STAMFORD, Conn. (AP) — Family and friends of Jennifer Dulos, who disappeared from her Connecticut home in 2019, offered emotional testimony Friday at the sentencing hearing of her estranged husband’s former girlfriend, who was convicted of helping to plan and cover up her killing.

Michelle Troconis, 49, faces up to 50 years in prison.

Prosecutors say Dulos’ husband, Fotis Dulos, killed her at her home in New Canaan and drove away with her body, which has never been found. He died by suicide in 2020 shortly after being charged with murder. He had denied killing his wife.

Troconis was Fotis Dulos’ girlfriend and was living with him at the time Jennifer Dulos vanished. Troconis was convicted by a jury in March of conspiracy to commit murder, hindering prosecution and evidence tampering.

Troconis insists she is innocent and intends to appeal her convictions. She is detained at the state women’s prison. Her family and friends, who were angry and heartbroken after she was convicted, are also expected to testify Friday.

The sentencing comes five years and one week since Jennifer Dulos disappeared after dropping her five children off at school, on May 24, 2019.

About 80 people packed the courtroom, with Jennifer Dulos’ family and friends on one side and Troconis’ supporters on the other. All five of Dulos’ children, as well as her mother, Gloria Farber, attended. They spoke of their heartbreak and anger.

Farber said she knew “something terrible had happened” when her daughter did not return calls or texts on that day. She said her daughter “only wanted to give and get love and be a loving mother” to her children, who are now teenagers.

The oldest child, 18-year-old Petros Dulos, said his mother’s death has left him with “a hole inside of me that I know I will never fill.”

He said he had been close to his mother but struggled during his parents’ divorce.

“The defendant’s actions mean that I will never be able to tell my mom how sorry I am for not being a better son when she needed me,” he said.

Lauren Almeida, the Dulos family’s nanny, said she and Dulos’ friends had been afraid for the safety of themselves and the children after her disappearance.

Almeida asked Troconis, “Where is she, Michelle?,” referring to Dulos’ body.

The case was the subject of news documentaries and a made-for-TV movie, Lifetime’s “Gone Mom.”

Jennifer Dulos was a member of a wealthy New York City family. Her father, the late Hilliard Farber, founded his own brokerage firm, Hilliard Farber & Co., after running Chase Manhattan Bank’s bond trading desk. She also was a niece, by marriage, of fashion designer Liz Claiborne.

“We miss her every day, in every way,” some of her relatives and friends said last week in a statement released by Dulos’ friend, Carrie Luft. “For us, five years is not a milestone but a marker of cumulative loss and longing. Life goes on, yet grief goes on alongside it, a shadow, a current, the presence of absence.”

Troconis, a dual American and Venezuelan citizen, said she co-founded a horse-riding therapy program, once had her own TV production company in Argentina, and hosted a snow-sports show for ESPN South America. Fotis Dulos was a luxury home builder from Greece.

Her lawyer, Jon Schoenhorn, did not return messages seeking comment. When Troconis was convicted in March, he said he couldn’t understand how the jury reached guilty verdicts.

Troconis’ family, including her parents and sisters, expressed the same disbelief.

“Choosing and putting my sister as the guilty person is not the right thing to do because she is innocent,” Claudia Troconis-Marmol said tearfully outside the courthouse shortly after the convictions.

Authorities suggested Fotis Dulos killed his wife because of his growing frustration with their divorce and child custody proceedings.

At the time, Jennifer Dulos was living with the children in New Canaan while Fotis Dulos stayed in the family’s 10,000-square-feet (929-square-meter) home about 70 miles (115 kilometers) away in Farmington.

Hours after Jennifer Dulos was last seen alive, Troconis was recorded on surveillance video accompanying Fotis Dulos on a trip to Hartford, where he discarded trash bags from the back of his pickup truck. Police later found some of the bags after seizing Fotis Dulos’ cellphone, looking at its location data and obtaining the surveillance video from the locations.

In one of the most jarring moments in Troconis’ trial, the prosecution and state forensic experts showed a shirt, bra and zip ties with blood-like stains on them that were found in one of the trash bags. Testing showed that DNA on the items was highly likely that of Jennifer Dulos.

Troconis told police she didn’t know what was in the bags or why Fotis Dulos was dumping them in Hartford.

Prosecutors also said Fotis Dulos left his cellphone at his home on the day Jennifer Dulos vanished and Troconis answered a call to it from his friend that morning. They say that was evidence Troconis was in on the plot and tried to help him create a bogus alibi. She denied the allegation.

Another defendant in the case, Kent Mawhinney, a friend of Fotis Dulos and his one-time lawyer in a civil case, is awaiting trial on a murder conspiracy charge. He has pleaded not guilty.

Although Jennifer Dulos’ body has never been found, a probate judge declared her legally dead last year. The Dulos children have been in the custody of Jennifer Dulos’ mother in New York City since she vanished.
