A dive team called in by the RCMP has finished searching 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 small body of water on a private property between Niton and Nojack, just off Highway16 and Range Road 120.

Three divers entered a dugout early Tuesday in part of a search that began last week. Loud sounds could also be heard through the thick trees nearby after an industrial vacuum truck showed up at an adjacent acreage, which is home to some renters and their horses. A large hose was used to suction out a septic tank, which the divers were also asked to inspect.

On the weekend, 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.

Investigators have remained tight lipped about what they've found.

The 80-acre piece of land has been linked to a past acquaintance of Travis Vader who has been named a suspect in the case. The property is littered with abandoned vehicles and other discarded items.

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.

A $60,000 reward is available to anyone who leads police to an arrest and conviction of the person responsible for the couple's disappearance.
