@cbsnews: A federal judge allowed the teenager charged with sexually assaulting and killing his 18-year-old stepsister, Anna Kepner, on a Carnival Cruise ship to remain free for now as the judge considers arguments following a hearing in Miami. Timothy Hudson was initially arrested and charged as a juvenile and allowed to live with a relative. Now that the case has been transferred to adult court, prosecutors want Hudson to remain in custody until the case concludes. The judge ended Wednesday morning's hearing without making a final decision. Hudson has pleaded not guilty to charges of first-degree murder and aggravated sexual abuse.
