"Darkroom"

Natalia's sister is kidnapped, along with several other women, by a man posing as a photographer. The CSIs are alerted to the crimes when an unidentified woman passes a bloody bill to a toll-booth collector with a cry for help written on it. Soon afterward, a woman is found dead on a jetty near the toll booth and photos of the missing women are discovered in a safe.
