A teenager has been indicted on charges of murder and aggravated sexual abuse following the death of his stepsister aboard the Carnival Cruise Line’s “Horizon” in November 2025. The boy, identified as T.H. in court documents, will face trial as an adult in the U.S. District Court for the Southern District of Florida.

The indictment comes nearly five months after the tragic incident, which occurred while the cruise ship was returning to Miami following a week-long Caribbean journey. Anna Kepner, 18, was found deceased in their shared cabin, discovered lying beneath her bed shortly before noon on November 7, 2025. Allegations suggest that T.H. assaulted and subsequently killed Anna in the early hours of November 6 or 7.
Charges laid against T.H. stem from the circumstances surrounding Anna’s untimely death. The federal authorities have indicated that because the incident occurred in international waters, it falls under federal jurisdiction. According to the U.S. Attorney’s Office for the Southern District of Florida, the investigation began promptly upon the ship’s arrival back in Miami on November 8, where Federal Bureau of Investigation agents were waiting to interrogate Anna’s family members, including T.H.
Initial findings by the Miami-Dade Medical Examiner’s Office concluded that Anna’s cause of death was mechanical asphyxiation. Updates about the incident and the legal proceedings against T.H. have largely been sourced from family court records filed by T.H.’s parents. In an unsettling turn of events, T.H. made his first court appearance on February 6, during which he was released back into the custody of a family member—a decision that has drawn ire from Anna’s family.
Comments from Anna’s family reveal their profound grief and frustration over T.H.’s release. Shauntel Kepner, Anna’s mother, expressed that the reality of T.H. walking free is “deeply painful and disturbing.” She conveyed the family’s anguish, emphasising their struggle with the loss of Anna while the accused remains at large. Following the cruise incident, Shauntel reportedly severed all ties with her son, reflecting the emotional turmoil faced by the family.
As the legal proceedings unfold, T.H. faces severe penalties, potentially including life imprisonment, if convicted of the charges against him. His defence attorney has not yet provided statements to the press regarding the case.
U.S. Attorney Jason A. Reding Quiñones has conveyed condolences to the victim’s family, asserting that the prosecution will approach the case with diligence and professionalism. He noted the seriousness of the allegations and reiterated that T.H. remains innocent until proven guilty in court.
The indictment marks a significant development in a case that has garnered considerable media attention. Many are keenly observing the legal proceedings, eager to see how the case will unfold in the coming months. As the family seeks justice for Anna, the broader implications of the incident aboard the cruise ship continue to resonate, highlighting concerns surrounding safety and accountability in international waters.
This heart-wrenching case serves as a reminder of the dangerous realities that can lurk beneath the surface of seemingly idyllic holiday experiences. As the legal processes continues, the family of Anna Kepner is left to grapple with their heartbreak, hoping for justice and closure in the wake of their loss.
