(AP Photo/Rebecca Blackwell) MIAMI - A teenager charged with sexually assaulting and killing his 18-year-old stepsister on a Carnival Cruise ship surrendered Monday after a federal judge reversed his decision on pretrial release now that the teen is charged as an adult. The U.S. Attorney's Office in Miami confirmed that Timothy Hudson is in custody. U.S. Magistrate Judge Edwin Torres filed the order to revoke Hudson's pretrial release last Wednesday, but the order was sealed until Monday afternoon. The order stated that Hudson should surrender to U.S. Marshals at the federal courthouse in Tampa Monday morning. The judge had ruled in February that the 16-year-old could live with an uncle and be electronically monitored. But after the case was transferred to adult court in April, prosecutors wanted Hudson in custody. The judge ultimately agreed that the issue of Hudson's pretrial detention should be treated as if he was an adult, though Hudson will be held in an approved juvenile facility. The Government has established, by clear and convincing evidence, that no condition or combination of conditions of release will reasonably assure the safety of the community going forward, Torres wrote in his order. Hudson has pleaded not guilty to charges of first-degree murder and aggravated sexual abuse in the death of Anna Kepner. His federal public defenders have declined to comment on the charges. Minors are rarely prosecuted in federal court, and this case landed there because Kepner apparently died in international waters, outside any state's jurisdiction. Kepner had been traveling on the Carnival Horizon ship in November with her family, including Hudson. Before the ship was scheduled to return to Florida, her body was found concealed under a bed in a room she was sharing with Hudson and another teen, a criminal complaint said.
