A regular on CSI since 2005, Liz Vassey will not be returning to the CBS hit.

According to a show insider, the series has chosen not to renew this actress' contract for another year, meaning viewers have seen the last of Wendy.

“The show is going in a different creative direction in its 11th season,” this source told Entertainment Weekly.
