Water is such a powerful life force, it can even be used to help determine where the unidentified once lived. This kind of examination is called Isotope Analysis and it is
a great tool toward being able to indicate regions of origin for unidentified John and Jane Does.
In Isotope Analysis, bone and teeth samples are analyzed for stable isotopes of carbon, oxygen and nitrogen values which have been incorporated both during adolescence and over a lifetime. These stable isotopes can even determine dietary input!
This article by Frank Stanfield references how Isotope Analysis is being used in the case of "Julie Doe," a transgender 1988 homicide victim. "Julie Doe" is on the list of cases currently being undertaken by the DNA Doe Project.
