A federal grand jury has indicted a 16-year-old boy as an adult for the sexual assault and murder of his 18-year-old stepsister aboard a cruise ship in international waters, marking a tragic end to what should have been a family vacation.
The Charges and Investigation
The teenager, identified in court records as T.H., faces first-degree murder and sexual abuse charges in the death of Anna Kepner. The incident occurred on November 6 or 7 aboard the Carnival Horizon cruise ship while the family vacationed together. Kepner’s body was discovered under a bed in her cabin by cleaning staff the following day. After the ship docked in Miami, the Miami-Dade Medical Examiner determined she died by mechanical asphyxiation.
U.S. Attorney Jason A. Reding Quiñones emphasized that while serious charges have been filed, the defendant remains presumed innocent until proven guilty. The case initially proceeded under juvenile court seal in February before Judge Beth Bloom transferred it for adult prosecution, making court documents public. If convicted, T.H. faces a maximum sentence of life in prison.
A Promising Life Cut Short
Anna Kepner was an honors student at Temple Christian School in Titusville, Florida, with ambitious plans for her future. Family members described her as pure energy—bubbly, funny, and outgoing. She had already earned her boater’s license before obtaining a driver’s license and planned to join the U.S. Navy after graduating high school. Her long-term goal was becoming a K9 officer. An accomplished gymnast, Kepner actively participated on her school’s cheerleading team.
Aftermath and Legal Proceedings
Following the incident, T.H. was hospitalized before being placed with maternal relatives near Hernando County. His name surfaced as a suspect during custody hearings involving his parents. The community mourned Kepner’s death with hundreds attending her celebration of life service on November 20. In the days following her death, loved ones transformed her car into a memorial site with flowers, balloons, and heartfelt messages. The federal prosecution reflects the serious nature of crimes committed in international waters, where U.S. law applies to American citizens aboard vessels.
