Fiber analysis
Fiber analysis is a method of identifying and examining fibers used by law enforcement agencies around the world to procure evidence during an investigation. Fiber analysis is also used by law enforcement agencies to place suspects at the scene of the crime. Transfer of fiber can occur during close contact with the victim or suspect. Fiber transfers can also occur during break-ins where fibers from the intruder are caught in.〔 This method is usually not used to actually pinpoint an offender in an investigation as it is not as reliable as DNA.〔
Fiber analysis does not follow any officially laid-down procedure. The most common use of fiber analysis is microscopic examination of both longitudinal
and cross sectional samples. While this is the most common method of undertaking fiber analysis, others do exist. These include the burning and solubility methods. These methods are most commonly used to reveal the identity of the fiber. Fiber analysis is usually not undertaken in university labs because of the usual lack of required solvents.
