An arrest comes three months after Anna Kepner dies on a cruise with her family. The cheerleader's 16-year-old stepbrother arrested and charged in her death, ruled a homicide by mechanical asphyxiation.

Anna Kepner, 18, had begun her senior year at Temple Christian School, and was reportedly excited about her future, painting her school parking spot to match her favorite movie, "Clueless. "   Anna plans included joining the military after high school.  

Anna was found dead aboard the Carnival Horizon cruise ship during a recent western Caribbean voyage that ended in Miami. Her body stuffed under a bunk in the room she shared with her stepbrother.   He has now been charged with homicide.
