TVGuide.com reports that The Shield star Kenny Johnson has been cast as Greg Taybeck, Lisbon’s former high school boyfriend and fiancé who becomes involved in one of her investigations.

The show’s creator and executive producer, Bruno Heller, told TVGuide.com: “I think it takes her longer to get to the bottom of the case because it’s hard for her to see the thing clearly. But it’s her understanding of him and his character that helps solve the case.”
