NEW CANAAN, Conn. (CBSNewYork) -- Two people have been arrested in the disappearance of missing Connecticut mother Jennifer Dulos.
Her estranged husband, Fotis Dulos, and his girlfriend, Michelle Troconis, were picked up in the town of Avon and charged with tampering with physical evidence and hindering the prosecution.
Jennifer Dulos, a 50-year-old mother of five, disappeared on May 24 after dropping her kids off at New Canaan Country School. Her black Chevrolet Suburban was found abandoned near Waveny Park.
On Friday, sources told CBS2 affiliate WFSB the week-long search had turned into a homicide investigation because the New Canaan resident's blood was found. It's not clear where.
Jennifer Dulos was reportedly in the middle of a divorce and custody battle.
According to court documents, she said, "I am afraid of my husband… I know that filing for divorce will enrage him. I know he will retaliate by trying to harm me in some way."
She also accused him of infidelity, cruelty and threatening to kidnap their children and bring them to Greece.
Fotis Dulos denied the allegations.
On Sunday, CBS2's Lisa Rozner was outside St. Mark's Episcopal Church in New Canaan, where a vigil for people of all faiths was held for the missing woman.
"It was beautiful. It was a beautiful tribute and it shows the unity of us all in this town," New Canaan resident Wendy Lynch said.
"It frightens us and we're here to support the family," added Jill Riith of nearby Darien.
There was also an outpouring of support from classmates of her five children, who range in age from 8 to 13.
Aaron Cooper, the head of New Canaan Country School, described Jennifer Dulos as, "an incredibly warm person, as an unbelievably devoted mother, as an active member of our community."
The children are now in the care of their maternal grandmother at her Fifth Avenue home in Manhattan. Kate McConoughey said she grew up with Jennifer Dulos in Brooklyn and is praying for her safe return.
"She was so nice. She got along with everyone, which really meant a lot to me because I didn't get along with everyone," McConoughey said.
Rev. Peter Walsh, the pastor at St. Marks, did not address the new arrests, but said the vigil was a way to offer healing to anyone affected by the case.
"The pain ripples deeply into the community and creates a tremendous amount of anxiety that goes way beyond whether or not people know the family," Rev. Walsh said.
The search has expanded across several towns and even to Jennifer Dulos' parents' estate in the affluent town of Pound Ridge in Westchester County. There has also been a heavy police presence at a home in Farmington, Conn. -- located west of Hartford -- that is linked to the construction company of her estranged husband, Rozner reported.
"It's just painful. I am afraid that they won't find her," New Canaan resident Gail Merrill said.
Both Fotis Dulos and the girlfriend are being held on $500,000 bond. They are both scheduled to appear in Norwalk Superior Court at 10 a.m. on Monday. Police said as the criminal investigation progresses, additional charges can be expected.
