Kepner was aboard Carnival’s Horizon with her stepbrother and other family members on international waters en route to Miami when prosecutors said T.H. “allegedly sexually assaulted and intentionally killed Kepner.”
The Miami-Dade Medical Examiner’s Office determined Kepner’s cause of death to be mechanical asphyxiation, prosecutors said. A manner of death was not revealed.
In February, T.H. was initially charged as a juvenile; but, prosecutors said U.S. District Judge Beth Bloom ordered the case be transferred for adult prosecution.
