Connecticut detectives looking for murdered mom of five Jennifer Dulos returned to a house owned by her late husband in a renewed search effort Tuesday, police confirmed to The Post.

Detectives are combing the sprawling Mountain Spring Road home in Farmington once owned by Fotis Dulos’ homebuilding company, Connecticut State Police said.

It is the same property where Fotis — who died by suicide while accused of his wife’s death — spent several hours on the last day his wife was seen before her disappearance in May 2019, the Connecticut Post noted.

The paper said the search was arranged because the 10,000-square-foot home is under contract to be sold, having been listed for almost $1.7 million.

Officially, state police would only say that it was “for investigative purposes” and “following up on old leads.”

More than a dozen troopers, some with police dogs, were seen walking in and around the property, the Hartford Courant said, noting the property has been searched numerous times before.

Fox 61 said that a ground scanner was being used to map out the area.

Jennifer Dulos, 50, has long been assumed to have been murdered — with blood found in the garage of her New Canaan home suggesting she was “violently assaulted,” cops have said.

Her estranged husband had been formally accused of killing his wife, but died by suicide in January last year hours before he was due to appear in court in Stamford.

The couple had been enmeshed in a lengthy and bitter divorce before her disappearance.

Fotis’ girlfriend, Michelle Troconis, and lawyer, Kent Mawhinney, both still face charges in the case.
