The son of a missing Easton, Connecticut couple, has been arrested on a federal gun charge, and sources have told NBC Connecticut he's a person of interest in his parents' disappearance.
Kyle Navin, 27, of Bridgeport, has been charged with possession of a firearm by someone who is illegally using or addicted to a controlled substance, according to the U.S. Department of Justice. He appeared in federal court Tuesday afternoon.
Police searched Kyle Navin's home last month as part of the investigation into his parents' disappearance.
They discovered two guns, numerous rounds of ammunition, empty heroin bags, hypodermic needles and empty bottles of oxycodone and other prescription drugs, according to the U.S. Department of Justice. A search of his cellphone revealed text messages discussing Navin's use of heroin, oxycodone and Xanax.
Investigators also found a receipt from a shooting range dated Aug. 5, the day after his parents, Jeffrey and Jeanette Navin, disappeared from their Easton home.
Jeffrey Navin, 56, serves as president of the J&J Refuse sanitation company in Westport, while Jeanette Navin, 55, works as a school library aide in Weston. Police said they had recently moved to Easton from Westport.
Kyle Navin works as operations manager of J&J Refuse and told police the family was in the process of selling the company, according to search warrants obtained by NBC Connecticut.
Police records indicate Kyle Navin saw his parents the morning they vanished. According to the warrants, Jeffrey and Jeanette Navin visited him and asked to take him out to dinner, but Kyle Navin said he had a broken back and declined.
That was the last anyone heard from Jeffrey and Jeanette Navin.
No phone calls have been made from the couple's cell phones since the day they disappeared, according to search warrants. Those phones have since been turned off.
Five days after the couple disappeared, a state trooper found their pickup with a broken window in a Westport commuter lot, authorities said. Investigators have taken more than a dozen swab samples from the vehicle, according to the search warrants.
As part of the investigation, crews have scoured the Putnam Ash Residue Landfill, a 186-acre site operated by Wheelabrator Technologies used to dump ash from all the state's waste-to-energy plants.
About a week before the Navins vanished, a judge denied Jeffrey Navin's motion to reopen a case appealing more than $2.2 million in debt on a $900,000 Guilford home. Other relatives have said they don't believe the couple's finances factored into their disappearance.
Police have also searched the couple's current and former homes and one of their bank accounts.
It's not clear if Kyle Navin has an attorney. He could face up to 10 years in prison if convicted.
Anyone with information about the case is asked to call state police at 860-685-8190. All calls will remain confidential.
