William Petersen Leaving CSI

ON

Entertainment Weekly is reporting that this upcoming season’s 10th episode of “CSI” will be the last for William Petersen as a full-time series regular.

“Billy is leaving,” confirmed executive producer, Carol Mendelsohn. “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.”

“I’m in a great place in terms of knowing that I’ll be more free to make choices. And I’m responsible enough to not do it in a way that would hurt [the show],” added Petersen. “I want it to work for the writers, I want it to work for the cast, and, most importantly, I want it to work for the audience. I don’t want them to abandon the show.”
