(CBS NEWS)- The father of one of the suspects in the slaying of an American woman, her Australian boyfriend and another man said Wednesday he expects a nationwide manhunt to end in the death of his son, who he said is on “a suicide mission.” The grim prediction came as Canadian police said they were setting up roadblocks around the remote Manitoba town of Gillam, where two young suspects, 19-year-old Kam McLeod and 18-year-old Bryer Schmegelsky, recently left a burned-out vehicle they had been traveling in.

Royal Canadian Mounted Police Cpl. Julie Courchaine said police “are coming from all over” to Gillam, which is more than 2,000 miles away from a region in northern British Columbia where another burned vehicle was found Friday and where the three people were apparently killed.

The victims have been identified as American Chynna Deese, 24, Australian Lucas Fowler, 23, and Leonard Dyck, 64, of Vancouver. Police released Dyck’s name late Wednesday and announced that McLeod and Schmegelsky have been charged with second-degree murderin his death.
