UPDATE: Friday November 19 – The family of Lyle and Marie McCann have temporarily called off their ground search for the couple, due to snow. Their search will resume in the spring when weather conditions improve.

77-year old Marie McCann and 78-year old Lyle McCann were last seen on July 3, 2010. The couple was planning on travelling from their St. Albert home in their motorhome, making stops along the way. The were to meet their daughter Trudy Holder at the Abbotsford airport on Saturday July 10 – but Marie and Lyle never showed up. The couple’s family called the police immediately and reported them missing.

In the meantime, police had been called to a campground near Edson, Alberta, where a motorhome was found engulfed in flames. When the missing persons report was filed on July 10, police linked the two cases together, and discovered it was the motorhome of Marie and Lyle McCann. No bodies were found in the motorhome, and the couple’s light green Hyundai Tucson could not be found until Friday July 16.
