A Case of Homicidal Death from Poisoning with Pure Carbon Monoxide Gas

Death from poisoning of carbon monoxide(CO)gas is common in cases of suicide and/or accident.It is rare to be reported of a murder using pure CO gas in China or abroad.This paper narrates a homicidal case where a bottle of pure CO gas was adopted to bring the victim into death,such a covert and seldom-seen homicide.In order to avoid legal punishment,the suspect even falsifi ed the crime scene,resulting in diffi culties for the investigators.Through careful investigation into the crime scene plus autopsy,evidential material extraction and examination,together with scrutinous survey and interview,the death cause was finally clarifi ed and the suspect was identifi ed,eventually having the crime process fully reconstructed.Summarization and analysis were here made on the key points and diffi culties in solving the case,with purpose to provide assistance and reference to the peers.
