Draw what a drop of blood dropped from a 90 degree angle would be expected to look like.

Blood at a crime scene can also contain bits of tissue and bone-- This usually indicates a ________ _________ pattern.

• High-velocity

• knife

• Medium-velocity

Transfers can be left by (choose all that apply):

• weapons

What can overlapping blood drops/patterns be useful in determining?
