Cops: Nothing found in landfill search for missing Conn. couple

EASTON, Conn. -- Authorities investigating the case of a missing Connecticut couple have found no human remains after searching a landfill in Putnam, reports CBS affiliate WFSB.

Fifty-five-year-old Jeanette Navin and 56-year-old Jeffrey Navin, of Easton, haven't been seen since Aug. 4. Their car was found in a commuter lot off the Merritt Parkway in Westport Aug. 9 by state troopers, according to Connecticut State Police. It reportedly had a broken window.

Connecticut State police told the station they searched the landfill because it was "an effort to rule it out as a possible location." They say they're continuing to conduct searches, gather evidence, and follow up on leads.

State police and local detectives searched the Bridgeport home of the couple's son Kyle on Wednesday night, and police are calling him a "person of interest" in the case, the station reported. According to the Connecticut Post, Kyle Navin was the last known person to see his parents before they disappeared.

Kyle Navin is listed as an operations manager for the family's refuse company -- his father is reportedly the company's president. Neighbors told the Connecticut Post that Kyle Navin packed up his car and left about a week ago.

State court records show Jeffrey Navin was $2.2 million in debt as of December in connection with a mortgage on a Guilford home. Relatives have denied that their disappearance is related to the debt.

The paper reported that Laura Thompson, the wife of Jeffrey Navin's brother, reported them missing Aug. 7 after her brother-in-law hadn't collected the refuse along his route in several days. She reportedly told police the last time anyone heard from the couple was Aug. 4, when they visited Kyle.

Police reportedly then interviewed Kyle Navin, who told police he last saw his parents on Tuesday morning when they came to visit him. Kyle Navin told police he had a broken back and was unable to work, and told his parents he couldn't go out to dinner with them that night because his back was hurting, according to the paper.

Kyle Navin suggested to police that his parents might have gone to New York for dinner, according to the Connecticut Post.

Easton Police Chief Tim Shaw declined to comment to the Associated Press on what he said remained an "open investigation." Connecticut State Police issued a short press release but did not comment on the case to 48 Hours' Crimesider.

Calls by the Associated Press to J&J Refuse and a cell phone number believed to belong to Kyle Navin were met with busy signals on Friday. He also did not return an email seeking comment.

Prosecutors last week asked state police to take over the investigation. Police obtained warrants to search Kyle Navin's home, the parents' property in Easton, a house they own in Westport and several bank accounts, according to a clerk at Bridgeport Superior Court.
