Lauren Lee Smith will not be returning to the "CSI" set when the show debuts its 10th season this fall, TVGuide Magazine reports.

Smith played show regular Riley Adams, a character that show executive producer Naren Shankar says never really found her "footing" among the rest of the ensemble.

Jorja Fox, however, will return in at least five episodes of the upcoming season.

I wonder how her character is going to leave the show.

That's too bad. I still remember when she took over for Kellie Martin as Christy in the PAX TV movies.

I never saw her final episode. Was she killed off or what?
