The Department of Justice announced the charges last week, months after 18-year-old Anna Kepner died in November on the Carnival Cruise ship Horizon while the ship was en route to Miami.
Prosecutors alleged that the stepbrother «sexually assaulted and intentionally killed» Kepner. The Florida high school senior died from mechanical asphyxiation, officials said.
