Lucille is Marv's parole officer, a beautiful lesbian. Marv thinks that her gorgeous body is wasted. Lucille gives Marv medicine for his mental condition, provided by her lover who is a psychiatrist. Lucille is taken captive by Kevin, who forces her to watch while he eats her hand, which he has cut off while she was unconscious. Lucille is at first hysterical when Marv joins her in captivity, but after a crying fit, she calms down and is able to escape with him. Lucille, however, doesn't realize the depth of corruption in Sin City. When the police land in helicopters, she hits Marv on the head with a rock and goes to the officers, trying to turn Marv in peacefully. Instead, the corrupt police shoot her dead for her knowledge of Kevin's activities and her involvement with Marv. When Marv is arrested, he is forced to confess to killing Lucille.
