Fingerprint Patterns MinutiaeFingerprint Anatomy Identificatio n Criteria Lifting Latent Prints

These are the three major classes of fingerprint patterns. Who is loops, arches and whorls?

This is the most common ridge pattern. What is a loop?

This is the number of deltas found in a typical arch pattern. What is zero?

What is a whorl?

What is a double loop?

There are approximately this many ridge characteristics in the average fingerprint. What is 150?

What is a ridge ending?

What is a bifurcation?

What is a dot?

What is a lake?

A person’s fingerprints are formed at this time. What is during fetal development?

This is the purpose of friction skin ridges. What is to get a firmer grip and resist slippage?

The pores of the sweat gland are located in this. What are the skin ridges?

In order to permanently damage the fingerprint, one must damage this layer of skin. What is the dermal papillae?

Sweat glands on the friction ridges do not produce this molecule, which is common in all other sweat glands. What is oil?

The fingerprint classification system that classifies prints based on the number and location of whorls is called this. What is the Henry system?

This is what determines the minimum number of ridge characteristics needed to match two fingerprints What is the experience of the investigator?

The computerized system for storing fingerprints is known as this. What is AFIS?

These are two of the Daubert criteria that fingerprint analysis does not meet. What are it does not have any standards and you cannot determine its potential rate of error?

This man had an almost exact double who had the same Bertillion measurements as him. Who was Will West?

Prints that are not readily visible are known as this. What is latent?

Prints impressed into a bar of soap are known as this. What are plastic prints?

Sublimation occurs with the use of this lifting method. What is iodine fuming?

Ninhydrin is used to detect this type molecule in latent fingerprints. What are amino acids?

Superglue fuming is not suitable for this type of surface. What is a porous surface?

This is an example of a porous surface. What is paper, wood, cloth, etc.?

This fingerprinting method produces a temporary orange/brown print. What is iodine fuming?

This chemical treatment produces a white-appearing permanent fingerprint What is Superglue fuming?

This fingerprinting method produces a permanent purplish print. What is ninhydrin?

These two fingerprinting methods are used on porous surfaces. What are iodine fuming and ninhydrin?
