GREEN COVE SPRINGS, Fla. – Clay County deputies and family members continued their countywide search Thursday for a missing 65-year-old man.
Keith Edward Pereau was last seen Monday morning near Clay Street in Fleming Island, according to the Clay County Sheriff's Office.
On Thursday, both family and deputies searched by boat in the St. Johns River.
"We’ve just been cruising up and down the St. Johns River. We left the boat dock in front of Green Cove (Springs)," said Frank Pereau, Keith Pereau's son. "We cruised all up and down the banks of the St. Johns, past the base."
News4Jax spoke with the missing man's sons, Frank Pereau and Kirk Pereau, at Whitey's Fish Camp in Clay County after they were on the river for hours.
"He went out on the boat on Sunday and his boat returned," Kirk Pereau said.
Frank Pureau said he spoke with his father on Sunday before he went out on the boat with friends.
"I'll say this, I got a phone call from him at 5:08 or 5:09. I was supposed to be on a boat with him. But I said, 'Have fun.' I got a call from him at 1:40 that (Monday) morning," Frank Pereau said. "The only people that was on that boat was his girlfriend, two other males, two other females. That's all we know."
When asked whether they had been able to talk to the people on the boat, Keith Pereau's sons said, "That's all we can say." Pereau's girlfriend declined to comment due to the ongoing investigation.
The Sheriff’s Office is investigating the boat ride. Deputies said there have been few clues in Keith Pereau's disappearance, only saying he wasn't alone in the boat and the boat was found somewhere.
"We have no stray boat. We have no abandoned vehicles," said Sgt. Chris Padgett. "We don’t have things of that nature that would say he was driving down the road and broke down and disappeared or a boat that’s capsized in the river."
According to the Sheriff's Office, there was no sign of foul play inside Keith Pereau's home. But no one seems to know what happened to the father, grandfather and well-known developer.
In addition to searching miles of the river, Keith Pereau's family has spent the last several days canvassing Fleming Island, putting up flyers at homes and businesses.

Pereau's sons said they're also using drones to search the area and asking fishermen to check the shoreline.
"If you see anything suspicious, anything that doesn’t look out of the ordinary, just maybe take a look and call local authorities," Kirk Pereau said.
Keith Pereau's son, Don, said they won't stop searching until their father is found.
“Seconds turn to minutes. Minutes turn to hours. Hours turn to days. Days can turn to months and months, and months could turn to years. We want an answers," he said. "We want to find him and time is wasting. If you have any clues, please let us know."
Keith Pereau was described by deputies as having blue eyes and gray hair, being 5 feet 10 inches tall and weighing about 205 pounds.
Anyone who has seen him or has any information about his disappearance is asked to call the Sheriff's Office at 904-264-6512, or dial or text 911.
