Siblings and Unanswered Calls 📱: The Lingering Mystery in the Disappearance of Randall Spivey and Brandon Billmaier

As December 30, 2025, dawns with no new developments in the case of missing boaters Randall “Randy” Spivey and Brandon Billmaier, the families continue to grapple with profound grief and unanswered questions. The uncle and nephew—both accomplished attorneys and passionate fishermen—vanished on December 19 during a routine offshore trip in the Gulf of Mexico. With the U.S. Coast Guard having suspended its active search on December 22 after covering thousands of square miles, the investigation has shifted to the FBI as a missing persons case. Yet for siblings, spouses, and extended family, the pain is raw: phones filled with saved missed calls and voicemails from the men remain untouched, as deleting them feels like erasing the last connections to their voices.

These photos serve as poignant reminders of the bond between Randy, 57, a Fort Myers personal injury lawyer and founder of Spivey Law Firm, and Brandon, 33, a trial attorney at Boca Raton’s Shiner Law Group who followed in his uncle’s professional footsteps.

The Day Everything Changed: December 19 Timeline

The trip began like so many before it. Randy and Brandon departed early from Randy’s home dock on Intracoastal Court in Iona, Fort Myers, aboard the 42-foot Freeman catamaran named “Unstopp-A-Bull”—a vessel reflecting Randy’s resilient spirit. Experienced boaters with decades of combined time on the water, they planned a day of bottom fishing and expected to return by afternoon or early evening.

Brandon’s wife, Deborah Billmaier, received a loving text from him that morning: “I love you. I will see you tonight, be back home tonight.” It was the last direct communication from either man. Randy’s wife, Tricia Spivey, similarly anticipated updates but grew concerned when none arrived.

By 7:30 p.m., with no sign of the boat or contact, families alerted authorities. The U.S. Coast Guard launched an immediate response, deploying helicopters and vessels. Just hours later, around midnight on December 20, a helicopter crew located “Unstopp-A-Bull” adrift approximately 70 miles offshore, near Marco Island. The boat was upright, engines running in gear, lights on—but eerily empty. No signs of damage, struggle, or distress. Notably, two life jackets were missing, offering a sliver of hope that the men had donned them before entering the water.

Phones, wallets, and personal items remained aboard, intact. This discovery intensified the mystery: How could two seasoned mariners disappear from a functioning vessel without activating the EPIRB beacon or sending a mayday?

Family’s Digital Lifeline: Refusing to Delete Voicemails and Calls

In the days since, family members—particularly Brandon’s siblings and Randy’s children—have turned to their phones for solace. Saved voicemails from casual check-ins, birthday messages, and fishing trip recaps are replayed endlessly. Missed calls from the weeks leading up to December 19 sit untouched in call logs, as deleting them would feel like severing a final thread.

Deborah Billmaier, Brandon’s wife of 15 months, has spoken of replaying his last text repeatedly. Siblings describe gathering to listen to old voicemails together, finding comfort in hearing the men’s laughter and plans. “It’s all we have left of their voices right now,” one relative shared anonymously. These digital remnants have become sacred, a way to keep Randy and Brandon present amid the uncertainty.

The families have expressed gratitude for the massive response but heartbreak over the suspended search. In a statement, they noted: “Few people cared more about others’ safety than Randy and Brandon. We know they would respect the difficult decision to suspend active efforts.”

Pre-Trip Preparations: The Shopping List That Raises Questions

Adding to the emotional weight is a recently revisited pre-trip shopping list, reportedly compiled by Randy and Brandon in the days before departure. Family members reviewing belongings and notes found references to routine preparations: bait, ice, fuel checks, snacks, and safety gear. What has “changed everything” for some relatives is the meticulous nature of the list—consistent with Randy’s known caution as a boater.

What to Pack for a Charter Fishing Trip

This photo evokes the organized planning the men undertook, highlighting how out of character any oversight would be. The list included extra life jackets, emergency provisions, and weather checks—details that make the empty, running boat even more perplexing. Investigators have examined these items as part of the FBI probe, exploring whether something unforeseen overrode their careful habits.

The Massive Search and Shift to FBI Investigation

The Coast Guard’s effort was unprecedented: over 6,700 square miles searched, involving aircraft, cutters, and partner agencies like the Lee County Sheriff’s Office and Florida Fish and Wildlife. Dozens of volunteer boats joined, some traveling hundreds of miles.

Captain Corrie Sergent called suspending the search “the hardest decision I’ve ever made,” offering condolences while noting exhaustive coverage. The FBI now leads, examining the boat forensically and pursuing all angles—from accident to rarer possibilities.

Shiner Law Group, Brandon’s firm, issued a statement: “We are deeply saddened… Brandon is a valued colleague and friend. We pray for their safe return.”

A Community Holds Vigil

Prayer vigils continue in Fort Myers and Boca Raton. Deborah hopes for a “Christmas miracle,” while Tricia pleads for answers. The families urge anyone with information—perhaps spotting the boat or unusual activity—to come forward.
