Commingled human remains are encountered in situations ranging from prehistoric ossuaries to recent mass fatality incidents. Commingled Human Remains: Methods in Recovery, Analysis, and Identification brings together tools from diverse sources within the forensic science community to offer a set of comprehensive approaches to resolving issues associated with commingled remains. This edition focuses on forensic situations, although some examples from prehistoric contexts are also addressed. Commingling of bones and other body parts is a major obstacle to individual identification that must be addressed before other forensic determinations or research can proceed. Regardless of the cause for the commingling (transportation disaster, terrorist attack, natural disaster, genocide, etc.) it is critical that the proper experts are involved and that the proper techniques are employed to achieve the greatest success in making identifications. Resolution of commingling nearly always requires consideration of multiple lines of evidence that cross the disciplinary lines of modern forensic science. The use of archaeology, DNA, and forensic anthropology are several areas that are critical in this process and these are core topics presented in Commingled Human Remains. Even a relatively "simple mass fatality event can become very complicated once body fragmentation and commingling occur. Expectations associated with all phases of the process from recovery of remains to their final identification and release to next of kin must be managed appropriately.

Dr. Adams and his team are responsible for all forensic anthropology casework in the five boroughs of New York City (Manhattan, Brooklyn, Queens, the Bronx, and Staten Island). Dr. Adams and his team are also integral players in the ongoing recovery and identification work related to the September 11, 2001 attacks of the World Trade Center. Prior to accepting the position in New York, Dr. Adams was a Forensic Anthropologist and Laboratory Manager at the Central Identification Laboratory (CIL) in Hawaii from 1997-2004. The CIL is responsible for recovering missing U.S. military personnel from remote locations across the globe and its staff utilizes forensic anthropology as a key component in the identification efforts. While with the CIL, Dr. Adams directed large-scale recovery operations in such locations as Vietnam, Cambodia, North Korea, and Papua New Guinea. Dr. Adams has served as an expert witness in Forensic Anthropology in multiple court cases, he has worked as the project osteologist on several archaeological excavations, he has authored/edited several books, and he has published numerous articles in peer-reviewed journals on topics relating primarily to forensic anthropology. He is a Diplomate of the American Board of Forensic Anthropology, a Fellow with the American Academy of Forensic Sciences, a founding board member of the Scientific Working Group for Forensic Anthropology, and a member of the Editorial Board of the Journal of Forensic Sciences.
