Her estranged husband, Fotis Dulos, and his girlfriend, Michelle Troconis, were arrested on charges of tampering with evidence and hindering prosecution in connection with Jennifer's disappearance.

[4] Police believe Fotis lay in wait for Jennifer, attacking her when she returned home after dropping her children off at school.

[citation needed] Fotis Dulos (August 6, 1967 – January 30, 2020) was born in Turkey and grew up in Athens, Greece, moving to the U.S. in 1986.

That year Dulos founded Fore Group Inc., a real estate development company based in Connecticut, specializing in luxury homes.

[8] They had five children together, including two sets of twins, all named after Greek Orthodox saints – three sons: Petros, Theodore, and Constantine; and two daughters: Christiane and Cleopatra Noelle.

[9][10] In a 2012 blog post, Jennifer alluded to trouble in her marriage: "I wish I were a strong person and that confrontation did not both scare and appall me.

"[11] After the gradual breakdown of the marriage, in which Jennifer claimed Fotis was living an increasingly independent life, she filed for divorce in 2017, at Superior Court in Stamford.

[19] Jennifer was last seen at around 8 a.m. on May 24, 2019, when she dropped her children off at New Canaan Country School, and then at 8:05 on a neighbor's security camera returning home.

[5] Almeida, who had arrived at the house at 11:30 a.m. that day, later told detectives she was surprised to see Jennifer's Range Rover in the garage because she had planned to take it to her doctors' appointments instead of her Chevrolet Suburban, which was missing.

[21] When detectives searched the house, they found blood spatter on the floor, door and a wall in the garage, as well as on the exterior of the Range Rover.

According to authorities, Fotis was the one driving the victim's vehicle, carrying the body of Jennifer and other items associated with the probable cleanup.

[22] That same evening, at around 7:30 p.m., Fotis and Troconis were captured on video dumping garbage bags in thirty bins in Hartford.

Investigators believe he arrived by bike at Jennifer's home due to tire marks found and other evidence.

[24] In January 2021, the Connecticut State Police visited property on Mountain Spring Road in Farmington, which was once owned by Fotis's real estate company, to follow up on "old leads".

[25] In October 2020, her family sought to have her declared legally dead; the request was denied five months later as the seven-year deadline required under Connecticut law since she was last known to have been alive had not elapsed.

[26] On June 1, 2019, Fotis and Troconis were arrested at a hotel in Avon, Connecticut, and charged with tampering with evidence and hindering prosecution.

[21] The Dulos' five children, then aged between 8 and 13, moved to New York City to live with Jennifer's mother, who was granted temporary custody.

Fotis's friend and former attorney, Kent Douglas Mawhinney, was also arrested that day and charged with conspiracy to commit murder.

After Jennifer disappeared, a shallow grave was discovered at a secluded property that Mawhinney owned, filled with two bags of lime and a blue tarp.

He was found in an unresponsive state by police at his home in Farmington, having poisoned himself with carbon monoxide by running a vacuum-cleaner hose from the exhaust pipe of his SUV into the interior of the car while it was parked in his garage.

[49] In May 2021, a domestic violence bill – "Jennifers' Law" – received near unanimous support in the Connecticut State Senate.
