[Warning: Potentially Triggering Content] A shocking discovery has been made in the tragic case of Anna Kepner. Last November, the 18-year-old high school senior boarded a Carnival Horizon cruise with her blended family, including father Christopher Kepner, stepmother Shauntel Hudson, grandparents, and two younger stepsiblings, including her 16-year-old stepbrother. The vacation quickly spiraled into a nightmare, though, when Anna was found dead, wrapped in blankets and life vests, and shoved underneath her bed in the room she shared with her stepsiblings.
