Murders of Lyle and Marie McCann  Lyle and Marie McCann were last seen on July 3, 2010, while on a road trip from their hometown of St. Albert, Alberta, to Chilliwack, British Columbia. A few days later, their charred motorhome was discovered, resulting in a search that led to the arrest of Travis Vader. Vader was eventually charged with second-degree murder in the deaths of the McCanns, though their bodies have yet to be discovered. Vader was found guilty on September 15, 2016. On October 31, 2016, the second-degree murder conviction was reversed and Vader was convicted of manslaughter. Lyle Thomas McCann was born August 24, 1931, near Red Deer, Alberta, one of six children. Marie McCann (née Waltz) was born October 15, 1932, in Torrington, Alberta, one of seven children. They were married July 30, 1952, in Torrington, and have resided in St. Albert since 1964. Lyle was a long-haul truck driver for many years, traveling throughout North America. They had three children. Lyle and Marie were 78 and 77 years old, respectively, at the time of their disappearance. On July 3, 2010, the McCanns left St. Albert for Chilliwack for a vacation and were to pick up their daughter on July 10 at the Abbotsford International Airport. That same day they were seen at a Superstore gas station fueling up their 1999 Gulfstream Coach motorhome in St. Albert, with their green Hyundai Tucson in tow. They are then believed to have traveled to the Yellowhead Highway. In the evening of July 5, firefighters responded to a motorhome on fire at the Minnow Lake campground near Edson, Alberta. No bodies were found, but police discovered the motorhome belonged to the McCanns, though the Hyundai Tucson was missing. The Royal Canadian Mounted Police (RCMP) visited the McCanns' home, but received no answer. When the McCanns did not arrive in at Abbotsford International Airport on July 10, their daughter, Trudy Holder, notified the RCMP, who released a missing persons notification. The RCMP realized the connection between the burned-out motorhome and the McCanns' disappearance and launched aerial and ground searches. On July 16, the RCMP found the McCanns' SUV near Highway 16 and Range Road 144, about 30 kilometres east of Edson. They soon announced that the disappearance of the McCanns appeared to be foul play. At the same time, the RCMP revealed a person of interest, 38-year-old Travis Edward Vader of no fixed address.
