Fighting crime with fiber research
A new chemical process developed by researchers from N.C. State University will help forensic analysts identify and match the dyes used on small fiber samples. Investigators can use this process to conclusively prove if two fibers share specific dyes or impurities, therefore matching trace evidence samples of fibers in criminal court cases. Trace evidence is “anything involved in a crime that can be transferred between people, objects or the environment, such as hair or dirt,” and is a big part in major investigations. Thomas A. Dow, a professor in mechanical engineering, is also involved with furthering the project and is working on creating a small machine that will allow investigators to use this process to perform chemical analysis of fibers in the field.
