Jennifer Dulos, 50, was reported missing in New Canaan, Connecticut, on May 24, 2019.

NORWALK, Conn. – A missing Connecticut mother's estranged husband and his girlfriend are both being held on $500,000 bail after their first court appearances since being charged with evidence tampering and hindering prosecution.

Fotis Dulos and Michelle Troconis did not enter pleas as they were appeared for the charges Monday, June 3 at Norwalk Superior Court, where a prosecutor said more charges are expected to be filed.

Both were arrested Saturday night in connection with the investigation into the May 24 disappearance of 50-year-old Jennifer Dulos in New Canaan. Jennifer Dulos, a mother of five, was last seen dropping off her children at school and remains missing.

The search for Jennifer Dulos brought police to Pound Ridge, a town about 8 miles from the house that Jennifer Dulos rented and lived in with her five children, according to reports. Her 85-year-old mother lives in Manhattan but owns a house in Pound Ridge.

Jennifer and Fotis Dulos have been embroiled in a contentious divorce and child custody case for the past two years.
