Skin oils absorb the fingerprint dust, which is then collected on a sticky tape. Fibers can be identified by comparing physical characteristics of the unknown fiber to a database of fiber properties, including color, width, length, refractive index, and surface texture. Luminol is used to identify trace blood evidence.

Perhaps the most common type of trace evidence examiners look for at a crime scene, fingerprints are a special type of trace evidence.

A person's fingerprints are based on the patterns of skin ridges (called dermatoglyphs) on the pads of the fingers. ... The basic size, shape, and spacing of dermatoglyphs appear to be influenced by genetic factors. Studies suggest that multiple genes are involved, so the inheritance pattern is not straightforward.

The form and pattern of ridges on the surface of the skin is determined by the dermal papillae. ... Each skin ridge holds a row of pores through which sweat is released. It is a combination of these ridges and the sweat that causes a fingerprint to be left behind when the finger comes into contact with a surface.

Now look at the fingerprint from a different finger. If you compare them, you will probably see that although they might be similar, they are not identical! This is why fingerprints are such a good way of identifying people. Nobody has the same fingerprints you do-- and even each of your fingers is unique!

DNA Fingerprinting: Forensic scientists may use RFLP analysis to identify suspects based on evidence samples collected at scenes of crimes. Paternity: RFLP is also used in the determination of paternity or for tracing ancestry.
