But that didn't stop authorities from fairly publicly taking a hard look into the victims' lives and reputations.

For example, investigators went through all of Juan's patient records to determine if there were any former or current patients who'd lodged complaints against him or who'd had any issues with his practice or medical care.

But there wasn't a single person who'd complained about his business.

Investigators also looked into whether Juan's Cuban heritage or any potential connections he might have had with folks affiliated with anti-Fidel Castro activities could be to blame.

But there was absolutely nothing there either in terms of motive.

Next, they delved into Raymond Barrow's life.

And just like they had with Juan, they focused on the fact that he was also of Cuban descent.

They also scrutinized his activities as a bell captain for the Key Biscayne Hotel in Miami.

Because during the 1960s, when he'd started working there, the hotel was known as a hotspot for celebrities and influential figures.

In 1980, the year of the murders, there was a lot of notoriety swirling around the establishment, and at the time, Miami was battling a serious crime wave that mostly involved elements of organized crime, drug trafficking, and people involved in all sorts of sketchy business.

So investigators explored whether Raymond was involved in some kind of illegal activity that had caused him to become a target.

However, he denied such accusations, and there was never anything found that tied him to illegal bad actors.

Meanwhile, authorities used divers to search the waters around the boat ramp and an aircraft to fly over the Kingfish boat ramp parking lot looking for any sign of the murder weapon or vehicles that resembled the suspect's getaway car.

Also around that time, commissioners in Manatee County approved a $10,000 reward for information that could lead to an arrest in the case.

But those funds didn't seem to really move the needle.

Law enforcement was also fielding lots of tips and phone calls from people who claimed to know someone who looked like the man in the composite sketch.

The whole weekend after the crime, investigators' phones were ringing with folks from all over claiming they knew who the guy might be or that they'd seen him previously.

One of those calls came from a couple in Hyde Park, Florida, near downtown Tampa, who said they'd seen the composite sketch in the newspaper and believed they'd been housing a guy who closely resembled the suspect.

That man's name was Richard Lee Whitley.

And when authorities got a hold of the 34-year-old, they quickly learned he had an extensive criminal record for offenses including assault, larceny, sodomy, and most importantly, he was currently on the run from Virginia authorities and wanted for murder.
