A teenager accused of sexually assaulting and killing his 18-year-old stepsister on a Carnival Cruise ship surrenders to federal custody after a judge revokes his pretrial release. Multiple outlets report that Timothy Hudson, who had been out on pretrial release when he was charged as a juvenile, is taken into custody following the change to adult charges. According to coverage citing U.S. authorities, a U.S. magistrate judge (Edwin Torres) orders the revocation after Hudson is charged as an adult, and the order is sealed until it is unsealed on Monday. Reports say the judge’s order requires Hudson to surrender to U.S. marshals at the federal courthouse in Tampa. CBS News adds that once the case is treated as an adult matter, the judge rules he is no longer subject to juvenile-detention rules. One report also notes Hudson is held pending trial, with reference to being placed in an approved juvenile facility pending the legal process. The U.S. Attorney’s Office in Miami confirms Hudson is in custody.
