ABSTRACT

Since as early as the late 1800s, scientists have used forensic nucroscopy in crime detection. Pollen typing has been used to determine the source areas for illegal shipments of marijuana. Crime scene soil samples have been used to locate the source of the material. Clothing ›bers are traced by ›ber type and special dyes. Hair can be differentiated as to species (e.g., human, dog, or cat) and distinct color, texture, and thickness. Dust found at a crime scene sometimes contains evidence as to an association with certain industrial activities.
