UPDATE 1-Canadian air force joins search for fugitive murder suspects in remote area

Canada's air force has been called in to a tiny community in northern Manitoba, where two teens suspected of three murders were thought to have been last seen, police said on Monday, as the chase entered a second week. Kam McLeod, 19, and Bryer Schmegelsky, 18, were believed to have been seen on Sunday outside York Landing, a First Nations community of less than 500 people, 90 km (56 miles) south of Gillam, Manitoba, where search efforts were previously concentrated.
