Family speaks out after stepbrother emerges as suspect in death of Florida teen on cruise

Anna Kepner, 18, from Titusville, was found dead of asphyxiation under a bed on a Carnival cruise ship

The grandparents of a high school senior found dead on a cruise ship earlier in November say they fear they have lost two grandchildren after her stepbrother has emerged as a suspect in the case.

No matter what we find out, no matter what they tell us, it's not going to bring either one of these children back," Barbara Kepner, the grandmother of the late 18-year-old cheerleader Anna Kepner told ABC News on Monday.
