Identification indicates that the known object is the source of, and made the questioned impression.
Higher degree of association indicates the characteristics observed exhibit strong associations between the questioned impression, and known object. However, the quality and quantity were insufficient for identification. Another object with the same class characteristics observed, is included in the population a possible sources only if it displays the same wear and randomly acquired characteristics observed in the questioned impression.
Association of class characteristics indicates the known object is a possible source of the questioned impression, and therefore could have produced the impression, another object with the same class characteristics observed, is included in the population of possible sources.
Exclusion indicates the particular object was not the source of, and did not make the impression.
Inconclusive indicates the evidence examined lacks sufficient detail for meaningful conclusion to be reached.

The growth of the volar pad slows, and the pad is overtaken by the much more rapidly growing surface skin around it.

Question 50

What affects the pattern type?

Answer 50

Size shape, and symmetry of the volar pad at the onset of primary ridge development.

Question 51

Why are friction ridges unique?

Answer 51

The principle of uniqueness is based in embryology, friction ridges develop in their definitive form on the foetus before birth. The uniqueness of the friction ridge patterns is established as a result of developmental noise, which is a biological term used to describe all of the factors acting on the developing skin ridges. There are three specific categories of contributing factors: random timing, random pressures, and random growth. Random timing refers to the timing of the start and stop of each phase of development, particularly the onset of volar pad, regression, the beginning of primary ridge development, the onset of the time of differentiation which triggers the stop of primary Ridge development, and the beginning of secondary Ridge development . Random pressures, referred to the pressures caused by the growth of neighbouring ridges, the volar pad, topography, pressures within the womb, and numerous genetic and physical pressures during growth. Every friction ridge is made up of individual Ridge units consisting of a single functional sweat pore. Random growth refers to the fact that the number of ridge units that make up of friction ridge, where the ridge starts, stops, and/or bifurcates, the location of the poor, the shape of the ridge, including height and width of the ridges are all random.

Question 52

What ensures the persistency of friction skin?

Answer 52

The configuration of a fingerprint remains unchanged throughout the lifetime of the individual. This is achieved by three specific physical attachments, which contribute to persistency: First is the adherence between the cells of the epidermis at their junctions. Skin cells are consistently lost at the surface by abrasion/exfoliation, which triggers the basal layer cells to divide, generating new cells, which are cemented together by a protein called desmosomes. These intercellular attachments ensure that the cells migrate to the surface in concert, faithfully reproducing the surface features, and the cells remain attached until they are exfoliate it at the surface. second is the adherence of the basal layer to the basement membrane, a membrane located between the top layer of the skin, epidermis, and the deep section of skin, dermis, here is the world. This attachment is achieved via interlocking fibers, and another protein called hemi desmosomes. Third, is the adherence of the basement membrane to the dermis by interlocking fibres. Ultimately friction skin is persistent, due to a combination of these physical attachments, and constant regulation of basal cell division/proliferation in the epidermidis.

Question 53

What are the five layers of the epidermis?

Answer 53

Stratum corneum - or horny layer Stratum lucidum - or hyalin layer Stratum granulosum - or granular layer Stratum spinosum - or spinous layer Stratum basale - or basal layer

Question 54

Why is the epidermis divided into five layers?

Answer 54

The layers of the epidermis are named, according to their microscopic appearance. The keratinocytes change in appearance and composition as they are pushed towards the surface as they undergo differentiation, becoming more keratinized.

Question 55

Identify each of the basic components of friction skin.

Answer 55

Sweat glands Papillary peg Friction ridge Furrow Pore Secondary Ridge Primary Ridge

Question 56

What are the effects of aging on skin?

Answer 56

The ridges begin to flatten and appear less sharp The skin loses elasticity and become susceptible to wrinkling

Question 57

What type of injury would cause a scar?

Answer 57

An injury that penetrates the skin to the basal layer can damage the epidermal basal infrastructure. The surrounding basal cells will repair the damage, but the resulting deformation will appear on the surface in the form of a scar.

Question 58

What are the three main fingerprint pattern groups?

Answer 58

Arches Loops Whorls

Question 59

Defined the arch pattern

Answer 59

Ridges enter one side of the impression and flow out the opposite side with a rise or wave in the centre

Question 60

Define the tented arch

Answer 60

Ridges enter from one side of the impression and flow out the opposite side with an upthrust in the centre

Question 61

Defined the loop pattern

Answer 61

Ridges flow from one side of the impression towards the centre and recurve then exit the same side that they entered. Loops have one delta. There are two types of loops; radial and ulnar named for the side, from which they entered the impression.

Question 62

Define the whorl pattern

Answer 62

There are four types of whorls; plain, double loop, central pocket loop, and accidental. Plain whorls have at least one ridge that makes or tends to make a complete circuit. They have two deltas if a line were drawn between the two deltas, at least one re-curving ridge would be intersected by the line. Double loops consist of 2 Separate Loop formations with two separate and distinct sets of shoulders and two deltas. Central pocket loops have two deltas, and at least one friction ridge, which makes or tends to make one complete circuit may be a spiral overall circular, or any variation of a circle. If a line were drawn between the two deltas, the line would not touch or cross any recurving ridges. An accidental consist of two different types of patterns, with the exception of the plain arch, and has two or more deltas. Can also be a pattern that conforms to none of the definitions.

Question 81

When calibrating an image using the crop method in Photoshop, should you use re-sampling?

Answer 81

No

Question 82

Are two fingerprint/friction ridge impressions of the same finger ever exactly alike?

Answer 82

No, each independent deposition does not produce the perfect replication of a previously deposited one. There are always variations in appearance or distortions of the source friction skin.

Question 83

What two fundamental principles of the skin must be understood by an examiner prior to reaching a conclusion from the examination process?

Answer 83

Uniqueness Persistency

Question 84

Describe the levels of detail, found in a friction ridge impression

Answer 84

First level detail is the overall flow of the ridges or fingerprint pattern. First level detail cannot be used to form an identification opinion, however, can be used to form an opinion of exclusion. Second level detail is the specific ridge paths, including ridge endings, and bifurcations. Second level detail can be used to form an opinion of identification or exclusion. Third level detail are the finer details such as ridge widths, pore locations, ridge shapes, scars, and incipient ridges. Third level detail cannot be present without second level detail. The presence, or lack, of third level detail does not dictate whether an opinion of identification or exclusion can be made, however, can be used to strengthen an opinion.

Question 85

Name and describe the recommended friction ridge examination method

Answer 85

ACE – V Analysis is an information gathering stage, where the examiner analyzes all visible details and features of an impression, including anatomical factors, substrate, matrix, development medium, deposition pressure, distortion, visible levels of detail, and ultimately makes an assessment of clarity and the quality/quantity of detail to make an assessment of suitability for further comparison. comparison is the side-by-side sequential comparison of all of the features observed during the analysis to determine whether the details in two impressions are in agreement. The comparison continues until all available detail in the unknown have been compared to the known. Evaluation is the formulation of a conclusion based on the analysis and comparison. The examiner makes a final determination based on whether there is agreement, and if there is sufficient uniqueness to identify. Verification is where another independent qualified examiner completes their own ACE process for the same unknown and known. The purpose of the verification is to ensure the accuracy of the original examiners final opinion.

Question 86

What three conclusions can be rendered during the evaluation stage of the process according to RCMP policy?

Answer 86

Identification Exclusion Inconclusive

Question 87

Define the conclusions for friction ridge comparisons

Answer 87

Identification - the unknown and the known impression originated from the same source. Exclusion - the unknown and the known impressions originated from different sources. Inconclusive - there is insufficient detail or information in the known or unknown to enable the examiner to form any meaningful conclusion.
