Retired NYPD Sergeant Bill Cannon doesn’t mince words. Twenty-seven years walking the bloodiest beats in the Bronx and Manhattan taught him one thing: when a crime scene sails away at 20 knots, the truth usually sinks with it.

On December 9, 2025, the grizzled ex-cop sat down in his Queens kitchen, surrounded by case folders thicker than the Carnival Horizon’s hull, and delivered a blistering 40-minute takedown of the still-unsolved homicide of 18-year-old Florida cheerleader Anna Kepner.

“This wasn’t a drunk teenager who wandered off the Lido Deck,” Cannon growled, jabbing a finger at redacted FBI files spread across his table. “This was a straight-up murder. Anna Kepner was strangled, wrapped in a blanket, and stuffed under a cabin bed like yesterday’s trash while 3,900 passengers ate shrimp cocktail two decks above. And six weeks later, the only suspect is a 16-year-old stepbrother who lawyered up and stopped talking. That’s not an investigation. That’s a stall.”

The Carnival Horizon left Miami on October 31, 2025, carrying what should have been the perfect blended-family celebration: Anna, her father Christopher, stepmother Shauntel Hudson-Kepner, Shauntel’s three children—including the unnamed 16-year-old boy—and Anna’s grandparents. By the morning of November 7, halfway to Half Moon Cay, Anna was dead.

Housekeeping found her at 11:17 a.m. wedged beneath the lower bunk in Cabin 7123, smothered with life vests, a ship-issued blanket twisted around her neck. The Miami-Dade Medical Examiner ruled it mechanical asphyxia—homicide—within 48 hours. Yet today, no arrests. No charges. Just silence, red tape, and a family shredded in two.

Cannon, who spent years working joint task forces with the FBI, says he’s seen this movie before.

“Cruise ships are floating jurisdictions,” he explained, voice rising. “The second that ship crosses 12 nautical miles, it’s international waters. Evidence preservation? A joke. Crew scrubs the crime scene before the body’s cold because the next sailing is in 48 hours. Witnesses scatter to six continents. And the black box—the voyage data recorder that logs every door, every camera, every keycard swipe—gets locked in a Carnival vault until lawyers decide what the public’s allowed to see.”

He flipped open a leaked FBI 302 interview summary dated November 10, 2025:

Subject: “I don’t remember anything after breakfast… I loved Anna… I would never hurt her.”

Cannon snorted. “That’s what they all say when the polygraph tech walks in the room. Kid lawyered up dockside, got shipped to a psych ward, and hasn’t uttered a peep since. Meanwhile the grandparents are screaming that the stepmother’s side of the family had been threatening Anna for months.”

Court filings from Brevard County back that up. Shauntel Hudson-Kepner filed an emergency motion November 17 begging to postpone custody hearings because her son was “under FBI investigation for the homicide of his stepsister.” The motion was granted. The boy remains in a juvenile facility. No charges filed—yet.

Cannon laid out the timeline that keeps him up at night:

10:42 a.m. – Keycard logs show the 16-year-old entering Cabin 7123
10:58 a.m. – Second device logged into the boy’s Snapchat pings on Deck 7, 30 feet from the cabin
11:17 a.m. – Housekeeping discovers Anna’s body
11:45 a.m. – Ship finally notifies the FBI (28-minute delay)

“Twenty-eight minutes,” Cannon repeated, slamming the table. “That’s how long it took for someone to realize a girl was murdered and call the cops. In New York, we’d have had the crime scene frozen in eight. On a cruise ship? They’re worried about the buffet schedule.”

He saved his harshest words for the jurisdictional nightmare.

“FBI has the case because it happened outside the 12-mile limit. But Carnival’s flag of convenience is Panama, so the Panamanians claim jurisdiction too. Meanwhile the ship’s home port is Miami, so Florida wants a piece. You end up with three agencies pointing fingers while the evidence literally sails away.”

Cannon says the black box is the holy grail—and it’s being buried.

“That recorder logs every interior camera, every door sensor, every PA announcement. If the stepbrother dragged Anna into that room, it’s on tape. If someone helped him, it’s on tape. But Carnival won’t release it without a court order, and the court order is stuck in federal limbo because the suspect is a juvenile.”

He paused, voice dropping to a whisper that somehow carried more weight than his shouting.

“I’ve seen mothers wait ten years for justice in cruise cases. Anna Kepner’s family shouldn’t have to wait ten minutes.”

As of December 9, 2025, the FBI’s only public statement remains: “The investigation is active and ongoing.”

Bill Cannon’s final words before the camera cut:

“Active and ongoing is FBI-speak for ‘we’re stuck.’ Anna Kepner was murdered in cold blood on an American-flagged ship full of American citizens. If they can’t solve this one, God help the next girl who disappears at sea.”

The Horizon sails again tomorrow. Same itinerary. Same cabin available for booking.

And somewhere in a redacted file, a 16-year-old boy still can’t remember what happened to his stepsister.
