'CSI' casts 'Faking It' star Katie Stevens for two-hour send-off

Faking It‘s Katie Stevens has landed a guest-starring role in CSI’s two-hour swan song, EW has learned.

Stevens will play Catherine Willows’ (Marg Helgenberger) daughter, Lindsey Willows. Now in her early 20s, Lindsey is a CSI level 1 experiencing her first day on the job. Lindsey is described as an over-caffeinated, younger and bubbly version of her mom, minus a youthful mistake or two, who is on her way to a promising career. Lindsey actually nails down a key piece of evidence that moves the case forward.

If you’re a diehard CSI fan, you may recall that this is the third Lindsey Willows we’ve seen on the series. Madison McReynolds and Kay Panabaker both previously inhabited the role in the character’s younger years.

Stevens joins a long list of talent involved with CSI’s send-off, which includes Helgenberger, William Petersen, Ted Danson, Jorja Fox, Jon Wellner, David Berman, Paul Guilfoyle, Wallace Langham, Elizabeth Harnois, Robert David Hall, Eric Szmanda and Melinda Clarke. As EW previously reported, Elisabeth Shue will not return for the show’s series finale, which is being written by Anthony Zuiker.

CSI’s two-hour series-ender will air Sunday, Sept. 27 on CBS.
