The death of 18-year-old Anna Marie Kepner aboard the Carnival Horizon cruise ship has taken a sharper turn as investigators now confirm that her teen stepbrother is under investigation as a suspect, according to reports.
The development comes as unverified, highly emotional claims from a man identifying himself as Kepner's uncle circulate widely on social media, accusing Anna's stepmother and stepbrother of responsibility for her death and claiming that Anna's father has refused to speak publicly about what happened.
