Hair/Fiber Collection Techniques

A crime scene investigator (CSI) may use combs, tweezers, containers and a filtered vacuum device to collect any hair or fibers at the scene. In a rape case with a live victim, the CSI accompanies the victim to the hospital to obtain any hairs or fibers found on the victim's body during the medical examination. The CSI seals any hair or fiber evidence in separate containers for transport to the lab.If the person at the crime scene is already dead, the CSI only collects fibers that would not alter the process of determining the cause of death.
