EASTON - Kyle Navin, the son of an Easton couple missing for seven weeks, appeared in court on Thursday.
As of Thursday, Navin is only facing a federal gun charge. He pleaded not guilty to that charge.
Police say that Navin is a person of interest in his parents' disappearance. He will stay in jail for now.
Jeffrey and Jeanette Navin have been missing since Aug. 4 from their home in Easton.
Five days later, police found the Navins' truck in a commuter lot off of Merritt Parkway. The truck reportedly had a bullet hole and blood inside.
Investigators say Navin has given conflicting stories about the whereabouts of him and his parents that week.
In addition to guns, officers found receipts for bleach and stain remover in Navin's home. Court documents also reveal a text message conversation between Navin and his father the day he went missing.
"Did you hurt mom?" Jeffrey Navin reportedly asked. After his son said no, Jeffrey Navin allegedly texted, "I go home and get framed for murder, U R setting me up."
It's the two guns police found in Navin's house that led to the weapons charge.
Navin only said "not guilty" in court today and walked out of the courtroom with a limp.
