What is the role of fibers as a source of evidence in forensic investigations?

The ability of various types of fibers to hold onto signs of human contact made them an invaluable tool for investigations even before "DNA Testing" became widely available.

Because they are used in almost everything, from upholstery to decorations to clothing, they are also frequently found at crime scenes. Although they may be used directly as specific materials for forensic purposes, the relationship between them and human remains can be greatly enhanced.

Fibers can serve as crucial evidence in forensic investigations by providing valuable information about potential suspects, crime scenes, or victims. They can be transferred between individuals or locations during a crime, such as clothing fibers left behind during a struggle or carpet fibers from a crime scene. Analyzing the type, color, composition, and microscopic characteristics of fibers can help link suspects to crime scenes or connect different crime scenes together. Additionally, fibers can provide insights into the type of materials involved in a crime, aiding investigators in reconstructing events and identifying potential weapons or tools used.
