendations associated with implementing an OFR. The webinar will consist of three presentations on OFRs highlighting a county-level, a rural community, and a state-wide approach.

This webinar was presented by the NIJ Forensic Technology Center of Excellence on July 27, 2021.

Over the last ten years, numerous novel psychoactive substances (NPS) have emerged in the recreational drug supply. Upon synthesis or discovery, each of these drugs has been given a name other than its IUPAC chemical name, primarily for ease of communication. This has resulted in various naming convention for NPS, sometimes multiple within a given subclass. This webinar is aimed at tackling the naming conventions for NPS and the associated challenges encountered along the way.

Microhaplotypes (microhaps) are biomarkers fewer than 300 nucleotides long that display multiple allelic combinations. The main advantages of microhaps over conventional short tandem repeats (STRs) include the 1) absence of stutter, 2) same-size alleles within each locus, 3) lower mutation rate, and 4) ancestry informative alleles. These forensically relevant loci can yield a power of discrimination similar to STRs while enhancing human identification (HID), mixture deconvolution, and biogeographic ancestry prediction. In this presentation, the subject matter expert will discuss the current status of the research conducted in the GW-FMB lab on a new multi-function DNA marker and its potential impact to the field of forensic genetics.

LatentSleuth is a novel software tool set designed for (and with direct feedback from) latent print examiners. The toolset includes a small-scale automated fingerprint identification system (AFIS) matcher that leverages a novel matching algorithm that calculates a warp between a latent print image and a given reference print image. This webinar will demonstrate a comprehensive quantification of a latent images entire structure and how that quantification is exploited in a commercially available workstation for latent print examination.

In the sixth and final webinar, participants will be introduced to the use of PMCT in the investigation of a variety of unnatural deaths not discussed in previous webinars.  Topics include overdose deaths, select asphyxial mechanisms of death, and sharp force injury.

In the fifth webinar, participants will be introduced to the use of PMCT in the investigation of natural deaths.  At the New Mexico OMI, a PMCT scan may be used to rule out trauma in apparently natural deaths, or to confirm a natural cause of death.  Depending on investigative details (circumstances, age, and medical history), and the PMCT findings, pathologists may choose to perform an external exam or a full autopsy.

In the third webinar, participants will be introduced to the use of PMCT for examining decedents with gunshot wounds, both homicidal and self-inflicted. At the New Mexico OMI, a PMCT scan is performed in virtually all gunshot wound (GSW) related deaths. In cases of suspected homicide or suspicious suicides, autopsy is also performed. However, in non-suspicious cases involving self-inflicted GSW, PMCT is combined with an external examination, and sometimes a partial autopsy to retrieve a retained projectile, replacing the full autopsy.

This webinar will introduce participants to the use of PMCT in the diagnosis of blunt force trauma. PMCT scan may be used to diagnose fatal trauma in certain situations, allowing an external examination with postmortem CT to supplant an autopsy, which may better honor religious and cultural requests of grieving family members.  Non-suspicious, traumatic deaths, such as motor vehicle collisions, are such an example. Additionally, PMCT often provides additional documentation of internal injuries where fatal injuries are obvious on external examination.

In the first webinar, participants will be introduced to x-ray computed tomography (CT) and some key differences between CT and traditional x-ray. The basic specifications of a CT scanner (such as bore diameter, maximum image size, and table specifications) will be introduced, with reference to their impact on whole body post-mortem scanning in particular. Basic considerations for deploying a CT scanner in a medical examiner setting (cost, personnel, space, safety) will also be discussed.
