A Case of Asphyxial Death Caused by Using Plastic Ties to Strangle the Neck
This article introduces a case of asphyxial death caused by using plastic ties to tie(strangle)the neck.The deceased was a teenage female who lost contact with her family while climbing the mountain alone.The body was found on the mountain the next day.The deceased's hands,feet,and neck were tied with plastic ties.After removing the ties,a 0.8cm wide circular closed cable groove was exposed on the neck.Mild congestion on the face of the deceased,patchy bleeding on the bulbar conjunctiva,more mushroom-like foam in the mouth,nose and trachea,no significant bleeding under the neck sulcus and muscles;Forensic histopathology revealed a decrease in the stratum corneum of the cervical sulcus skin,narrowing of cell spacing,elongation of cells and nuclei,pulmonary congestion and bleeding,focal interstitial bleeding in the heart,wave like changes in some myocardial fibers,edema of brain cells,and hypoxic changes in neurons;No toxic substances such as ethanol,barbital,phenobarbital,scobarbital,and tetramine were detected in the physical and chemical tests.Based on the above analysis,the deceased was found to have died from asphyxia due to external compression of the neck caused by plasticties.According to the analysis of signs such as more mushroom-like foam in the mouth,nose and trachea of the deceased,congestion in the face and mild bleeding,the neck bandage failed to completely close bilateral carotid arteries,veins and trachea,indicating that the death process of the deceased lasted for a long time.In addition,there is a difference of several hours between the estimated time of death using indicators such as the degree of digestion of gastric contents in this case and the time of crime confessed by the suspect.Through reviewing relevant literature,it was found that there is a significant error in using the degree of digestion of gastric contents to estimate the time of death in individual cases,which is related to factors such as personal constitution,on-site environment,and dietary conditions,It is suggested that forensic colleagues should not overly rely on a single indicator when inferring the time of death using early corpse phenomena.Instead,they should analyze factors such as the case,on-site environment,dietary conditions,and personal physique as comprehensively as possible.
