Real estate developer Fotis Dulos and his girlfriend Michelle Troconis, were arrested on Saturday related to the disappearance of Jennifer Dulos, 50
Fotis is the estranged husband of  Jennifer Farber Dulos, with whom he is locked in a custody battle over their five children after a 14-year marriage
Fotis, 51, and Troconis, 44, both have been charged with hindering prosecution and tampering with evidence, and Troconis has been booked on similar charges 
Some 20 state police units including half a dozen K9 units began searching a second Farmington property owned by Fotis’s company, The Fore Group, on Sunday morning
The search efforts concentrated around  the back of the 80 Mountain Spring property, next to a wooded area
Authorities obtained a search warrant for the the estranged couple’s primary residence at Jefferson Crossing home  in Farmington on Friday
After filing for divorce, Jennifer and her children moved from the family’s luxury home in Farmington to a home she rented in New Canaan, Ct., in June 2017
Jennifer was last seen leaving her children at day care on May 24, four days before Fotis sought sole custody
After they were questioned, Fotis and Troconis were taken to a police station where they gave DNA samples
