Forensics Chapter 4 Questions with Correct Answers |New Update 100% Verified By Experts
The skeletonized perimeter of a bloodstain can be used to interpret: The source of the
bloodstain, the time that elapsed between deposition of the stain and alteration of the stain.
A blood droplet deposited at an angle of impact of about 90 degrees°(directly vertical to the
surface) will: Be approximately circular in shape
The velocity at which blood strikes a surface is not useful to describe the specific events that
produced the spatter pattern. (T/F) True
Void spatter is the most common type of bloodstain pattern found at a crime scene. (T/F)
False
Setting up squares of known dimension over the entire pattern describes the: Grid Method
The direction of a ________ may show movements of objects or bodies while the pattern was
still forming or after the blood has dried. Flow Pattern
Gunshot exit wounds commonly produce medium-velocity spatter, while explosions produce
high−velocity Spatter. (T/F) False
The removal of an object or surface that was located between the origin of blood and the target
surface during the bloodstain deposition leaves behind: A void
Droplets of ________ are very small. They may not travel far and could be overlooked. High
velocity splatter
Crime scene reconstruction requires the piecing together of: Accounts given by the
witnesses and suspects, the story told by evidence recovered at the crime scene and the input
from the medical examiner.
, The intersection of straight lines through the long axis of several individual bloodstains in an
impact spatter pattern illustrates the ________ of the pattern. Area of convergence
Widely spaced bloody shoeprints with satellite spatter between the shoeprints were likely
deposited by an individual who was: Running
The location of injury, the size of the wound created, the distance between the victim and the
muzzle of the weapon all affect the amount of backward spatter that occurs. (T/F) True
What should one surmise if a flow found on an object or body does not appear consistent with
the direction of gravity? The object or body was moved after the blood had dried.
An impact pattern consisting of large separate drops with diameters of 5 millimeters is: Low
velocity splatter
If a murder victim's blood is found in the muzzle of a firearm: It can be concluded that the
firearm was present during injury to the victim.
The less blood on an object, the smaller the stains produced. (T/F) True
Physical evidence that can be used to aid in a crime scene reconstruction includes: Gunshot
residues, glass fragments and blood spatters
The presence of a cast-off pattern shows that there were more than ________ blow(s)
delivered: One
The sizes of the drops in a cast-off pattern are not related to the size of the point from which
they were propelled. (T/F) False
