Kyle Navin and his Westport girlfriend Jennifer Valiante were in the same Bridgeport courthouse Tuesday for only the second time since they were arrested for conspiring to kill Navin’s parents, the owners of J&J Refuse of Westport.

But there was no reunion.

Held on different floors of the state Superior Court building, the couple who first met while attending Staples High School, were brought before Judge Robert Devlin more than an hour apart.

Valiante, 31, leaning toward the microphone at the defense table stated: “Not guilty, your honor,” when asked how she pleaded to the charges of conspiracy to commit murder and hindering prosecution. She chose a trial by jury.

Navin, 27, remained mute as his lawyer, Eugene Riccio, asked for a continuance to decide whether they will seek a hearing on probable cause.

Navin will be back in court Dec. 16, while Valiante will return Jan. 12. Both were then taken back to separate sites of incarceration -- he to a prison in Rhode Island, she to the state’s prison for women in Niantic.

State’s Attorney John Smriga characterized the documented evidence against Navin and Valiante as “voluminous.”

Valiante’s lawyer, Elliot Warren, later said he wants to study as much of the state’s case as he can before seeking to have his client’s $2 million bond reduced.

“I have to attack the probable cause in the warrant and if I can do that I may be able to get the bond lowered,” Warren said. “She is doing as well as can be expected, she is working through the routine there (in prison). It’s difficult for her and it’s difficult for her family.”

Valiante’s grandfather and aunt were sitting in the back of the courtroom during the brief hearing. They declined comment.

Warren said his client maintains her innocence. He said prior to her arrest there were attempts by the police to convince her to cooperate in the investigation against her boyfriend but that is now ended.

Kyle Navin is being held in lieu of $2.5 million.

Jeffrey Navin, 56, who was president of J&J Refuse and his wife, Jeanette Navin, 55, a Weston Intermediate School library paraprofessional, disappeared from their Easton home Aug. 4. Their bodies were found buried beneath debris in Weston on Oct. 29.

Police said Kyle Navin, who has a drug habit, killed his parents with his girlfriend’s help to get their money.

Two weeks before her disappearance, Jeanette Navin tearfully told a friend she was at wits end with her eldest son, according to the arrest warrant affidavit. She and her husband planned to cut Kyle out of their will, she told the friend, and were going to sell their trash-collection business.

“Kyle will be on his own without any financial support from the family,” the affidavit states.

The warrant affidavit reveals alarming texts between Kyle Navin and his girlfriend weeks before his parents vanished.

“I was trying not to punch (his father) in the face and get arrested because if I do punch him I won’t be able to stop,” Kyle Navin texted Valiante.

“We need to figure out what the best way to take them down whether it is get some money out of them somehow (expletive) him at the business the house something we got to figure out I’m got to be real smart and do it quick.”

And later: “It would solve every single problem and give us a wealthy amazing life.”

The warrant states that police found two bullet holes in the front passenger seat of Kyle Navin’s blue 2000 pickup truck at a commuter lot in Westport. The portion of the seatbelt that crossed over the chest of the passenger also had a bullet hole in it. Jeannette Navin’s blood was found on the seat.

Blood stains were also found on the basement floor of Kyle’s Navin’s house in Bridgeport, matching his father’s blood, the affidavit states.
