Autopsy results say carbon monoxide poisoning is what killed two people near Hay River, N.W.T. last weekend. 

RCMP found the bodies of Brenda Laviolette-Rapp, 58, and Robert Bradley, 52, late Sunday evening.

They were in a cabin at the Mountain Aven Campground.

The N.W.T. Coroner's Office says it's still early in the investigation, but it's looking into how propane was used in cabin and whether or not everything was up to code.
