Abstract:
Objective By analyzing the characteristics of hidden poisoning homicide cases,provide scientific references for grass-roots forensic examination and toxicological screening and provide direction for the efficient discovery of hidden or missed cases of poisoning homicide in non-natural death cases.Methods Poisoning incidents in Hunan Province from 2018 to 2023 were retrospectively analyzed and compiled using Origin and EXCEL software.Results There were a total of 149 poisoning homicide cases,with 15 occurring in urban areas(accounting for 10.1%)and 134 in rural areas(accounting for 89.9%).Out of the 46 cases that led to casualties,rodenticide poisoning was the most prevalent(accounting for 52.2%),followed by cyanide(4.3%),nitrite(4.3%),thallium(2.2%),and other forms of poisoning.These incidents were primarily concentrated in urban areas.The main way of poisoning was to mix poisons into drinking water(accounting for 28.3%),meals(26.1%),and dark or heavy seasoning(8.7%).There was no significant disparity in the gender distribution of suspects,although the number of male victims was notably higher than that of female victims.The suspects were predominantly between the ages of 19 and 45,while the victims were mostly between the ages of 46 and 60.Among the 103 cases that did not result in injury or death,99%occurred in rural areas,with more than 95%of the involved poisons included pungent pesticides or herbicides,while rodenticides accounted for the least(1.9%).Conclusion There are obvious urban-rural differences in the case occurrence areas and types of involved poisons in poisoning homicide cases.Therefore,it is imperative to focus on both urban and rural areas during the investigation and evidence collection process in suspected poisoning cases.
