Jonathan Togo is set to join the investigative team on CBS’ Monday night hit “CSI: Miami.” The young actor will make his first appearance on the show’s Oct. 11 episode.

Togo will play Ryan Wolfe, an office hand-picked for the team by David Caruso’s Horatio Caine. Wolfe is working toward his masters degree in genetics, which is bound to be helpful in the line of duty.

Familiar from his work in the Oscar-winning “Mystic River,” Togo’s list of television guest starring roles includes stints on “Law & Order,” “Ed” and “The Jury.” He also was a regular on UPN’s “Special Unit 2.”

“When you have a cast led by David Caruso, the bar is already set really high,” says executive producer Ann Donahue. “Jonathan came in and we knew immediately that he would fit in as one of our CSIs. We are thrilled to welcome him to the team.”

Togo will serve as a replacement for the member of the CSI team expected to die in the line of duty during the season’s first episode. Rory Cochrane’s Tim Speedle is considered the most likely possibility for departure, though nobody this side of David Caruso should be considered 100 percent safe.
