Dallas Monroe is a singer, the wife of rapper Justin "Snake" Anderson, and the mother of their daughter Lexi. She was beaten and rendered unconscious while Snake was at a concert. Snake was suspected of abusing her, but he was cleared, and Dallas defended him.
It was eventually revealed that she was attacked by Andreas Harper, the son of a man Snake killed while he was still in the Projects. Andreas wanted revenge, as Snake's hush money to his mother Victoria wasn't enough. (SVU: "Diss")
