Blood Spatter Review

A blood stain pattern caused by a gunshot is?

• high velocity spatter

• passive spatter

• low velocity spatter

• medium velocity spatter

Blood deposited from direct contact between two surfaces, at least one of which is bloody?

• smear

• passive

• pool

• trail

Blood stain patterns resulting damage to a large blood vessel and the pumping action of the heart?

• passive

• splash

• arterial gush

• pool

The pointed or elongated stains that radiate from the central area of a bloodstain when blood overcomes its natural cohesion forces?

• tails

• spikes

• satellites

• parent drop

How can you differentiate between high and low velocity spatter?

• low velocity has larger drops

• high velocity has elongated tails

• low velocity has perfect circle like drops

• high velocity has many satellites

Explain how the surface that is hit by the blood can affect the type of spatter that is produced.

• rough surface more spines

• smooth surface smooth circle

• porous surface absorbs the blood

• all of the above

What direction is this blood moving toward?

• top

• bottom

• left

• right

Using string/lines and see where the lines cross to figure out location of blood, they place where they intersect is called:

• area of convergence

• point of origin

• blood comes from here spot

• source location

As blood drops from increasing heights, what happens to the size of the blood stain?

• gets larger

• gets smaller

• stays the same size

• doubles in size

Which test(s) would be used to determine if blood is present at a crime scene?

• DNA test

• antibody reaction test

• luminol

• leucomalachite
