The forensic approach to plastic bag suffocation: Case reports and review of the literature

Abstract

Death from plastic bag suffocation is unusual and rare in under-developed countries. Initially, deaths were accidental mostly of children but with time homicides, suicides and deaths in auto-erotic situations were noted. It is not always possible to discover the dynamics leading to the death especially when suicide is suspected. Often, the typical signs of asphyxia - petechial haemorrhages, facial congestion, oedema and cyanosis - are not there. The authors present two cases of plastic bag suffocation, where a multi-disciplinary approach was applied. This study reviews international literature on plastic bag suffocation, analysing the frequency of suicides, homicides and accidental deaths associated with plastic suffocation.
