Forensic Microbiomics and Trace Microbial Evidence: Molecular Innovations for Linking Suspects, Objects, and Environments

Microbial forensics has beneficial characteristics for investigating crimes. Law and order are fundamental to any nation and carry significant responsibilities. Failure in this domain may result in wrongful convictions or the guilty remaining free. Key duties include managing criminal cases and addressing threats to public order. While identifying the culprit, establishing their connection to the crime is paramount. Since legal systems require evidence for conviction, law enforcement increasingly relies on advancing scientific methods to meet this need. For example, in this case, after applying conventional techniques like DNA analysis and fingerprinting, a new technique, such as microbial forensics or fingerprints, can be applied. Trace evidence can be in the form of microbial fingerprints, and this evidence can play an important role in solving the crime. Microbial communities are dense and active in living and non-living things and in the environment. The classification and roles of these bacterial populations could be used as markers. The distinction between forensic samples is achievable because there is a diversity of microbial communities found in the human body from one location to another, and even in identical twins. The specific microbiome, which can be found on the skin or in specific body areas, may precisely identify the suspect’s connection with the crime scene for the purposes of human identification. This paper discusses the objects and latest advancements in the science of microbial forensics and their significance within the law enforcement process.
