Homicides in which the victims are first subdued with a chemical asphyxiant rare unusual and quite rare. We report three cases in which victims were first overcome by ether containing compounds and then killed by other means of asphyxiation. The ether containing compounds used in these three cases were readily available commercial products. In two cases, the distinctive spectra of the volatile compounds in the decedents' blood, from the gas chromatograph and from the gas chromatograph/mass spectrometer, were compared with suspect ether containing products recovered during the scene investigations. In one case, an identical match was obtained. In the other case, the chromatographic spectra differed slightly from the compounds found at the scene, but the difference was explainable by metabolic breakdown of the compounds in vivo.
受害者首先被化学窒息剂制服的杀人案件罕见、不寻常且极为少见。我们报告三起案件，受害者先是被含醚化合物制服，随后被其他窒息手段杀害。这三起案件中使用的含醚化合物均为容易获取的商业产品。在两起案件中，将死者血液中挥发性化合物的独特光谱，通过气相色谱仪以及气相色谱/质谱联用仪得出的结果，与现场勘查中找到的可疑含醚产品进行了对比。在其中一起案件中，获得了完全匹配的结果。在另一起案件中，色谱光谱与现场发现的化合物略有不同，但这种差异可以通过化合物在体内的代谢分解来解释。
