Forensic Science Project Part II : Hair/Fiber Analysis

Reliability of hair/fiber crime scene data

Forensic scientist students need to learn about how important the reliability of hair is in crime scene and how hair and fibers are used.

Hair and fiber evidence is critical to crime scene investigators because they can know who is guilty for a crime.  During the performing of everyday activities, humans shed hair and fiber evidence from their bodies, clothes and other objects or materials of which they make contact with. Forensic analysis may be used to examine such trace evidence to summarize about the activities of persons unable or willing to explain their purpose at the crime scene. For instance if crime scene investigators wanted to reconstruct the events experienced during the crime, they can use carpet fiber form a car of a serial killer to draw connections between the serial killer and his victims, who contained the fibers on their corposes. There were two men named John Glaister and John Hicks confirmed about the accuracy that hair science was true. Many people relied on DNA testing of hairs and fibers to release them from prison. A man named James Driskell was in prison for 12 years until DNA testing of hair analysis proved him innocent for the doing a particular crime. This case shows that hair and fibers are reliable to show the innocence of a person in a court trial. Even though sometimes hair can be a great evidence for the court room, hair analysis may not tell the person’s individual identity. The federal bureau of Investigations says hair is 100%  accurate for evidence in court.

In my personal opinion I believe that the reliability of hair and fibers are important because they are the main source of getting someone out of trouble. Like for instance someone is in jail for a murder crime they know they did not commit and they have no proof that they were not at the crime scene. Your whole life depends on the hair or particular fiber that the forensic scientist collect. If the DNA does not match to that particular someone then they are free. Now if the hair or particular does link up to that person they are in some deep stuff. So I feel the reliability of hair and fibers are so important in life.
