Study of spectrum of various pressure abrasions caused by ligature material in violent asphyxial deaths

Abstract

From since a long time, in day to day work deaths due to pressure around the neck have been found to be a common cause of death during post mortem examination. Hanging and ligature strangulation are the two forms of violent mechanical asphyxia in which ligature mark is found. The study was conducted in department of forensic medicine and toxicology at J.L.N. Medical College, Ajmer for a period of one year i.e. from June 2019 to June 2020. During this period a total number of 104 cases of violent asphyxia death caused by pressure abrasion due to ligature were observed. In the present studytypes of ligature material used and pressure abrasion produced by them in different situation and their manner of infliction is discussed. In this study chunni (soft material) was the most common ligature material used i.e. in 32.6% cases. Fixed knot pattern was the most common (94 %of total cases). Most of the cases were occurred in closed space (room).
