This book describes the detailed processes and techniques essential for the scientific investigation of atrocity crimes. It includes methods for the location, evaluation, excavation, recovery, and recording of mass graves and the analysis of human remains and other evidence in order to establish the identity of victims and the cause and manner of their deaths. This volume establishes protocols and standard operating procedures to guide standards and approaches that can be used for both judicial and humanitarian contexts. The procedures for field and mortuary application are flexible and can meet specific project aims, constraints, and contexts.
