William Peterson Leaving CSI and Vegas!
Grissom gone?? According to a new report, this season’s 10th episode will be the last for William Peterson helming the CSI crew in Las Vegas, at least as a full-time series regular.
“Billy is leaving,” confirms the show’s executive producer, Carol Mendelsohn to the Ausiello Files at EW. “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.”
