Producers have confirmed that William Petersen will be leaving ‘CSI: Crime Scene Investigation’ by the tenth episode of the upcoming season.
Petersen, who plays Gil Grissom, has agreed to return for guest appearances and will remain a executive producer but his run as an original cast member will end by midseason. Executive producers Carol Mendelsohn and Naren Shankar say the decision to leave was Petersen’s: “Billy is leaving… But he will remain throughout the run of the series an executive producer. And he will, whenever CBS asks, come back. I don’t think you’ve seen the last of Gil Grissom.”
