In a mass fatality incident, correct victim identification is essential to satisfy humanitarian considerations, meet civil and criminal investigative needs, and identify victim perpetrators. This Special Report provides medical examiners/coroners with guidelines for preparing the portion of the disaster plan concerned with victim identification and summarizes the victim identification process for other first responders. It discusses the integration of the medical examiner/coroner into the initial response process, and presents the roles of various forensic disciplines (including forensic anthropology, radiology, odontology, fingerprinting, and DNA analysis) in victim identification. This guide represents the experience of dozens of Federal, State, international, and private forensic experts who took part in the Technical Working Group for Mass Fatality Forensic Identification.
