A missing mother of five's estranged husband and his girlfriend are set to make their first court appearances in Connecticut after being charged with evidence tampering and hindering prosecution .
Fotis Dulos and Michelle Troconis are scheduled to be arraigned Monday at Norwalk Superior Court.
Both were arrested Saturday night in connection with the investigation into the May 24 disappearance of 50-year-old Jennifer Dulos in New Canaan. She was last seen dropping off her children at school and is still missing.
Details of the charges have not been released.
Jennifer and Fotis Dulos have been embroiled in a contentious divorce and child custody case for the past two years. It wasn't clear if Dulos and Troconis have criminal court lawyers who could respond to the allegations.
