As crimes and criminal methods become more sophisticated, including attempts to conceal evidence, there are cases where corpses are meticulously and thoroughly hidden. One such example is when skeletal remains are discovered within the cement structures that are being demolished for reconstruction or other purpose. However, it is difficult to detect whether a body has been buried within a cement structure prior to its demolition. In this study, animal corpses were buried in commonly used cement mortar, and the gas components generated during decomposition were examined to assess the possibility of using these components as indicator substances for locating burial sites. Among the various components detected during the decomposition of bodies buried in cement materials, dimethyl disulfide and phenol were distinctively identified. These components show promise as indicators for tracking corpses in the early stages of burial, although the influence of components originating from the surrounding environment cannot be ignored after a long period of time.
