A mysterious underwater acoustic signal detected just 12 miles from where the empty boat of missing Florida men Randy Spivey (57) and Brandon Billmaier (33) was found has reignited speculation and hope in their disappearance. Viral social media posts claim the “chilling signal from the deep” could be a distress call from the uncle and nephew, lost at sea since December 19, 2025.

The two experienced attorneys and avid fishermen set out from Fort Myers on a routine trip in the Gulf of Mexico aboard their 42-foot Freeman vessel. When they failed to return, a massive search ensued. The Coast Guard located their boat drifting empty about 70 miles offshore on December 20 – engine possibly running, but no sign of the men. Notably, two life jackets were missing, offering a sliver of hope they donned them before whatever incident occurred.

An extensive multi-day search involving air, sea, and partner agencies covered vast areas but yielded no trace. The U.S. Coast Guard suspended active operations on December 22, citing exhaustive efforts, though the case was handed to investigators, with the FBI ready to assist if needed. Families spent a heartbreaking Christmas without answers, clinging to theories ranging from mechanical failure to falling overboard.

Now, weeks later in early January 2026, unverified reports of an underwater ping or signal near the ghost boat’s location have gone viral, fueling sensational claims of survival or a final call for help. Some speculate it could stem from an emergency beacon, personal locator, or even submerged equipment activating. Private search efforts and online communities have amplified the buzz, urging renewed dives or sonar scans.

However, authorities have not confirmed any such signal. Coast Guard statements emphasize the original search’s thoroughness, and no official reactivation has been announced. Experts note that false positives in ocean acoustics are common – from marine life, debris, or unrelated vessels.

The case remains a presumed tragedy, highlighting the Gulf’s dangers even for seasoned boaters. Randy, a prominent Fort Myers attorney, and Brandon, his nephew from South Florida, were described by loved ones as cautious and prepared. Theories persist: a sudden wave, medical emergency, or propulsion issue leading to man overboard.

As families continue private vigils and awareness campaigns, this latest “signal” offers emotional whiplash – a mix of desperate hope and painful reminder of unresolved grief. While unlikely to change the official outcome, it underscores how mysteries at sea captivate and haunt us.

Until concrete evidence emerges, Randy Spivey and Brandon Billmaier remain missing, their story a sobering call for boating safety and swift emergency protocols.
