The month before his parents disappeared, police say Kyle Navin wrote that he had the "perfect plan" to get "$ for life."
Then, a few days before they vanished, Navin's mother confided in a friend that she and her husband planned to cut him out of their will.
Now, the adult son of a trash-hauling businessman and a school library aide faces allegations he killed his parents and dumped their bodies in the yard of a vacant home in a well-to-do Connecticut town.
State police said Navin, of Bridgeport, faces two counts of murder and murder with special circumstances in the deaths of his parents, who had been missing since August 4. His girlfriend was charged with conspiracy to commit murder and hindering prosecution.
The bodies of Jeffrey and Jeanette Navin, of Easton, were found Thursday outside a vacant home in neighboring Weston.
According to an arrest warrant affidavit for Navin's girlfriend, Jennifer Valiante, police say Jeanette Navin had been distraught over the situation with her son in the days before she and her husband disappeared.
Jeanette Navin told a longtime acquaintance her relationship with her son had been "very tempestuous" and that she suspected he was abusing drugs, according to the affidavit. She also confided that the couple had purchased a home for their son but he was failing to pay the mortgage and taxes.
Navin then told her friend the couple had planned to cut Kyle, 27, out of their will, sell their trash-hauling business and leave their son without any financial support from the family, according to the affidavit.
Investigators also reviewed text messages sent between Valiante and Kyle Navin before his parents vanished.
In one July exchange, he mentioned a plan to "solve every single problem and give us a wealthy amazing life."
She replied: "I hear ya. It sounds very good I just don't know."
After a few exchanges, he wrote, "Wipe out the infection and get $ for life. It's perfect plan."
Navin's lawyer Eugene Riccio said Saturday morning that he expects his client will be served with arrest papers by Connecticut State Police sometime this weekend. Navin could be arraigned as soon as Monday when the 31-year-old Valiante, who was arrested Friday, is also expected to be arraigned, he said.
Navin is currently being held in a federal prison in Rhode Island on a weapons charge, Riccio said. He declined to comment on the murder charges.
On Friday, Assistant U.S. Attorney Tracy Dayton said there was evidence, including the discovery of the remains, that "very strongly suggests" that Navin killed his parents. Her comments came during a hearing on the weapons charges.
The Navin's pickup truck was found with a shattered window on Aug. 9 in a commuter parking lot in Westport. Jeffrey Navin, 56, was president of J&J Refuse in Westport. Jeannette Navin, 55, was a school aide in Weston.
In the arrest warrant affidavit for Valiante, investigators described DNA evidence found in Kyle Navin's truck and his basement.
Blood found along with a bullet hole on the front passenger seat of his 2000 Chevrolet K2500 tested positive for his mother's blood, according to the warrant. In Kyle Navin’s basement, police found blood stains on a rug that tested positive for both his blood and his father's blood.
Kyle Navin was arrested on the federal weapon charge Sept. 8 after authorities say they searched his Bridgeport home and found two firearms, ammunition and evidence he was using heroin, oxycodone and other controlled substances. He has pleaded not guilty to possession of a firearm by an unlawful user of a controlled substance.
Navin's bond on the murder charges was set at $2.5 million, while Valiante is being held on $2 million bail.
Authorities previously disclosed text messages in which Jeffrey Navin asked his son if he hurt his mother, and in which Jeffrey Navin expressed concern he was being framed for his wife's killing. The texts were sent the day the Navins vanished.
According to the arrest warrant affidavit for Valiante, Jeffrey Navin texted his son on Aug. 4 — the day he disappeared — saying he would not go home until his knew his wife was OK. The father also asked his son if he hurt his mother.
"No absolutely not. Why would you think," Kyle Navin responded, according to the affidavit.
"I go home and get framed for murder," Jeffrey Navin then texted.
"Oh stop," Kyle Navin texted back.
Kyle's younger brother, Taylor, who lives in Mississippi, was also interviewed by police, according to the arrest affidavit for Valiante.
When police said his brother was a person of interest in his parents' disappearance, he responded: "When I heard my parents were missing I thought to myself, 'they either went on vacation, or my brother did something to them.'"
