Anna Kepner Timeline: Final Days of Florida Teen Before Cruise Ship Murder By Chris Spargo

“Anna was pure energy: bubbly, funny, outgoing, and completely herself. ”

That is how Anna Kepner is remembered in her obituary.

The 18-year-old high school student lost her life while traveling with her family on the Carnival Horizon cruise ship in early November.

Her death was later declared a homicide. While there have been no arrests made at this time, court papers filed in the custody proceedings between Anna’s stepmother Shauntel Hudson and her ex-husband suggest that Anna’s 16-year-old stepbrother is under criminal investigation,

When asked about his estranged stepson’s possible involvement in his daughter’s murder, Christopher Kepner previously told PEOPLE: “I cannot say that he is responsible but I can’t decline. He was the only one that was in the room and the FBI has an ongoing investigation in which they will have to provide the evidence to say that he did do it or did not do this.”

Here is a look at the timeline of events leading up to Anna’s Death.
