History of Hair/Fiber Analysis

Hair: Over the years crime scene investigators have been developing new ways to catch criminals. Two of the newest ways that have been discovered are done by using hair and fibers, found at the scene of the crime, to help determine who did it and with what. In 1899 Francois Goron, a forensic scientists, was able to tell the court the the victim of the murder, which he was researching, had dyed his hair before the crime took place. This important discovery led to the identity of the body and brought the case a step closer to finding the criminal. In later years forensic scientists would discover that by studying a piece of a victim you can tell whether or not metal toxicity or different types of drugs were involved.

Fiber: the study of fibers has been used in many criminal cases to catch who ever was guilty. In a trail held in 1997 the FBI was able to catch the two criminals by finding a tiny tread of the criminals jeans at the crime scene. Over the next few years crime scene investigators have been able to discover the guilty and the story behind the crime by observing tiny fibers left behind by the criminal. Tiny threads of cotton, fabric, skin, or clothing can help end a very difficult case.
