MBtv: The end of a perilous journey for migrants from Central America

Apprehensions of undocumented migrants on the US border with Mexico soared 70 percent in March, hitting the highest level in 15 years.

Sometimes just a few days later, some of them are released and make the final leg of a perilous journey, to be reunited with their loved ones already living in the US.
