Death at the Border

The Fifth Estate investigates the murky world of human smuggling after a family of four from India, including a toddler, froze to death earlier this year trying to cross from Manitoba into Minnesota.

The investigation reveals an alleged human smuggler who had been under surveillance by U.S. Homeland Security for years, is now being investigated in connection with the family's death, raising questions about whether more could have been done to save the family.
