“The family is looking for help, and we are reaching out to as many resources as we can and doing our due diligence to find them,” Shaw said.
Florence Eastwood said she didn't know her Staples Road neighbors, but knew something was wrong when she saw a parade of police cars on her street.
"We saw all these police cars going by," Eastwood said. "Like one or two came and we thought there's got to be a problem somewhere and then later on another police car came."
A vehicle belonging to the couple was found by Connecticut State Police on Aug. 9 in Westport, just off exit 42 of the Merritt Parkway. A window of the car was smashed.
"We're not sure if it’s tied to the investigation. It looks like it was done that night, the night before," Shaw said.
Easton police said they are working with other agencies to find them. They worked throughout the past weekend, but came up with nothing.
“I would say yeah, it does become more suspicious,” Shaw said when asked if the case becomes more suspicious as the days go on.
They said they are looking at phone records and finances. According to state court records, Jeffrey Navin is in debt for more than $2 million connected to a mortgage on a Guilford home that hasn't been paid in years.
Anyone with information about the Navins was asked to call the Easton police at 203-268-4111.
