A Florida teenager has been accused of murdering his stepsister, Anna Kepner, on a Carnival cruise ship. The teen, Timothy Hudson, has been ordered by a judge to be held in custody until his murder trial, following assessments of his psychopathy and alleged lack of remorse. Investigations revealed that Hudson attempted to destroy evidence related to the case. He was taken into custody by federal officials and faced additional charges, prompting the court to revoke his pretrial release. The details of the case continue to unfold, as prosecutors work to seal certain aspects of the evidence.
