Quiz Three
Pattern diversity principle is defined as
the variations in combinations of blood volumes and forces acting on those volumes lead to recognizable classes of patterns
T/F: Latent, Patent, and plastic are all general types of fingerprints
true
T/F: SPR is a liquid with molydenum disulfide suspended in it that is effective for wet surfaces
true
T/F: The primary reason for using super glue fuming technique is it stabilizes the latent print
true
T/F: The theory of Blood pattern analysis is blood as a fluid responds to forces in a predictable manner
true
T/F: directionality defines the direction a droplet was moving at the time it struck a surface
true
T/F: the range determinations offered by the medical examiner are all based on the absence or presence of soot, stippling and burning in or around the wound
true
T/F: the two primary categories of the bloodstain pattern taxonomy are spatter and no spatter stains
true
A fingerprint that is actually a 3D Impression made in some malleable media (eg wax)
plastic
Which of the below is an example of basic surface types
porous surface, nonporous rough, nonporous smooth, special conditions
T/F: Latent prints are typical mindset of fingerprints, depositors of oils leaving a nearly invisible deposit that must be enhanced
True
T/F: The point where the reverse vectors of several related spatter stains converge on a surface
True
T/F: the effective documentation of bullet defects so important because they define specific events in the scene, so knowing position and orientation of the evidence in the scene can be critical to any conclusions drawn from the evidence.
True
T/F: AFIS is a computerized system that removed any need for human involvement in fingerprint identification
Ture
T/F: Fluorescent fingerprint powder provides greater contrast between the background and the latent print. It is effective on multicolored surfaces
Ture
Fingerprint identification is made by comparing ___ in the known fingerprint with the unknown fingerprint sample
arches, loops, and whorls
basic scene fingerprinting techniques include
brush and powder, superglue fuming, small particle reagent (SPR), and rough surface casting gel or silicon
which term applies to the projectile fired from a handgun
bullet
T/F: Identification of a firearm to a bullet is accomplished by evaluating the lands and grooves
false
T/F: Where each and every bullet defect is located is not of significant interest and bullet holes do not have to be located in the sketch and crime scene mapping data
false
T/F: once a fingerprint has been developed it is called a known
false
which is part of the basic steps used to conduct a bloodstain pattern analysis
familiarize yourself with the scene, identify all discrete patterns, categorize the patterns
internal ballistics is conducted by
forensic firearms examiner
terminal ballistics is conducted by
forensic pathologist
Adding machine paper technique is best used on
human skin
