New details from Anna Kepner's death certificate

Anna Kepner's father was subpoenaed in the family court custody case this morning. In addition, a copy of Anna Kepner's death certificate obtained by FOX News reveals Anna's body was cremated after her death on board the Carnival Horizon cruise ship. The publicly available document does not include her cause or manner of death. The Miami-Dade Medical Examiner's Office and FBI refused to comment, citing the ongoing investigation into Anna Kepner's death. The FBI previously listed Anna's teen stepbrother as a suspect in a potential murder case surrounding Anna Kepner's death.
