"Unidentified remains" refer to human remains that have not been identified or matched to a known individual. This situation can arise from various circumstances, such as accidents, natural disasters, or criminal activities. Forensic experts often use techniques like DNA analysis and dental records to help identify these remains. When remains are found, authorities typically conduct investigations to determine the identity of the deceased. If identification is not possible, the case may remain open for years, and the remains may be stored in a morgue or a forensic facility. Organizations like NamUs assist in the identification process by providing resources and databases for missing persons.
