Dulos, 52, was arrested for the second time Wednesday for tampering with evidence following an arrest in June, for separate charges of tampering with evidence and obstruction of prosecution . His 44-year-old girlfriend, Michelle Troconis, who was charged with the same counts in June, was also arrested this week, about 24 hours after Dulos, for falsifying evidence.

Nearly identical arrest warrants for the pair launched by the Connecticut State Police indicate that Troconis was interrogated three times by investigators, but that is only when his last interview on August 13 that she admitted "during her two previous interviews with the police been truthful."

The police confronted Troconis with a host of evidences, including surveillance footage of the day Jennifer disappeared and days later. Police determined that Dulos, a real estate developer, had taken the red Toyota pickup truck from an employee of one of his company's properties in Farmington the very morning of Jennifer's disappearance, according to the warrants d & # 39; stop.

This Toyota van is seen in a surveillance sequence moving between Farmington and New Canaan, where Jennifer lived, the morning of her departure. Another camera surprised the van parked 100 feet from the place where Jennifer's 2017 Chevrolet was found later that day, abandoned and with visible bloodstains.

Another photo, taken a few minutes later and showing Jennifer driving her Chevrolet home after dropping her kids off at school, "is the last known photograph of Jennifer alive," according to the order. stop. "At the moment this footage was recorded, it is thought that Dulos was waiting … for his wife to come home."

"The crime and the cleansing would have taken place between 8:05 and 10:25," said the warrants. At 10:25 am, home surveillance surprised Jennifer's 2017 Chevrolet being chased from her home.

"Dulos is believed to be operating the victim's vehicle carrying Jennifer Dulos's body and several other items related to the cleanup that took place in the residence's garage," the warrants said. Investigators have previously stated that Dulos' DNA was found mixed with Jennifer's blood at home.

Jennifer's mobile phone data indicates a move from her home to where the Toyota red van was parked, according to the arrest warrant. The red pickup, owned by Dulos employee Pawel Gumienny, is seen on a surveillance video leaving New Canaan just after 11 am.

Gumienny told the investigators that Dulos had taken the van to a construction site. When Gumienny located Dulos, Troconis and his truck on a different job site later in the day, Troconis left with the keys of the Toyota and Dulos tried to convince his employee to take a company car for the Memorial weekend Day.

Gumienny refused and Troconis returned with the keys. But Dulos and Troconis took the truck the next week to clean and clean it, Gumienny told the police. The police checked Gumienny's account with the help of a car wash monitoring sequence, according to the warrant.

Dulos also started asking Gumienny to replace the Toyota seats, which Gumienny did not understand, but he did it anyway because Dulos was "invading" and "getting angry," Gumienny told reporters. investigators.

Dulos provided spare seats from Jennifer's Porsche and asked Gumienny to dispose of the old seats "so that they would not be found", according to the arrest warrant.

But Gumienny kept his old seats and on June 6, he handed them over to the police.

Forensic tests have established a connection between a blood-like substance on the passenger seat and Jennifer's DNA, according to the arrest warrant.

On August 13, Troconis confessed that she had gone with Dulos to bring the Toyota for her to be washed and detailed, specified the arrest warrant. When the police asked her why she thought her boyfriend had taken her employee's truck for a $ 250 service, she replied, "Well, of course … all the evidence indicates that … you are 39, showed the picture of the blood in the door, that's because Jennifer's body at one point was there. "

She told police that before Gumienny came to pick up the truck on May 24, she had seen Dulos clean the truck of what he described as spilled coffee.

"Troconis told the investigators that Dulos had handed her a stained towel" and that she "claimed not to remember the color of the stain, but she admitted that the towel did not smell coffee", specified the mandate.

When asked why she had taken Gumienny's keys, she replied to the police that there was "no reason".

She also said that she had lied saying that she was with Dulos the morning of May 24 and that in reality she did not know where he had gone. "The initial complaint was inaccurate while it appeared in the" scenario "prepared by Dulos and perpetuated by Troconis during his first interview," said the arrest warrant.

The investigators found the "alibi scripts" at Dulos. Troconis admitted that she herself and Dulos had written the notes, which "included information, which subsequently turned out to be inaccurate, of events that Troconis was forced to admit during her interrogation and who did not." "The scripts" had never been produced, including alibi witnesses who were subsequently found to be false, "said the arrest warrants.

The notes also omitted "any incriminating behavior". Investigators have previously reported that Dulos and Troconis were seen on a surveillance video on May 24 in Hartford, where they concealed objects that would later be identified as containing Jennifer's blood.

Mobile phone data also indicated that Dulos and Troconis were in Hartford later the day Jennifer disappeared, but Dulos had left his phone behind him that morning, while he was still wearing it.

Troconis' lawyer, Andrew Bowman, insisted Thursday that his client is innocent. "Do not forget that Michelle is presumed innocent and that she should be," Bowman said. "We are ready to leave judgment in this case in the hands of a jury."

Troconis was released Thursday with a deposit of $ 100,000. She is scheduled to appear in court on September 18.

Dulos was released on bail of $ 500,000 and is scheduled to appear in court on September 12. On leaving prison on Wednesday, he declared that he was participating in "an exhausting struggle," adding, "I love my children – that's about it all."

His lawyer, Norm Pattis, said his client would plead not guilty to the new charge.

"Apparently, Michelle has changed tone and a handyman is telling him to distract himself from attention," Pattis said. "We want the state police to spend more time searching for Jennifer and less trying to file against Fotis."
