Q

What is the policy regarding forensic examination of major crime scene

A

1) At least 2 FI members will be involved in processing the crime scene with one investigator qualified as a specialist
2) divisional manager may approve a technician as leader of the investigation
3) It’s appropriate forensic light sources will be used to search the crime scene or exhibits for evidence
4) measurements will be taken at the crime scene for the eventual creation of a crime scene plan drawing; digital devices can be utilized
5) 3-D impressions will be photographed and cast

6) for bloodletting crime scenes the FI member will:
- conduct a visual assessment of the blood evidence
- evaluate its probative value
- consider contacting bloodstain pattern analysis and determine if attendance is required

7) BPA Can instruct the app I member at the scene to record evidence for subsequent blood stain analysis
8) Requirement of Other SME’s can be discussed through the forensic assessment centre
9) The FI member will monitor the expert at the crime scene and it sure appropriate follow up action is taken
10) When possible the FI members will be directly involved in investigators debriefing

What are the four common law requirements stipulated in R vs Mohan (1984) In order for expert opinion evidence to be heard and excepted in court

A

1) relevance
2) necessity
3) properly qualified expert
4) Absence of an exclusionary rule

Canada has taken a middle ground, sometimes allowing for the exclusion of evidence, whenever its use threatens to bring the “administration of justice” into “disrepute.”

39
Q

What are the anatomical layers of human skin

A

Epidermis

Dermis

Hypodermis

40
Q

What are the functions of the anatomical layers

A

Epidermis

  • prevents water loss through evaporation
  • acts as a receptor organ
  • provides a protective barrier for underlying tissues

Dermis

  • layer of connective tissue that provides support and nourishment for the epidermis
  • network of cells, fibers, blood vessels and gelatinous material
  • serves as a blood reserve
  • participates in sensory reception and temperature regulation

Hypodermis

  • loose connective tissue that contains a pad of adipose cells (fat)
  • Contours the body and serves as an energy reserve
  • Fibres link the epidermis to the dermis and the dermis to the hypodermis
41
Q

Where do you find volar skin

A

Underside of the hands and feet

42
Q

What are the differences between volar skin and smooth skin

A
  • smooth skin lacks friction ridges
  • smooth skin has hair and sebaceous glands
  • volar skin only has sweat glands
43
Q

What is the concentration of eccrine sweat glands on friction skin

A

2,500 to 3,000 / 2.5cm squared

The largest on the body

44
Q

What are the five layers of the epidermis

A

1) Stratum corneum
2) Stratum lucidum
3) Stratum granulosum
4) Stratum spinosum
5) Stratum basale

45
Q

Why is the epidermis divided into five layers

A

As a generates new cells in the basal layer, they are pushed towards the surface.

As the cells move toward the surface, they undergo sequential changes in chemical composition in which the cells become keratinocized during the stages of differentation

46
Q

What are the effects of ageing on skin

A

The surface ridges flatten which causes them to appear less sharp

The loss of elasticity in the dermis causes the skin to become flaccid (wrinkle)

47
Q

What type of injury cause a scar

A

Any injury that alters the basal layer template/infrastructure and

requires remarkable changes in the structure and physiology to repair the wound

48
Q

Using Alfred Hales research on the growth of friction skin, give a summary of the development of friction ridges

A
  • 3 weeks; epidermis is one cell thick
  • 6 weeks; The hand is paddle like, some volar pads are starting to appear
  • 8 weeks; The fingers have separated and elongated, thumb rotated, major flexion creases appear (palm, then fingers)
  • 10.5 to 12 weeks; volar pad regression, primary ridges form due to rapid division of basal cells, form down into dermis & up from basal layer, longest ridges form first, shorter ridges later
  • 15-17 weeks; Time of Differentation; secondary ridges begin to appear, form between exisiting ridges, primary ridges cease to dev in that area
  • 20 weeks; secondary ridges established, FR’s visible on surface, final config does not change after 20 weeks
  • 20-24 weeks; secondary ridges develop to same depth as primary ridges, 23 weeks, dermal papillae form on top of dermis between primary/secondary ridges, hugging primary, at 24 weeks entire system is mature
49
Q

What are volar pads

A

Volar pads are transient swelling of tissue called mesenchyme under the epidermis on the Palmer surface of the hands and soles of the feet of the human fetus

50
Q

What is meant by volar pad regression

A

As the volar pads slow the growth after the 10th - 11th week, Their contour becomes progressively less distinct as they are overtaken by the faster growth of the surrounding skin

51
Q

What are the three main fingerprint pattern groups

A

Whorls, Loops, Arches

52
Q

Define the arch pattern

A

ridges enter on one side of the impression, form a wave or arch and flow out the other side

53
Q

Define the tented arch pattern

A

Possess is either an arch, an upthrust, or two of the three basic characteristics of a loop

54
Q

Define the loop pattern

A

One or more ridges enter on either side of the impression, recurve, touch or pass in imaginary line from the Delta to the core and terminate on the entering side

55
Q

Define the Whorl pattern

A

Has two deltas and at least one ridge making a complete circuit.

Maybe a spiral, oval, circular or any variant of a circle

An imaginary line drawn between two deltas must touch or cross at least one of the recurving ridges within the inner pattern area

56
Q

What are the two types of impressions recorded on the C-216

A

Rolled, plain and palms

57
Q

What are the three types of fingerprints found a crime scenes

A

Latent, visible, moulded

Latent, made of sweat and sebaceous oil, invisible to the naked eye and requires additional processing to be seen

Visible, made by blood, grease, ink. or dirt, easily visible to the human eye

Molded, three-dimensional impressions and can be made by pressing your finger in fresh paint, wax, soap or tar

58
Q

How are latent fingerprints or physical evidence developed at a crime scene to be marked prior to photographing and lifting

A
  • circle the impression
  • assign a unique R or F number
  • date
  • file number
  • initials
  • directional arrow if appropriate
59
Q

1,2-Indandione-zinc Solution can be used on what type of surface

A

Most effective on porous surfaces

60
Q

Which technique is recommended for developing fingerprints on wet or damp non-porous surfaces

A

Molybdenum Disulphide

  • powder suspension
61
Q

What is the purpose of a lens

A

To gather light transmitted from an object and bring them into sharp focus on the focal plane behind the lens

62
Q

What affects exposure of an image

A

Aperture, shutter speed, ISO

63
Q

How does a digital camera Capture an image

A

The aperture opens at the front of the camera

Light enters through the lens

A CCD or CMOS sensor captures the incoming light rays turns them into electrical signals

These electrical signals are called pixels

Pixels are assigned a number based on the colour and intensity of light received

Image is stored in electronica format such as RAW, TIFF or JPEG

64
Q

What does ISO mean in digital photography

A

International standard organization

Refers to the sensitivity of light; the higher the ISO number, the more sensitive the cameras internal sensor is to light

65
Q

What is the depth of field In photography

A

Area of acceptable sharp focus in front and behind the subject in which is being focussed on

66
Q

How can you increase your depth of field

A

1) use a shorter focal length lens
2) Increase the lens to subject (move further away)
3) use a smaller aperture; F22 has greater depth of field than F4
4) Re-focus on the hyper focal point

67
Q

What is meant by white balance in digital photography

A

Colour temperature of light measured in degrees kelvin

68
Q

What is the building block of a digital image

A

Pixels (picture element)

69
Q

What is meant by resolution and Digital imaging

A

Refers to the number of pixels in an image.

Greater the number the higher the resolution

70
Q

What are you doing when calibrating an image

A

Resizing the image so that it relates to a known measurement value

71
Q

When calibrating an image using the crop method in Photoshop should you use resampling

A

No

72
Q

What does the acronym LASER mean
