A Close Look at 3D Microscopy for Firearms Identification
Firearms identification is undergoing a major change in capability with the adoption of optical topography, which provides a 3D view of the surface of a bullet or cartridge case to capture the full range of subclass and individual characteristics.

Two-Pronged Study of Bullets Fired by Consecutively Rifled Barrels
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
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
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.

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.
