What blood spatter pattern is seen in the picture?
Transfer/Contact
Passive
Latent
Saturation
Which letter best shows where the area of convergence would be?
A
B
C
D
When crime scene investigations trace all the angles back to one location, they refer to this as..
the area of convergance
the origin story
diameter of the blood drops
What is the relationship between height & spatter diameter?
There is no relationship
As height increases, spatter diameter decreases
As height increases, spatter diameter increases
It depends on the blood
Blood dripping off a weapon would be considered
Passive blood spatter
Projected blood spatter
Transfer blood

As blood drops from increasing heights, what happens to the size of the blood stain?
Gets larger.
Gets smaller.
Stays the same size.
Blood pumping from a severed artery would leave

This blood evidence would be considered..
passive
projected
drip
