Police questioned the estranged husband of missing Connecticut mom Jennifer Dulos and his girlfriend at the man’s mansion, according to a published report.

Cops in unmarked cars showed up at Fotis Dulos’ Farmington mansion Friday around 6 pm and stayed for about 30 minutes, the Daily Mail reported. Dulos and his girlfriend left in their own car, followed by police. Police said no arrests were made, according to the Daily Mail.

Earlier in the day, authorities were seen searching a pond in Waveny Park, not far from where Dulos’ black Chevy Suburban was found.

The 50-year-old mom of five was reported missing on March 24 amid a contentious custody battle with her 51-year-old husband.

Dulos said in divorce papers she feared he would “retaliate by trying to harm me in some way.” She had been fighting Dulos for full custody of her kids, who range in age from 8 to 13. The children are currently staying with Dulos’ mother in Manhattan.

The family released a statement Friday saying they are “hopeful” she will return home.

“We miss her beyond measure,” the statement said.
