William Moldt was reported missing in 1997 at the age of 40, after failing to return home from a night out in Lantana, Florida in the United States.
Palm Beach County Sheriff's Office told the BBC that Mr Moldt is presumed to have lost control of his vehicle and driven into the pond.
Moldt, a 40-year-old mortgage broker, rarely drank, but he had chose to go out that evening in November 1997.
According to The National Missing and Unidentified Persons System, Moldt had gone to the Adult Night Club on the evening of November 7, 1997, and left around 11 p.m.
"The vehicle's exterior was heavily calcified and was obviously in the water for a significant amount of time", Barbera said.
When they pulled it out they found skeletal remains inside.
An image of the submerged vehicle is still available to view on Google Earth.
Moldt's body was found still inside his auto, which had been submerged in the pond near the housing project.
An eagle-eyed resident of Lake Worth, Fla., made the wonderful find on August 28, when he was looking at some satellite images of his neighborhood on the mapping program and noticed a vehicle submerged in a lake near his home, the Florida Sun Sentinel reported Thursday.
A property surveyor looking at Google Earth spotted the auto on August 28 this year.
That person called the current resident on Moon Bay Circle to tell him that there appeared to be a auto behind his home, deputies said in a Facebook post. How Moldt's vehicle became submerged in the pond remains unclear.
The housing development where Moldt's remains were found was reportedly under construction at the time he went missing.
Both the vehicle and the remains were sent to the Medical Examiner's Office for processing.
Moldt had called his girlfriend from the bar at around 9:30 p.m.to say he would be home soon and that was the last contact she had with him.
