| Summary: | Carbon dioxide (CO2) is an endogenous molecule produced by cellular respiration and therefore present in our body and in the atmosphere. It is known that, at high levels, CO2 causes fatal toxic effects. The production of CO2 can prove particularly dangerous in closed and unventilated environments. Although some cases of death due to CO2 are described in forensic literature, today this diagnosis of CO2 intoxication on cadaver is still a challenge as it is a volatile endogenous molecule and strongly increased after death due to anoxia. In this paper, we describe six cases of simultaneous CO2 intoxications which was caused by a fermentation of grape must in a closed environment. Four people died while the other two were rescued. Scene investigation with measurement of environmental gas levels using sensors was performed. Autopsies were carried out with toxicological investigations and histopathological analyses. Finally, a review of the scientific literature on deaths related to fermenting grape gas was carried out. The results demonstrated toxic levels of CO2 at the scene. The corpses showed initial transformative phenomena such as skin discoloration and slippage, while toxicological investigations demonstrated a peak of HbCO2 (carbaminohemoglobin) with alcohol positivity in the blood of the deceased subjects. Histopathological investigations showed must yeasts (Saccharomyces) in the pulmonary alveoli. The paper reports the procedures performed proposing the introduction of new experimental investigations for the post-mortem diagnosis of CO2 intoxication with a forensic diagnostic protocol. |
