Look for THE YOUNG & THE RESTLESS' Chris McKenna (Mark) in tonight's episode of CRIMINAL MINDS, airing at 9:00 p.m. ET on CBS. In the episode titled "Rock Creek Park," McKenna plays up-and-coming congressman Benjamin Troy, whose wife disappears mysteriously. When the BAU investigates his political enemies, will the congressman remain a victim or turn into a suspect? Academy Award-nominated actress Tess Harper plays his mother, Sophie, and of course, Y&R alum Shemar Moore (ex-Malcolm) stars in the primetime series.
