This book provides an overview of Asphyxial Deaths which includes hanging, strangulation, choking, smothering, gagging, drowning, aspiration, mechanical and chemical asphyxiants, etc. Postmortem examination often leads to doubts as a clear distinction between the different type of asphyxia cannot be made easily. Forensic and physiological aspects are discussed with the help of illustrative cases. The author discusses the different aspects of asphyxia deaths and substantiates multiple case studies to establish a scientific approach that can act as a guideline to the autopsy surgeon in providing a precise opinion and clarify doubts for the judiciary involved in such criminal justice cases.
