Fibers are important to forensics because they serve as trace evidence that can link suspects, victims, and crime scenes. They can be transferred during physical contact, such as in a struggle or through mere contact with objects, and thus provide valuable information about where a person has been or with whom they have come into contact. Analysis of fibers can help reconstruct events, establish timelines, and sometimes identify the source or origin of the fiber, whether it is from clothing, upholstery, carpet, or other textiles. Although fiber evidence is not as uniquely discriminatory as DNA, it is very useful for showing associations and physical contact in criminal investigations. For example, fibers from a victim found on a suspect's clothing can suggest recent contact, supporting the investigation's narrative. Fiber evidence has played important roles in high-profile cases by linking suspects to victims and crime scenes, showing its significance in forensic science.
