fibers in crime scene investigation

Fibers in crime scene investigation are tiny strands of textile material—like cotton, polyester, or wool—that can transfer between people, objects, and environments. When investigators find fibers on a suspect or at a scene, they analyze their type, color, and any unique characteristics to determine if they link a person, clothing, or item to a crime scene. Fibers can serve as physical evidence, supporting connections or distinctions between suspects and victims, and often help reconstruct events or establish contacts during the investigation process.
