When 18-year-old Anna Kepner boarded the Carnival Horizon with members of her blended family in November 2025, it was supposed to be a vacation.

She never came home.

Kepner, a Florida high-school senior and cheerleader, was found dead aboard the cruise ship as it traveled through international waters toward Miami. Her death was later ruled a homicide, with the Miami-Dade Medical Examiner determining that she died from mechanical asphyxiation.

Federal prosecutors eventually accused her 16-year-old stepbrother, Timothy Hudson, of sexually assaulting and intentionally killing her aboard the ship. Hudson has pleaded not guilty and is being prosecuted as an adult on charges that include first-degree murder and aggravated sexual abuse.

He has not been convicted, and the allegations against him remain to be tested in court.

But now, as the case approaches trial, another complication has emerged.

Hudson’s lawyers say the same family relationships that surrounded the alleged crime are making it more difficult to prepare his defense.

In an August court filing, the defense cited what it called a “unique — and very unfortunate — family dynamic” and said attorneys had been unable to obtain the level of access they needed to certain family members.

The problem was serious enough that Hudson’s September trial was postponed until November.

A Death at Sea Becomes a Federal Murder Case

According to federal prosecutors, Hudson and Kepner were traveling aboard Carnival Cruise Line’s Horizon with other relatives on or about Nov. 6 and Nov. 7, 2025.

The ship was in international waters and returning toward Miami when prosecutors allege Hudson sexually assaulted Kepner and intentionally killed her.

Kepner’s body was discovered aboard the vessel on Nov. 7.

The unusual location immediately placed the case within federal jurisdiction and drew substantial attention. A killing aboard a cruise ship already presents investigative challenges that differ from an ordinary homicide on land: the alleged crime scene is moving, passengers may disperse once the ship reaches port, and federal authorities may become involved depending on the vessel, destination and location of the alleged offense.

The case became even more extraordinary when investigators focused on someone who had been traveling with Kepner as part of the same family group.

Hudson was initially handled as a juvenile. But in April, the U.S. Attorney’s Office for the Southern District of Florida announced that a federal grand jury had indicted him as an adult.

He later pleaded not guilty.

By June, a judge had ordered that Hudson remain detained pending trial rather than continue under the earlier arrangement that had allowed him to stay with a relative under restrictions.

A Trial That Keeps Moving

Hudson’s trial was originally expected considerably earlier.

At one point it had been scheduled for June, and it was subsequently placed on the calendar for Sept. 8.

Then his lawyers asked for more time.

Their request was not based simply on the volume of discovery or the complexity of forensic evidence.

They pointed specifically to Hudson’s age and family circumstances.

Because Hudson was 16 when Kepner died, the defense said additional investigation was necessary into his juvenile background and into factors that could become critical if he is convicted and later faces a possible life sentence.

The defense described the situation as involving a “unique — and very unfortunate — family dynamic” resulting from the allegations. Attorneys said they did “not have the type of access to certain family members” that would allow them to complete their investigation as efficiently as necessary.

Prosecutors did not oppose the request.

U.S. District Judge Beth Bloom granted the continuance, moving the federal trial to the two-week period beginning Nov. 2, 2026. The deadline for a potential plea agreement was also moved to Oct. 23.

Why Family Interviews Could Matter Beyond Guilt or Innocence

The defense’s difficulty reaching relatives may affect more than just the trial itself.

Because Hudson was a juvenile at the time of the alleged offenses, his lawyers are preparing for the possibility of what is known as a Miller hearing.

Such a proceeding stems from U.S. Supreme Court precedent requiring courts to consider the distinctive circumstances of juvenile defendants before imposing certain severe sentences, including life without parole.

That means defense attorneys may need detailed information about Hudson’s upbringing, home environment, emotional development, family relationships and other mitigating factors.

People reported that the relatives the defense is seeking to interview could therefore be important both to investigating the criminal allegations and to preparing for a possible sentencing phase.

That creates an unusual situation.

Some members of the blended family may have relationships with both the alleged victim and the defendant.

The same people coping with Kepner’s death could also possess information Hudson’s lawyers consider necessary to defend him against the accusation that he killed her.

The defense has not publicly identified every relative it has struggled to access.

Separate Family Disputes Add Another Layer

The family tensions have also surfaced outside the federal criminal case.

Court records reported in September show that Hudson’s biological parents, Shauntel Hudson and Thomas Hudson, have been engaged in a separate dispute involving child support and their relationships with their children.

Shauntel Hudson — Timothy’s mother and Anna Kepner’s stepmother — has accused her former husband of failing to make all required support payments and has asked a Florida court to reassess the financial arrangement.

Thomas Hudson has disputed portions of her account, including her characterization of his relationship with the children. A judge had not yet resolved that dispute as of early September.

The child-support case is separate from the federal prosecution and does not establish anything about Hudson’s guilt or innocence.

But its existence provides additional public evidence of the complicated family environment his defense referenced when requesting more preparation time.

Evidence Still Being Prepared

The postponement does not mean the prosecution has stopped moving forward.

Earlier in August, court records showed prosecutors had obtained Kepner’s Snapchat data and turned the material over to Hudson’s attorneys as part of discovery.

Digital communications could become important in reconstructing the hours before Kepner’s death, her interactions with people aboard the ship and the relationships within the group.

Exactly how much of that material prosecutors intend to use at trial remains unclear.

Likewise, many important questions about the government’s complete evidence have not yet been tested before a jury.

Federal prosecutors have publicly alleged that Hudson sexually assaulted and intentionally killed Kepner.

The defense is entitled to challenge the government’s forensic evidence, witness accounts, timeline and interpretation of events.

A Case About One Family, Now Divided Across a Courtroom

Kepner was remembered as a cheerful teenager with plans for her future.

She was a high-school senior in Titusville, Florida, and had participated in cheerleading and gymnastics. Her mother described her as someone who enjoyed making people laugh and loved the water.

Instead of preparing for graduation, her family is now preparing for a federal murder trial.

And the unusual structure of that family has become part of the legal story.

The prosecution alleges that one teenager in the family killed another while they were all aboard the same cruise ship.

Now, Hudson’s attorneys say they need cooperation from relatives connected to that same family in order to investigate the case properly and prepare for what could follow if he is convicted.

The delay does not change the charges.

It does not establish Hudson’s guilt.

And it does not indicate that any relative has done anything improper by being difficult or unavailable to defense lawyers.

What it does show is how deeply the alleged crime has fractured the group of people surrounding both Anna Kepner and the teenager accused of killing her.

For now, the trial is scheduled to begin Nov. 2.

When it does, jurors will be asked to determine what happened aboard the Carnival Horizon in November 2025.

But before that trial can begin, Hudson’s lawyers say they are still trying to understand another part of the story:

the family that was on the ship with them.
