Police have now called in a dive team to help search a small body of water on a rural property west of Edmonton in relation to the disappearance of St. Albert couple Lyle and Marie McCann.

The dive team has been called to the small body of water on a private property between Niton and Nojack, just off Highway16 and Range Road 120.

The squad's search, which is scheduled for Tuesday, comes a day after  a ground search wrapped up at the site where a forensics team removed a garbage bag filled with unknown contents. Investigators were also seen going into a specific area with a camera.

But investigators are remaining tight lipped about what they've found.

"At this point I am not privy to what was seized at this property," said Sgt. Tim Taniguichi with the RCMP.

The piece of land has been linked to a past acquaintance of Travis Vader who has been named a suspect in the case. 

People living in the region say RCMP have been on scene a number of times over the past several weeks and have also searched other nearby properties.

The missing couple left for B.C. on July 3rd and have not been seen or heard from since.

The McCanns' burned-out motor home was found on July 5th near the Minnow Lake campground approximately 35 kilometres southeast of Edson. On July 16th, their green Hyundai SUV was located deep in the bush about 30 kilometres east of Edson near Carrot Creek.

Vader was arrested in mid-July on charges unrelated to the couple's disappearance. Vader was picked up by officers at a rural residence near Niton Junction.
