Snuff - S3.E8

Catherine called in by a pornographic-film developer to view graphic footage from a snuff movie in which a woman is brutally slain. But the clues are scant: The murderer isn't clearly seen, the cheap-looking hotel room could be almost anywhere and the film was sent to the developer anonymously. Outside of town, Grissom investigates another killing when a body, smothered with fire ants, is found stuffed inside a large toolbox. The initial findings indicate that the person died well over a year earlier.
