Secrets of Hair

Posted:

Hair samples are important clues when left at the scene of a crime, and now, a new technique uses human hair to help locate where a victim was before a crime occurred.          

Researchers at the University of Utah found that human hair reveals the general location where a person drank water. They analyze isotopes of hydrogen and oxygen in hair that come from water and food a person consumes.

Then they create color coded maps to pinpoint a general geographic area where that person spent time. This can help police track down criminal suspects and identify murder victims.
