The grieving father of Anna Kepner is calling for justice if it is determined that his stepson is responsible for the tragic death of his 18-year-old daughter during a Carnival cruise. However, he stopped short of confirming whether he believes his stepson played a part in the young cheerleader’s untimely demise.

“I cannot support my stepson’s actions,” expressed Christopher Kepner, 41, in an interview with People magazine.

“He must be held accountable, and I will ensure that justice is served,” he added emphatically.

The high school senior was enjoying a vacation aboard the Carnival Horizon with her extended family, which included her father, stepmother, siblings, stepsiblings, and grandparents. Tragically, on November 7, Anna was discovered deceased.

Her body was found hidden beneath her cabin bed, wrapped in a blanket and covered with life vests, casting a shadow of mystery over the circumstances surrounding her death.

The FBI has offered no updates on its investigation, but court filings from an unrelated case suggest that Anna’s 16-year-old stepbrother, who was sharing a cabin with her, is being eyed as a potential “suspect.”

“He was a normal kid,” Kepner said of his stepson, adding “I would’ve never thought that any of this would’ve happened.”

The grieving father said he last saw his daughter alive on Nov. 6 during a family dinner aboard the Carnival ship, and that her corpse was found the following day by a housekeeper, the outlet reported.

But when asked by the publication whether his stepson was involved in Anna’s grisly death, he replied, “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,” the devastated dad said.

Anna’s death was ruled a homicide, with her death certificate revealing she was “mechanically asphyxiated by other person(s)” on Nov. 6, ABC News reported.

Her 14-year-old younger brother reported overhearing “yelling” and “chairs being thrown” while Anna and her stepbrother were alone in their stateroom, which the three siblings shared during the cruise.

He unknowingly slept feet away from his sister’s concealed corpse the same night she was killed. 

Joshua Westin, Anna’s ex-boyfriend, claimed she confessed she “didn’t feel safe around” her stepbrother months before her death, according to his father.

Westin also accused the stepbrother of sexually harassing and having a twisted obsession with Anna, but said she stayed quiet “because she was scared that he would do something to her,” Westin’s dad said.

Westin’s father also alleged that the stepbrother “always carried around a big knife.” 

“He’s like infatuated, attracted to her like crazy. He always wanted to date her,” he said.

Anna, a devout Christian who was just baptized in May, was set to graduate from the Temple Christian School in Titusville, Florida this school year.

She aspired to join the US Navy and eventually become a K9 police officer.
