First Impression
Fingerprints are this type of evidence:
Individual
This is the rarest type of finger print that occurs in only 5% of people. The ridge patterns form a wave-like pattern.
Arch
Distinguishing characteristics found in ridge patters are known as:
Minutiae
This is the most commonly used technique to reveal latent prints.
Dusting
A pair of identical twins are convicted of a crime. Will they have the same fingerprints?
No
A fingerprint that is invisible to the naked eye.
Latent Print
This type of fingerprint is defined by a central core with one ridge forming a complete spiral.
Whorl
How many deltas does a whorl print have?
This technique is used to preserve visible or latent prints that have been dusted.
Lifting
Fingerprints form at this point in a person's life.
In the womb
These prints are visible to the naked eye and are formed when blood, ink, paint, or dirt is transferred to a surface.
Patent
This type of fingerprint is the most common and must have one or more ridges entering and exiting from the same side.
Loop
Two parallel ridges united by a perpendicular ridge in the center.
Bridge
This chemical turns latent prints grey.
Silver Nitrate
What is the function of our fingerprint ridges?
To grip
This type of fingerprint leaves behind a 3D mold of the ridges.
Plastic
If you find a radial loop on a surface, it will most likely come from this hand:
Left
A straight ridge that branches off into two directions.
Bifurcation
This chemical reacts with the amino acids in fingerprint residues, causing the latent print to turn pink or purple.
Ninhydrin
A straight ridge that has a circular center.
Enclosure
Even if prints cannot be seen with the naked eye, this leaves behind traces in the form of latent prints.
Glands
This variation of the arch print has a more steep ridge incline.
Tented
A ridge that is as long as it is wide.
Dot
These superglue flumes react with water and other fingerprint constituents to form a hard, whitish deposit.
Cyanoacrylate
A ridge that splits off into three branches.
Trifurcation
