Answer
  • The same as
  • Less then
  • Greater than

Question 2

Question
The pointed end of a bloodstain always faces
Answer
  • Opposite its direction of travel
  • Toward the direction from which the force came
  • Its direction of travel
  • Toward the position of the blood source

Question 3

Question
A blood droplet deposited at an angle of impact of about 90º (directly vertical to the surface) will:
Answer
  • Show acute elongation
  • Feature a tail showing the directionality
  • Be elliptical in shape
  • Be approximately circular in shape

Question 4

Question
The most common type of bloodstain pattern found at a crime scene is:
Answer
  • Cast-off spatter
  • Void spatter
  • Impact spatter
  • Arterial spray

Question 5

Question
The velocity classification of an impact spatter pattern
Answer
  • Cannot illuminate the specific events that produced the pattern
  • Can determined the kind of action that produced the patter
  • Is never used for descriptive purpose
  • Can only be determined by a trained bloodstain pattern analyst

Question 6

Question
The intersection of straight lines through the long axis of several individual bloodstains in an impact spatter pattern illustrates the ______ of the pattern
Answer
  • Area of origin
  • Void patter
  • Area of convergence
  • Velocity classification

Question 7

Question
At the crime scene, the string method is used to find the ______ of an impact spatter pattern
Answer
  • Area of origin
  • Void pattern
  • Area of convergence
  • Velocity classification

Question 8

Question
The deposition of backward spatter produced by a gunshot wound is determined be:
Answer
  • The location of the injury
  • The size of the wound created
  • The distance between the victim and the muzzle
  • All of the above

Question 9

Question
If a murder victim's blood is found in the muzzle of a firearm:
Answer
  • No conclusion can be made
  • It can be concluded that the firearm is the murder weapon
  • It can be concluded that the firearm was present during the injury to the victim
  • It can be concluded that the owner of the firearm is the prepetrator

Question 10

Question
Which weapon would create cast-off patterns consisting of small droplets in a linear pattern?
Answer
  • Baseball bat
  • Knife
  • Wooden plank
  • All of the above

Question 11

Question
The pressure of the pumping of oxygenated blood out of an injury causes bright red-colored blood to spurt out and form a(n):
Answer
  • Void pattern
  • Expirated pattern
  • Arterial spray pattern
  • Both b and c

Question 12

Question
The removal of an object or surface that was located between the origin of blood and the target surface during the blodstain deposition leaves behind:
Answer
  • Expirated blood
  • A void
  • Blowback spatter
  • An undentifiable pattern

Question 13

Question
When an object with blood on it touches one that does not have blood on it, this produces a(n):
Answer
  • Flow
  • Indistinguishable pattern
  • Contact pattern
  • Trail pattern

Question 14

Question
Widely spaced bloody shoe prints with satellite spatter between the shoe prints were likely deposited by an individual who was:
Answer
  • Standing in place
  • Walking slowly
  • Running
  • Carrying a bloody weapon

Question 15

Question
The direction of a _______ may show movement of objects or bodies while the pattern was still forming or after the blood has dried
Answer
  • Flow pattern
  • Cast-off pattern
  • Bloodstain tail
  • Trail pattern

Question 16

Question
The approximate drying time of a pool of blood can be used to estimate timing of events at a crime scene and is dependent upon:
Answer
  • The clotting ability of the blood
  • The blood type of the blood
  • The environmental condition of the scene
  • The method of deposition

Question 17

Question
The skeletonized perimeter of a bloodstain can be used to interpret:
Answer
  • The kind of force that produced the bloodstain
  • The time that elapsed between deposition of the stain and alteration of the stain
  • The source of the bloodstain
  • Both b and c
