A forensic overview of deaths in mountainous terrain.

Deaths at high altitudes may arise from a range of quite disparate entities including trauma (e.g. falls), environmental factors (e.g. hypothermia and hypoxia), and pre-existing medical conditions (e.g. coronary artery disease). Unique conditions include high altitude pulmonary edema (HAPE) and high altitude cerebral edema (HACE) which may contribute to lethal mechanisms or precipitate a traumatic event. Forensic issues that may arise in these cases are logistical problems due to remote locations, sometimes with failure to find a body, delay in discovery and/or repatriation, prior local autopsies being performed with embalming, and the non-specificity of pathology markers. Traumatic deaths involve blunt force impacts, falls, suffocation, crush asphyxia and hypothermia. The assessment of cases requires careful integration of the autopsy findings with the medical history of the decedent and an accurate description of their behaviour in the hours leading up to death.
