Christopher Kepner, father of Anna Kepner, who died on a cruise, will now be required to appear in court on Dec. 5. No reason was given for why.

Anna Kepner's grandparents Barbara and Jeffrey were on the Caribbean cruise with her father, stepmother and siblings when she was found dead under a bed

Anna Kepner, the teen found mysteriously dead on a Carnival cruise ship earlier this month, and the stepbrother reportedly suspected in her death were like “two peas in a pod,” her grandma said Monday.

Anna Kepner’s younger stepbrother — a “suspect” in her killing — had a creepy obsession with the Florida cheerleader and was once caught climbing on top of her while she slept, according to the father of the slain 18-year-old’s ex-boyfriend.

In a petition filed in a child custody case, Thomas Hudson, the biological father of Anna's 16-year-old stepbrother said the teen is a "suspect in the death of the step child during the cruise," according to a court document obtained by PEOPLE.
