HARTFORD, Conn. (AP) Police investigating the disappearance of a Connecticut mother of five have arrested her estranged husband and his girlfriend on charges of evidence tampering and hindering prosecution, authorities announced Sunday.

Police in the wealthy New York City suburb of New Canaan said Fotis Dulos, 51, and Michelle Troconis, 44, were taken into custody in Avon, Connecticut, late Saturday. Both were detained on $500,000 bail and are scheduled to be arraigned Monday in Norwalk Superior Court.

Jennifer Dulos, 50, of New Canaan, went missing May 24 after dropping her kids off at school and missing appointments that day. She has not been found.

Police have searched locations in several towns including a park in New Canaan where Jennifer Dulos vehicle was found and a home in Farmington where Jennifer Dulos and her children, who range in age from 8 to 13 and include two sets of twins, had lived until about two years ago. Fotis Dulos has continued to live at the Farmington house.
