The serial killer nicknamed the ‘Miniature killer’ is finally revealed to be CSI lab cleaner Natalie Davis, and she has targeted Sara as her next victim. As Grissom races to rescue her, the season ends on a tense cliff-hanger as Sara is stuck in an upturned car in the Nevada desert.

It is also a memorable episode because it is the first time that Grissom openly admits that he loves Sara, and shocks the rest of the CSI team with his revelation.
