A federal judge has allowed a teenager charged with sexually assaulting and killing his 18-year-old stepsister on a Carnival Cruise ship to remain free for now. The judge is considering arguments following Wednesday's hearing in Miami. Timothy Hudson, initially charged as a juvenile, was allowed to live with an uncle and be electronically monitored. After the case moved to adult court, prosecutors wanted the 16-year-old in custody. The judge ended Wednesday's hearing without a final decision, saying he wants to talk to the U.S. Marshals Service about detaining Hudson closer to his family. Hudson has pleaded not guilty to first-degree murder and aggravated sexual abuse.
