The RCMP say no human remains were found in the yard of a home in Shad Bay after investigators spent days combing the property.

Sunday morning, police confirmed the Prospect Road search was connected to a missing person cold case, and they were looking for human remains.

Police spent four days at the site. They used cadaver dogs, excavators, and shovels to dig up the backyard.

Police spoke to the media for the first time Sunday, after days of being tight-lipped about their work at the home. They wouldn’t specify whose remains they believed may be at the home.

Sgt. Al LeBlanc said they will continue to follow leads in the case, but he wouldn't say which case it was. LeBlanc also wouldn’t reveal what lead them to the house.

The property at 4117 Prospect Road is owned by Thomas Arthur Johnson. The Johnson family has owned the house for decades.

McAndrew connection

There’s been speculation the case was connected to the disappearance of Kimberley McAndrew. The 19-year-old was last seen in August 1989, when she was leaving her job at Canadian Tire on Quinpool Road in Halifax.

The McAndrew family told CBC Saturday they heard from the police, but the RCMP did not confirm a connection between the two cases. Instead, police were warning the family they may hear from the media in the coming days.

"We're not going to provide specifics of this investigation," said LeBlanc when asked about the McAndrew connection. "We don't want to speculate."

He said investigators may be prepared to release more information Monday.
