Who Killed American Woman and Her Boyfriend Along Alaska Highway in Canada?

Chynna Deese, 24, and her Australian boyfriend, 23-year-old Lucas Fowler, were found dead last week on the side of Alaska Highway 97 in a remote part of Canada. They had reportedly been fired at, the back window of their blue Chevy blown out by a shotgun blast. Police are also investigating a possible link between the couple's deaths and the disappearance of two teens, and the discovery of an unidentified body, in the same region.
