Investigators in the Jennifer Dulos case returned with an excavator and a septic truck Wednesday to the same Farmington property they searched Tuesday.

Connecticut State Police gave a brief statement, but say because the investigation is active and ongoing, they can't give any specifics except to say they're following up on old leads in their search for Dulos.

Chopper 12 captured the excavator above the scene at 80 Mountain Spring Road digging in the woods behind the home. Law enforcement officers were also seen digging with shovels in the same area Tuesday.

"Our Western District Major Crime Squad detectives have been on the property following up on leads," says trooper Josue Dorelus.

The excavator was at the site for a few hours before leaving when the septic truck came in. It came one day after dozens of law enforcement officers descended on the home to search for Jennifer Dulos' remains, bringing with them K-9s and ground penetrating radar.

Investigators have been at the property before, including in the days right after May 24, 2019 - when Jennifer Dulos disappeared.

The home used to be owned by the homebuilding company of her estranged husband, Fotis Dulos, and it was mentioned in his arrest warrant. Police believe Fotis Dulos killed Jennifer Dulos in the garage of her home, then got rid of the body somewhere.

They're still looking for where - but even without a body, Fotis Dulos was charged with her murder last January. He killed himself a few weeks later, maintaining he wasn't involved.

Michelle Troconis, Dulos' former girlfriend, and Kent Mawhinney, his attorney, have been charged as co-conspirators in the case.

State police maintained this investigation remains active and ongoing.

"Our main goal is again to work towards providing the family of Jennifer Dulos some closure, and our detectives will continue to work tirelessly in the direction of doing so," says Dorelus.

The property is on the market and appears to be close to being sold. It's listed as contingent, meaning an offer has been made and accepted but certain conditions have to be met before the deal goes through.

It's possible the new search is connected to that.
