BRIDGEPORT - The son of an Easton couple who police say went missing last month is in federal custody Tuesday evening after being arrested on a weapons charge.

Kyle Navin, 27, of Bridgeport, was arrested on a charge of unlawful possession of a firearm. Police say he is addicted to several drugs. There was no mention in his arrest documents that Navin is connected to his parents' disappearance.

Authorities say they recovered two guns and several drugs from his home. The seized drugs include heroin, oxycodone and Xanax.

Navin was named a person of interest in the case of his missing parents, Jeffrey and Jeanette Navin. Police say family members reported the couple missing Aug. 4. State police say a truck belonging to the couple was located at a commuter lot off of Route 15 in Westport.

Police say there have been some inconsistencies with Navin's story of the last time he saw his parents. They say the 27-year-old was the last person to have any contact with Jeffrey and Jeannette Navin.

Police say records show the last time the couple's cellphones were in use was in or around Kyle Navin's home in Bridgeport. They say the times the phones were last active do not match the times Kyle had provided of when he last had contact with his parents.

Police also say a texting exchange between Kyle and his father show Jeffrey had asked his son if he had hurt his mother, to which Kyle said, "No."

Police also say they found drugs and a receipt from The Home Depot dated Aug. 5, showing that Navin had bought bleach, drain opener, stain remover and cleanup bags.

A hearing is expected to be held Thursday to determine whether he can be released on bond.
