Autoerotic asphyxia is a form of deviant sexual behavior that seeks sexual gratification by means of manipulation with one's own body resulting in asphyxia, and may sometimes turn out to be fatal. Autoerotic fatalities involving autoerotic asphyxia are divided into two groups: "typical" autoerotic fatalities involve mechanical compression of the neck, chest or abdomen, whereas "atypical" autoeroticism involves sexual self-stimulation by other means. Cases where asphyxiophilic behavior is accompanied by volatile substance abuse are reported to be rather rare, but may involve a high risk of fatal results. This paper presents a case of accidental "atypical" autoeroticism involving victim's abuse of toluene, which, combined with asphyxiophilic airway occlusion, led to death. For the sake of comprehensiveness, both a verbal description and a schematic representation of the major metabolic pathways of acute and chronic abuse metabolic markers is provided.

Fatalities due to gas intoxication are rare in routine forensic casework. The most common gas is carbon monoxide, with other gases (ammonia, methane, propane and butane, carbon dioxide, hydrogen sulfide) encountered only very rarely. In this report, we describe the accidental death of two maintenance workers who were found in the silage pit at a biogas plant. The autopsy revealed signs of asphyxia in both the deceased. Analysis of the gaseous mixtures in the tank using an infrared gas analyzer showed slightly elevated concentrations of carbon dioxide. Toxicological examination of the blood of both the deceased using gas chromatography with a flame ionization detector, spectrophotometry and liquid chromatography-mass spectrometry did not detect any toxicologically significant substance that would explain the sudden collapse. Both the autopsy and the toxicology analyses suggest CO2 intoxication as the most likely cause for the collapse of the two men, which then led to sudden asphyxia.
