WASHINGTON — The young woman who tragically passed away on the Carnival Horizon cruise ship on Saturday has been identified by her family and the local community as 18-year-old Anna Kepner from Titusville, Florida.

Kepner reportedly lost her life while on a Caribbean cruise that had departed from Miami. The ship returned to Port Miami as originally planned that morning.

Specific details about the cause of her death have not been disclosed.

ABC News confirmed Kepner’s identity with her family, who expressed their wish for her to be remembered for her kindness and vibrant spirit.

Temple Christian School in Titusville also shared tributes to Kepner on its Facebook page. 

Carnival Cruise Line said it was working with the FBI Miami office to investigate the incident.

“Our focus is on supporting the family of our guest and cooperating with the FBI,” the company said in a statement.

FBI Miami spokesperson James Marshall said the office responded to the scene, but he said no further information was available.

Kepner’s family described her to ABC News as a “happy, bubbly, straight-A student” who was preparing to graduate high school in May and had recently begun the process of joining the military.

“When she walked into a room, she would light it up,” her family told ABC News. “If you were sad, she’d make you laugh. She would joke around and be the funniest little person in school.”

“She was the best child you could ever meet,” her family told ABC News. “We’ll always remember her for who she was.”

Authorities have not said how or where on the ship Kepner died, and the investigation remains ongoing.
