Abstract

Microbes have long been recognised as important in fields such as medicine, ecology, and fermentation science but they have been largely ignored by forensic scientists. Microbes, particular bacteria, can impact upon forensic investigations. There is increasing evidence that humans have an extremely diverse ‘microbiome’ that may prove useful in determining ethnicity, country of origin, postmortem intervals, individual identification. Microbes are present at every crime scene and have been used as the physical evidence over the decade but there use was limited in the forensic science because of the sequencing technology of that time was typically too expensive and slow to allow enough DNA sequences to be collected to characterize diverse microbial communities. Recent advances in the studies of complex microbial communities (microbiome), have led to breakthroughs in the use of microbiome approaches for forensic science, particularly in the areas of estimating post-mortem intervals (PMIs), locating clandestine graves, and obtaining soil and skin trace evidence. Low-cost, high-throughput technologies allow us to accumulate molecular data quickly and to apply sophisticated machine-learning algorithms, building generalizable predictive models that will be useful in the criminal justice system. In particular, integrating microbiome and metabolomics data has excellent potential to advance microbial forensics
