A family member of Anna Kepner, who passed away on a Carnival Cruise vessel in early November, revealed that the young woman “struggled for her life” amid reports that her death has been classified as a homicide.

Anna, who was 18 years old, was discovered deceased on November 7 aboard the Carnival Horizon during a family holiday. Her demise has been determined to be a homicide due to “mechanical asphyxiation,” as reported by ABC News. However, no suspect or person of interest has been identified by authorities yet. The FBI is currently investigating the circumstances surrounding Anna’s death.

Family members stated that Anna’s body was found in her cabin on the Carnival Horizon, a room she shared with her stepbrother.

Krystal Wright, Anna’s aunt, expressed to Fox 35 Orlando her belief that the 18-year-old cheerleader put up a fight.

“I know Anna fought. I know she fought for her life, so it’s rough. It’s rough,” Wright said.

Anna’s aunt said she’s frustrated that there’s still no arrest, despite the death reportedly being ruled a homicide.

“We don’t understand why, if the boy is a suspect, why has he not been charged yet? What’s happening there?” Wright asked. “It’s turmoil. We’re just sitting here waiting.”

While authorities haven’t announced any criminal charges, stepmother Shauntel Kepner revealed that Anna’s 16-year-old stepbrother has been eyed as a suspect. She made the claim in a court filing amid a legal battle with her ex-husband Thomas Hudson.

Anna’s 15-year-old ex-boyfriend recalled an instance where the stepbrother allegedly tried to get on top of her during a FaceTime call.

“When I was on FaceTime with her, and she was lying down, and her brother tried to go on top of her,” the ex-boyfriend said.

The ex-boyfriend reported the incident to Anna’s parents, saying she had previously complained about being “uncomfortable” around her stepbrother. Anna’s ex-boyfriend said he’d be on the cruise had they not broken up.

In a court filing, Christopher Kepner, Anna’s father, told People that “I want him to face the consequences … I will be fighting to make sure that does happen.”

“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,” Kepner said. “And I would’ve never thought that any of this would’ve happened.”
