Images show the search for a missing man in the marshy area of the St. Lawrence River, where eight migrants were found dead. Casey Oakes, a 30-year-old last seen operating a boat near the site of the bodies, has yet to be located. The police are working with Immigration Canada and the U.S. Department of Homeland Security to verify the identities of the deceased. The Akwesasne Mohawk Police have not connected Oakes to the deaths. The territory, which straddles the Canada-U.S. border, has seen high levels of human smuggling, with authorities intercepting 80 people trying to enter the U.S. illegally this year alone.
