State police Tuesday visited a property on Mountain Spring Road in Farmington once owned by Fotis Dulos' Fore Group, Inc.
State police said they were at the location for investigative purposes, following up on old leads.
Several detectives were seen in a wooded area behind the home.
Police brought in an expert from New Hampshire to search the area with ground penetrating radar. Bob Perry, who is known nationally as "The Bone Finder," told NBC Connecticut he was at the Mountain Spring Road property on Tuesday.
He would not say if he and police found anything.
Their presence comes nearly a year after Dulos died by suicide. He was accused of murdering his wife, Jennifer Dulos, who went missing in May 2019 and has never been found. The last sighting of her was when she dropped her children off at school in New Canaan that morning.
Police who initially searched for Jennifer Dulos found blood at her New Canaan home.
