Exclusive: CSI Casts Dylan Walsh, Sarah Joy Brown in Killer Storyline

CSI Season 13 CastUnforgettable lawman Dylan Walsh is keeping busy between seasons by seeing how “the other half” lives, playing a serial killer on CBS’ CSI, TVLine has learned exclusively.

Joining Walsh in the episode — the tone of which, I hear, is “dark as the darkest night” — is General Hospital alum Sarah Joy Brown.

The set-up for this, Season 13’s eighth episode: The discovery of a mass grave in the Nevada desert suggests the work of Seattle serial killer Tom Cooley, a longtime nemesis of Elisabeth Shue’s CSI Julie Finlay. While it’s not clear if Walsh’s character and Cooley are one and the same, Brown is guest-starring as Karen, the wife of a Seattle cop who is questioned about her relationship with Tom, whose best friend she dated in high school.

Karen’s recollection of those teenage days will cue up flashbacks featuring teenage versions of Walsh and Brown.

Walsh’s previous TV credits include the aforementioned Unforgettable, which returns for Season 2 in Summer 2013, and of course Nip/Tuck. Brown, in addition to her daytime TV roles (including most recently Days of Our Lives), has guested on series such as Castle, The Closer, Cold Case and Without a Trace.
