Titusville Teen Charged as Adult in Killing of Stepsister on Cruise Ship

MIAMI - A 16-year-old has been indicted as an adult by a federal grand jury on charges of murder and aggravated sexual abuse in the killing of his stepsister.

According to court records, T.H., 16, of Titusville, was traveling aboard Carnival Cruise Line's Horizon with Anna Kepner and other family members on or about Nov. 6-7, 2025. During that time, while the ship was in international waters en route to Miami, T.H. allegedly sexually assaulted and intentionally killed Kepner. The Miami-Dade Medical Examiner's Office later determined the cause of death to be mechanical asphyxiation.

"Our hearts go out to the victim's family during this unimaginable loss," said U.S. 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."

T.H. was initially charged as a juvenile by information on Feb. 2. The case remained sealed until U.S. District Judge Beth Bloom ordered it transferred for adult prosecution.

T.H. is charged with murder in the first degree and aggravated sexual abuse. If convicted, Defendant faces a maximum penalty of life in prison.

U.S. Attorney Reding Quiñones and Special Agent in Charge Brett D. Skiles of the FBI, Miami Field Office, made the announcement.

FBI Miami is investigating the case.

Assistant U.S. Attorney Alejandra L. López is prosecuting the case.

An indictment is merely an allegation. All defendants are presumed innocent until proven guilty beyond a reasonable doubt in a court of law.
