Novel Psychoactive Substance Naming Conventions & Challenges

Source: US National Institute of Justice (video statements)

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.

A Comprehensive Look at LatentSleuth

Source: US National Institute of Justice (video statements)

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 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.

Post-mortem Computed Tomography of Gunshot Wounds

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.

Post-mortem Computed Tomography of Blunt Force Injury

Source: US National Institute of Justice (video statements)

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.

Post-mortem Computed Tomography Basics – Facility & Technical Aspects

Source: US National Institute of Justice (video statements)

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.

The focus of this project was the application and limitations of technology used for fire investigations. Today’s field-portable GC/MS) systems were found to provide lab-quality data for volatile hydrocarbons but the interpretation of that data proved challenging for field operators. Online access to lab experts is essential. Evidence sampling is enhanced with the use of sensitive Photoionization Detectors (PID) as a supplement to canine searches.
