Microbial Forensics

A crucial part of forensic investigation is identifying evidence at a crime scene, including witnesses, fingerprints, DNA, and trace evidence. Trace evidence, like dirt from a suspect's shoe or fibers from their clothing, can link them to the crime scene.

Recently, investigators have explored using microbiomes for identification. Humans shed millions of unique microbial cells into their environment, making microbes a promising tool for tracking and profiling, similar to fingerprints and DNA. This could become a valuable resource in forensic science.
