CSI: Las Vegas - Casting News - Liz Vassey Leaves

CSI will be down one lab rat when the show returns next fall.

A CBS rep declined to comment, but a source close to the long-running procedural confirms that Liz Vassey’s (Wendy) contract option has not been picked up.

“The show is going in a different creative direction in its 11th season,” says the insider.
News of Vassey’s departure comes as several of her co-stars are negotiating new contracts. Might this be a precursor to a larger cast shake-up? That’s a rhetorical query. I honestly don’t know if anyone else is leaving. But an investigation has been launched and I’ll hopefully have answers soon.
