Types of Cases in which Fiber and Hair may be of Value As Evidence

Many crimes involve direct physical contact between victim and suspect. Whenever such contact occurs, there is frequently an inadvertent transfer of microscopic evidence. This evidence transfer is usually hairs and fibers. However, this type of evidence, which can be microscopic in form, may often be overlooked by investigating officers because it is not easily observed. Even though the most commonly encountered fibers are white and/or blue polyester, cotton, or blends of these, this type of
evidence should be collected and submitted for evaluation.

Types of Cases in which Fiber and Hair may be of Value as Evidence

Assault/Rape/Homicide - these types of crimes usually involve personal contact of some sort.
Therefore, fibers and hairs may be interchanged between victim and suspect and/or their respective environments and apparel. Weapons and fingernail scrapings also may be important sources of fiber evidence. Bindings, such as rope, may also leave distinct fibers if a person was tied up.

Burglary - Clothing fibers will frequently be found at the point where the burglar may have been forced to crawl through a window or other opening. If no head covering was used, hair may also be found.

Hit-and-Run - Due to the forceful contact between victim and automobile, clothing fibers and hair can generally be found adhering to the fenders, grill, door handles, or parts of the undercarriage. Fabric impression patterns may also be observed on surfaces with which the fabric may have impacted.
