A Central American migrant sleeps on top of a freight train to travel to north Mexico to reach and cross the US border, in Arriaga in the state of Chiapas, Mexico, Jan. 10, 2012. Hundreds of thousands of migrants, mostly Central Americans, risk robbery, death from fast-moving freight trains, or dehydration in the desert while trying to reach the US illegally.
