Abstract

Hydrogen sulfide (H2S) which is a poisonous gas found either in the natural state or in industrial environments and potentially linked with accidental intoxication, can also be easily handmade. Several cases of suicide by inhaling H2S produced by mixing household products have been reported in the literature since 2009 in USA and Japan. Most of them involved short post mortem delays up to 72hours. In France, acute H2S poisoning remains rare and mostly accidental. We report the case of a 37-year-old man found at home, in an advanced stage of decomposition with a 2-month post mortem delay. As numerous warning signs about a high risk of H2S exposure were present, some precautionary measures were taken from the discovery of the cadaver to the autopsy. Toxicological analyses confirmed the presence of H2S in brain and muscle samples. This observation is the first French case with a long post mortem delay. As macroscopic findings in such cases are described to be unspecific in literature, toxicological analysis must focus on the detection and the quantification of H2S. However, due to the phenomena of post mortem drug redistribution and neo-formation, their results should be interpreted with much more caution when the post mortem delay is long. The potential increase in such voluntary-intoxication-related-deaths in France, similar to the recent Japanese and American waves of suicides, requires for forensic scientists, a good knowledge of both thanatological and toxicological pictures, and precautionary measures to adopt in such situations. © 2015 Published by Elsevier Masson SAS.
