Abstract:
In the process of murder investigation,it is of great significance to find the discarded and buried human remains accurately.The main methods of searching for human remains include human vi-sual search,aerial detection,geophysical technology,remote imaging technology and canine olfactory search technique.Canine olfactory search for human remains is a recognized time-effective and non-invasive search method,making dogs the most valuable search tool in forensic investigation.By sys-tematically reviewing and summarizing relevant literature,and based on the theory of volatile organic compound produced by the decomposition of human remains,this paper explores the basic principle of the canine olfactory search technique for human remains.This paper also reviews the application of training canine search technique for human remains in forensic investigation by using human blood,tissue,cadaver putrefying fluid and odor substitutes as sniffing sources.The application prospect of canine olfactory search for human remains was prospected from the perspectives of detection of vola-tile organic compound during cadaver decay,development of odor substitutes and adsorption devices,and technology tactics used in canine training and use,to provide references for the relevant research of canine olfactory search for human remains in China.
