Taylor matulin played the DotW ("death of the week") in "link" which was episode 16 of season 9. Considering her character was, um, dead, I highly doubt she will be returning to the show.
Several celebrities and telebisyon stars have had spots on CSI, including favorites like Dakota Fanning, Marcia Cross, Evan Rachel Wood, Jeffrey Tambor, Alan Tudyk, and Charisma Carpenter. But they're always either suspects, victims, witnesses or killers. Not recurring roles.
