Anna Kepner's 18-year-old body was found wrapped in a blanket under a bed on a cruise ship in November 2025, with few clues as to what happened to her. Now, her teenage stepbrother has reportedly been arrested and charged, according to a close family member. On Friday, February 6, the teenage boy, 16, appeared in court in Miami alongside public defenders and prosecutors. Anna's father, Chris Kepner, told ABC News that he's since been released to the custody of a guardian.
