Document Summary

The trace evidence transferred between individuals and objects during the commission of a crime, if recovered, often corroborates other evidence developed during the course of the investigation. Any review of the forensic aspects of hair examination must start with the observation that it is not yet possible to individualize a human hair to any single head or body through it morphology or structural characteristics. Partial success to individualizing a human from a strand of hair has been achieved by isolating and characterizing the dna present in the hair. The importance of hair at a crime scene cannot be over emphasized. Its removal from the body often denotes physical contact between a victim and perpetrator and hence a crime of a serious or violent nature. When hair is properly collected/preserved and sent to the crime lab along with enough standard/reference samples, it can provide a strong corroborative evidence for placing an individual at a crime site.
