Tenants of the duplex house complained to the landlord that their toilets had been backing up for a week. The complaints initiated a search for the septic tank which was located about 5 feet from the north wall of the house. The discovery of a body in the septic tank required innovative solutions by the police and the medical examiner. Almost the entire skeleton was recovered, and the skeleton had features consistent with a white adult male. Radiographs disclosed tiny radiopaque fragments embedded in the medullary trabeculae around multiple cortical defects in several bones. Projectile fragments recovered from clothing further supported a conclusion that death was due to multiple gunshot wounds. A forensic odontologist documented enough matching points of comparison between distinctive features in the skull and the teeth to establish identification with reasonable medical certainty. Main aspects of the septic tank system are summarized, including functional theory, physical design and components, and use and maintenance. Basic principles applicable to the excavation and examination of human skeletal remains are discussed, and a general approach to victim identification is described. 6 references and 2 figures
