Investigators and families are haunted by the enigmatic disappearance of veteran boater Randall “Randy” Spivey and his nephew Brandon Billmaier, whose 42-foot Freeman catamaran “Unstopp-A-Bull” was discovered eerily operational in the Gulf of Mexico. Located on December 20, 2025, about 70 miles west of Fort Myers near Marco Island, the vessel was adrift but intact, its engines roaring and transmission locked in gear, cruising pilotless as if on autopilot. This spectral find, coupled with a witness’s startling account, has intensified the mystery, suggesting a split-second tragedy that left no time for distress calls.

Randy, 57, a revered Fort Myers attorney with over 30 years on the water, and Brandon, 33, a Boca Raton trial lawyer emulating his uncle’s path, departed before dawn on December 19 for a routine fishing expedition off Naples. Equipped with GPS trackers, radios, and safety gear, they planned a sunset return. When silence fell, wives Tricia Spivey and Deborah Billmaier alerted the Coast Guard by 11 p.m., triggering a helicopter search. The boat’s spot tracker revealed a normal outbound path but a sudden deviation on the way back, hinting at catastrophe.

A key witness, speaking anonymously to authorities, theorized the sequence: Randy possibly slipped overboard amid choppy return waters, prompting Brandon to dive in heroically. As the unmanned boat surged forward, an abrupt rogue wave—uncommon but possible in the Gulf’s deceptive calm—allegedly slammed them, flinging both farther from reach. This aligns with a puzzling clue: two life jackets absent from the vessel, presumed grabbed and worn in panic. No debris, bodies, or activated beacons were found, baffling experts given Randy’s safety obsession.

The U.S. Coast Guard mounted a grueling four-day operation, scouring 6,700 square miles with helicopters, cutters, and volunteers, equivalent to Connecticut’s size. Suspended at sunset on December 22 amid exhausting conditions and fading odds in 74-degree waters, the effort shifted to passive monitoring. Capt. Corrie Sergent called it a tough call, praising the teams. Now, the FBI leads the missing persons probe, analyzing the boat for forensic hints like tampering or malfunctions, though initial checks show none.

Families endure a shattered Christmas on December 25, 2025. Deborah, in poignant posts, shared Brandon’s infectious excitement that morning, urging respect for the suspension to avoid further risks. Tricia described Randy as a devoted family man and legal advocate for the injured. The Shiner Law Group prays for miracles, while community vigils flicker along beaches. Private searches with drones persist, fueled by funds for marine safety.

This vanishing echoes maritime enigmas, reminding even experts of the sea’s ruthlessness. Was it a freak wave, a medical mishap, or unseen peril? As hope dims, the “Unstopp-A-Bull’s” lone journey symbolizes unyielding questions in Florida’s vast blue expanse.
