Abstract

Forensic stable isotope analysis of human hair aims to assist law enforcement in the identification process by providing information on an individual’s geographic life history. The variations in isotope abundance due to fractionation of hydrogen, oxygen, carbon, and nitrogen reflect the isotopic make-up of water and food a person consumes. Utilizing space and time variations in isotope ratios, law enforcement can concentrate their efforts in specific regions using Isotope Ratio Mass Spectrometry. This is particularly useful in cases where the body is deliberately dismembered or too compromised where the lack of distinguishing features hinder identification.
