ALREADY GRADED A+
This is a latent print development technique that employs finely powdered
lead to visually record latent print images: - ANSWERS-X-Ray
Photographing a latent print prior to lifting: - ANSWERS-Preserves the latent
image in the event of loss or destruction in the lifting
Three types of lifting devices are commonly used to lift powdered latents: -
ANSWERS-1. Rubber lifters
2. Lifting tape
3. Hinge lifters
Rubber lifters are not commonly used as lifting tape and hinge lifters, but
they are more versatile. Rubber lifters are particularly useful when lifting
latent prints from: - ANSWERS-Curved Surfaces
,Lifts made with transparent tapes and lifters can be compared directly with
inked impressions, whereas opaque lifters must be: - ANSWERS-Reversed
If two or more simultaneous fingerprints are developed in a group, the best
procedure is to lift: - ANSWERS-The impressions as a group
A latent print itself is not removable from a surface by the lifting process. The
oils and moisture simply hold powder grains, which are in turn picked up by
the adhesive tape. A powder and not the latent image is lifted. - ANSWERS-If
the process is repeated, each lift becomes progressively weaker.
Iodine developed latent prints can be accelerated by exposure to: -
ANSWERS-Sunlight
Silicone rubber casting provides the best technique for accurately recording
and permanently preserving: - ANSWERS-Plastic fingerprint impressions
Latent fingerprints on ______ are about the most difficult or an examiner to
detect and develop - ANSWERS-Cloth
The correct procedure to recover latent prints on dusty surfaces is: -
ANSWERS-Proper use of lighting and photography
Latent prints etched in metal: - ANSWERS-Cannot normally be developed
further and must be photographed as they appear.
,The best technique for developing latent fingerprints on plastic is: -
ANSWERS-Magnetic powders
This technique has been known to develop print impressions on human skin -
ANSWERS-Iodine
Gentian violet is a dye which stains fatty constituents of sebaceous sweat
producing an intense purple image. It is very effective for the development of
latent fingerprints on... - ANSWERS-Adhesive surface of adhesive tapes
Alternative process names for Gentian Violet - ANSWERS-1. Crystal Violet
2. Methyl Violet
Alternative process name for Amido Black - ANSWERS-Naphthalene Black
Iodine vapour is physically absorbed by latent fingerprint deposits and often
fades unless fixed. What color image is formed using iodine vapour? -
ANSWERS-Brown
Gentian Violet can interfere with the forensic examination for: - ANSWERS-1.
Handwriting
2. Body fluids
3. Ink
Ninhydrin is a general purpose fingerprint reagent for paper and some other
porous surfaces. What component of a fingerprint deposit does it react with?
- ANSWERS-Amino Acids
, How long does it generally take for Ninhydrin treated prints to naturally, fully
develop - ANSWERS-Several weeks
The development of Ninhydrin treated prints may be accelerated with the use
of? - ANSWERS-Heating and Humidification
Ninhydrin which uses a Freon solvent virtually eliminates the following
problem when processing porous materials for latent prints? - ANSWERS-Ink
running
Ninhydrin may be applied using what methods? - ANSWERS-1. Dipping
2. Brushing
3. Spraying
Physical Developer (PD) is what kind of aqueous reagent? - ANSWERS-Silver-
based
Physical Developer reacts with components of sebaceous sweat to form what
colored deposit? - ANSWERS-Grey-silver
Physical Developer is a very effective reagent for developing latent
fingerprints on paper which has been: - ANSWERS-Wetted
These flake powders have been shown to be more sensitive than most other
types of powders - ANSWERS-Aluminum
