Anna Marie Kepner, eighteen, a senior at Temple Christian School in Titusville, Florida, was found dead on November 7, 2025, inside a cabin she shared with her stepbrother and half-brother aboard the Carnival Horizon cruise ship during a family vacation. Her body was reportedly concealed under a bed, wrapped in a blanket, and covered with life jackets. The Miami-Dade Medical Examiner determined the cause of death to be mechanical asphyxiation.
Her sixteen-year-old stepbrother has been indicted by a federal grand jury on charges of first-degree murder and aggravated sexual abuse. He has entered a plea of not guilty. The case falls under federal jurisdiction because the death occurred in international waters, with the FBI leading the investigation. If convicted, the accused faces a maximum sentence of life in federal prison. The death penalty is not available due to the defendant's age.
The accused was initially charged as a juvenile in February 2026. The case was transferred to adult court on April 10, with defense counsel not objecting to the transfer. He was released to the custody of a relative under GPS monitoring, with conditions including a prohibition on being unsupervised with anyone under eighteen. The U.S. Attorney's Office has since moved to revoke pretrial release, arguing the defendant poses a danger.
Defense attorney and former felony prosecutor Eric Faddis provides analysis of the evidentiary posture and procedural trajectory of this case. He examines the reported surveillance evidence showing only the accused entering and exiting the stateroom during the relevant window, the defense decision not to contest the transfer to adult prosecution, and the potential scope of a defense built around the accused's documented medication history — specifically, testimony that the accused missed prescribed insomnia medication for two consecutive nights aboard the ship. Faddis also addresses the unusual family dynamics: the victim's father, who is the accused's stepfather, has publicly stated that justice must be served.
