What Are These Strange Drops of Blood On Her Body?

The elevator's doors close
As the murderer sneaks in
Gorgeous girl, stabbed to death
A scalpel thrusting into her throat
Black girl stripped and tied up
Water slowly filling up the bathtub
Watching her slowly drowning
With her eyes wide open
Coated in black, rubber gloves on
Woman stabbed in the gut
In broad daylight
Bleeding to death in a crowded street
