Document Summary

Transferred trace evidence can corroborate other evidence developed during the course of an investigation if recovered. Appendage of the skin that grows out of the hair follicle. Not yet possible to individualize a human hair to any single head/body through its morphology. Removal from body denotes physical contact between a victim and perpetrator -> crime of a serious/violent nature. Can provide corroborative evidence for placing an individual at a crime site. Resistance to chemical decomposition + ability to retain structural features over a long period of time. Length of a hair extends from its root/bulb embedded in the hair follicle, continues into the shaft, and terminates at the tip end. Shaft is composed of 3 layers + is subjected to the most intense examination. Cuticle: scale structure covering the exterior of the hair. Formed by overlapping scales that always point toward the tip end of each hair.
