Stepbrother Indicted as Adult in Cruise Ship Murder of Anna Kepner
Key Aspects:
The 16-year-old stepbrother of Anna Kepner has been charged with murder and aggravated sexual abuse.
18-year-old Kepner was killed onboard Carnival Horizon in early November 2025.
Kepner’s stepbrother will face a maximum penalty of life in prison if convicted.
Five months after the tragic death of Anna Kepner during a family vacation aboard Carnival Horizon in November 2025, official charges have been filed against the young woman’s 16-year-old stepbrother.
The US Department of Justice has identified the young man simply by the initials T.H., but he has been indicted as an adult. The charges include murder in the first degree and aggravated sexual abuse. Initially, T.H. was to have been charged as a juvenile but the case was transferred for adult prosecution.
“Our hearts go out to the victim’s family during this unimaginable loss,” said US Attorney Jason A. Reding Quiñones for the Southern District of Florida.
“A federal grand jury has returned an indictment charging serious offenses that allegedly occurred aboard a vessel in international waters. We will present the evidence in court and pursue this case with professionalism and care. As in every case, the defendant is presumed innocent unless and until proven guilty beyond a reasonable doubt.”
Attorneys and court officials make the determination for juvenile versus adult prosecution based on the crime’s severity and individual circumstances, including the histories of those involved as well as psychological evaluations and other information.
If T.H. is convicted, he will face a maximum penalty of life in prison. Assistant US Attorney Alejandra L. López is prosecuting the case.
Cruise Hive has followed the case closely, from the time Kepner was first discovered deceased onboard Carnival Horizon. Carnival Cruise Line has not commented publicly on the case, as is standard for any ongoing legal proceedings.
To be clear, no crew members were involved in the incident and the cruise line is not part of the lawsuit.
The Death of Anna Kepner
Anna Kepner was found dead in her cruise ship stateroom on November 8, 2025. She had embarked Carnival Horizon in Miami on November 2 for a 6-night Western Caribbean sailing to Grand Cayman and Cozumel with her family.
Kepner was sharing a stateroom on Deck 8 with the 16-year-old T.H. and another 14-year-old stepbrother. She was found wrapped in a sheet beneath the bed and hidden by lifejackets after failing to arrive for breakfast on Saturday, November 8, the last day of the cruise.

First reports of her death did not identify Kepner as the victim, but the news quickly broke about the tragedy. Because of the suspicious nature of the death, the Federal Bureau of Investigation (FBI) was notified and took charge of the investigation.
The cause of death was determined to be “mechanical asphyxiation” from a bar hold, a type of brutal strangulation by leaning a forearm across the victim’s throat. The cruise ship was in international waters at the time of Kepner’s death.
Anna was a senior at Temple Christian School in Titusville, Florida. She was set to graduate in May 2026 and had ambitions to join the military.
Tremendous drama has surrounded the investigation into her death, particularly when text messages sent between Kepner’s stepmother and her ex-husband, T.H.’s father, seemed to indicate a type of damage control mindset for the parents who already suspected their son might be charged.
Kepner was beloved in her community and had hundreds of tributes from classmates, teachers, friends, co-workers, and other community members.
All authorities involved in this case have continued to stress that T.H. is innocent until proven guilty beyond a reasonable doubt in a court of law. At this time, no trial date has yet been announced.
