Update: At a hearing this afternoon, charges were dismissed against Aron Ralston in relation to his arrest Saturday night. The incident reportedly revolved around Vita Shannon, identified as Ralston's girlfriend. She's said to have hit him twice in the head, while he allegedly shoved her while leaving her apartment. Like Ralston, she was arrested on suspicion of assault and wrongs to minors (because their eight-week-old child was present). However, no charges were pursued against her, either, at the request of the city attorney. See Shannon's pic below, followed by earlier coverage.
