This course explores deaths caused by asphyxia, or the lack of oxygen to the brain. Asphyxia-related deaths can be present in natural, homicide, suicide, or accident investigations, and this course explores types of asphyxia and evidence associated with asphyxia-related deaths. The course also examines the role of coroners in the death investigations process and provides an overview of livor mortis, rigor mortis, hypoxia, and other symptoms that may be present at an asphyxia-related death scene. Through a variety of case studies, students will develop the skills necessary to identify deaths by asphyxia and determine the cause and manner of those deaths. The course is appropriate for investigators, officers who respond to death scenes, and individuals interested in learning basic forensic techniques.
