An 18-year-old Florida high-school senior, Anna Kepner, has been found dead aboard a six-day Caribbean cruise, and federal investigators are now examining one of her teenage step-siblings as a possible suspect in her death.
According to legal filings disclosed in a Florida family-court case, the 16-year-old stepsibling — identified only by initials “T.H.” in the documents — is “now a suspect in the death of the step-child during the cruise,” the boy’s father wrote. The filing states the boy is under investigation by the Federal Bureau of Investigation (FBI) in connection with Kepner’s death.
The cruise ship in question is the Carnival Horizon, which returned to Port Miami on 8 November 2025 after the discovery of Kepner’s body. The exact cause and manner of her death remain undetermined; the Miami-Dade County Medical Examiner’s office provided the time of death as 11:17 a.m. on 7 November, but has not released details of how she died.
Kepner, a senior at Temple Christian School in Titusville, Florida, was described by friends and family in her obituary as “pure energy: bubbly, funny, outgoing, and completely herself.” She had aspirations of joining the United States Navy and then working as a K-9 police officer, according to reporting. She had attended several high schools, was a member of the cheer squad at Titusville High School, and more recently enrolled at Temple Christian.
On board the cruise, Kepner was sailing with her father, her step-mother Shauntel Hudson, and at least two minors, including her 14-year-old brother and the 16-year-old step-brother. According to one source of the investigation, the younger brother returned to the stateroom the night of 6 November and later went to sleep, unaware of Kepner’s presence underneath the bed.
According to press reports citing court filings, Kepner’s body was discovered by a cabin steward or housekeeper cleaning the room. The body was described in some reports as being wrapped in a blanket and hidden under a bed, surrounded by life jackets. The voyage had been a standard Miami-to-Caribbean trip, and the ship returned to Miami when Kepner did not show up for breakfast and was later reported missing.
Court documents filed in an unrelated custody dispute note that “a criminal case may be initiated against one of the minor children of this instant action,” referring to the stepson, and that the step-mother has requested a delay in her scheduled hearing because any testimony she gives could be “prejudicial to her or her adolescent child in this pending criminal investigation.”
Although no formal charges have been filed publicly, the documents mark the first time a specific family member has been described as a suspect in the case. Earlier, the FBI and cruise line stated only that they were cooperating. The cruise operator, Carnival Cruise Line, confirmed the ship was assisting the Miami FBI office in the investigation.
Kepner’s mother, Heather Kepner, told FOX 35 she discovered her daughter’s death via Google search and described her child as someone who “never really complained” and was “just always happy.” According to her obituary, in lieu of a traditional black-attire funeral the family requested guests wear colorful clothes—especially blue, her favorite colour—to celebrate her vibrant personality.
Beyond the missing details of how Kepner died, additional legal and family-dynamics issues are emerging. Court filings reveal alleged longstanding tensions in the blended household. In one motion, the step-mother accused her ex-husband of domestic and physical abuse directed at the two younger children, including the 16-year-old now under investigation. In another filing, the father of the 16-year-old claimed the boy’s future was “in jeopardy” because of decisions made by the step-mother.
At this stage, investigators are reported to be examining the Carnival Horizon’s security footage, interior card-swipe records, and passenger movements from the cabin in question, including the timeline of the night Kepner went missing. Among points of interest are the fact that Kepner told her family she was feeling sick during dinner the evening before she died and returned to her cabin alone earlier than the rest of the group.
The FBI has not released a statement commenting on any suspect, noting that the agency “does not provide operational updates about ongoing investigations.” The Miami-Dade Medical Examiner’s office has likewise not released a detailed autopsy report, and it remains unclear when or if one will be publicly released. Kepner’s family held a memorial service in Titusville on 20 November 2025, during which mourners wore colours in her honour and laid flowers at her school rather than inside a church.
As the investigation continues, the focus on the 16-year-old stepsibling represents a crucial shift in the case. The context of a vacation-cruise setting, occurring in international waters, gave the FBI jurisdiction, and the eventual return of the vessel to Miami keyed the federal inquiry. The case highlights both the complexity of jurisdiction in maritime deaths and the sensitivity of investigations involving minors and blended families.
At present, the key questions remain: how did Anna Kepner die, what occurred in her stateroom the night before her body was found, why was her body hidden beneath a bed, and what, if any, role did the 16-year-old stepsibling play in the events leading to her death. Until official statements or charges are issued, the publicly available information rests primarily on court filings and press reports.
