DNA Basics: Understanding the Science and Tools Behind DNA Kinship Analysis

Virtual | February 2026

This presentation features Michelle Halsing, Assistant Laboratory Director of the Missing Persons DNA Program at the California Department of Justice. It is tailored for non-laboratory criminal justice professionals—including investigators, prosecutors, victim advocates, and program administrators—seeking to strengthen their foundational understanding of forensic DNA testing, with a particular focus on kinship analysis. The presentation offers an overview of the forensic DNA testing process, explains how DNA profiles are searched and compared within the Combined DNA Index System (CODIS), and outlines the capabilities and limitations of these tools in both investigative and judicial settings. Viewers are also introduced to the fundamental principles of forensic DNA kinship analysis, supported by discussions of real-world case applications, common testing strategies, and key considerations for interpreting laboratory reports. This resource highlights the critical role of kinship analysis in supporting missing persons investigations, unidentified human remains cases, and other complex forensic scenarios.
