Virtual Workshop Series: 3D Firearm Imaging

3D Firearm Imaging is a powerful new analytical technique that is becoming more commonplace with forensic science service providers (FSSPs) due to its ability to enhance the accuracy and reliability of ballistic evidence analysis. Despite these advantages, 3D Firearm Imaging remains underutilized because of the high costs associated with the technology, the need for specialized training, and the inertia of transitioning from traditional methods. This comprehensive workshop series aims to provide forensic practitioners with a greater understanding of the intricacies of 3D Firearm Imaging. Spanning several sessions, participants will delve into a range of critical topics, each carefully designed to enhance their expertise and proficiency in this specialized field.   

In the first session, participants will be introduced to the fundamentals of firearm imaging, becoming familiar with cutting-edge instrumentation essential for the task. Attendees will understand the features and capabilities of scanning technologies and how they capture and process images of firearms and ballistic evidence with both precision and accuracy. They will gain insight into the principles of optics, digital imaging, and image processing, understanding how these concepts are applied in forensic science practices. Moreover, participants will explore the application of control charts as a powerful tool for monitoring and maintaining the quality of imaging processes over time. This ensures consistency and reliability in forensic casework, thereby enhancing the credibility and integrity of investigative outcomes.   

Building upon this foundation, the workshop series will further explore the establishment and adherence to industry best practices and standards. Through practical examples, participants will understand the importance of consistency, accuracy, and attention to detail in firearm imaging. This session will provide an overview of validation with a focus on validating systems designed to measure and compare microscopic toolmarks on fired ammunition. Participants will also be introduced to the latest standards from the Organization of Scientific Area Committees (OSAC) and relevant documents from the 3D2 Technology Working Group (3D2TWG).   

Efficiency is paramount in forensic casework, and in session 3 participants will discover strategies to streamline workflows without compromising quality. Attendees will learn about Laboratory integrating Information Management Systems (LIMS) to enhance data management and workflow efficiency. This includes understanding the benefits and challenges of different workflow configurations, gaining insights into selecting the best approach for their specific laboratory needs.   

Finally, the workshop series will conclude by preparing participants to effectively communicate their findings in a courtroom setting. From expert testimony techniques to navigating legal considerations and challenges during cross-examination, attendees will emerge equipped with the skills and confidence needed to convey their expertise with clarity and credibility.
