The passenger who tragically lost her life aboard the Carnival Horizon has been identified by her family as 18-year-old Anna Kepner.

Carnival Cruise Line has confirmed to Fox News Digital that they are currently working alongside federal investigators to probe the circumstances surrounding the passenger’s death during the ship’s latest journey, which concluded in Miami on Saturday morning. Anna Kepner’s passing was also confirmed by her mother through a Facebook post.

An FBI spokesperson stated that agents were on-site when the ship docked over the weekend, and the investigation is still active.

“I can confirm that the FBI has responded to the scene,” the spokesperson told Fox News Digital. “As this is an ongoing investigation, no additional details can be provided at this time.”

The FBI did not say what led to the investigation or whether foul play is suspected.

Kepner’s family told ABC News that the 18-year-old was going to graduate high school in May and had dreams to join the military.

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

“She had just finished taking the test to join the military…She was already talking to recruiters and had chosen her career path. She wanted to do something that would help her community,” they added.

Kepner was also heavily involved within her community and volunteered in her grandparents’ 55+ neighborhood as well as helping local businesses in Titusville, Florida, where she’s from.

“She was a people person,” her family said. “She loved being around people. She had that type of energy that just drew you in with her smile and the way she carried herself. She was such an easy person to talk to.”

Kepner was a member of her high school’s varsity cheerleading team and enjoyed spending time near the water, as she had her scuba certification and boating liscense, according to her family.

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

Temple Christian School, where Kepner went to school, described her in a Facebook post as “a bright, kind-hearted young woman whose presence brought warmth and energy into the classroom.

Former FBI Special Agent Nicole Parker told Fox News Digital that cruise ship death cases can be “very complex” for law enforcement.

Parker said that the bureau typically assumes jurisdiction when potential crimes occur aboard cruise ships in international waters.

“The FBI has jurisdiction to handle cases when a crime occurs in international waters,” Parker said. “It’s very complex — it falls under what’s called special maritime jurisdiction laws that mandate this. For example, if a cruise departs from Miami, that gives FBI Miami jurisdiction if it’s returning in or out of a U.S. cruise port. And if the alleged crime occurred in international waters, then that’s the FBI’s responsibility.”

Parker, who spent years investigating maritime cases, said such probes often require complex coordination between agencies and cruise line officials.

“Basically, Obama signed this law and if there are certain crimes or allegations that occur on cruise ships, then the FBI has jurisdiction to work them,” Parker added.

“I actually discuss this in my book — crimes on the high seas were part of my responsibilities at the bureau,” she said. “It was a lot of work. I was the only one doing it, but those cases covered multiple things — probably eight or nine different categories. The FBI has the first right of refusal for those incidents, so the cruise line security officers would call me at all hours of the night, and I’d have to listen and determine whether we’d take the case.”
