That really messed Maddie up. You always kind of think of rapists as deranged looking wild men. Or so he appeared to be. Appearances can be deceiving. I've been doing some reading about this.
Rapists come in many forms.
And there are also different types of rapists that rape for different reasons. From what I could gather about this guy, I think he's in the Sadistic category. I know the rapes had gotten progressively more violent, and the last one ended in murder. This kind of rapist is the most dangerous and the most cunning. The sadistic rapist is usually of a higher intelligence and is hard to catch, usually because his victims die.
