Halifax RCMP remain tight-lipped about their search of a property on Prospect Road in the community of Shad Bay.
By Saturday police and forensic investigators were well into their third day of searching.
Sgt. Alain Leblanc would only say officers and the medical examiner are searching a residence and surrounding property in Shad Bay in relation to an ongoing investigation.
"We are not going to comment on speculation regarding our investigation and its focus in order to protect its integrity," he said.
There's a tent set up in the back of 4117 Prospect Road and officers have been seen emptying buckets of dirt from the scene, reported the CBC's Carolyn Ray.
Leblanc said officers will remain on the property as long as required.
Police have contacted the family of Kimberly McAndrew.
The 19-year-old vanished on Aug. 12, 1989.
Her family said police contacted them after media reports linked the Prospect Road search to McAndrew’s disappearance.
She left work at the Canadian Tire on Quinpool Road in Halifax after 4 p.m., and was last seen at a flower shop in Penhorn Mall in Dartmouth.
CBC News has determined the property in question is owned by Thomas Arthur Johnson.
