I read in the imdb that william petersen is going to come back he's leaving for a few episodes but that the one who might leave would be jorja fox
She is because..
She is going to be the one who dies.
The miniture crime scene killer left a package on Grissom's desk after he left.
If you notice as the camera is zooming in on the doll puzzle piece in the box , you see Sara's bedroom.
So maybe she will die in her room?
I have no idea.
I DON'T WANT SARA TO LEAVE. ]
