'Criminal Minds' says goodbye to another character

Farewell, Stephen Walker.

Criminal Minds is bidding farewell to Damon Gupton, who stepped in after the high-profile departure of Thomas Gibson last year to play Agent Stephen Walker. The actor announced his departure via Twitter this weekend.

Gupton’s exit comes as two of its most popular stars — Kirsten Vangsness and A.J. Cook — are looking for a boost in salary to reportedly equal what co-stars Joe Mantegna and Matthew Gray Gubler are now earning on the long-running CBS show. Both women have been on the show since it launched in 2005.

Criminal Minds ended with a cliffhanger last month with most of the team involved in a devastating car accident that was instigated by Mr. Scratch. Shemar Moore also briefly reprised his role as Derek Morgan.
