Stepbrother charged in sexual assault and killing during family cruise, officials say

April 13, 2026

A 16-year-old male has been indicted as an adult for allegedly sexually assaulting and killing his 18-year-old stepsister, Anna Kepner, aboard a Carnival cruise ship traveling through international waters in November. Anna's body was discovered beneath a bed, concealed by blankets and life vests, with medical examiners determining she died from mechanical asphyxiation. The victim, a cheerleader planning to graduate high school and pursue a military career, was traveling with extended family members who described their blended family as close-knit and harmonious.

Who is affected

Anna Kepner (18-year-old victim, deceased)
The 16-year-old stepbrother (charged suspect)
Anna's father and stepmother
Anna's grandparents, Barbara and Jeffrey Kepner
Multiple other family members who were traveling on the cruise
Anna's cheerleading team and school community in Florida

What action is being taken

The U.S. Department of Justice is prosecuting the case
The stepbrother has been indicted as an adult on first-degree murder and aggravated sexual abuse charges
The case is proceeding through the federal court system

Why it matters

This case highlights the tragedy of family violence occurring in what should have been a safe, celebratory environment. The federal prosecution demonstrates how crimes committed in international waters fall under U.S. federal jurisdiction when involving American citizens on U.S.-based cruise ships. The decision to charge the 16-year-old as an adult rather than a juvenile reflects the severity of the alleged crimes and could result in a life sentence, making this a significant case regarding how the justice system handles serious violent crimes committed by minors.
