I'm wondering if the human trafficker left them off near the border so he wouldn't be caught with them and pointed them in the general direction and they got disoriented and lost in the dark, snowy landscape.
"The people found dead on Wednesday would have faced bitter cold, endless fields, large snowdrifts and complete darkness crossing the international border on foot, said RCMP Assistant Commissioner Jane MacLatchy."
More than likely dropped them off knowing they’d freeze out there in the tundra.
