THE wife of a lawyer who disappeared alongside his uncle has revealed a theory that could explain how their empty boat was found 70 miles offshore with the engine still running.

The uncle-and-nephew duo vanished during a fishing trip in Florida under what officials have described as unusual circumstances.

Randall Spivey, 57, and Brandon Billmaier, 33, were last seen on December 19 before they never made it back.

They were reported overdue to Coast Guard Sector St. Petersburg at 8 pm, authorities said.

Just after midnight, a Coast Guard helicopter spotted their boat adrift and still in gear about 70 miles west of Fort Myers.

The men were nowhere on board.

Deborah revealed his final text to her: “I love you, and I’ll see you tonight. I’ll be back home tonight,” ABC affiliate WPBF reported.

The boat is named “Unstoppable,” and it was found about 70 miles offshore around 12 am, according to the account shared by Billmaier’s wife, Deborah Billmaier.

Deborah said the Coast Guard believes one man fell overboard and the other went in after him, not realizing the engine was still running.

“So they jumped in the water, and the boat was still going, kept moving away from them,” Deborah explained.

“There was no way the two men could catch up to the moving 42-foot boat,” she added.

Both men were attorneys, and Billmaier was Spivey’s nephew, according to the Shiner Law Group.

David I. Shiner of the Shiner Law Group in Boca Raton confirmed Billmaier was a trial attorney at the firm.

Deborah said the two families were inseparable, often traveling and fishing together, and Brandon had followed his uncle into law.

She said Brandon hoped to eventually join Spivey’s firm.

Billmaier was born in Ohio and raised in Michigan, according to his bio on the firm’s website.

He earned his bachelor’s degree, Juris Doctor, and Master of Business Administration degrees from the University of Toledo.

Away from work, he enjoyed fishing and lobstering in the Florida Keys, played pickleball, and focused on a healthy lifestyle, the bio said.

Deborah reflected on how they met in 2020, saying, “Our love story, it’s pretty incredible we met in 2020.”

“From the moment I first met him, the way he speaks, carries himself, talks about others, cares about others, it’s just something indescribable,” she said.

Now 31, Deborah said she keeps thinking about their last dinner together on a slow Thursday night: “You know, sometimes just those simple moments are the best.”

She said she believes the Coast Guard did everything possible, and finds comfort in the idea that he spent his final hours doing what he loved.

“He loved fishing,” she said. “He lived for it, he lived for his family, for me.”
