Hair and fiber analysis is relatively new, dating back less than 40 years. One of the earliest criminal cases to use fiber analysis was with the abduction, rape, and murders of Sofia Silva, Kristen Lisk, and Katie Lisk (cases took place between 1996-2002). Fiber analysis proved that parts of each girls' clothing were in the culprit's car, which linked Richard Marc Evonitz to the cases. Since then fiber analysis has been further developed and has been used to solve many cases similar to these.
2. Techniques Used to ID Hair/Fiber:
One of the best ways to identify any hair or fiber is through microscopy (using a microscope to examine hair and fibers individually). Microscopy is commonly used because it is highly efficient and can give a lot of information. A single hair left by someone at a crime scene can tell the person's ethnicity (white, black, or Asian), if they are using drugs, and if their hair is real or synthetic. Fibers can be used to help identify criminals and people at the crime scene. Forensic scientists can identify what kind of clothing the criminal and victims in a crime were wearing (i.e. cotton shirt, wool sweater, etc.) This helps forensic scientists link certain people to crimes they have committed.
