Camille Peterson is the wife of Senator Bryce Peterson, as well as the mistress of Dustin Henry and the killer of his sister, Brenna Lane. Camille would have operations and treatments to look younger because she didn't love her marriage, and Dustin, the flower deliveryman, was attracted to older women after a neighbor raped him when he was 14. Despite Camille's insecurities and Dustin's trauma and instability, the two began an affair. When Brenna found out and tried to personally inform Bryce, Camille confronted Brenna at her roommate's apartment and killed her with an exercize weight.
Dustin was originally suspected and arrested, but office manager Andrea Wheaton, who initially framed him with evidence from the cleanup, then said she was the mistress to still cover for Camille. However, Camille bribed Dustin with a wine account, which she herself used for her de-aging treatments, the details of them revealing she was the mystery lover and the killer. The Petersons were brought to confront Dustin, and after enough pushing on the truth of Dustin's affair, Camille confessed in full. Bryce was horrified, so she hit him and told him she felt more loved by Dustin then she ever would by Bryce. Camille also harasses Dustin, stroking his leg while telling him how she felt around him.
Camille took a plea to manslaughter one and was sentenced to twelve years in prison. (L&O: "Crashers")
