Wherever you go, you leave a host of hidden traces. In the coming decade, an array of new forensic techniques to detect and analyse them will become available. Investigators will be able to construct photo images of your likeness from a tiny sample of DNA; your hair will tell them where you’ve been; your unique “bacterial signature” will be used as a telltale fingerprint. It's way beyond just the deduction stories of Sherlock Holmes or Dr. Salunke from CID It's the actual Science of solving crimes. Forensic Science!!
