Tyler James Williams, who recurs on The Walking Dead, is set to co-star opposite Gary Sinise in CBS’ Criminal Minds planted spinoff. The proposed spinoff will air as an episode of the mothership series written by Criminal Minds executive producer/showrunner Erica Messer.

Like Criminal Minds, the spinoff focuses on a division of the FBI. It follows agents helping American citizens who find themselves in trouble abroad. Sinise plays their boss, Jack Garrett. Williams will play the sweet and incredibly smart Monty. As the team’s tech analyst, Monty stays at home while the team works abroad. His attention to detail and kind manner are invaluable as he liaises with the families of those in trouble and uses his tech savvy to help the team fill in the holes as they search for a killer far from home.
