Module 2-3 Personal Identification Techniques Flashcards
It is the epedirmal hairless skin found in the central/lower surface of the hands and feet covered with minute ridges and furrows and without pigment and coloring layers.
Friction Skin
It is the component of the friction skin that actually formed the fingerprint impression.
Ridge Surface
This is the tiny opening or the tiny white dots.
Sweat Pores
This is the passage way of sweat.
Sweat Duct
This is the producers of sweat.
Sweat Glands
Are naturally raised raised strips of skin found in the Palmar side of our fingers and thumbs in which the fingerprint patters are formed.
Ridges
Fingerprints begun to develop around the 10th week and are complete by the end of the 4th month of pregnancy.
Formation
It says that even identical twins don’t have identical fingerprints.
Uniqueness
Factors that affect the development of friction ridges.
Genetic factors and environment inside the wound
A persons fingerprints will remain the same throughout thier life.
Persistence
It is the destruction of the friction skin can either be temporary or permanent.
Ridge Destruction
This occurs when only the epidermis layer of the friction skin has been damage.
Temporary Destruction
It can be injected to the friction skin due to damage to the dermis layer.
Permanent Damage
What causes ridge destruction?
It caused by manual works, skin diseases, warts, skin ulcers, burn, and scars.
What causes of no fingerprints on humans?
It caused by permanent damage and genetic condition.
It is a disorder to a gene mutation on chromosome 4 that causes a person to have no fingerprints.
Adermatoglyphia (Immigration delay disease)
What are the three genetic conditions?
- Adermatoglyphia
- Dermatopathia Pigmentosa Reticularis (DPR)
- Naegeli-Franceschetti Jadasshon Syndrome (NFJS)
They are the ones noted to be the first user of fingerprints for their symbolism in the early part of their rituals until they utilize it in the signing of contracts for those who were illiterate.
China
In China they called fingerprints?
Hua chi
He is the first Filipino fingerprint technician employed by Phillipines Constabulary.
Generoso Reyes
She is the first Filipina fingerprint technician.
Isabela Bernales
Gave the first examination in fingerprinting in 1927 and Agustin Patricio of the Philippines topped the examination.
Capt. Thomas Dugan (New York Police Dept.) and Flabiana Guerero (FBI Washington)
First conviction base on fingerprint and leading case decision in the Philippines Jurisprudence.
People of the Philippines vs. Marciano Medina y Diokno
The first to state that friction ridges are never duplicated in two persons.
Johann Christoph Andreas Mayer
He discovered the two layers of the skin the dermis (inner layer) and the epidermis (outer layer).
Marcelo Malpighi
He is known as the Grandfather of Fingerprint.
Marcelo Malpighi
He established a certain role for classification and be able to identify 9 types of pattern although never associated to identification.
Johannes Evangelista Purkenji
He is the father of dactyloscopy
Johannes Evangelista Purkenji
The first to advocate the use of fingerprints as substitute for signatures among Indian natives to avoid impersonations.
Sir William Herschel
He wrote the English journal “Nature Dealing with latent prints found at the scene of the crime”. He claimed that the impression would provide positive identification of offenders when apprehended.
Dr. Henry Faulds
He discovered the three general classifications of fingerprints patterns; arches, loops, and whorls established a Civil Bureau of Personal Identification.
Francis Galton
He developed the Henry System of Classification at Scotland Yard which was accepted by almost all English speaking country. He is known as father of fingerprint.
Sir Edward Richard Henry
US notorious public enemy no. 1 who tried to remove his fingerprints with acid but failed. Post-mortem fingerprints taken after FBI shot him proved that he was indeed Dillenger.
John Dillenger
Gained fame as the “man without fingerprints “. He was also known as the name Roscoe Pitts
Robert James Pitts
He performed painful experiments on themselves by burning their fingerprints with boiling water, hot oil and hot metal. Yo
Locard and Witkowsji of Lyons
It refers to the details of ridge structures, formations and elements which differentiate from one fingerprint to another and impart individuality to each print.
Ridge Characteristics
A rudge formation characterized by a closed angular end and serves as a point of convergence ( meeting of two ridges that were previously running side by side)
Converging ridge
Two ridges flowing side by side, one ridge going one way and the other ridge going another way.
Diverging ridges
A single ridge that divide into two but does not remain open and meet at a certain point to form the original single ridge
Enclosure (lake or eyelet) ridge
These are enclosed within the pattern area.
Focal points
A recording ridge which is complete in its shoulder and free from any appendage.
Sufficient recurve
It usually runs longitudinally along the length of the finger.
Crease
A permatent crease in the skin at the knuckles which permits the skin to flex when the finger is extended.
Flexure line
It is the first level of detail used in the identification process.
Pattern
(T/F)
An arch pattern don’t have a Delta and core.
True
What are the two types of tented arch?
Upthrust type and angular type
(T/F)
In arch pattern the tracing and counting of ridges is not applicable.
True
(T/F)
In loop pattern there is only one Delta and one core.
True
(T/F)
In loop pattern, ridge counting is applicable but ridge tracing is not applicable.
True
The inner bone of the forearm that runs to the wrist on the side where the thumb is located.
Radial bone
A loop in which the downward slope or the slanting ridges runs towards the direction of the little finger
Ulnar loop
A loop in which the downward slope or the slanting ridges runs towards the direction of the thumb.
Radial loop
The bone running to the wrist located or situated on the little finger.
Ulnar bone
A pattern consisting of two deltas and which at least one ridge makes a turn through one complete circuit.
Plain whorl
A pattern which possesses two deltas with core or more ridges forming a complete circuit which may be oval, spiral, circular or any variant of a circle.
Central pocket loop whorl
A pattern consisting of two separate and distinct loop formations with set of shoulders and two deltas.
Double loop whorl
A pattern consisting of combination of two different types of a pattern such as loop and a whorl.
Accidental whorl
