The Carnival Horizon glided through the moonlit Caribbean, its decks alive with oblivious revelry, while in the dim underbelly of Cabin 1423, shadows lengthened into something far more sinister. Just weeks after 18-year-old Anna Kepner’s lifeless body was discovered stuffed under a bunk bed – wrapped in a blanket and shrouded by life vests – new exclusive details from her ex-boyfriend, Josh Tew, are ripping open the veil of secrecy surrounding her death. In a bombshell interview, Tew recounts spotting what he believes was his half-brother – the same 16-year-old stepbrother now under FBI scrutiny – loitering suspiciously in the hallway outside the cabin at 11:03 p.m. on November 6, mere hours before the nightmare unfolded. Adding to the mounting evidence of foul play, investigators uncovered a small, personal item belonging to Anna on the cabin floor – a trinket that didn’t match any luggage in the room, hinting at a frantic struggle or deliberate staging.

Josh Tew, 19, met with our team at a windswept pier in Cocoa Beach, his gaze fixed on the restless Atlantic that had claimed his first love. “I wasn’t there, but pieces started falling into place after I talked to Connor,” Tew said, referring to Anna’s 14-year-old biological brother. Phone records and timestamps from the ship’s internal messaging system, reviewed by federal agents, place Tew in a late-night video call with Connor, who was bunked in an adjacent cabin with their parents. At 11:03 p.m., as the ship churned toward Miami, Connor’s frantic texts painted a picture of unease: a figure pacing the corridor, lingering too long near the door to Anna’s shared quarters. “He said it was Tim – my half-brother from Shauntel’s side – just standing there, not moving, like he was waiting for something,” Tew revealed, his voice dropping to a whisper. “Connor didn’t think much of it at first, but now… it haunts him. Tim knew Anna was alone in there after she came back from the deck.”

Timothy “Tim” Hudson, the 16-year-old stepbrother sharing the cramped cabin with Anna, her brother Connor, and a younger stepsister, has been thrust into the spotlight as the prime suspect in the FBI’s intensifying probe. Court filings from Shauntel Hudson’s ongoing custody battle with her ex-husband, Thomas Hudson, explicitly name “T.H.” as under investigation for the “suspected murder” of Anna, with agents warning that charges could follow. The motion, filed November 18 in Brevard County Family Court, cites the “extremely sensitive and severe circumstance” of Anna’s death aboard the Horizon, which docked in Miami on November 8 amid a swarm of federal agents. No formal charges have been filed, but sources close to the case say Hudson has been placed with a neutral third party pending the outcome, his movements restricted as forensic teams comb through over 500 hours of surveillance footage.

Tew’s account aligns chillingly with emerging details from the crime scene. During the cabin sweep on November 7 morning – roughly 12 hours after the hallway sighting – a crew member not only discovered Anna’s body but also noted a small silver locket on the linoleum floor near the bunk. The heart-shaped pendant, engraved with Anna’s initials “A.M.K.” and a tiny cheerleading pom-pom charm, was a gift from her biological mother, Heather Wright, for her 18th birthday just months prior. Crucially, it wasn’t in Anna’s packed luggage or carry-on, which had been inventoried by her father, Christopher Kepner, before boarding in Miami on November 2. “It was her most prized possession – she never took it off,” Wright told our team in an emotional sit-down, her hands trembling as she clutched a photo of Anna wearing it. “Finding it on the floor, snapped open like it was yanked in a fight… that’s no accident. Someone tore it from her neck.”

The locket’s discovery has forensic implications that could prove pivotal. Miami-Dade lab technicians are rushing DNA swabs from its clasp and interior photo compartment – a faded snapshot of Anna and Connor at a Titusville beach bonfire. Preliminary reports, leaked to CBS News and corroborated by our sources, show no drugs or alcohol in Anna’s system, ruling out accidental overdose, but confirm asphyxiation via a “bar hold” – an arm barred across the throat, leaving bilateral bruises consistent with a prolonged struggle. No signs of sexual assault were found, but the body’s positioning – fetal-curled, partially unclothed, and concealed – screams cover-up. “That locket wasn’t just jewelry; it was a lifeline to her real family,” Tew added. “If Tim was lurking outside, waiting for her to be alone… God, what did he do when she let him in?”

Tew’s connection to the Hudson family adds layers of tangled intimacy to this tragedy. Born to Shauntel Hudson during her first marriage, Tew shares a half-sibling bond with Timothy through their mother, though years of family rifts have strained it. He dated Anna for nearly a year, their romance blooming at Temple Christian School amid cheer practices and late-night study sessions. “We broke up amicably in May – young love, you know? But I was invited on that cruise originally,” Tew confessed, regret etching his features. “If I’d gone, maybe I’d have seen Tim’s obsession up close. Anna told me everything: the way he’d follow her in the house, borrow her clothes without asking, even slip notes under her door saying she was ‘his sunshine.’ She laughed it off at first, but it scared her.”

Those fears weren’t unfounded. In our interview, Tew recounted a July FaceTime incident that still gives him nightmares: Anna dozing mid-call, phone angled on her pillow, when the door creaked open. “Tim crept in, climbed right onto the bed, hovering over her like a predator,” Tew said, his fists clenching. “I screamed her name until she bolted awake, shrieking. He ran, but not before she saw the knife clipped to his belt – that big hunting blade he always flashed like a trophy.” Tew alerted Christopher and Shauntel immediately, but claims they brushed it off as “boys being boys.” Steven Westin, Tew’s father, backed this in a separate sit-down with Inside Edition, adding, “Anna was terrified. She crashed at our place half the time just to avoid him. We begged her parents to intervene – they chose denial.”

The cruise amplified these tensions into a pressure cooker. Anna, a straight-A senior eyeing a military future, had posted bubbly TikToks from the Horizon six months earlier, twirling in a sundress with the caption, “I wanna go back – adventure awaits!” But this trip, meant as a blended-family bonding voyage, soured fast. Connor’s texts to Tew describe a blowout the night before: November 6, post-dinner, Anna retreating to the cabin after feeling queasy. Locked inside with Tim – parents and the younger girl at a deck show – Connor heard it all from the adjoining room. “Yelling, like ‘Shut the hell up!’ Chairs scraping, banging – then silence,” Tew relayed. “Connor pounded on the wall, but Tim yelled back to stay out. By 11:03, when Connor peeked into the hall, there was Tim, pacing like a caged animal.”

FBI dive teams and Carnival’s security logs paint a timeline damning in its precision. Anna’s last confirmed movement: 10:32 p.m., swiping into the cabin alone after a deck stroll with Connor, where she’d FaceTimed Tew one final time, her laughter light despite the nausea. At 10:37 p.m., infrared footage catches that ghostly reflection in the doorframe – a silent sentinel, now potentially Tim post-confrontation. By 11:03 p.m., Tew’s half-brother allegedly loiters, perhaps retrieving or disposing of something. Autopsy pegs time of death at 11:17 p.m. – four minutes after the last muffled thump Connor swears he heard. The locket, snapped and discarded, could carry trace evidence: skin cells, saliva, even blood from a defensive scratch.

The Kepner-Hudson family’s fissures run deep, fueling speculation of buried secrets. Heather Wright, Anna’s estranged mother, learned of the death via Google – a gut-wrenching search for “cruise ship death Florida teen.” Barred from the November 20 celebration of life at The Grove Church – a vibrant affair in Anna’s favorite blues and yellows, with mourners pressing thumbprints to her portrait – Wright attended incognito. “I placed that locket on her neck myself, whispering promises of freedom,” she said, tears streaming. “Now it’s evidence in her murder.” Christopher Kepner, Anna’s father, has gone silent, but sources say he’s cooperating, haunted by the blended-home he built. Shauntel Hudson, cleared of wrongdoing by the FBI, faces a custody war where her son’s fate hangs in the balance.

As agents pore over key-swipe data – showing Tim’s erratic entries that night – and the life vests for DNA traces, Tew clings to Anna’s memory. “She was my light – bubbly, fierce, always cheering everyone on,” he said, placing a sunflower at her makeshift memorial outside Temple Christian. Vigils in Titusville flicker with blue candles, signs reading “Justice for Anna – No More Shadows.” The hallway loiterer, the misplaced locket: threads in a web of obsession and violence. Fourteen minutes from yell to silence, a life snuffed out at sea. The Horizon sails empty decks now, but its corridors whisper of a girl who deserved the stars, not the abyss.

In the wake, questions multiply like waves: Was the locket a trophy dropped in haste? Did denial doom Anna? And Tim – half-brother, suspect, enigma – will the truth surface before the tide turns? For Tew, the answer is personal: “I saw him there, in that hall. Now I need the world to see what he did.”
