State Police combed through a Bridgeport home Wednesday evening, looking for evidence in the case of a missing Easton couple, the owners of a Westport trash-collection firm.

At the request of Bridgeport State’s AttorneyJohn Smriga, the State Police Western District Major Crime Squad began to investigate the disappearance of Jeffrey andJeanette Navin early this month.

Smriga declined comment, but State Police said the initial request for assistance had come from Easton police.

Investigators, accompanied by a State Police Major Crime Squad truck, were at a home on Aldine Avenue in Bridgeport until late Wednesday. State Police spokeswoman Kelly Grant confirmed the search of the home, belonging to Kyle Navin, was related to the search for the missing couple, who last were seen Aug. 4.

Kyle, the Navins’ son, is listed as operations manager on the website of J&J Refuse, their Westport business.

Jeffrey Navin, 56, is the president of J&J Refuse. Jeanette Navin, 55, is a Weston Intermediate School library paraprofessional.

A pickup truck belonging to the couple was found Aug. 9 in a commuter parking lot off Exit 42 of the Merritt Parkway in Westport.

Antonio Cuevas, a neighbor of the Bridgeport home under investigation, said Kyle Navin lives there with his wife and two dogs.

“He’s a very nice guy; we talk very little,” said Cuevas. “Him and my kids speak, because they both played lacrosse in school.”

Cuevas added that he hadn’t seen Kyle Navin in about week, and news about his parents’ disappearance came as a shock.

Kyle Navins purchased the Brooklawn area home in 2012 for $125,000 and previously lived with his parents at their Weston home, according to public records.
