"They made the discovery," McQuaig said. "They called 911 and they waited for us to get there."
The bodies were found in a grassy area between the golf course and an adjacent apartment complex, he said.
The names of the victims had not been released Tuesday night, and McQuaig didn't have their ages.
He said the golfers didn't see anyone fleeing after the shots rang out.
Autopsies on the victims were scheduled for Wednesday, he said.
The golf course is mostly lined with apartment complexes in Florida's capital city.
