CSI: Crime Scene Investigation

William Petersen was originally reported to have renewed his contract for the show's ninth season, but the Associated Press reported on July 15, 2008, that Petersen was leaving the show as a regular following Season 9's tenth episode in order to pursue more stage acting opportunities. He will return for guest spots during the show's run, as needed. He will remain an Executive Producer of the show.

Warrick Brown's character will not return in Season 9, since actor Gary Dourdan and CBS could not come to terms on a contract. As a result, in the Season 8 finale, the undersheriff shoots Warrick in the neck and chest while he is sitting in his car, and then leaves him to die from his wounds. He dies in the opening moments with Gil Grissom holding him in the Season 9 premiere.

A few episodes later, in "Goodbye and Good Luck", Sara leaves the team following a difficult case. She did not say good bye to her fellow CSIs nor Grissom, for whom she only left a note stating that she had to go face the ghosts of her past, something that she couldn't do in Las Vegas. She returned for a guest appearance in the season 9 premiere for Warrick's death.
